It does not aim for maximum +compression, or compatibility with any other compression library; instead, +it aims for very high speeds and reasonable compression. For instance, +compared to the fastest mode of zlib, Snappy is an order of magnitude faster +for most inputs, but the resulting compressed files are anywhere from 20% to +100% bigger. (For more information, see "Performance", below.) + +Snappy has the following properties: + + * Fast: Compression speeds at 250 MB/sec and beyond, with no assembler code. + See "Performance" below. + * Stable: Over the last few years, Snappy has compressed and decompressed + petabytes of data in Google's production environment. The Snappy bitstream + format is stable and will not change between versions. + * Robust: The Snappy decompressor is designed not to crash in the face of + corrupted or malicious input. + * Free and open source software: Snappy is licensed under a BSD-type license. + For more information, see the included COPYING file. + +Snappy has previously been called "Zippy" in some Google presentations +and the like. + + +Performance +=========== + +Snappy is intended to be fast. On a single core of a Core i7 processor +in 64-bit mode, it compresses at about 250 MB/sec or more and decompresses at +about 500 MB/sec or more. (These numbers are for the slowest inputs in our +benchmark suite; others are much faster.) In our tests, Snappy usually +is faster than algorithms in the same class (e.g. LZO, LZF, FastLZ, QuickLZ, +etc.) while achieving comparable compression ratios. + +Typical compression ratios (based on the benchmark suite) are about 1.5-1.7x +for plain text, about 2-4x for HTML, and of course 1.0x for JPEGs, PNGs and +other already-compressed data. Similar numbers for zlib in its fastest mode +are 2.6-2.8x, 3-7x and 1.0x, respectively. More sophisticated algorithms are +capable of achieving yet higher compression rates, although usually at the +expense of speed. Of course, compression ratio will vary significantly with +the input. + +Although Snappy should be fairly portable, it is primarily optimized +for 64-bit x86-compatible processors, and may run slower in other environments. +In particular: + + - Snappy uses 64-bit operations in several places to process more data at + once than would otherwise be possible. + - Snappy assumes unaligned 32- and 64-bit loads and stores are cheap. + On some platforms, these must be emulated with single-byte loads + and stores, which is much slower. + - Snappy assumes little-endian throughout, and needs to byte-swap data in + several places if running on a big-endian platform. + +Experience has shown that even heavily tuned code can be improved. +Performance optimizations, whether for 64-bit x86 or other platforms, +are of course most welcome; see "Contact", below. + + +Usage +===== + +Note that Snappy, both the implementation and the main interface, +is written in C++. However, several third-party bindings to other languages +are available; see the Google Code page at http://code.google.com/p/snappy/ +for more information. Also, if you want to use Snappy from C code, you can +use the included C bindings in snappy-c.h. + +To use Snappy from your own C++ program, include the file "snappy.h" from +your calling file, and link against the compiled library. + +There are many ways to call Snappy, but the simplest possible is + + snappy::Compress(input.data(), input.size(), &output); + +and similarly + + snappy::Uncompress(input.data(), input.size(), &output); + +where "input" and "output" are both instances of std::string. + +There are other interfaces that are more flexible in various ways, including +support for custom (non-array) input sources. See the header file for more +information. + + +Tests and benchmarks +==================== + +When you compile Snappy, snappy_unittest is compiled in addition to the +library itself. You do not need it to use the compressor from your own library, +but it contains several useful components for Snappy development. + +First of all, it contains unit tests, verifying correctness on your machine in +various scenarios. If you want to change or optimize Snappy, please run the +tests to verify you have not broken anything. Note that if you have the +Google Test library installed, unit test behavior (especially failures) will be +significantly more user-friendly. You can find Google Test at + + http://code.google.com/p/googletest/ + +You probably also want the gflags library for handling of command-line flags; +you can find it at + + http://code.google.com/p/google-gflags/ + +In addition to the unit tests, snappy contains microbenchmarks used to +tune compression and decompression performance. These are automatically run +before the unit tests, but you can disable them using the flag +--run_microbenchmarks=false if you have gflags installed (otherwise you will +need to edit the source). + +Finally, snappy can benchmark Snappy against a few other compression libraries +(zlib, LZO, LZF, FastLZ and QuickLZ), if they were detected at configure time. +To benchmark using a given file, give the compression algorithm you want to test +Snappy against (e.g. --zlib) and then a list of one or more file names on the +command line. The testdata/ directory contains the files used by the +microbenchmark, which should provide a reasonably balanced starting point for +benchmarking. (Note that baddata[1-3].snappy are not intended as benchmarks; they +are used to verify correctness in the presence of corrupted data in the unit +test.) + + +Contact +======= + +Snappy is distributed through Google Code.

It is originally based on +text by Zeev Tarantov. + +Snappy is a LZ77-type compressor with a fixed, byte-oriented encoding. +There is no entropy encoder backend nor framing layer -- the latter is +assumed to be handled by other parts of the system. + +This document only describes the format, not how the Snappy compressor nor +decompressor actually works. The correctness of the decompressor should not +depend on implementation details of the compressor, and vice versa. + + +1. Preamble + +The stream starts with the uncompressed length (up to a maximum of 2^32 - 1), +stored as a little-endian varint. Varints consist of a series of bytes, +where the lower 7 bits are data and the upper bit is set iff there are +more bytes to be read. In other words, an uncompressed length of 64 would +be stored as 0x40, and an uncompressed length of 2097150 (0x1FFFFE) +would be stored as 0xFE 0xFF 0x7F. + + +2. The compressed stream itself + +There are two types of elements in a Snappy stream: Literals and +copies (backreferences). There is no restriction on the order of elements, +except that the stream naturally cannot start with a copy. (Having +two literals in a row is never optimal from a compression point of +view, but nevertheless fully permitted.) Each element starts with a tag byte, +and the lower two bits of this tag byte signal what type of element will +follow: + + 00: Literal + 01: Copy with 1-byte offset + 10: Copy with 2-byte offset + 11: Copy with 4-byte offset + +The interpretation of the upper six bits are element-dependent. + + +2.1. Literals (00) + +Literals are uncompressed data stored directly in the byte stream. +The literal length is stored differently depending on the length +of the literal: + + - For literals up to and including 60 bytes in length, the upper + six bits of the tag byte contain (len-1). The literal follows + immediately thereafter in the bytestream. + - For longer literals, the (len-1) value is stored after the tag byte, + little-endian. The upper six bits of the tag byte describe how + many bytes are used for the length; 60, 61, 62 or 63 for + 1-4 bytes, respectively. The literal itself follows after the + length. + + +2.2. Copies + +Copies are references back into previous decompressed data, telling +the decompressor to reuse data it has previously decoded. +They encode two values: The _offset_, saying how many bytes back +from the current position to read, and the _length_, how many bytes +to copy. Offsets of zero can be encoded, but are not legal; +similarly, it is possible to encode backreferences that would +go past the end of the block (offset > current decompressed position), +which is also nonsensical and thus not allowed. + +As in most LZ77-based compressors, the length can be larger than the offset, +yielding a form of run-length encoding (RLE). For instance, +"xababab" could be encoded as + + + +Note that since the current Snappy compressor works in 32 kB +blocks and does not do matching across blocks, it will never produce +a bitstream with offsets larger than about 32768. However, the +decompressor should not rely on this, as it may change in the future. + +There are several different kinds of copy elements, depending on +the amount of bytes to be copied (length), and how far back the +data to be copied is (offset). + + +2.2.1.

It also provides data checksums to +help verify integrity. It does not provide metadata checksums, so it does +not protect against e.g. all forms of truncations. + +Implementation of the framing format is optional for Snappy compressors and +decompressor; it is not part of the Snappy core specification. + + +1. General structure + +The file consists solely of chunks, lying back-to-back with no padding +in between. Each chunk consists first a single byte of chunk identifier, +then a three-byte little-endian length of the chunk in bytes (from 0 to +16777215, inclusive), and then the data if any. The four bytes of chunk +header is not counted in the data length. + +The different chunk types are listed below. The first chunk must always +be the stream identifier chunk (see section 4.1, below). The stream +ends when the file ends -- there is no explicit end-of-file marker. + + +2. File type identification + +The following identifiers for this format are recommended where appropriate. +However, note that none have been registered officially, so this is only to +be taken as a guideline. We use "Snappy framed" to distinguish between this +format and raw Snappy data. + + File extension: .sz + MIME type: application/x-snappy-framed + HTTP Content-Encoding: x-snappy-framed + + +3. Checksum format + +Some chunks have data protected by a checksum (the ones that do will say so +explicitly). The checksums are always masked CRC-32Cs. + +A description of CRC-32C can be found in RFC 3720, section 12.1, with +examples in section B.4. + +Checksums are not stored directly, but masked, as checksumming data and +then its own checksum can be problematic. The masking is the same as used +in Apache Hadoop: Rotate the checksum by 15 bits, then add the constant +0xa282ead8 (using wraparound as normal for unsigned integers). This is +equivalent to the following C code: + + uint32_t mask_checksum(uint32_t x) { + return ((x >> 15) | (x << 17)) + 0xa282ead8; + } + +Note that the masking is reversible. + +The checksum is always stored as a four bytes long integer, in little-endian. + + +4. Chunk types + +The currently supported chunk types are described below. The list may +be extended in the future. + + +4.1. Stream identifier (chunk type 0xff) + +The stream identifier is always the first element in the stream. +It is exactly six bytes long and contains "sNaPpY" in ASCII. This means that +a valid Snappy framed stream always starts with the bytes + + 0xff 0x06 0x00 0x00 0x73 0x4e 0x61 0x50 0x70 0x59 + +The stream identifier chunk can come multiple times in the stream besides +the first; if such a chunk shows up, it should simply be ignored, assuming +it has the right length and contents. This allows for easy concatenation of +compressed files without the need for re-framing. + + +4.2. Compressed data (chunk type 0x00) + +Compressed data chunks contain a normal Snappy compressed bitstream; +see the compressed format specification. The compressed data is preceded by +the CRC-32C (see section 3) of the _uncompressed_ data. + +Note that the data portion of the chunk, i.e., the compressed contents, +can be at most 16777211 bytes (2^24 - 1, minus the checksum). +However, we place an additional restriction that the uncompressed data +in a chunk must be no longer than 65536 bytes. This allows consumers to +easily use small fixed-size buffers. + + +4.3. Uncompressed data (chunk type 0x01) + +Uncompressed data chunks allow a compressor to send uncompressed, +raw data; this is useful if, for instance, uncompressible or +near-incompressible data is detected, and faster decompression is desired. + +As in the compressed chunks, the data is preceded by its own masked +CRC-32C (see section 3). + +An uncompressed data chunk, like compressed data chunks, should contain +no more than 65536 data bytes, so the maximum legal chunk length with the +checksum is 65540. + + +4.4. Reserved unskippable chunks (chunk types 0x02-0x7f) + +These are reserved for future expansion. A decoder that sees such a chunk +should immediately return an error, as it must assume it cannot decode the +stream correctly. + +Future versions of this specification may define meanings for these chunks. + + +4.5. Reserved skippable chunks (chunk types 0x80-0xfe) + +These are also reserved for future expansion, but unlike the chunks +described in 4.4, a decoder seeing these must skip them and continue +decoding. + +Future versions of this specification may define meanings for these chunks. diff --git a/chromium/third_party/snappy/src/m4/gtest.m4 b/chromium/third_party/snappy/src/m4/gtest.m4 new file mode 100644 index 00000000000..98e61f9624b --- /dev/null +++ b/chromium/third_party/snappy/src/m4/gtest.m4 @@ -0,0 +1,74 @@ +dnl GTEST_LIB_CHECK([minimum version [, +dnl action if found [,action if not found]]]) +dnl +dnl Check for the presence of the Google Test library, optionally at a minimum +dnl version, and indicate a viable version with the HAVE_GTEST flag.

nor did Alice +think it so VERY much out of the way to hear the Rabbit say to +itself, `Oh dear! Oh dear! I shall be late!' (when she thought +it over afterwards, it occurred to her that she ought to have +wondered at this, but at the time it all seemed quite natural); +but when the Rabbit actually TOOK A WATCH OUT OF ITS WAISTCOAT- +POCKET, and looked at it, and then hurried on, Alice started to +her feet, for it flashed across her mind that she had never +before seen a rabbit with either a waistcoat-pocket, or a watch to +take out of it, and burning with curiosity, she ran across the +field after it, and fortunately was just in time to see it pop +down a large rabbit-hole under the hedge. + + In another moment down went Alice after it, never once +considering how in the world she was to get out again. + + The rabbit-hole went straight on like a tunnel for some way, +and then dipped suddenly down, so suddenly that Alice had not a +moment to think about stopping herself before she found herself +falling down a very deep well. + + Either the well was very deep, or she fell very slowly, for she +had plenty of time as she went down to look about her and to +wonder what was going to happen next. First, she tried to look +down and make out what she was coming to, but it was too dark to +see anything; then she looked at the sides of the well, and +noticed that they were filled with cupboards and book-shelves; +here and there she saw maps and pictures hung upon pegs. She +took down a jar from one of the shelves as she passed; it was +labelled `ORANGE MARMALADE', but to her great disappointment it +was empty: she did not like to drop the jar for fear of killing +somebody, so managed to put it into one of the cupboards as she +fell past it. + + `Well!' thought Alice to herself, `after such a fall as this, I +shall think nothing of tumbling down stairs! How brave they'll +all think me at home! Why, I wouldn't say anything about it, +even if I fell off the top of the house!' (Which was very likely +true.) + + Down, down, down. Would the fall NEVER come to an end! `I +wonder how many miles I've fallen by this time?' she said aloud. +`I must be getting somewhere near the centre of the earth. Let +me see: that would be four thousand miles down, I think--' (for, +you see, Alice had learnt several things of this sort in her +lessons in the schoolroom, and though this was not a VERY good +opportunity for showing off her knowledge, as there was no one to +listen to her, still it was good practice to say it over) `--yes, +that's about the right distance--but then I wonder what Latitude +or Longitude I've got to?' (Alice had no idea what Latitude was, +or Longitude either, but thought they were nice grand words to +say.) + + Presently she began again. `I wonder if I shall fall right +THROUGH the earth! How funny it'll seem to come out among the +people that walk with their heads downward! The Antipathies, I +think--' (she was rather glad there WAS no one listening, this +time, as it didn't sound at all the right word) `--but I shall +have to ask them what the name of the country is, you know. +Please, Ma'am, is this New Zealand or Australia?' (and she tried +to curtsey as she spoke--fancy CURTSEYING as you're falling +through the air! Do you think you could manage it?) `And what +an ignorant little girl she'll think me for asking! No, it'll +never do to ask: perhaps I shall see it written up somewhere.' + + Down, down, down. There was nothing else to do, so Alice soon +began talking again. `Dinah'll miss me very much to-night, I +should think!' (Dinah was the cat.) `I hope they'll remember +her saucer of milk at tea-time. Dinah my dear! I wish you were +down here with me! There are no mice in the air, I'm afraid, but +you might catch a bat, and that's very like a mouse, you know. +But do cats eat bats, I wonder?' And here Alice began to get +rather sleepy, and went on saying to herself, in a dreamy sort of +way, `Do cats eat bats? Do cats eat bats?' and sometimes, `Do +bats eat cats?' for, you see, as she couldn't answer either +question, it didn't much matter which way she put it. She felt +that she was dozing off, and had just begun to dream that she +was walking hand in hand with Dinah, and saying to her very +earnestly, `Now, Dinah, tell me the truth: did you ever eat a +bat?' when suddenly, thump! thump! down she came upon a heap of +sticks and dry leaves, and the fall was over. + + Alice was not a bit hurt, and she jumped up on to her feet in a +moment: she looked up, but it was all dark overhead; before her +was another long passage, and the White Rabbit was still in +sight, hurrying down it. There was not a moment to be lost: +away went Alice like the wind, and was just in time to hear it +say, as it turned a corner, `Oh my ears and whiskers, how late +it's getting!' She was close behind it when she turned the +corner, but the Rabbit was no longer to be seen: she found +herself in a long, low hall, which was lit up by a row of lamps +hanging from the roof. + + There were doors all round the hall, but they were all locked; +and when Alice had been all the way down one side and up the +other, trying every door, she walked sadly down the middle, +wondering how she was ever to get out again. + + Suddenly she came upon a little three-legged table, all made of +solid glass; there was nothing on it except a tiny golden key, +and Alice's first thought was that it might belong to one of the +doors of the hall; but, alas! either the locks were too large, or +the key was too small, but at any rate it would not open any of +them. However, on the second time round, she came upon a low +curtain she had not noticed before, and behind it was a little +door about fifteen inches high: she tried the little golden key +in the lock, and to her great delight it fitted! + + Alice opened the door and found that it led into a small +passage, not much larger than a rat-hole: she knelt down and +looked along the passage into the loveliest garden you ever saw. +How she longed to get out of that dark hall, and wander about +among those beds of bright flowers and those cool fountains, but +she could not even get her head though the doorway; `and even if +my head would go through,' thought poor Alice, `it would be of +very little use without my shoulders. Oh, how I wish +I could shut up like a telescope! I think I could, if I only +know how to begin.' For, you see, so many out-of-the-way things +had happened lately, that Alice had begun to think that very few +things indeed were really impossible. + + There seemed to be no use in waiting by the little door, so she +went back to the table, half hoping she might find another key on +it, or at any rate a book of rules for shutting people up like +telescopes: this time she found a little bottle on it, (`which +certainly was not here before,' said Alice,) and round the neck +of the bottle was a paper label, with the words `DRINK ME' +beautifully printed on it in large letters. + + It was all very well to say `Drink me,' but the wise little +Alice was not going to do THAT in a hurry. `No, I'll look +first,' she said, `and see whether it's marked "poison" or not'; +for she had read several nice little histories about children who +had got burnt, and eaten up by wild beasts and other unpleasant +things, all because they WOULD not remember the simple rules +their friends had taught them: such as, that a red-hot poker +will burn you if you hold it too long; and that if you cut your +finger VERY deeply with a knife, it usually bleeds; and she had +never forgotten that, if you drink much from a bottle marked +`poison,' it is almost certain to disagree with you, sooner or +later. + + However, this bottle was NOT marked `poison,' so Alice ventured +to taste it, and finding it very nice, (it had, in fact, a sort +of mixed flavour of cherry-tart, custard, pine-apple, roast +turkey, toffee, and hot buttered toast,) she very soon finished +it off. + + * * * * * * * + + * * * * * * + + * * * * * * * + + `What a curious feeling!' said Alice; `I must be shutting up +like a telescope.' + + And so it was indeed: she was now only ten inches high, and +her face brightened up at the thought that she was now the right +size for going though the little door into that lovely garden. +First, however, she waited for a few minutes to see if she was +going to shrink any further: she felt a little nervous about +this; `for it might end, you know,' said Alice to herself, `in my +going out altogether, like a candle. I wonder what I should be +like then?' And she tried to fancy what the flame of a candle is +like after the candle is blown out, for she could not remember +ever having seen such a thing. + + After a while, finding that nothing more happened, she decided +on going into the garden at once; but, alas for poor Alice! when +she got to the door, she found he had forgotten the little golden +key, and when she went back to the table for it, she found she +could not possibly reach it: she could see it quite plainly +through the glass, and she tried her best to climb up one of the +legs of the table, but it was too slippery; and when she had +tired herself out with trying, the poor little thing sat down and +cried. + + `Come, there's no use in crying like that!' said Alice to +herself, rather sharply; `I advise you to leave off this minute!' +She generally gave herself very good advice, (though she very +seldom followed it), and sometimes she scolded herself so +severely as to bring tears into her eyes; and once she remembered +trying to box her own ears for having cheated herself in a game +of croquet she was playing against herself, for this curious +child was very fond of pretending to be two people. `But it's no +use now,' thought poor Alice, `to pretend to be two people! Why, +there's hardly enough of me left to make ONE respectable +person!' + + Soon her eye fell on a little glass box that was lying under +the table: she opened it, and found in it a very small cake, on +which the words `EAT ME' were beautifully marked in currants. +`Well, I'll eat it,' said Alice, `and if it makes me grow larger, +I can reach the key; and if it makes me grow smaller, I can creep +under the door; so either way I'll get into the garden, and I +don't care which happens!' + + She ate a little bit, and said anxiously to herself, `Which +way? Which way?', holding her hand on the top of her head to +feel which way it was growing, and she was quite surprised to +find that she remained the same size: to be sure, this generally +happens when one eats cake, but Alice had got so much into the +way of expecting nothing but out-of-the-way things to happen, +that it seemed quite dull and stupid for life to go on in the +common way. + + So she set to work, and very soon finished off the cake. + + * * * * * * * + + * * * * * * + + * * * * * * * + + + + + CHAPTER II + + The Pool of Tears + + + `Curiouser and curiouser!' cried Alice (she was so much +surprised, that for the moment she quite forgot how to speak good +English); `now I'm opening out like the largest telescope that +ever was! Good-bye, feet!' (for when she looked down at her +feet, they seemed to be almost out of sight, they were getting so +far off). `Oh, my poor little feet, I wonder who will put on +your shoes and stockings for you now, dears? I'm sure _I_ shan't +be able! I shall be a great deal too far off to trouble myself +about you: you must manage the best way you can; --but I must be +kind to them,' thought Alice, `or perhaps they won't walk the +way I want to go! Let me see: I'll give them a new pair of +boots every Christmas.' + + And she went on planning to herself how she would manage it. +`They must go by the carrier,' she thought; `and how funny it'll +seem, sending presents to one's own feet! And how odd the +directions will look! + + ALICE'S RIGHT FOOT, ESQ. + HEARTHRUG, + NEAR THE FENDER, + (WITH ALICE'S LOVE). + +Oh dear, what nonsense I'm talking!' + + Just then her head struck against the roof of the hall: in +fact she was now more than nine feet high, and she at once took +up the little golden key and hurried off to the garden door. + + Poor Alice! It was as much as she could do, lying down on one +side, to look through into the garden with one eye; but to get +through was more hopeless than ever: she sat down and began to +cry again. + + `You ought to be ashamed of yourself,' said Alice, `a great +girl like you,' (she might well say this), `to go on crying in +this way! Stop this moment, I tell you!' But she went on all +the same, shedding gallons of tears, until there was a large pool +all round her, about four inches deep and reaching half down the +hall. + + After a time she heard a little pattering of feet in the +distance, and she hastily dried her eyes to see what was coming. +It was the White Rabbit returning, splendidly dressed, with a +pair of white kid gloves in one hand and a large fan in the +other: he came trotting along in a great hurry, muttering to +himself as he came, `Oh! the Duchess, the Duchess! Oh! won't she +be savage if I've kept her waiting!' Alice felt so desperate +that she was ready to ask help of any one; so, when the Rabbit +came near her, she began, in a low, timid voice, `If you please, +sir--' The Rabbit started violently, dropped the white kid +gloves and the fan, and skurried away into the darkness as hard +as he could go. + + Alice took up the fan and gloves, and, as the hall was very +hot, she kept fanning herself all the time she went on talking: +`Dear, dear! How queer everything is to-day! And yesterday +things went on just as usual. I wonder if I've been changed in +the night? Let me think: was I the same when I got up this +morning? I almost think I can remember feeling a little +different. But if I'm not the same, the next question is, Who in +the world am I? Ah, THAT'S the great puzzle!' And she began +thinking over all the children she knew that were of the same age +as herself, to see if she could have been changed for any of +them. + + `I'm sure I'm not Ada,' she said, `for her hair goes in such +long ringlets, and mine doesn't go in ringlets at all; and I'm +sure I can't be Mabel, for I know all sorts of things, and she, +oh! she knows such a very little! Besides, SHE'S she, and I'm I, +and--oh dear, how puzzling it all is! I'll try if I know all the +things I used to know. Let me see: four times five is twelve, +and four times six is thirteen, and four times seven is--oh dear! +I shall never get to twenty at that rate! However, the +Multiplication Table doesn't signify: let's try Geography. +London is the capital of Paris, and Paris is the capital of Rome, +and Rome--no, THAT'S all wrong, I'm certain! I must have been +changed for Mabel! I'll try and say "How doth the little--"' +and she crossed her hands on her lap as if she were saying lessons, +and began to repeat it, but her voice sounded hoarse and +strange, and the words did not come the same as they used to do:-- + + `How doth the little crocodile + Improve his shining tail, + And pour the waters of the Nile + On every golden scale! + + `How cheerfully he seems to grin, + How neatly spread his claws, + And welcome little fishes in + With gently smiling jaws!' + + `I'm sure those are not the right words,' said poor Alice, and +her eyes filled with tears again as she went on, `I must be Mabel +after all, and I shall have to go and live in that poky little +house, and have next to no toys to play with, and oh! ever so +many lessons to learn! No, I've made up my mind about it; if I'm +Mabel, I'll stay down here! It'll be no use their putting their +heads down and saying "Come up again, dear!" I shall only look +up and say "Who am I then? Tell me that first, and then, if I +like being that person, I'll come up: if not, I'll stay down +here till I'm somebody else"--but, oh dear!' cried Alice, with a +sudden burst of tears, `I do wish they WOULD put their heads +down! I am so VERY tired of being all alone here!' + + As she said this she looked down at her hands, and was +surprised to see that she had put on one of the Rabbit's little +white kid gloves while she was talking. `How CAN I have done +that?' she thought. `I must be growing small again.' She got up +and went to the table to measure herself by it, and found that, +as nearly as she could guess, she was now about two feet high, +and was going on shrinking rapidly: she soon found out that the +cause of this was the fan she was holding, and she dropped it +hastily, just in time to avoid shrinking away altogether. + +`That WAS a narrow escape!' said Alice, a good deal frightened at +the sudden change, but very glad to find herself still in +existence; `and now for the garden!' and she ran with all speed +back to the little door: but, alas! the little door was shut +again, and the little golden key was lying on the glass table as +before, `and things are worse than ever,' thought the poor child, +`for I never was so small as this before, never! And I declare +it's too bad, that it is!' + + As she said these words her foot slipped, and in another +moment, splash! she was up to her chin in salt water. He first +idea was that she had somehow fallen into the sea, `and in that +case I can go back by railway,' she said to herself. (Alice had +been to the seaside once in her life, and had come to the general +conclusion, that wherever you go to on the English coast you find +a number of bathing machines in the sea, some children digging in +the sand with wooden spades, then a row of lodging houses, and +behind them a railway station.) However, she soon made out that +she was in the pool of tears which she had wept when she was nine +feet high. + + `I wish I hadn't cried so much!' said Alice, as she swam about, +trying to find her way out. `I shall be punished for it now, I +suppose, by being drowned in my own tears! That WILL be a queer +thing, to be sure! However, everything is queer to-day.' + + Just then she heard something splashing about in the pool a +little way off, and she swam nearer to make out what it was: at +first she thought it must be a walrus or hippopotamus, but then +she remembered how small she was now, and she soon made out that +it was only a mouse that had slipped in like herself. + + `Would it be of any use, now,' thought Alice, `to speak to this +mouse? Everything is so out-of-the-way down here, that I should +think very likely it can talk: at any rate, there's no harm in +trying.' So she began: `O Mouse, do you know the way out of +this pool? I am very tired of swimming about here, O Mouse!' +(Alice thought this must be the right way of speaking to a mouse: +she had never done such a thing before, but she remembered having +seen in her brother's Latin Grammar, `A mouse--of a mouse--to a +mouse--a mouse--O mouse!' The Mouse looked at her rather +inquisitively, and seemed to her to wink with one of its little +eyes, but it said nothing. + + `Perhaps it doesn't understand English,' thought Alice; `I +daresay it's a French mouse, come over with William the +Conqueror.' (For, with all her knowledge of history, Alice had +no very clear notion how long ago anything had happened.) So she +began again: `Ou est ma chatte?' which was the first sentence in +her French lesson-book. The Mouse gave a sudden leap out of the +water, and seemed to quiver all over with fright. `Oh, I beg +your pardon!' cried Alice hastily, afraid that she had hurt the +poor animal's feelings. `I quite forgot you didn't like cats.' + + `Not like cats!' cried the Mouse, in a shrill, passionate +voice. `Would YOU like cats if you were me?' + + `Well, perhaps not,' said Alice in a soothing tone: `don't be +angry about it. And yet I wish I could show you our cat Dinah: +I think you'd take a fancy to cats if you could only see her. +She is such a dear quiet thing,' Alice went on, half to herself, +as she swam lazily about in the pool, `and she sits purring so +nicely by the fire, licking her paws and washing her face--and +she is such a nice soft thing to nurse--and she's such a capital +one for catching mice--oh, I beg your pardon!' cried Alice again, +for this time the Mouse was bristling all over, and she felt +certain it must be really offended. `We won't talk about her any +more if you'd rather not.' + + `We indeed!' cried the Mouse, who was trembling down to the end +of his tail. `As if I would talk on such a subject! Our family +always HATED cats: nasty, low, vulgar things! Don't let me hear +the name again!' + + `I won't indeed!' said Alice, in a great hurry to change the +subject of conversation. `Are you--are you fond--of--of dogs?' +The Mouse did not answer, so Alice went on eagerly: `There is +such a nice little dog near our house I should like to show you! +A little bright-eyed terrier, you know, with oh, such long curly +brown hair! And it'll fetch things when you throw them, and +it'll sit up and beg for its dinner, and all sorts of things--I +can't remember half of them--and it belongs to a farmer, you +know, and he says it's so useful, it's worth a hundred pounds! +He says it kills all the rats and--oh dear!' cried Alice in a +sorrowful tone, `I'm afraid I've offended it again!' For the +Mouse was swimming away from her as hard as it could go, and +making quite a commotion in the pool as it went. + + So she called softly after it, `Mouse dear! Do come back +again, and we won't talk about cats or dogs either, if you don't +like them!' When the Mouse heard this, it turned round and swam +slowly back to her: its face was quite pale (with passion, Alice +thought), and it said in a low trembling voice, `Let us get to +the shore, and then I'll tell you my history, and you'll +understand why it is I hate cats and dogs.' + + It was high time to go, for the pool was getting quite crowded +with the birds and animals that had fallen into it: there were a +Duck and a Dodo, a Lory and an Eaglet, and several other curious +creatures. Alice led the way, and the whole party swam to the +shore. + + + + CHAPTER III + + A Caucus-Race and a Long Tale + + + They were indeed a queer-looking party that assembled on the +bank--the birds with draggled feathers, the animals with their +fur clinging close to them, and all dripping wet, cross, and +uncomfortable. + + The first question of course was, how to get dry again: they +had a consultation about this, and after a few minutes it seemed +quite natural to Alice to find herself talking familiarly with +them, as if she had known them all her life. Indeed, she had +quite a long argument with the Lory, who at last turned sulky, +and would only say, `I am older than you, and must know better'; +and this Alice would not allow without knowing how old it was, +and, as the Lory positively refused to tell its age, there was no +more to be said. + + At last the Mouse, who seemed to be a person of authority among +them, called out, `Sit down, all of you, and listen to me! I'LL +soon make you dry enough!' They all sat down at once, in a large +ring, with the Mouse in the middle. Alice kept her eyes +anxiously fixed on it, for she felt sure she would catch a bad +cold if she did not get dry very soon. + + `Ahem!' said the Mouse with an important air, `are you all ready? +This is the driest thing I know. Silence all round, if you please! +"William the Conqueror, whose cause was favoured by the pope, was +soon submitted to by the English, who wanted leaders, and had been +of late much accustomed to usurpation and conquest. Edwin and +Morcar, the earls of Mercia and Northumbria--"' + + `Ugh!' said the Lory, with a shiver. + + `I beg your pardon!' said the Mouse, frowning, but very +politely: `Did you speak?' + + `Not I!' said the Lory hastily. + + `I thought you did,' said the Mouse. `--I proceed. "Edwin and +Morcar, the earls of Mercia and Northumbria, declared for him: +and even Stigand, the patriotic archbishop of Canterbury, found +it advisable--"' + + `Found WHAT?' said the Duck. + + `Found IT,' the Mouse replied rather crossly: `of course you +know what "it" means.' + + `I know what "it" means well enough, when I find a thing,' said +the Duck: `it's generally a frog or a worm. The question is, +what did the archbishop find?' + + The Mouse did not notice this question, but hurriedly went on, +`"--found it advisable to go with Edgar Atheling to meet William +and offer him the crown. William's conduct at first was +moderate. But the insolence of his Normans--" How are you +getting on now, my dear?' it continued, turning to Alice as it +spoke. + + `As wet as ever,' said Alice in a melancholy tone: `it doesn't +seem to dry me at all.' + + `In that case,' said the Dodo solemnly, rising to its feet, `I +move that the meeting adjourn, for the immediate adoption of more +energetic remedies--' + + `Speak English!' said the Eaglet. `I don't know the meaning of +half those long words, and, what's more, I don't believe you do +either!' And the Eaglet bent down its head to hide a smile: +some of the other birds tittered audibly. + + `What I was going to say,' said the Dodo in an offended tone, +`was, that the best thing to get us dry would be a Caucus-race.' + + `What IS a Caucus-race?' said Alice; not that she wanted much +to know, but the Dodo had paused as if it thought that SOMEBODY +ought to speak, and no one else seemed inclined to say anything. + + `Why,' said the Dodo, `the best way to explain it is to do it.' +(And, as you might like to try the thing yourself, some winter +day, I will tell you how the Dodo managed it.) + + First it marked out a race-course, in a sort of circle, (`the +exact shape doesn't matter,' it said,) and then all the party +were placed along the course, here and there. There was no `One, +two, three, and away,' but they began running when they liked, +and left off when they liked, so that it was not easy to know +when the race was over. However, when they had been running half +an hour or so, and were quite dry again, the Dodo suddenly called +out `The race is over!' and they all crowded round it, panting, +and asking, `But who has won?' + + This question the Dodo could not answer without a great deal of +thought, and it sat for a long time with one finger pressed upon +its forehead (the position in which you usually see Shakespeare, +in the pictures of him), while the rest waited in silence. At +last the Dodo said, `EVERYBODY has won, and all must have +prizes.' + + `But who is to give the prizes?' quite a chorus of voices +asked. + + `Why, SHE, of course,' said the Dodo, pointing to Alice with +one finger; and the whole party at once crowded round her, +calling out in a confused way, `Prizes! Prizes!' + + Alice had no idea what to do, and in despair she put her hand +in her pocket, and pulled out a box of comfits, (luckily the salt +water had not got into it), and handed them round as prizes. +There was exactly one a-piece all round. + + `But she must have a prize herself, you know,' said the Mouse. + + `Of course,' the Dodo replied very gravely. `What else have +you got in your pocket?' he went on, turning to Alice. + + `Only a thimble,' said Alice sadly. + + `Hand it over here,' said the Dodo. + + Then they all crowded round her once more, while the Dodo +solemnly presented the thimble, saying `We beg your acceptance of +this elegant thimble'; and, when it had finished this short +speech, they all cheered. + + Alice thought the whole thing very absurd, but they all looked +so grave that she did not dare to laugh; and, as she could not +think of anything to say, she simply bowed, and took the thimble, +looking as solemn as she could. + + The next thing was to eat the comfits: this caused some noise +and confusion, as the large birds complained that they could not +taste theirs, and the small ones choked and had to be patted on +the back. However, it was over at last, and they sat down again +in a ring, and begged the Mouse to tell them something more. + + `You promised to tell me your history, you know,' said Alice, +`and why it is you hate--C and D,' she added in a whisper, half +afraid that it would be offended again. + + `Mine is a long and a sad tale!' said the Mouse, turning to +Alice, and sighing. + + `It IS a long tail, certainly,' said Alice, looking down with +wonder at the Mouse's tail; `but why do you call it sad?' And +she kept on puzzling about it while the Mouse was speaking, so +that her idea of the tale was something like this:-- + + `Fury said to a + mouse, That he + met in the + house, + "Let us + both go to + law: I will + prosecute + YOU. --Come, + I'll take no + denial; We + must have a + trial: For + really this + morning I've + nothing + to do." + Said the + mouse to the + cur, "Such + a trial, + dear Sir, + With + no jury + or judge, + would be + wasting + our + breath." + "I'll be + judge, I'll + be jury," + Said + cunning + old Fury: + "I'll + try the + whole + cause, + and + condemn + you + to + death."' + + + `You are not attending!' said the Mouse to Alice severely. +`What are you thinking of?' + + `I beg your pardon,' said Alice very humbly: `you had got to +the fifth bend, I think?' + + `I had NOT!' cried the Mouse, sharply and very angrily. + + `A knot!' said Alice, always ready to make herself useful, and +looking anxiously about her. `Oh, do let me help to undo it!' + + `I shall do nothing of the sort,' said the Mouse, getting up +and walking away. `You insult me by talking such nonsense!' + + `I didn't mean it!' pleaded poor Alice. `But you're so easily +offended, you know!' + + The Mouse only growled in reply. + + `Please come back and finish your story!' Alice called after +it; and the others all joined in chorus, `Yes, please do!' but +the Mouse only shook its head impatiently, and walked a little +quicker. + + `What a pity it wouldn't stay!' sighed the Lory, as soon as it +was quite out of sight; and an old Crab took the opportunity of +saying to her daughter `Ah, my dear! Let this be a lesson to you +never to lose YOUR temper!' `Hold your tongue, Ma!' said the +young Crab, a little snappishly. `You're enough to try the +patience of an oyster!' + + `I wish I had our Dinah here, I know I do!' said Alice aloud, +addressing nobody in particular. `She'd soon fetch it back!' + + `And who is Dinah, if I might venture to ask the question?' +said the Lory. + + Alice replied eagerly, for she was always ready to talk about +her pet: `Dinah's our cat. And she's such a capital one for +catching mice you can't think! And oh, I wish you could see her +after the birds! Why, she'll eat a little bird as soon as look +at it!' + + This speech caused a remarkable sensation among the party. +Some of the birds hurried off at once: one the old Magpie began +wrapping itself up very carefully, remarking, `I really must be +getting home; the night-air doesn't suit my throat!' and a Canary +called out in a trembling voice to its children, `Come away, my +dears! It's high time you were all in bed!' On various pretexts +they all moved off, and Alice was soon left alone. + + `I wish I hadn't mentioned Dinah!' she said to herself in a +melancholy tone. `Nobody seems to like her, down here, and I'm +sure she's the best cat in the world! Oh, my dear Dinah! I +wonder if I shall ever see you any more!' And here poor Alice +began to cry again, for she felt very lonely and low-spirited. +In a little while, however, she again heard a little pattering of +footsteps in the distance, and she looked up eagerly, half hoping +that the Mouse had changed his mind, and was coming back to +finish his story. + + + + CHAPTER IV + + The Rabbit Sends in a Little Bill + + + It was the White Rabbit, trotting slowly back again, and +looking anxiously about as it went, as if it had lost something; +and she heard it muttering to itself `The Duchess! The Duchess! +Oh my dear paws! Oh my fur and whiskers! She'll get me +executed, as sure as ferrets are ferrets! Where CAN I have +dropped them, I wonder?' Alice guessed in a moment that it was +looking for the fan and the pair of white kid gloves, and she +very good-naturedly began hunting about for them, but they were +nowhere to be seen--everything seemed to have changed since her +swim in the pool, and the great hall, with the glass table and +the little door, had vanished completely. + + Very soon the Rabbit noticed Alice, as she went hunting about, +and called out to her in an angry tone, `Why, Mary Ann, what ARE +you doing out here? Run home this moment, and fetch me a pair of +gloves and a fan! Quick, now!' And Alice was so much frightened +that she ran off at once in the direction it pointed to, without +trying to explain the mistake it had made. + + `He took me for his housemaid,' she said to herself as she ran. +`How surprised he'll be when he finds out who I am! But I'd +better take him his fan and gloves--that is, if I can find them.' +As she said this, she came upon a neat little house, on the door +of which was a bright brass plate with the name `W. RABBIT' +engraved upon it. She went in without knocking, and hurried +upstairs, in great fear lest she should meet the real Mary Ann, +and be turned out of the house before she had found the fan and +gloves. + + `How queer it seems,' Alice said to herself, `to be going +messages for a rabbit! I suppose Dinah'll be sending me on +messages next!' And she began fancying the sort of thing that +would happen: `"Miss Alice! Come here directly, and get ready +for your walk!" "Coming in a minute, nurse! But I've got to see +that the mouse doesn't get out." Only I don't think,' Alice went +on, `that they'd let Dinah stop in the house if it began ordering +people about like that!' + + By this time she had found her way into a tidy little room with +a table in the window, and on it (as she had hoped) a fan and two +or three pairs of tiny white kid gloves: she took up the fan and +a pair of the gloves, and was just going to leave the room, when +her eye fell upon a little bottle that stood near the looking- +glass. There was no label this time with the words `DRINK ME,' +but nevertheless she uncorked it and put it to her lips. `I know +SOMETHING interesting is sure to happen,' she said to herself, +`whenever I eat or drink anything; so I'll just see what this +bottle does. I do hope it'll make me grow large again, for +really I'm quite tired of being such a tiny little thing!' + + It did so indeed, and much sooner than she had expected: +before she had drunk half the bottle, she found her head pressing +against the ceiling, and had to stoop to save her neck from being +broken. She hastily put down the bottle, saying to herself +`That's quite enough--I hope I shan't grow any more--As it is, I +can't get out at the door--I do wish I hadn't drunk quite so +much!' + + Alas! it was too late to wish that! She went on growing, and +growing, and very soon had to kneel down on the floor: in +another minute there was not even room for this, and she tried +the effect of lying down with one elbow against the door, and the +other arm curled round her head. Still she went on growing, and, +as a last resource, she put one arm out of the window, and one +foot up the chimney, and said to herself `Now I can do no more, +whatever happens. What WILL become of me?' + + Luckily for Alice, the little magic bottle had now had its full +effect, and she grew no larger: still it was very uncomfortable, +and, as there seemed to be no sort of chance of her ever getting +out of the room again, no wonder she felt unhappy. + + `It was much pleasanter at home,' thought poor Alice, `when one +wasn't always growing larger and smaller, and being ordered about +by mice and rabbits. I almost wish I hadn't gone down that +rabbit-hole--and yet--and yet--it's rather curious, you know, +this sort of life! I do wonder what CAN have happened to me! +When I used to read fairy-tales, I fancied that kind of thing +never happened, and now here I am in the middle of one! There +ought to be a book written about me, that there ought! And when +I grow up, I'll write one--but I'm grown up now,' she added in a +sorrowful tone; `at least there's no room to grow up any more +HERE.' + + `But then,' thought Alice, `shall I NEVER get any older than I +am now? That'll be a comfort, one way--never to be an old woman- +-but then--always to have lessons to learn! Oh, I shouldn't like +THAT!' + + `Oh, you foolish Alice!' she answered herself. `How can you +learn lessons in here? Why, there's hardly room for YOU, and no +room at all for any lesson-books!' + + And so she went on, taking first one side and then the other, +and making quite a conversation of it altogether; but after a few +minutes she heard a voice outside, and stopped to listen. + + `Mary Ann! Mary Ann!' said the voice. `Fetch me my gloves +this moment!' Then came a little pattering of feet on the +stairs. Alice knew it was the Rabbit coming to look for her, and +she trembled till she shook the house, quite forgetting that she +was now about a thousand times as large as the Rabbit, and had no +reason to be afraid of it. + + Presently the Rabbit came up to the door, and tried to open it; +but, as the door opened inwards, and Alice's elbow was pressed +hard against it, that attempt proved a failure. Alice heard it +say to itself `Then I'll go round and get in at the window.' + + `THAT you won't' thought Alice, and, after waiting till she +fancied she heard the Rabbit just under the window, she suddenly +spread out her hand, and made a snatch in the air. She did not +get hold of anything, but she heard a little shriek and a fall, +and a crash of broken glass, from which she concluded that it was +just possible it had fallen into a cucumber-frame, or something +of the sort. + + Next came an angry voice--the Rabbit's--`Pat! Pat! Where are +you?' And then a voice she had never heard before, `Sure then +I'm here! Digging for apples, yer honour!' + + `Digging for apples, indeed!' said the Rabbit angrily. `Here! +Come and help me out of THIS!' (Sounds of more broken glass.) + + `Now tell me, Pat, what's that in the window?' + + `Sure, it's an arm, yer honour!' (He pronounced it `arrum.') + + `An arm, you goose! Who ever saw one that size? Why, it +fills the whole window!' + + `Sure, it does, yer honour: but it's an arm for all that.' + + `Well, it's got no business there, at any rate: go and take it +away!' + + There was a long silence after this, and Alice could only hear +whispers now and then; such as, `Sure, I don't like it, yer +honour, at all, at all!' `Do as I tell you, you coward!' and at +last she spread out her hand again, and made another snatch in +the air. This time there were TWO little shrieks, and more +sounds of broken glass. `What a number of cucumber-frames there +must be!' thought Alice. `I wonder what they'll do next! As for +pulling me out of the window, I only wish they COULD! I'm sure I +don't want to stay in here any longer!' + + She waited for some time without hearing anything more: at +last came a rumbling of little cartwheels, and the sound of a +good many voice all talking together: she made out the words: +`Where's the other ladder?--Why, I hadn't to bring but one; +Bill's got the other--Bill! fetch it here, lad!--Here, put 'em up +at this corner--No, tie 'em together first--they don't reach half +high enough yet--Oh! they'll do well enough; don't be particular- +-Here, Bill! catch hold of this rope--Will the roof bear?--Mind +that loose slate--Oh, it's coming down! Heads below!' (a loud +crash)--`Now, who did that?--It was Bill, I fancy--Who's to go +down the chimney?--Nay, I shan't! YOU do it!--That I won't, +then!--Bill's to go down--Here, Bill! the master says you're to +go down the chimney!' + + `Oh! So Bill's got to come down the chimney, has he?' said +Alice to herself. `Shy, they seem to put everything upon Bill! +I wouldn't be in Bill's place for a good deal: this fireplace is +narrow, to be sure; but I THINK I can kick a little!' + + She drew her foot as far down the chimney as she could, and +waited till she heard a little animal (she couldn't guess of what +sort it was) scratching and scrambling about in the chimney close +above her: then, saying to herself `This is Bill,' she gave one +sharp kick, and waited to see what would happen next. + + The first thing she heard was a general chorus of `There goes +Bill!' then the Rabbit's voice along--`Catch him, you by the +hedge!' then silence, and then another confusion of voices--`Hold +up his head--Brandy now--Don't choke him--How was it, old fellow? +What happened to you? Tell us all about it!' + + Last came a little feeble, squeaking voice, (`That's Bill,' +thought Alice,) `Well, I hardly know--No more, thank ye; I'm +better now--but I'm a deal too flustered to tell you--all I know +is, something comes at me like a Jack-in-the-box, and up I goes +like a sky-rocket!' + + `So you did, old fellow!' said the others. + + `We must burn the house down!' said the Rabbit's voice; and +Alice called out as loud as she could, `If you do. I'll set +Dinah at you!' + + There was a dead silence instantly, and Alice thought to +herself, `I wonder what they WILL do next! If they had any +sense, they'd take the roof off.' After a minute or two, they +began moving about again, and Alice heard the Rabbit say, `A +barrowful will do, to begin with.' + + `A barrowful of WHAT?' thought Alice; but she had not long to +doubt, for the next moment a shower of little pebbles came +rattling in at the window, and some of them hit her in the face. +`I'll put a stop to this,' she said to herself, and shouted out, +`You'd better not do that again!' which produced another dead +silence. + + Alice noticed with some surprise that the pebbles were all +turning into little cakes as they lay on the floor, and a bright +idea came into her head. `If I eat one of these cakes,' she +thought, `it's sure to make SOME change in my size; and as it +can't possibly make me larger, it must make me smaller, I +suppose.' + + So she swallowed one of the cakes, and was delighted to find +that she began shrinking directly. As soon as she was small +enough to get through the door, she ran out of the house, and +found quite a crowd of little animals and birds waiting outside. +The poor little Lizard, Bill, was in the middle, being held up by +two guinea-pigs, who were giving it something out of a bottle. +They all made a rush at Alice the moment she appeared; but she +ran off as hard as she could, and soon found herself safe in a +thick wood. + + `The first thing I've got to do,' said Alice to herself, as she +wandered about in the wood, `is to grow to my right size again; +and the second thing is to find my way into that lovely garden. +I think that will be the best plan.' + + It sounded an excellent plan, no doubt, and very neatly and +simply arranged; the only difficulty was, that she had not the +smallest idea how to set about it; and while she was peering +about anxiously among the trees, a little sharp bark just over +her head made her look up in a great hurry. + + An enormous puppy was looking down at her with large round +eyes, and feebly stretching out one paw, trying to touch her. +`Poor little thing!' said Alice, in a coaxing tone, and she tried +hard to whistle to it; but she was terribly frightened all the +time at the thought that it might be hungry, in which case it +would be very likely to eat her up in spite of all her coaxing. + + Hardly knowing what she did, she picked up a little bit of +stick, and held it out to the puppy; whereupon the puppy jumped +into the air off all its feet at once, with a yelp of delight, +and rushed at the stick, and made believe to worry it; then Alice +dodged behind a great thistle, to keep herself from being run +over; and the moment she appeared on the other side, the puppy +made another rush at the stick, and tumbled head over heels in +its hurry to get hold of it; then Alice, thinking it was very +like having a game of play with a cart-horse, and expecting every +moment to be trampled under its feet, ran round the thistle +again; then the puppy began a series of short charges at the +stick, running a very little way forwards each time and a long +way back, and barking hoarsely all the while, till at last it sat +down a good way off, panting, with its tongue hanging out of its +mouth, and its great eyes half shut. + + This seemed to Alice a good opportunity for making her escape; +so she set off at once, and ran till she was quite tired and out +of breath, and till the puppy's bark sounded quite faint in the +distance. + + `And yet what a dear little puppy it was!' said Alice, as she +leant against a buttercup to rest herself, and fanned herself +with one of the leaves: `I should have liked teaching it tricks +very much, if--if I'd only been the right size to do it! Oh +dear! I'd nearly forgotten that I've got to grow up again! Let +me see--how IS it to be managed? I suppose I ought to eat or +drink something or other; but the great question is, what?' + + The great question certainly was, what? Alice looked all round +her at the flowers and the blades of grass, but she did not see +anything that looked like the right thing to eat or drink under +the circumstances. There was a large mushroom growing near her, +about the same height as herself; and when she had looked under +it, and on both sides of it, and behind it, it occurred to her +that she might as well look and see what was on the top of it. + + She stretched herself up on tiptoe, and peeped over the edge of +the mushroom, and her eyes immediately met those of a large +caterpillar, that was sitting on the top with its arms folded, +quietly smoking a long hookah, and taking not the smallest notice +of her or of anything else. + + + + CHAPTER V + + Advice from a Caterpillar + + + The Caterpillar and Alice looked at each other for some time in +silence: at last the Caterpillar took the hookah out of its +mouth, and addressed her in a languid, sleepy voice. + + `Who are YOU?' said the Caterpillar. + + This was not an encouraging opening for a conversation. Alice +replied, rather shyly, `I--I hardly know, sir, just at present-- +at least I know who I WAS when I got up this morning, but I think +I must have been changed several times since then.' + + `What do you mean by that?' said the Caterpillar sternly. +`Explain yourself!' + + `I can't explain MYSELF, I'm afraid, sir' said Alice, `because +I'm not myself, you see.' + + `I don't see,' said the Caterpillar. + + `I'm afraid I can't put it more clearly,' Alice replied very +politely, `for I can't understand it myself to begin with; and +being so many different sizes in a day is very confusing.' + + `It isn't,' said the Caterpillar. + + `Well, perhaps you haven't found it so yet,' said Alice; `but +when you have to turn into a chrysalis--you will some day, you +know--and then after that into a butterfly, I should think you'll +feel it a little queer, won't you?' + + `Not a bit,' said the Caterpillar. + + `Well, perhaps your feelings may be different,' said Alice; +`all I know is, it would feel very queer to ME.' + + `You!' said the Caterpillar contemptuously. `Who are YOU?' + + Which brought them back again to the beginning of the +conversation. Alice felt a little irritated at the Caterpillar's +making such VERY short remarks, and she drew herself up and said, +very gravely, `I think, you ought to tell me who YOU are, first.' + + `Why?' said the Caterpillar. + + Here was another puzzling question; and as Alice could not +think of any good reason, and as the Caterpillar seemed to be in +a VERY unpleasant state of mind, she turned away. + + `Come back!' the Caterpillar called after her. `I've something +important to say!' + + This sounded promising, certainly: Alice turned and came back +again. + + `Keep your temper,' said the Caterpillar. + + `Is that all?' said Alice, swallowing down her anger as well as +she could. + + `No,' said the Caterpillar. + + Alice thought she might as well wait, as she had nothing else +to do, and perhaps after all it might tell her something worth +hearing. For some minutes it puffed away without speaking, but +at last it unfolded its arms, took the hookah out of its mouth +again, and said, `So you think you're changed, do you?' + + `I'm afraid I am, sir,' said Alice; `I can't remember things as +I used--and I don't keep the same size for ten minutes together!' + + `Can't remember WHAT things?' said the Caterpillar. + + `Well, I've tried to say "HOW DOTH THE LITTLE BUSY BEE," but it +all came different!' Alice replied in a very melancholy voice. + + `Repeat, "YOU ARE OLD, FATHER WILLIAM,"' said the Caterpillar. + + Alice folded her hands, and began:-- + + `You are old, Father William,' the young man said, + `And your hair has become very white; + And yet you incessantly stand on your head-- + Do you think, at your age, it is right?' + + `In my youth,' Father William replied to his son, + `I feared it might injure the brain; + But, now that I'm perfectly sure I have none, + Why, I do it again and again.' + + `You are old,' said the youth, `as I mentioned before, + And have grown most uncommonly fat; + Yet you turned a back-somersault in at the door-- + Pray, what is the reason of that?' + + `In my youth,' said the sage, as he shook his grey locks, + `I kept all my limbs very supple + By the use of this ointment--one shilling the box-- + Allow me to sell you a couple?' + + `You are old,' said the youth, `and your jaws are too weak + For anything tougher than suet; + Yet you finished the goose, with the bones and the beak-- + Pray how did you manage to do it?' + + `In my youth,' said his father, `I took to the law, + And argued each case with my wife; + And the muscular strength, which it gave to my jaw, + Has lasted the rest of my life.' + + `You are old,' said the youth, `one would hardly suppose + That your eye was as steady as ever; + Yet you balanced an eel on the end of your nose-- + What made you so awfully clever?' + + `I have answered three questions, and that is enough,' + Said his father; `don't give yourself airs! + Do you think I can listen all day to such stuff? + Be off, or I'll kick you down stairs!' + + + `That is not said right,' said the Caterpillar. + + `Not QUITE right, I'm afraid,' said Alice, timidly; `some of the +words have got altered.' + + `It is wrong from beginning to end,' said the Caterpillar +decidedly, and there was silence for some minutes. + + The Caterpillar was the first to speak. + + `What size do you want to be?' it asked. + + `Oh, I'm not particular as to size,' Alice hastily replied; +`only one doesn't like changing so often, you know.' + + `I DON'T know,' said the Caterpillar. + + Alice said nothing: she had never been so much contradicted in +her life before, and she felt that she was losing her temper. + + `Are you content now?' said the Caterpillar. + + `Well, I should like to be a LITTLE larger, sir, if you +wouldn't mind,' said Alice: `three inches is such a wretched +height to be.' + + `It is a very good height indeed!' said the Caterpillar +angrily, rearing itself upright as it spoke (it was exactly three +inches high). + + `But I'm not used to it!' pleaded poor Alice in a piteous tone. +And she thought of herself, `I wish the creatures wouldn't be so +easily offended!' + + `You'll get used to it in time,' said the Caterpillar; and it +put the hookah into its mouth and began smoking again. + + This time Alice waited patiently until it chose to speak again. +In a minute or two the Caterpillar took the hookah out of its +mouth and yawned once or twice, and shook itself. Then it got +down off the mushroom, and crawled away in the grass, merely +remarking as it went, `One side will make you grow taller, and +the other side will make you grow shorter.' + + `One side of WHAT? The other side of WHAT?' thought Alice to +herself. + + `Of the mushroom,' said the Caterpillar, just as if she had +asked it aloud; and in another moment it was out of sight. + + Alice remained looking thoughtfully at the mushroom for a +minute, trying to make out which were the two sides of it; and as +it was perfectly round, she found this a very difficult question. +However, at last she stretched her arms round it as far as they +would go, and broke off a bit of the edge with each hand. + + `And now which is which?' she said to herself, and nibbled a +little of the right-hand bit to try the effect: the next moment +she felt a violent blow underneath her chin: it had struck her +foot! + + She was a good deal frightened by this very sudden change, but +she felt that there was no time to be lost, as she was shrinking +rapidly; so she set to work at once to eat some of the other bit. +Her chin was pressed so closely against her foot, that there was +hardly room to open her mouth; but she did it at last, and +managed to swallow a morsel of the lefthand bit. + + + * * * * * * * + + * * * * * * + + * * * * * * * + + `Come, my head's free at last!' said Alice in a tone of +delight, which changed into alarm in another moment, when she +found that her shoulders were nowhere to be found: all she could +see, when she looked down, was an immense length of neck, which +seemed to rise like a stalk out of a sea of green leaves that lay +far below her. + + `What CAN all that green stuff be?' said Alice. `And where +HAVE my shoulders got to? And oh, my poor hands, how is it I +can't see you?' She was moving them about as she spoke, but no +result seemed to follow, except a little shaking among the +distant green leaves. + + As there seemed to be no chance of getting her hands up to her +head, she tried to get her head down to them, and was delighted +to find that her neck would bend about easily in any direction, +like a serpent. She had just succeeded in curving it down into a +graceful zigzag, and was going to dive in among the leaves, which +she found to be nothing but the tops of the trees under which she +had been wandering, when a sharp hiss made her draw back in a +hurry: a large pigeon had flown into her face, and was beating +her violently with its wings. + + `Serpent!' screamed the Pigeon. + + `I'm NOT a serpent!' said Alice indignantly. `Let me alone!' + + `Serpent, I say again!' repeated the Pigeon, but in a more +subdued tone, and added with a kind of sob, `I've tried every +way, and nothing seems to suit them!' + + `I haven't the least idea what you're talking about,' said +Alice. + + `I've tried the roots of trees, and I've tried banks, and I've +tried hedges,' the Pigeon went on, without attending to her; `but +those serpents! There's no pleasing them!' + + Alice was more and more puzzled, but she thought there was no +use in saying anything more till the Pigeon had finished. + + `As if it wasn't trouble enough hatching the eggs,' said the +Pigeon; `but I must be on the look-out for serpents night and +day! Why, I haven't had a wink of sleep these three weeks!' + + `I'm very sorry you've been annoyed,' said Alice, who was +beginning to see its meaning. + + `And just as I'd taken the highest tree in the wood,' continued +the Pigeon, raising its voice to a shriek, `and just as I was +thinking I should be free of them at last, they must needs come +wriggling down from the sky! Ugh, Serpent!' + + `But I'm NOT a serpent, I tell you!' said Alice. `I'm a--I'm +a--' + + `Well! WHAT are you?' said the Pigeon. `I can see you're +trying to invent something!' + + `I--I'm a little girl,' said Alice, rather doubtfully, as she +remembered the number of changes she had gone through that day. + + `A likely story indeed!' said the Pigeon in a tone of the +deepest contempt. `I've seen a good many little girls in my +time, but never ONE with such a neck as that! No, no! You're a +serpent; and there's no use denying it. I suppose you'll be +telling me next that you never tasted an egg!' + + `I HAVE tasted eggs, certainly,' said Alice, who was a very +truthful child; `but little girls eat eggs quite as much as +serpents do, you know.' + + `I don't believe it,' said the Pigeon; `but if they do, why +then they're a kind of serpent, that's all I can say.' + + This was such a new idea to Alice, that she was quite silent +for a minute or two, which gave the Pigeon the opportunity of +adding, `You're looking for eggs, I know THAT well enough; and +what does it matter to me whether you're a little girl or a +serpent?' + + `It matters a good deal to ME,' said Alice hastily; `but I'm +not looking for eggs, as it happens; and if I was, I shouldn't +want YOURS: I don't like them raw.' + + `Well, be off, then!' said the Pigeon in a sulky tone, as it +settled down again into its nest. Alice crouched down among the +trees as well as she could, for her neck kept getting entangled +among the branches, and every now and then she had to stop and +untwist it. After a while she remembered that she still held the +pieces of mushroom in her hands, and she set to work very +carefully, nibbling first at one and then at the other, and +growing sometimes taller and sometimes shorter, until she had +succeeded in bringing herself down to her usual height. + + It was so long since she had been anything near the right size, +that it felt quite strange at first; but she got used to it in a +few minutes, and began talking to herself, as usual. `Come, +there's half my plan done now! How puzzling all these changes +are! I'm never sure what I'm going to be, from one minute to +another! However, I've got back to my right size: the next +thing is, to get into that beautiful garden--how IS that to be +done, I wonder?' As she said this, she came suddenly upon an +open place, with a little house in it about four feet high. +`Whoever lives there,' thought Alice, `it'll never do to come +upon them THIS size: why, I should frighten them out of their +wits!' So she began nibbling at the righthand bit again, and did +not venture to go near the house till she had brought herself +down to nine inches high. + + + + CHAPTER VI + + Pig and Pepper + + + For a minute or two she stood looking at the house, and +wondering what to do next, when suddenly a footman in livery came +running out of the wood--(she considered him to be a footman +because he was in livery: otherwise, judging by his face only, +she would have called him a fish)--and rapped loudly at the door +with his knuckles. It was opened by another footman in livery, +with a round face, and large eyes like a frog; and both footmen, +Alice noticed, had powdered hair that curled all over their +heads. She felt very curious to know what it was all about, and +crept a little way out of the wood to listen. + + The Fish-Footman began by producing from under his arm a great +letter, nearly as large as himself, and this he handed over to +the other, saying, in a solemn tone, `For the Duchess. An +invitation from the Queen to play croquet.' The Frog-Footman +repeated, in the same solemn tone, only changing the order of the +words a little, `From the Queen. An invitation for the Duchess +to play croquet.' + + Then they both bowed low, and their curls got entangled +together. + + Alice laughed so much at this, that she had to run back into +the wood for fear of their hearing her; and when she next peeped +out the Fish-Footman was gone, and the other was sitting on the +ground near the door, staring stupidly up into the sky. + + Alice went timidly up to the door, and knocked. + + `There's no sort of use in knocking,' said the Footman, `and +that for two reasons. First, because I'm on the same side of the +door as you are; secondly, because they're making such a noise +inside, no one could possibly hear you.' And certainly there was +a most extraordinary noise going on within--a constant howling +and sneezing, and every now and then a great crash, as if a dish +or kettle had been broken to pieces. + + `Please, then,' said Alice, `how am I to get in?' + + `There might be some sense in your knocking,' the Footman went +on without attending to her, `if we had the door between us. For +instance, if you were INSIDE, you might knock, and I could let +you out, you know.' He was looking up into the sky all the time +he was speaking, and this Alice thought decidedly uncivil. `But +perhaps he can't help it,' she said to herself; `his eyes are so +VERY nearly at the top of his head. But at any rate he might +answer questions.--How am I to get in?' she repeated, aloud. + + `I shall sit here,' the Footman remarked, `till tomorrow--' + + At this moment the door of the house opened, and a large plate +came skimming out, straight at the Footman's head: it just +grazed his nose, and broke to pieces against one of the trees +behind him. + + `--or next day, maybe,' the Footman continued in the same tone, +exactly as if nothing had happened. + + `How am I to get in?' asked Alice again, in a louder tone. + + `ARE you to get in at all?' said the Footman. `That's the +first question, you know.' + + It was, no doubt: only Alice did not like to be told so. +`It's really dreadful,' she muttered to herself, `the way all the +creatures argue. It's enough to drive one crazy!' + + The Footman seemed to think this a good opportunity for +repeating his remark, with variations. `I shall sit here,' he +said, `on and off, for days and days.' + + `But what am I to do?' said Alice. + + `Anything you like,' said the Footman, and began whistling. + + `Oh, there's no use in talking to him,' said Alice desperately: +`he's perfectly idiotic!' And she opened the door and went in. + + The door led right into a large kitchen, which was full of +smoke from one end to the other: the Duchess was sitting on a +three-legged stool in the middle, nursing a baby; the cook was +leaning over the fire, stirring a large cauldron which seemed to +be full of soup. + + `There's certainly too much pepper in that soup!' Alice said to +herself, as well as she could for sneezing. + + There was certainly too much of it in the air. Even the +Duchess sneezed occasionally; and as for the baby, it was +sneezing and howling alternately without a moment's pause. The +only things in the kitchen that did not sneeze, were the cook, +and a large cat which was sitting on the hearth and grinning from +ear to ear. + + `Please would you tell me,' said Alice, a little timidly, for +she was not quite sure whether it was good manners for her to +speak first, `why your cat grins like that?' + + `It's a Cheshire cat,' said the Duchess, `and that's why. +Pig!' + + She said the last word with such sudden violence that Alice +quite jumped; but she saw in another moment that it was addressed +to the baby, and not to her, so she took courage, and went on +again:-- + + `I didn't know that Cheshire cats always grinned; in fact, I +didn't know that cats COULD grin.' + + `They all can,' said the Duchess; `and most of 'em do.' + + `I don't know of any that do,' Alice said very politely, +feeling quite pleased to have got into a conversation. + + `You don't know much,' said the Duchess; `and that's a fact.' + + Alice did not at all like the tone of this remark, and thought +it would be as well to introduce some other subject of +conversation. While she was trying to fix on one, the cook took +the cauldron of soup off the fire, and at once set to work +throwing everything within her reach at the Duchess and the baby +--the fire-irons came first; then followed a shower of saucepans, +plates, and dishes. The Duchess took no notice of them even when +they hit her; and the baby was howling so much already, that it +was quite impossible to say whether the blows hurt it or not. + + `Oh, PLEASE mind what you're doing!' cried Alice, jumping up +and down in an agony of terror. `Oh, there goes his PRECIOUS +nose'; as an unusually large saucepan flew close by it, and very +nearly carried it off. + + `If everybody minded their own business,' the Duchess said in a +hoarse growl, `the world would go round a deal faster than it +does.' + + `Which would NOT be an advantage,' said Alice, who felt very +glad to get an opportunity of showing off a little of her +knowledge. `Just think of what work it would make with the day +and night! You see the earth takes twenty-four hours to turn +round on its axis--' + + `Talking of axes,' said the Duchess, `chop off her head!' + + Alice glanced rather anxiously at the cook, to see if she meant +to take the hint; but the cook was busily stirring the soup, and +seemed not to be listening, so she went on again: `Twenty-four +hours, I THINK; or is it twelve? I--' + + `Oh, don't bother ME,' said the Duchess; `I never could abide +figures!' And with that she began nursing her child again, +singing a sort of lullaby to it as she did so, and giving it a +violent shake at the end of every line: + + `Speak roughly to your little boy, + And beat him when he sneezes: + He only does it to annoy, + Because he knows it teases.' + + CHORUS. + + (In which the cook and the baby joined):-- + + `Wow! wow! wow!' + + While the Duchess sang the second verse of the song, she kept +tossing the baby violently up and down, and the poor little thing +howled so, that Alice could hardly hear the words:-- + + `I speak severely to my boy, + I beat him when he sneezes; + For he can thoroughly enjoy + The pepper when he pleases!' + + CHORUS. + + `Wow! wow! wow!' + + `Here! you may nurse it a bit, if you like!' the Duchess said +to Alice, flinging the baby at her as she spoke. `I must go and +get ready to play croquet with the Queen,' and she hurried out of +the room. The cook threw a frying-pan after her as she went out, +but it just missed her. + + Alice caught the baby with some difficulty, as it was a queer- +shaped little creature, and held out its arms and legs in all +directions, `just like a star-fish,' thought Alice. The poor +little thing was snorting like a steam-engine when she caught it, +and kept doubling itself up and straightening itself out again, +so that altogether, for the first minute or two, it was as much +as she could do to hold it. + + As soon as she had made out the proper way of nursing it, +(which was to twist it up into a sort of knot, and then keep +tight hold of its right ear and left foot, so as to prevent its +undoing itself,) she carried it out into the open air. `IF I +don't take this child away with me,' thought Alice, `they're sure +to kill it in a day or two: wouldn't it be murder to leave it +behind?' She said the last words out loud, and the little thing +grunted in reply (it had left off sneezing by this time). `Don't +grunt,' said Alice; `that's not at all a proper way of expressing +yourself.' + + The baby grunted again, and Alice looked very anxiously into +its face to see what was the matter with it. There could be no +doubt that it had a VERY turn-up nose, much more like a snout +than a real nose; also its eyes were getting extremely small for +a baby: altogether Alice did not like the look of the thing at +all. `But perhaps it was only sobbing,' she thought, and looked +into its eyes again, to see if there were any tears. + + No, there were no tears. `If you're going to turn into a pig, +my dear,' said Alice, seriously, `I'll have nothing more to do +with you. Mind now!' The poor little thing sobbed again (or +grunted, it was impossible to say which), and they went on for +some while in silence. + + Alice was just beginning to think to herself, `Now, what am I +to do with this creature when I get it home?' when it grunted +again, so violently, that she looked down into its face in some +alarm. This time there could be NO mistake about it: it was +neither more nor less than a pig, and she felt that it would be +quite absurd for her to carry it further. + + So she set the little creature down, and felt quite relieved to +see it trot away quietly into the wood. `If it had grown up,' +she said to herself, `it would have made a dreadfully ugly child: +but it makes rather a handsome pig, I think.' And she began +thinking over other children she knew, who might do very well as +pigs, and was just saying to herself, `if one only knew the right +way to change them--' when she was a little startled by seeing +the Cheshire Cat sitting on a bough of a tree a few yards off. + + The Cat only grinned when it saw Alice. It looked good- +natured, she thought: still it had VERY long claws and a great +many teeth, so she felt that it ought to be treated with respect. + + `Cheshire Puss,' she began, rather timidly, as she did not at +all know whether it would like the name: however, it only +grinned a little wider. `Come, it's pleased so far,' thought +Alice, and she went on. `Would you tell me, please, which way I +ought to go from here?' + + `That depends a good deal on where you want to get to,' said +the Cat. + + `I don't much care where--' said Alice. + + `Then it doesn't matter which way you go,' said the Cat. + + `--so long as I get SOMEWHERE,' Alice added as an explanation. + + `Oh, you're sure to do that,' said the Cat, `if you only walk +long enough.' + + Alice felt that this could not be denied, so she tried another +question. `What sort of people live about here?' + + `In THAT direction,' the Cat said, waving its right paw round, +`lives a Hatter: and in THAT direction,' waving the other paw, +`lives a March Hare. Visit either you like: they're both mad.' + + `But I don't want to go among mad people,' Alice remarked. + + `Oh, you can't help that,' said the Cat: `we're all mad here. +I'm mad. You're mad.' + + `How do you know I'm mad?' said Alice. + + `You must be,' said the Cat, `or you wouldn't have come here.' + + Alice didn't think that proved it at all; however, she went on +`And how do you know that you're mad?' + + `To begin with,' said the Cat, `a dog's not mad. You grant +that?' + + `I suppose so,' said Alice. + + `Well, then,' the Cat went on, `you see, a dog growls when it's +angry, and wags its tail when it's pleased. Now I growl when I'm +pleased, and wag my tail when I'm angry. Therefore I'm mad.' + + `I call it purring, not growling,' said Alice. + + `Call it what you like,' said the Cat. `Do you play croquet +with the Queen to-day?' + + `I should like it very much,' said Alice, `but I haven't been +invited yet.' + + `You'll see me there,' said the Cat, and vanished. + + Alice was not much surprised at this, she was getting so used +to queer things happening. While she was looking at the place +where it had been, it suddenly appeared again. + + `By-the-bye, what became of the baby?' said the Cat. `I'd +nearly forgotten to ask.' + + `It turned into a pig,' Alice quietly said, just as if it had +come back in a natural way. + + `I thought it would,' said the Cat, and vanished again. + + Alice waited a little, half expecting to see it again, but it +did not appear, and after a minute or two she walked on in the +direction in which the March Hare was said to live. `I've seen +hatters before,' she said to herself; `the March Hare will be +much the most interesting, and perhaps as this is May it won't be +raving mad--at least not so mad as it was in March.' As she said +this, she looked up, and there was the Cat again, sitting on a +branch of a tree. + + `Did you say pig, or fig?' said the Cat. + + `I said pig,' replied Alice; `and I wish you wouldn't keep +appearing and vanishing so suddenly: you make one quite giddy.' + + `All right,' said the Cat; and this time it vanished quite +slowly, beginning with the end of the tail, and ending with the +grin, which remained some time after the rest of it had gone. + + `Well! I've often seen a cat without a grin,' thought Alice; +`but a grin without a cat! It's the most curious thing I ever +say in my life!' + + She had not gone much farther before she came in sight of the +house of the March Hare: she thought it must be the right house, +because the chimneys were shaped like ears and the roof was +thatched with fur. It was so large a house, that she did not +like to go nearer till she had nibbled some more of the lefthand +bit of mushroom, and raised herself to about two feet high: even +then she walked up towards it rather timidly, saying to herself +`Suppose it should be raving mad after all! I almost wish I'd +gone to see the Hatter instead!' + + + + CHAPTER VII + + A Mad Tea-Party + + + There was a table set out under a tree in front of the house, +and the March Hare and the Hatter were having tea at it: a +Dormouse was sitting between them, fast asleep, and the other two +were using it as a cushion, resting their elbows on it, and the +talking over its head. `Very uncomfortable for the Dormouse,' +thought Alice; `only, as it's asleep, I suppose it doesn't mind.' + + The table was a large one, but the three were all crowded +together at one corner of it: `No room! No room!' they cried +out when they saw Alice coming. `There's PLENTY of room!' said +Alice indignantly, and she sat down in a large arm-chair at one +end of the table. + + `Have some wine,' the March Hare said in an encouraging tone. + + Alice looked all round the table, but there was nothing on it +but tea. `I don't see any wine,' she remarked. + + `There isn't any,' said the March Hare. + + `Then it wasn't very civil of you to offer it,' said Alice +angrily. + + `It wasn't very civil of you to sit down without being +invited,' said the March Hare. + + `I didn't know it was YOUR table,' said Alice; `it's laid for a +great many more than three.' + + `Your hair wants cutting,' said the Hatter. He had been +looking at Alice for some time with great curiosity, and this was +his first speech. + + `You should learn not to make personal remarks,' Alice said +with some severity; `it's very rude.' + + The Hatter opened his eyes very wide on hearing this; but all +he SAID was, `Why is a raven like a writing-desk?' + + `Come, we shall have some fun now!' thought Alice. `I'm glad +they've begun asking riddles.--I believe I can guess that,' she +added aloud. + + `Do you mean that you think you can find out the answer to it?' +said the March Hare. + + `Exactly so,' said Alice. + + `Then you should say what you mean,' the March Hare went on. + + `I do,' Alice hastily replied; `at least--at least I mean what +I say--that's the same thing, you know.' + + `Not the same thing a bit!' said the Hatter. `You might just +as well say that "I see what I eat" is the same thing as "I eat +what I see"!' + + `You might just as well say,' added the March Hare, `that "I +like what I get" is the same thing as "I get what I like"!' + + `You might just as well say,' added the Dormouse, who seemed to +be talking in his sleep, `that "I breathe when I sleep" is the +same thing as "I sleep when I breathe"!' + + `It IS the same thing with you,' said the Hatter, and here the +conversation dropped, and the party sat silent for a minute, +while Alice thought over all she could remember about ravens and +writing-desks, which wasn't much. + + The Hatter was the first to break the silence. `What day of +the month is it?' he said, turning to Alice: he had taken his +watch out of his pocket, and was looking at it uneasily, shaking +it every now and then, and holding it to his ear. + + Alice considered a little, and then said `The fourth.' + + `Two days wrong!' sighed the Hatter. `I told you butter +wouldn't suit the works!' he added looking angrily at the March +Hare. + + `It was the BEST butter,' the March Hare meekly replied. + + `Yes, but some crumbs must have got in as well,' the Hatter +grumbled: `you shouldn't have put it in with the bread-knife.' + + The March Hare took the watch and looked at it gloomily: then +he dipped it into his cup of tea, and looked at it again: but he +could think of nothing better to say than his first remark, `It +was the BEST butter, you know.' + + Alice had been looking over his shoulder with some curiosity. +`What a funny watch!' she remarked. `It tells the day of the +month, and doesn't tell what o'clock it is!' + + `Why should it?' muttered the Hatter. `Does YOUR watch tell +you what year it is?' + + `Of course not,' Alice replied very readily: `but that's +because it stays the same year for such a long time together.' + + `Which is just the case with MINE,' said the Hatter. + + Alice felt dreadfully puzzled. The Hatter's remark seemed to +have no sort of meaning in it, and yet it was certainly English. +`I don't quite understand you,' she said, as politely as she +could. + + `The Dormouse is asleep again,' said the Hatter, and he poured +a little hot tea upon its nose. + + The Dormouse shook its head impatiently, and said, without +opening its eyes, `Of course, of course; just what I was going to +remark myself.' + + `Have you guessed the riddle yet?' the Hatter said, turning to +Alice again. + + `No, I give it up,' Alice replied: `what's the answer?' + + `I haven't the slightest idea,' said the Hatter. + + `Nor I,' said the March Hare. + + Alice sighed wearily. `I think you might do something better +with the time,' she said, `than waste it in asking riddles that +have no answers.' + + `If you knew Time as well as I do,' said the Hatter, `you +wouldn't talk about wasting IT. It's HIM.' + + `I don't know what you mean,' said Alice. + + `Of course you don't!' the Hatter said, tossing his head +contemptuously. `I dare say you never even spoke to Time!' + + `Perhaps not,' Alice cautiously replied: `but I know I have to +beat time when I learn music.' + + `Ah! that accounts for it,' said the Hatter. `He won't stand +beating. Now, if you only kept on good terms with him, he'd do +almost anything you liked with the clock. For instance, suppose +it were nine o'clock in the morning, just time to begin lessons: +you'd only have to whisper a hint to Time, and round goes the +clock in a twinkling! Half-past one, time for dinner!' + + (`I only wish it was,' the March Hare said to itself in a +whisper.) + + `That would be grand, certainly,' said Alice thoughtfully: +`but then--I shouldn't be hungry for it, you know.' + + `Not at first, perhaps,' said the Hatter: `but you could keep +it to half-past one as long as you liked.' + + `Is that the way YOU manage?' Alice asked. + + The Hatter shook his head mournfully. `Not I!' he replied. +`We quarrelled last March--just before HE went mad, you know--' +(pointing with his tea spoon at the March Hare,) `--it was at the +great concert given by the Queen of Hearts, and I had to sing + + "Twinkle, twinkle, little bat! + How I wonder what you're at!" + +You know the song, perhaps?' + + `I've heard something like it,' said Alice. + + `It goes on, you know,' the Hatter continued, `in this way:-- + + "Up above the world you fly, + Like a tea-tray in the sky. + Twinkle, twinkle--"' + +Here the Dormouse shook itself, and began singing in its sleep +`Twinkle, twinkle, twinkle, twinkle--' and went on so long that +they had to pinch it to make it stop. + + `Well, I'd hardly finished the first verse,' said the Hatter, +`when the Queen jumped up and bawled out, "He's murdering the +time! Off with his head!"' + + `How dreadfully savage!' exclaimed Alice. + + `And ever since that,' the Hatter went on in a mournful tone, +`he won't do a thing I ask! It's always six o'clock now.' + + A bright idea came into Alice's head. `Is that the reason so +many tea-things are put out here?' she asked. + + `Yes, that's it,' said the Hatter with a sigh: `it's always +tea-time, and we've no time to wash the things between whiles.' + + `Then you keep moving round, I suppose?' said Alice. + + `Exactly so,' said the Hatter: `as the things get used up.' + + `But what happens when you come to the beginning again?' Alice +ventured to ask. + + `Suppose we change the subject,' the March Hare interrupted, +yawning. `I'm getting tired of this. I vote the young lady +tells us a story.' + + `I'm afraid I don't know one,' said Alice, rather alarmed at +the proposal. + + `Then the Dormouse shall!' they both cried. `Wake up, +Dormouse!' And they pinched it on both sides at once. + + The Dormouse slowly opened his eyes. `I wasn't asleep,' he +said in a hoarse, feeble voice: `I heard every word you fellows +were saying.' + + `Tell us a story!' said the March Hare. + + `Yes, please do!' pleaded Alice. + + `And be quick about it,' added the Hatter, `or you'll be asleep +again before it's done.' + + `Once upon a time there were three little sisters,' the +Dormouse began in a great hurry; `and their names were Elsie, +Lacie, and Tillie; and they lived at the bottom of a well--' + + `What did they live on?' said Alice, who always took a great +interest in questions of eating and drinking. + + `They lived on treacle,' said the Dormouse, after thinking a +minute or two. + + `They couldn't have done that, you know,' Alice gently +remarked; `they'd have been ill.' + + `So they were,' said the Dormouse; `VERY ill.' + + Alice tried to fancy to herself what such an extraordinary ways +of living would be like, but it puzzled her too much, so she went +on: `But why did they live at the bottom of a well?' + + `Take some more tea,' the March Hare said to Alice, very +earnestly. + + `I've had nothing yet,' Alice replied in an offended tone, `so +I can't take more.' + + `You mean you can't take LESS,' said the Hatter: `it's very +easy to take MORE than nothing.' + + `Nobody asked YOUR opinion,' said Alice. + + `Who's making personal remarks now?' the Hatter asked +triumphantly. + + Alice did not quite know what to say to this: so she helped +herself to some tea and bread-and-butter, and then turned to the +Dormouse, and repeated her question. `Why did they live at the +bottom of a well?' + + The Dormouse again took a minute or two to think about it, and +then said, `It was a treacle-well.' + + `There's no such thing!' Alice was beginning very angrily, but +the Hatter and the March Hare went `Sh! sh!' and the Dormouse +sulkily remarked, `If you can't be civil, you'd better finish the +story for yourself.' + + `No, please go on!' Alice said very humbly; `I won't interrupt +again. I dare say there may be ONE.' + + `One, indeed!' said the Dormouse indignantly. However, he +consented to go on. `And so these three little sisters--they +were learning to draw, you know--' + + `What did they draw?' said Alice, quite forgetting her promise. + + `Treacle,' said the Dormouse, without considering at all this +time. + + `I want a clean cup,' interrupted the Hatter: `let's all move +one place on.' + + He moved on as he spoke, and the Dormouse followed him: the +March Hare moved into the Dormouse's place, and Alice rather +unwillingly took the place of the March Hare. The Hatter was the +only one who got any advantage from the change: and Alice was a +good deal worse off than before, as the March Hare had just upset +the milk-jug into his plate. + + Alice did not wish to offend the Dormouse again, so she began +very cautiously: `But I don't understand. Where did they draw +the treacle from?' + + `You can draw water out of a water-well,' said the Hatter; `so +I should think you could draw treacle out of a treacle-well--eh, +stupid?' + + `But they were IN the well,' Alice said to the Dormouse, not +choosing to notice this last remark. + + `Of course they were', said the Dormouse; `--well in.' + + This answer so confused poor Alice, that she let the Dormouse +go on for some time without interrupting it. + + `They were learning to draw,' the Dormouse went on, yawning and +rubbing its eyes, for it was getting very sleepy; `and they drew +all manner of things--everything that begins with an M--' + + `Why with an M?' said Alice. + + `Why not?' said the March Hare. + + Alice was silent. + + The Dormouse had closed its eyes by this time, and was going +off into a doze; but, on being pinched by the Hatter, it woke up +again with a little shriek, and went on: `--that begins with an +M, such as mouse-traps, and the moon, and memory, and muchness-- +you know you say things are "much of a muchness"--did you ever +see such a thing as a drawing of a muchness?' + + `Really, now you ask me,' said Alice, very much confused, `I +don't think--' + + `Then you shouldn't talk,' said the Hatter. + + This piece of rudeness was more than Alice could bear: she got +up in great disgust, and walked off; the Dormouse fell asleep +instantly, and neither of the others took the least notice of her +going, though she looked back once or twice, half hoping that +they would call after her: the last time she saw them, they were +trying to put the Dormouse into the teapot. + + `At any rate I'll never go THERE again!' said Alice as she +picked her way through the wood. `It's the stupidest tea-party I +ever was at in all my life!' + + Just as she said this, she noticed that one of the trees had a +door leading right into it. `That's very curious!' she thought. +`But everything's curious today. I think I may as well go in at +once.' And in she went. + + Once more she found herself in the long hall, and close to the +little glass table. `Now, I'll manage better this time,' she +said to herself, and began by taking the little golden key, and +unlocking the door that led into the garden. Then she went to +work nibbling at the mushroom (she had kept a piece of it in her +pocked) till she was about a foot high: then she walked down the +little passage: and THEN--she found herself at last in the +beautiful garden, among the bright flower-beds and the cool +fountains. + + + + CHAPTER VIII + + The Queen's Croquet-Ground + + + A large rose-tree stood near the entrance of the garden: the +roses growing on it were white, but there were three gardeners at +it, busily painting them red. Alice thought this a very curious +thing, and she went nearer to watch them, and just as she came up +to them she heard one of them say, `Look out now, Five! Don't go +splashing paint over me like that!' + + `I couldn't help it,' said Five, in a sulky tone; `Seven jogged +my elbow.' + + On which Seven looked up and said, `That's right, Five! Always +lay the blame on others!' + + `YOU'D better not talk!' said Five. `I heard the Queen say only +yesterday you deserved to be beheaded!' + + `What for?' said the one who had spoken first. + + `That's none of YOUR business, Two!' said Seven. + + `Yes, it IS his business!' said Five, `and I'll tell him--it +was for bringing the cook tulip-roots instead of onions.' + + Seven flung down his brush, and had just begun `Well, of all +the unjust things--' when his eye chanced to fall upon Alice, as +she stood watching them, and he checked himself suddenly: the +others looked round also, and all of them bowed low. + + `Would you tell me,' said Alice, a little timidly, `why you are +painting those roses?' + + Five and Seven said nothing, but looked at Two. Two began in a +low voice, `Why the fact is, you see, Miss, this here ought to +have been a RED rose-tree, and we put a white one in by mistake; +and if the Queen was to find it out, we should all have our heads +cut off, you know. So you see, Miss, we're doing our best, afore +she comes, to--' At this moment Five, who had been anxiously +looking across the garden, called out `The Queen! The Queen!' +and the three gardeners instantly threw themselves flat upon +their faces. There was a sound of many footsteps, and Alice +looked round, eager to see the Queen. + + First came ten soldiers carrying clubs; these were all shaped +like the three gardeners, oblong and flat, with their hands and +feet at the corners: next the ten courtiers; these were +ornamented all over with diamonds, and walked two and two, as the +soldiers did. After these came the royal children; there were +ten of them, and the little dears came jumping merrily along hand +in hand, in couples: they were all ornamented with hearts. Next +came the guests, mostly Kings and Queens, and among them Alice +recognised the White Rabbit: it was talking in a hurried nervous +manner, smiling at everything that was said, and went by without +noticing her. Then followed the Knave of Hearts, carrying the +King's crown on a crimson velvet cushion; and, last of all this +grand procession, came THE KING AND QUEEN OF HEARTS. + + Alice was rather doubtful whether she ought not to lie down on +her face like the three gardeners, but she could not remember +every having heard of such a rule at processions; `and besides, +what would be the use of a procession,' thought she, `if people +had all to lie down upon their faces, so that they couldn't see +it?' So she stood still where she was, and waited. + + When the procession came opposite to Alice, they all stopped +and looked at her, and the Queen said severely `Who is this?' +She said it to the Knave of Hearts, who only bowed and smiled in +reply. + + `Idiot!' said the Queen, tossing her head impatiently; and, +turning to Alice, she went on, `What's your name, child?' + + `My name is Alice, so please your Majesty,' said Alice very +politely; but she added, to herself, `Why, they're only a pack of +cards, after all. I needn't be afraid of them!' + + `And who are THESE?' said the Queen, pointing to the three +gardeners who were lying round the rosetree; for, you see, as +they were lying on their faces, and the pattern on their backs +was the same as the rest of the pack, she could not tell whether +they were gardeners, or soldiers, or courtiers, or three of her +own children. + + `How should I know?' said Alice, surprised at her own courage. +`It's no business of MINE.' + + The Queen turned crimson with fury, and, after glaring at her +for a moment like a wild beast, screamed `Off with her head! +Off--' + + `Nonsense!' said Alice, very loudly and decidedly, and the +Queen was silent. + + The King laid his hand upon her arm, and timidly said +`Consider, my dear: she is only a child!' + + The Queen turned angrily away from him, and said to the Knave +`Turn them over!' + + The Knave did so, very carefully, with one foot. + + `Get up!' said the Queen, in a shrill, loud voice, and the +three gardeners instantly jumped up, and began bowing to the +King, the Queen, the royal children, and everybody else. + + `Leave off that!' screamed the Queen. `You make me giddy.' +And then, turning to the rose-tree, she went on, `What HAVE you +been doing here?' + + `May it please your Majesty,' said Two, in a very humble tone, +going down on one knee as he spoke, `we were trying--' + + `I see!' said the Queen, who had meanwhile been examining the +roses. `Off with their heads!' and the procession moved on, +three of the soldiers remaining behind to execute the unfortunate +gardeners, who ran to Alice for protection. + + `You shan't be beheaded!' said Alice, and she put them into a +large flower-pot that stood near. The three soldiers wandered +about for a minute or two, looking for them, and then quietly +marched off after the others. + + `Are their heads off?' shouted the Queen. + + `Their heads are gone, if it please your Majesty!' the soldiers +shouted in reply. + + `That's right!' shouted the Queen. `Can you play croquet?' + + The soldiers were silent, and looked at Alice, as the question +was evidently meant for her. + + `Yes!' shouted Alice. + + `Come on, then!' roared the Queen, and Alice joined the +procession, wondering very much what would happen next. + + `It's--it's a very fine day!' said a timid voice at her side. +She was walking by the White Rabbit, who was peeping anxiously +into her face. + + `Very,' said Alice: `--where's the Duchess?' + + `Hush! Hush!' said the Rabbit in a low, hurried tone. He +looked anxiously over his shoulder as he spoke, and then raised +himself upon tiptoe, put his mouth close to her ear, and +whispered `She's under sentence of execution.' + + `What for?' said Alice. + + `Did you say "What a pity!"?' the Rabbit asked. + + `No, I didn't,' said Alice: `I don't think it's at all a pity. +I said "What for?"' + + `She boxed the Queen's ears--' the Rabbit began. Alice gave a +little scream of laughter. `Oh, hush!' the Rabbit whispered in a +frightened tone. `The Queen will hear you! You see, she came +rather late, and the Queen said--' + + `Get to your places!' shouted the Queen in a voice of thunder, +and people began running about in all directions, tumbling up +against each other; however, they got settled down in a minute or +two, and the game began. Alice thought she had never seen such a +curious croquet-ground in her life; it was all ridges and +furrows; the balls were live hedgehogs, the mallets live +flamingoes, and the soldiers had to double themselves up and to +stand on their hands and feet, to make the arches. + + The chief difficulty Alice found at first was in managing her +flamingo: she succeeded in getting its body tucked away, +comfortably enough, under her arm, with its legs hanging down, +but generally, just as she had got its neck nicely straightened +out, and was going to give the hedgehog a blow with its head, it +WOULD twist itself round and look up in her face, with such a +puzzled expression that she could not help bursting out laughing: +and when she had got its head down, and was going to begin again, +it was very provoking to find that the hedgehog had unrolled +itself, and was in the act of crawling away: besides all this, +there was generally a ridge or furrow in the way wherever she +wanted to send the hedgehog to, and, as the doubled-up soldiers +were always getting up and walking off to other parts of the +ground, Alice soon came to the conclusion that it was a very +difficult game indeed. + + The players all played at once without waiting for turns, +quarrelling all the while, and fighting for the hedgehogs; and in +a very short time the Queen was in a furious passion, and went +stamping about, and shouting `Off with his head!' or `Off with +her head!' about once in a minute. + + Alice began to feel very uneasy: to be sure, she had not as +yet had any dispute with the Queen, but she knew that it might +happen any minute, `and then,' thought she, `what would become of +me? They're dreadfully fond of beheading people here; the great +wonder is, that there's any one left alive!' + + She was looking about for some way of escape, and wondering +whether she could get away without being seen, when she noticed a +curious appearance in the air: it puzzled her very much at +first, but, after watching it a minute or two, she made it out to +be a grin, and she said to herself `It's the Cheshire Cat: now I +shall have somebody to talk to.' + + `How are you getting on?' said the Cat, as soon as there was +mouth enough for it to speak with. + + Alice waited till the eyes appeared, and then nodded. `It's no +use speaking to it,' she thought, `till its ears have come, or at +least one of them.' In another minute the whole head appeared, +and then Alice put down her flamingo, and began an account of the +game, feeling very glad she had someone to listen to her. The +Cat seemed to think that there was enough of it now in sight, and +no more of it appeared. + + `I don't think they play at all fairly,' Alice began, in rather +a complaining tone, `and they all quarrel so dreadfully one can't +hear oneself speak--and they don't seem to have any rules in +particular; at least, if there are, nobody attends to them--and +you've no idea how confusing it is all the things being alive; +for instance, there's the arch I've got to go through next +walking about at the other end of the ground--and I should have +croqueted the Queen's hedgehog just now, only it ran away when it +saw mine coming!' + + `How do you like the Queen?' said the Cat in a low voice. + + `Not at all,' said Alice: `she's so extremely--' Just then +she noticed that the Queen was close behind her, listening: so +she went on, `--likely to win, that it's hardly worth while +finishing the game.' + + The Queen smiled and passed on. + + `Who ARE you talking to?' said the King, going up to Alice, and +looking at the Cat's head with great curiosity. + + `It's a friend of mine--a Cheshire Cat,' said Alice: `allow me +to introduce it.' + + `I don't like the look of it at all,' said the King: `however, +it may kiss my hand if it likes.' + + `I'd rather not,' the Cat remarked. + + `Don't be impertinent,' said the King, `and don't look at me +like that!' He got behind Alice as he spoke. + + `A cat may look at a king,' said Alice. `I've read that in +some book, but I don't remember where.' + + `Well, it must be removed,' said the King very decidedly, and +he called the Queen, who was passing at the moment, `My dear! I +wish you would have this cat removed!' + + The Queen had only one way of settling all difficulties, great +or small. `Off with his head!' she said, without even looking +round. + + `I'll fetch the executioner myself,' said the King eagerly, and +he hurried off. + + Alice thought she might as well go back, and see how the game +was going on, as she heard the Queen's voice in the distance, +screaming with passion. She had already heard her sentence three +of the players to be executed for having missed their turns, and +she did not like the look of things at all, as the game was in +such confusion that she never knew whether it was her turn or +not. So she went in search of her hedgehog. + + The hedgehog was engaged in a fight with another hedgehog, +which seemed to Alice an excellent opportunity for croqueting one +of them with the other: the only difficulty was, that her +flamingo was gone across to the other side of the garden, where +Alice could see it trying in a helpless sort of way to fly up +into a tree. + + By the time she had caught the flamingo and brought it back, +the fight was over, and both the hedgehogs were out of sight: +`but it doesn't matter much,' thought Alice, `as all the arches +are gone from this side of the ground.' So she tucked it away +under her arm, that it might not escape again, and went back for +a little more conversation with her friend. + + When she got back to the Cheshire Cat, she was surprised to +find quite a large crowd collected round it: there was a dispute +going on between the executioner, the King, and the Queen, who +were all talking at once, while all the rest were quite silent, +and looked very uncomfortable. + + The moment Alice appeared, she was appealed to by all three to +settle the question, and they repeated their arguments to her, +though, as they all spoke at once, she found it very hard indeed +to make out exactly what they said. + + The executioner's argument was, that you couldn't cut off a +head unless there was a body to cut it off from: that he had +never had to do such a thing before, and he wasn't going to begin +at HIS time of life. + + The King's argument was, that anything that had a head could be +beheaded, and that you weren't to talk nonsense. + + The Queen's argument was, that if something wasn't done about +it in less than no time she'd have everybody executed, all round. +(It was this last remark that had made the whole party look so +grave and anxious.) + + Alice could think of nothing else to say but `It belongs to the +Duchess: you'd better ask HER about it.' + + `She's in prison,' the Queen said to the executioner: `fetch +her here.' And the executioner went off like an arrow. + + The Cat's head began fading away the moment he was gone, and, +by the time he had come back with the Dutchess, it had entirely +disappeared; so the King and the executioner ran wildly up and +down looking for it, while the rest of the party went back to the game. + + + + CHAPTER IX + + The Mock Turtle's Story + + + `You can't think how glad I am to see you again, you dear old +thing!' said the Duchess, as she tucked her arm affectionately +into Alice's, and they walked off together. + + Alice was very glad to find her in such a pleasant temper, and +thought to herself that perhaps it was only the pepper that had +made her so savage when they met in the kitchen. + + `When I'M a Duchess,' she said to herself, (not in a very +hopeful tone though), `I won't have any pepper in my kitchen AT +ALL. Soup does very well without--Maybe it's always pepper that +makes people hot-tempered,' she went on, very much pleased at +having found out a new kind of rule, `and vinegar that makes them +sour--and camomile that makes them bitter--and--and barley-sugar +and such things that make children sweet-tempered. I only wish +people knew that: then they wouldn't be so stingy about it, you +know--' + + She had quite forgotten the Duchess by this time, and was a +little startled when she heard her voice close to her ear. +`You're thinking about something, my dear, and that makes you +forget to talk. I can't tell you just now what the moral of that +is, but I shall remember it in a bit.' + + `Perhaps it hasn't one,' Alice ventured to remark. + + `Tut, tut, child!' said the Duchess. `Everything's got a +moral, if only you can find it.' And she squeezed herself up +closer to Alice's side as she spoke. + + Alice did not much like keeping so close to her: first, +because the Duchess was VERY ugly; and secondly, because she was +exactly the right height to rest her chin upon Alice's shoulder, +and it was an uncomfortably sharp chin. However, she did not +like to be rude, so she bore it as well as she could. + + `The game's going on rather better now,' she said, by way of +keeping up the conversation a little. + + `'Tis so,' said the Duchess: `and the moral of that is--"Oh, +'tis love, 'tis love, that makes the world go round!"' + + `Somebody said,' Alice whispered, `that it's done by everybody +minding their own business!' + + `Ah, well! It means much the same thing,' said the Duchess, +digging her sharp little chin into Alice's shoulder as she added, +`and the moral of THAT is--"Take care of the sense, and the +sounds will take care of themselves."' + + `How fond she is of finding morals in things!' Alice thought to +herself. + + `I dare say you're wondering why I don't put my arm round your +waist,' the Duchess said after a pause: `the reason is, that I'm +doubtful about the temper of your flamingo. Shall I try the +experiment?' + + `HE might bite,' Alice cautiously replied, not feeling at all +anxious to have the experiment tried. + + `Very true,' said the Duchess: `flamingoes and mustard both +bite. And the moral of that is--"Birds of a feather flock +together."' + + `Only mustard isn't a bird,' Alice remarked. + + `Right, as usual,' said the Duchess: `what a clear way you +have of putting things!' + + `It's a mineral, I THINK,' said Alice. + + `Of course it is,' said the Duchess, who seemed ready to agree +to everything that Alice said; `there's a large mustard-mine near +here. And the moral of that is--"The more there is of mine, the +less there is of yours."' + + `Oh, I know!' exclaimed Alice, who had not attended to this +last remark, `it's a vegetable. It doesn't look like one, but it +is.' + + `I quite agree with you,' said the Duchess; `and the moral of +that is--"Be what you would seem to be"--or if you'd like it put +more simply--"Never imagine yourself not to be otherwise than +what it might appear to others that what you were or might have +been was not otherwise than what you had been would have appeared +to them to be otherwise."' + + `I think I should understand that better,' Alice said very +politely, `if I had it written down: but I can't quite follow it +as you say it.' + + `That's nothing to what I could say if I chose,' the Duchess +replied, in a pleased tone. + + `Pray don't trouble yourself to say it any longer than that,' +said Alice. + + `Oh, don't talk about trouble!' said the Duchess. `I make you +a present of everything I've said as yet.' + + `A cheap sort of present!' thought Alice. `I'm glad they don't +give birthday presents like that!' But she did not venture to +say it out loud. + + `Thinking again?' the Duchess asked, with another dig of her +sharp little chin. + + `I've a right to think,' said Alice sharply, for she was +beginning to feel a little worried. + + `Just about as much right,' said the Duchess, `as pigs have to +fly; and the m--' + + But here, to Alice's great surprise, the Duchess's voice died +away, even in the middle of her favourite word `moral,' and the +arm that was linked into hers began to tremble. Alice looked up, +and there stood the Queen in front of them, with her arms folded, +frowning like a thunderstorm. + + `A fine day, your Majesty!' the Duchess began in a low, weak +voice. + + `Now, I give you fair warning,' shouted the Queen, stamping on +the ground as she spoke; `either you or your head must be off, +and that in about half no time! Take your choice!' + + The Duchess took her choice, and was gone in a moment. + + `Let's go on with the game,' the Queen said to Alice; and Alice +was too much frightened to say a word, but slowly followed her +back to the croquet-ground. + + The other guests had taken advantage of the Queen's absence, +and were resting in the shade: however, the moment they saw her, +they hurried back to the game, the Queen merely remarking that a +moment's delay would cost them their lives. + + All the time they were playing the Queen never left off +quarrelling with the other players, and shouting `Off with his +head!' or `Off with her head!' Those whom she sentenced were +taken into custody by the soldiers, who of course had to leave +off being arches to do this, so that by the end of half an hour +or so there were no arches left, and all the players, except the +King, the Queen, and Alice, were in custody and under sentence of +execution. + + Then the Queen left off, quite out of breath, and said to +Alice, `Have you seen the Mock Turtle yet?' + + `No,' said Alice. `I don't even know what a Mock Turtle is.' + + `It's the thing Mock Turtle Soup is made from,' said the Queen. + + `I never saw one, or heard of one,' said Alice. + + `Come on, then,' said the Queen, `and he shall tell you his +history,' + + As they walked off together, Alice heard the King say in a low +voice, to the company generally, `You are all pardoned.' `Come, +THAT'S a good thing!' she said to herself, for she had felt quite +unhappy at the number of executions the Queen had ordered. + + They very soon came upon a Gryphon, lying fast asleep in the +sun. (IF you don't know what a Gryphon is, look at the picture.) +`Up, lazy thing!' said the Queen, `and take this young lady to +see the Mock Turtle, and to hear his history. I must go back and +see after some executions I have ordered'; and she walked off, +leaving Alice alone with the Gryphon. Alice did not quite like +the look of the creature, but on the whole she thought it would +be quite as safe to stay with it as to go after that savage +Queen: so she waited. + + The Gryphon sat up and rubbed its eyes: then it watched the +Queen till she was out of sight: then it chuckled. `What fun!' +said the Gryphon, half to itself, half to Alice. + + `What IS the fun?' said Alice. + + `Why, SHE,' said the Gryphon. `It's all her fancy, that: they +never executes nobody, you know. Come on!' + + `Everybody says "come on!" here,' thought Alice, as she went +slowly after it: `I never was so ordered about in all my life, +never!' + + They had not gone far before they saw the Mock Turtle in the +distance, sitting sad and lonely on a little ledge of rock, and, +as they came nearer, Alice could hear him sighing as if his heart +would break. She pitied him deeply. `What is his sorrow?' she +asked the Gryphon, and the Gryphon answered, very nearly in the +same words as before, `It's all his fancy, that: he hasn't got +no sorrow, you know. Come on!' + + So they went up to the Mock Turtle, who looked at them with +large eyes full of tears, but said nothing. + + `This here young lady,' said the Gryphon, `she wants for to +know your history, she do.' + + `I'll tell it her,' said the Mock Turtle in a deep, hollow +tone: `sit down, both of you, and don't speak a word till I've +finished.' + + So they sat down, and nobody spoke for some minutes. Alice +thought to herself, `I don't see how he can EVEN finish, if he +doesn't begin.' But she waited patiently. + + `Once,' said the Mock Turtle at last, with a deep sigh, `I was +a real Turtle.' + + These words were followed by a very long silence, broken only +by an occasional exclamation of `Hjckrrh!' from the Gryphon, and +the constant heavy sobbing of the Mock Turtle. Alice was very +nearly getting up and saying, `Thank you, sir, for your +interesting story,' but she could not help thinking there MUST be +more to come, so she sat still and said nothing. + + `When we were little,' the Mock Turtle went on at last, more +calmly, though still sobbing a little now and then, `we went to +school in the sea. The master was an old Turtle--we used to call +him Tortoise--' + + `Why did you call him Tortoise, if he wasn't one?' Alice asked. + + `We called him Tortoise because he taught us,' said the Mock +Turtle angrily: `really you are very dull!' + + `You ought to be ashamed of yourself for asking such a simple +question,' added the Gryphon; and then they both sat silent and +looked at poor Alice, who felt ready to sink into the earth. At +last the Gryphon said to the Mock Turtle, `Drive on, old fellow! +Don't be all day about it!' and he went on in these words: + + `Yes, we went to school in the sea, though you mayn't believe +it--' + + `I never said I didn't!' interrupted Alice. + + `You did,' said the Mock Turtle. + + `Hold your tongue!' added the Gryphon, before Alice could speak +again. The Mock Turtle went on. + + `We had the best of educations--in fact, we went to school +every day--' + + `I'VE been to a day-school, too,' said Alice; `you needn't be +so proud as all that.' + + `With extras?' asked the Mock Turtle a little anxiously. + + `Yes,' said Alice, `we learned French and music.' + + `And washing?' said the Mock Turtle. + + `Certainly not!' said Alice indignantly. + + `Ah! then yours wasn't a really good school,' said the Mock +Turtle in a tone of great relief. `Now at OURS they had at the +end of the bill, "French, music, AND WASHING--extra."' + + `You couldn't have wanted it much,' said Alice; `living at the +bottom of the sea.' + + `I couldn't afford to learn it.' said the Mock Turtle with a +sigh. `I only took the regular course.' + + `What was that?' inquired Alice. + + `Reeling and Writhing, of course, to begin with,' the Mock +Turtle replied; `and then the different branches of Arithmetic-- +Ambition, Distraction, Uglification, and Derision.' + + `I never heard of "Uglification,"' Alice ventured to say. `What +is it?' + + The Gryphon lifted up both its paws in surprise. `What! Never +heard of uglifying!' it exclaimed. `You know what to beautify +is, I suppose?' + + `Yes,' said Alice doubtfully: `it means--to--make--anything-- +prettier.' + + `Well, then,' the Gryphon went on, `if you don't know what to +uglify is, you ARE a simpleton.' + + Alice did not feel encouraged to ask any more questions about +it, so she turned to the Mock Turtle, and said `What else had you +to learn?' + + `Well, there was Mystery,' the Mock Turtle replied, counting +off the subjects on his flappers, `--Mystery, ancient and modern, +with Seaography: then Drawling--the Drawling-master was an old +conger-eel, that used to come once a week: HE taught us +Drawling, Stretching, and Fainting in Coils.' + + `What was THAT like?' said Alice. + + `Well, I can't show it you myself,' the Mock Turtle said: `I'm +too stiff. And the Gryphon never learnt it.' + + `Hadn't time,' said the Gryphon: `I went to the Classics +master, though. He was an old crab, HE was.' + + `I never went to him,' the Mock Turtle said with a sigh: `he +taught Laughing and Grief, they used to say.' + + `So he did, so he did,' said the Gryphon, sighing in his turn; +and both creatures hid their faces in their paws. + + `And how many hours a day did you do lessons?' said Alice, in a +hurry to change the subject. + + `Ten hours the first day,' said the Mock Turtle: `nine the +next, and so on.' + + `What a curious plan!' exclaimed Alice. + + `That's the reason they're called lessons,' the Gryphon +remarked: `because they lessen from day to day.' + + This was quite a new idea to Alice, and she thought it over a +little before she made her next remark. `Then the eleventh day +must have been a holiday?' + + `Of course it was,' said the Mock Turtle. + + `And how did you manage on the twelfth?' Alice went on eagerly. + + `That's enough about lessons,' the Gryphon interrupted in a +very decided tone: `tell her something about the games now.' + + + + CHAPTER X + + The Lobster Quadrille + + + The Mock Turtle sighed deeply, and drew the back of one flapper +across his eyes. He looked at Alice, and tried to speak, but for +a minute or two sobs choked his voice. `Same as if he had a bone +in his throat,' said the Gryphon: and it set to work shaking him +and punching him in the back. At last the Mock Turtle recovered +his voice, and, with tears running down his cheeks, he went on +again:-- + + `You may not have lived much under the sea--' (`I haven't,' +said Alice)--`and perhaps you were never even introduced to a lobster--' +(Alice began to say `I once tasted--' but checked herself hastily, +and said `No, never') `--so you can have no idea what a delightful +thing a Lobster Quadrille is!' + + `No, indeed,' said Alice. `What sort of a dance is it?' + + `Why,' said the Gryphon, `you first form into a line along the +sea-shore--' + + `Two lines!' cried the Mock Turtle. `Seals, turtles, salmon, +and so on; then, when you've cleared all the jelly-fish out of +the way--' + + `THAT generally takes some time,' interrupted the Gryphon. + + `--you advance twice--' + + `Each with a lobster as a partner!' cried the Gryphon. + + `Of course,' the Mock Turtle said: `advance twice, set to +partners--' + + `--change lobsters, and retire in same order,' continued the +Gryphon. + + `Then, you know,' the Mock Turtle went on, `you throw the--' + + `The lobsters!' shouted the Gryphon, with a bound into the air. + + `--as far out to sea as you can--' + + `Swim after them!' screamed the Gryphon. + + `Turn a somersault in the sea!' cried the Mock Turtle, +capering wildly about. + + `Back to land again, and that's all the first figure,' said the +Mock Turtle, suddenly dropping his voice; and the two creatures, +who had been jumping about like mad things all this time, sat +down again very sadly and quietly, and looked at Alice. + + `It must be a very pretty dance,' said Alice timidly. + + `Would you like to see a little of it?' said the Mock Turtle. + + `Very much indeed,' said Alice. + + `Come, let's try the first figure!' said the Mock Turtle to the +Gryphon. `We can do without lobsters, you know. Which shall +sing?' + + `Oh, YOU sing,' said the Gryphon. `I've forgotten the words.' + + So they began solemnly dancing round and round Alice, every now +and then treading on her toes when they passed too close, and +waving their forepaws to mark the time, while the Mock Turtle +sang this, very slowly and sadly:-- + + +`"Will you walk a little faster?" said a whiting to a snail. +"There's a porpoise close behind us, and he's treading on my + tail. +See how eagerly the lobsters and the turtles all advance! +They are waiting on the shingle--will you come and join the +dance? + +Will you, won't you, will you, won't you, will you join the +dance? +Will you, won't you, will you, won't you, won't you join the +dance? + + +"You can really have no notion how delightful it will be +When they take us up and throw us, with the lobsters, out to + sea!" +But the snail replied "Too far, too far!" and gave a look + askance-- +Said he thanked the whiting kindly, but he would not join the + dance. + Would not, could not, would not, could not, would not join + the dance. + Would not, could not, would not, could not, could not join + the dance. + +`"What matters it how far we go?" his scaly friend replied. +"There is another shore, you know, upon the other side. +The further off from England the nearer is to France-- +Then turn not pale, beloved snail, but come and join the dance. + + Will you, won't you, will you, won't you, will you join the + dance? + Will you, won't you, will you, won't you, won't you join the + dance?"' + + + + `Thank you, it's a very interesting dance to watch,' said +Alice, feeling very glad that it was over at last: `and I do so +like that curious song about the whiting!' + + `Oh, as to the whiting,' said the Mock Turtle, `they--you've +seen them, of course?' + + `Yes,' said Alice, `I've often seen them at dinn--' she +checked herself hastily. + + `I don't know where Dinn may be,' said the Mock Turtle, `but +if you've seen them so often, of course you know what they're +like.' + + `I believe so,' Alice replied thoughtfully. `They have their +tails in their mouths--and they're all over crumbs.' + + `You're wrong about the crumbs,' said the Mock Turtle: +`crumbs would all wash off in the sea. But they HAVE their tails +in their mouths; and the reason is--' here the Mock Turtle +yawned and shut his eyes.--`Tell her about the reason and all +that,' he said to the Gryphon. + + `The reason is,' said the Gryphon, `that they WOULD go with +the lobsters to the dance. So they got thrown out to sea. So +they had to fall a long way. So they got their tails fast in +their mouths. So they couldn't get them out again. That's all.' + + `Thank you,' said Alice, `it's very interesting. I never knew +so much about a whiting before.' + + `I can tell you more than that, if you like,' said the +Gryphon. `Do you know why it's called a whiting?' + + `I never thought about it,' said Alice. `Why?' + + `IT DOES THE BOOTS AND SHOES.' the Gryphon replied very +solemnly. + + Alice was thoroughly puzzled. `Does the boots and shoes!' she +repeated in a wondering tone. + + `Why, what are YOUR shoes done with?' said the Gryphon. `I +mean, what makes them so shiny?' + + Alice looked down at them, and considered a little before she +gave her answer. `They're done with blacking, I believe.' + + `Boots and shoes under the sea,' the Gryphon went on in a deep +voice, `are done with a whiting. Now you know.' + + `And what are they made of?' Alice asked in a tone of great +curiosity. + + `Soles and eels, of course,' the Gryphon replied rather +impatiently: `any shrimp could have told you that.' + + `If I'd been the whiting,' said Alice, whose thoughts were +still running on the song, `I'd have said to the porpoise, "Keep +back, please: we don't want YOU with us!"' + + `They were obliged to have him with them,' the Mock Turtle +said: `no wise fish would go anywhere without a porpoise.' + + `Wouldn't it really?' said Alice in a tone of great surprise. + + `Of course not,' said the Mock Turtle: `why, if a fish came +to ME, and told me he was going a journey, I should say "With +what porpoise?"' + + `Don't you mean "purpose"?' said Alice. + + `I mean what I say,' the Mock Turtle replied in an offended +tone. And the Gryphon added `Come, let's hear some of YOUR +adventures.' + + `I could tell you my adventures--beginning from this morning,' +said Alice a little timidly: `but it's no use going back to +yesterday, because I was a different person then.' + + `Explain all that,' said the Mock Turtle. + + `No, no! The adventures first,' said the Gryphon in an +impatient tone: `explanations take such a dreadful time.' + + So Alice began telling them her adventures from the time when +she first saw the White Rabbit. She was a little nervous about +it just at first, the two creatures got so close to her, one on +each side, and opened their eyes and mouths so VERY wide, but she +gained courage as she went on. Her listeners were perfectly +quiet till she got to the part about her repeating `YOU ARE OLD, +FATHER WILLIAM,' to the Caterpillar, and the words all coming +different, and then the Mock Turtle drew a long breath, and said +`That's very curious.' + + `It's all about as curious as it can be,' said the Gryphon. + + `It all came different!' the Mock Turtle repeated +thoughtfully. `I should like to hear her try and repeat +something now. Tell her to begin.' He looked at the Gryphon as +if he thought it had some kind of authority over Alice. + + `Stand up and repeat "'TIS THE VOICE OF THE SLUGGARD,"' said +the Gryphon. + + `How the creatures order one about, and make one repeat +lessons!' thought Alice; `I might as well be at school at once.' +However, she got up, and began to repeat it, but her head was so +full of the Lobster Quadrille, that she hardly knew what she was +saying, and the words came very queer indeed:-- + + `'Tis the voice of the Lobster; I heard him declare, + "You have baked me too brown, I must sugar my hair." + As a duck with its eyelids, so he with his nose + Trims his belt and his buttons, and turns out his toes.' + + [later editions continued as follows + When the sands are all dry, he is gay as a lark, + And will talk in contemptuous tones of the Shark, + But, when the tide rises and sharks are around, + His voice has a timid and tremulous sound.] + + `That's different from what I used to say when I was a child,' +said the Gryphon. + + `Well, I never heard it before,' said the Mock Turtle; `but it +sounds uncommon nonsense.' + + Alice said nothing; she had sat down with her face in her +hands, wondering if anything would EVER happen in a natural way +again. + + `I should like to have it explained,' said the Mock Turtle. + + `She can't explain it,' said the Gryphon hastily. `Go on with +the next verse.' + + `But about his toes?' the Mock Turtle persisted. `How COULD +he turn them out with his nose, you know?' + + `It's the first position in dancing.' Alice said; but was +dreadfully puzzled by the whole thing, and longed to change the +subject. + + `Go on with the next verse,' the Gryphon repeated impatiently: +`it begins "I passed by his garden."' + + Alice did not dare to disobey, though she felt sure it would +all come wrong, and she went on in a trembling voice:-- + + `I passed by his garden, and marked, with one eye, + How the Owl and the Panther were sharing a pie--' + + [later editions continued as follows + The Panther took pie-crust, and gravy, and meat, + While the Owl had the dish as its share of the treat. + When the pie was all finished, the Owl, as a boon, + Was kindly permitted to pocket the spoon: + While the Panther received knife and fork with a growl, + And concluded the banquet--] + + `What IS the use of repeating all that stuff,' the Mock Turtle +interrupted, `if you don't explain it as you go on? It's by far +the most confusing thing I ever heard!' + + `Yes, I think you'd better leave off,' said the Gryphon: and +Alice was only too glad to do so. + + `Shall we try another figure of the Lobster Quadrille?' the +Gryphon went on. `Or would you like the Mock Turtle to sing you +a song?' + + `Oh, a song, please, if the Mock Turtle would be so kind,' +Alice replied, so eagerly that the Gryphon said, in a rather +offended tone, `Hm! No accounting for tastes! Sing her "Turtle +Soup," will you, old fellow?' + + The Mock Turtle sighed deeply, and began, in a voice sometimes +choked with sobs, to sing this:-- + + + `Beautiful Soup, so rich and green, + Waiting in a hot tureen! + Who for such dainties would not stoop? + Soup of the evening, beautiful Soup! + Soup of the evening, beautiful Soup! + Beau--ootiful Soo--oop! + Beau--ootiful Soo--oop! + Soo--oop of the e--e--evening, + Beautiful, beautiful Soup! + + `Beautiful Soup! Who cares for fish, + Game, or any other dish? + Who would not give all else for two p + ennyworth only of beautiful Soup? + Pennyworth only of beautiful Soup? + Beau--ootiful Soo--oop! + Beau--ootiful Soo--oop! + Soo--oop of the e--e--evening, + Beautiful, beauti--FUL SOUP!' + + `Chorus again!' cried the Gryphon, and the Mock Turtle had +just begun to repeat it, when a cry of `The trial's beginning!' +was heard in the distance. + + `Come on!' cried the Gryphon, and, taking Alice by the hand, +it hurried off, without waiting for the end of the song. + + `What trial is it?' Alice panted as she ran; but the Gryphon +only answered `Come on!' and ran the faster, while more and more +faintly came, carried on the breeze that followed them, the +melancholy words:-- + + `Soo--oop of the e--e--evening, + Beautiful, beautiful Soup!' + + + + CHAPTER XI + + Who Stole the Tarts? + + + The King and Queen of Hearts were seated on their throne when +they arrived, with a great crowd assembled about them--all sorts +of little birds and beasts, as well as the whole pack of cards: +the Knave was standing before them, in chains, with a soldier on +each side to guard him; and near the King was the White Rabbit, +with a trumpet in one hand, and a scroll of parchment in the +other. In the very middle of the court was a table, with a large +dish of tarts upon it: they looked so good, that it made Alice +quite hungry to look at them--`I wish they'd get the trial done,' +she thought, `and hand round the refreshments!' But there seemed +to be no chance of this, so she began looking at everything about +her, to pass away the time. + + Alice had never been in a court of justice before, but she had +read about them in books, and she was quite pleased to find that +she knew the name of nearly everything there. `That's the +judge,' she said to herself, `because of his great wig.' + + The judge, by the way, was the King; and as he wore his crown +over the wig, (look at the frontispiece if you want to see how he +did it,) he did not look at all comfortable, and it was certainly +not becoming. + + `And that's the jury-box,' thought Alice, `and those twelve +creatures,' (she was obliged to say `creatures,' you see, because +some of them were animals, and some were birds,) `I suppose they +are the jurors.' She said this last word two or three times over +to herself, being rather proud of it: for she thought, and +rightly too, that very few little girls of her age knew the +meaning of it at all. However, `jury-men' would have done just +as well. + + The twelve jurors were all writing very busily on slates. +`What are they doing?' Alice whispered to the Gryphon. `They +can't have anything to put down yet, before the trial's begun.' + + `They're putting down their names,' the Gryphon whispered in +reply, `for fear they should forget them before the end of the +trial.' + + `Stupid things!' Alice began in a loud, indignant voice, but +she stopped hastily, for the White Rabbit cried out, `Silence in +the court!' and the King put on his spectacles and looked +anxiously round, to make out who was talking. + + Alice could see, as well as if she were looking over their +shoulders, that all the jurors were writing down `stupid things!' +on their slates, and she could even make out that one of them +didn't know how to spell `stupid,' and that he had to ask his +neighbour to tell him. `A nice muddle their slates'll be in +before the trial's over!' thought Alice. + + One of the jurors had a pencil that squeaked. This of course, +Alice could not stand, and she went round the court and got +behind him, and very soon found an opportunity of taking it +away. She did it so quickly that the poor little juror (it was +Bill, the Lizard) could not make out at all what had become of +it; so, after hunting all about for it, he was obliged to write +with one finger for the rest of the day; and this was of very +little use, as it left no mark on the slate. + + `Herald, read the accusation!' said the King. + + On this the White Rabbit blew three blasts on the trumpet, and +then unrolled the parchment scroll, and read as follows:-- + + `The Queen of Hearts, she made some tarts, + All on a summer day: + The Knave of Hearts, he stole those tarts, + And took them quite away!' + + `Consider your verdict,' the King said to the jury. + + `Not yet, not yet!' the Rabbit hastily interrupted. `There's +a great deal to come before that!' + + `Call the first witness,' said the King; and the White Rabbit +blew three blasts on the trumpet, and called out, `First +witness!' + + The first witness was the Hatter. He came in with a teacup in +one hand and a piece of bread-and-butter in the other. `I beg +pardon, your Majesty,' he began, `for bringing these in: but I +hadn't quite finished my tea when I was sent for.' + + `You ought to have finished,' said the King. `When did you +begin?' + + The Hatter looked at the March Hare, who had followed him into +the court, arm-in-arm with the Dormouse. `Fourteenth of March, I +think it was,' he said. + + `Fifteenth,' said the March Hare. + + `Sixteenth,' added the Dormouse. + + `Write that down,' the King said to the jury, and the jury +eagerly wrote down all three dates on their slates, and then +added them up, and reduced the answer to shillings and pence. + + `Take off your hat,' the King said to the Hatter. + + `It isn't mine,' said the Hatter. + + `Stolen!' the King exclaimed, turning to the jury, who +instantly made a memorandum of the fact. + + `I keep them to sell,' the Hatter added as an explanation; +`I've none of my own. I'm a hatter.' + + Here the Queen put on her spectacles, and began staring at the +Hatter, who turned pale and fidgeted. + + `Give your evidence,' said the King; `and don't be nervous, or +I'll have you executed on the spot.' + + This did not seem to encourage the witness at all: he kept +shifting from one foot to the other, looking uneasily at the +Queen, and in his confusion he bit a large piece out of his +teacup instead of the bread-and-butter. + + Just at this moment Alice felt a very curious sensation, which +puzzled her a good deal until she made out what it was: she was +beginning to grow larger again, and she thought at first she +would get up and leave the court; but on second thoughts she +decided to remain where she was as long as there was room for +her. + + `I wish you wouldn't squeeze so.' said the Dormouse, who was +sitting next to her. `I can hardly breathe.' + + `I can't help it,' said Alice very meekly: `I'm growing.' + + `You've no right to grow here,' said the Dormouse. + + `Don't talk nonsense,' said Alice more boldly: `you know +you're growing too.' + + `Yes, but I grow at a reasonable pace,' said the Dormouse: +`not in that ridiculous fashion.' And he got up very sulkily +and crossed over to the other side of the court. + + All this time the Queen had never left off staring at the +Hatter, and, just as the Dormouse crossed the court, she said to +one of the officers of the court, `Bring me the list of the +singers in the last concert!' on which the wretched Hatter +trembled so, that he shook both his shoes off. + + `Give your evidence,' the King repeated angrily, `or I'll have +you executed, whether you're nervous or not.' + + `I'm a poor man, your Majesty,' the Hatter began, in a +trembling voice, `--and I hadn't begun my tea--not above a week +or so--and what with the bread-and-butter getting so thin--and +the twinkling of the tea--' + + `The twinkling of the what?' said the King. + + `It began with the tea,' the Hatter replied. + + `Of course twinkling begins with a T!' said the King sharply. +`Do you take me for a dunce? Go on!' + + `I'm a poor man,' the Hatter went on, `and most things +twinkled after that--only the March Hare said--' + + `I didn't!' the March Hare interrupted in a great hurry. + + `You did!' said the Hatter. + + `I deny it!' said the March Hare. + + `He denies it,' said the King: `leave out that part.' + + `Well, at any rate, the Dormouse said--' the Hatter went on, +looking anxiously round to see if he would deny it too: but the +Dormouse denied nothing, being fast asleep. + + `After that,' continued the Hatter, `I cut some more bread- +and-butter--' + + `But what did the Dormouse say?' one of the jury asked. + + `That I can't remember,' said the Hatter. + + `You MUST remember,' remarked the King, `or I'll have you +executed.' + + The miserable Hatter dropped his teacup and bread-and-butter, +and went down on one knee. `I'm a poor man, your Majesty,' he +began. + + `You're a very poor speaker,' said the King. + + Here one of the guinea-pigs cheered, and was immediately +suppressed by the officers of the court. (As that is rather a +hard word, I will just explain to you how it was done. They had +a large canvas bag, which tied up at the mouth with strings: +into this they slipped the guinea-pig, head first, and then sat +upon it.) + + `I'm glad I've seen that done,' thought Alice. `I've so often +read in the newspapers, at the end of trials, "There was some +attempts at applause, which was immediately suppressed by the +officers of the court," and I never understood what it meant +till now.' + + `If that's all you know about it, you may stand down,' +continued the King. + + `I can't go no lower,' said the Hatter: `I'm on the floor, as +it is.' + + `Then you may SIT down,' the King replied. + + Here the other guinea-pig cheered, and was suppressed. + + `Come, that finished the guinea-pigs!' thought Alice. `Now we +shall get on better.' + + `I'd rather finish my tea,' said the Hatter, with an anxious +look at the Queen, who was reading the list of singers. + + `You may go,' said the King, and the Hatter hurriedly left the +court, without even waiting to put his shoes on. + + `--and just take his head off outside,' the Queen added to one +of the officers: but the Hatter was out of sight before the +officer could get to the door. + + `Call the next witness!' said the King. + + The next witness was the Duchess's cook. She carried the +pepper-box in her hand, and Alice guessed who it was, even before +she got into the court, by the way the people near the door began +sneezing all at once. + + `Give your evidence,' said the King. + + `Shan't,' said the cook. + + The King looked anxiously at the White Rabbit, who said in a +low voice, `Your Majesty must cross-examine THIS witness.' + + `Well, if I must, I must,' the King said, with a melancholy +air, and, after folding his arms and frowning at the cook till +his eyes were nearly out of sight, he said in a deep voice, `What +are tarts made of?' + + `Pepper, mostly,' said the cook. + + `Treacle,' said a sleepy voice behind her. + + `Collar that Dormouse,' the Queen shrieked out. `Behead that +Dormouse! Turn that Dormouse out of court! Suppress him! Pinch +him! Off with his whiskers!' + + For some minutes the whole court was in confusion, getting the +Dormouse turned out, and, by the time they had settled down +again, the cook had disappeared. + + `Never mind!' said the King, with an air of great relief. +`Call the next witness.' And he added in an undertone to the +Queen, `Really, my dear, YOU must cross-examine the next witness. +It quite makes my forehead ache!' + + Alice watched the White Rabbit as he fumbled over the list, +feeling very curious to see what the next witness would be like, +`--for they haven't got much evidence YET,' she said to herself. +Imagine her surprise, when the White Rabbit read out, at the top +of his shrill little voice, the name `Alice!' + + + + CHAPTER XII + + Alice's Evidence + + + `Here!' cried Alice, quite forgetting in the flurry of the +moment how large she had grown in the last few minutes, and she +jumped up in such a hurry that she tipped over the jury-box with +the edge of her skirt, upsetting all the jurymen on to the heads +of the crowd below, and there they lay sprawling about, reminding +her very much of a globe of goldfish she had accidentally upset +the week before. + + `Oh, I BEG your pardon!' she exclaimed in a tone of great +dismay, and began picking them up again as quickly as she could, +for the accident of the goldfish kept running in her head, and +she had a vague sort of idea that they must be collected at once +and put back into the jury-box, or they would die. + + `The trial cannot proceed,' said the King in a very grave +voice, `until all the jurymen are back in their proper places-- +ALL,' he repeated with great emphasis, looking hard at Alice as +he said do. + + Alice looked at the jury-box, and saw that, in her haste, she +had put the Lizard in head downwards, and the poor little thing +was waving its tail about in a melancholy way, being quite unable +to move. She soon got it out again, and put it right; `not that +it signifies much,' she said to herself; `I should think it +would be QUITE as much use in the trial one way up as the other.' + + As soon as the jury had a little recovered from the shock of +being upset, and their slates and pencils had been found and +handed back to them, they set to work very diligently to write +out a history of the accident, all except the Lizard, who seemed +too much overcome to do anything but sit with its mouth open, +gazing up into the roof of the court. + + `What do you know about this business?' the King said to +Alice. + + `Nothing,' said Alice. + + `Nothing WHATEVER?' persisted the King. + + `Nothing whatever,' said Alice. + + `That's very important,' the King said, turning to the jury. +They were just beginning to write this down on their slates, when +the White Rabbit interrupted: `UNimportant, your Majesty means, +of course,' he said in a very respectful tone, but frowning and +making faces at him as he spoke. + + `UNimportant, of course, I meant,' the King hastily said, and +went on to himself in an undertone, `important--unimportant-- +unimportant--important--' as if he were trying which word +sounded best. + + Some of the jury wrote it down `important,' and some +`unimportant.' Alice could see this, as she was near enough to +look over their slates; `but it doesn't matter a bit,' she +thought to herself. + + At this moment the King, who had been for some time busily +writing in his note-book, cackled out `Silence!' and read out +from his book, `Rule Forty-two. ALL PERSONS MORE THAN A MILE +HIGH TO LEAVE THE COURT.' + + Everybody looked at Alice. + + `I'M not a mile high,' said Alice. + + `You are,' said the King. + + `Nearly two miles high,' added the Queen. + + `Well, I shan't go, at any rate,' said Alice: `besides, +that's not a regular rule: you invented it just now.' + + `It's the oldest rule in the book,' said the King. + + `Then it ought to be Number One,' said Alice. + + The King turned pale, and shut his note-book hastily. +`Consider your verdict,' he said to the jury, in a low, trembling +voice. + + `There's more evidence to come yet, please your Majesty,' said +the White Rabbit, jumping up in a great hurry; `this paper has +just been picked up.' + + `What's in it?' said the Queen. + + `I haven't opened it yet,' said the White Rabbit, `but it seems +to be a letter, written by the prisoner to--to somebody.' + + `It must have been that,' said the King, `unless it was +written to nobody, which isn't usual, you know.' + + `Who is it directed to?' said one of the jurymen. + + `It isn't directed at all,' said the White Rabbit; `in fact, +there's nothing written on the OUTSIDE.' He unfolded the paper +as he spoke, and added `It isn't a letter, after all: it's a set +of verses.' + + `Are they in the prisoner's handwriting?' asked another of +they jurymen. + + `No, they're not,' said the White Rabbit, `and that's the +queerest thing about it.' (The jury all looked puzzled.) + + `He must have imitated somebody else's hand,' said the King. +(The jury all brightened up again.) + + `Please your Majesty,' said the Knave, `I didn't write it, and +they can't prove I did: there's no name signed at the end.' + + `If you didn't sign it,' said the King, `that only makes the +matter worse. You MUST have meant some mischief, or else you'd +have signed your name like an honest man.' + + There was a general clapping of hands at this: it was the +first really clever thing the King had said that day. + + `That PROVES his guilt,' said the Queen. + + `It proves nothing of the sort!' said Alice. `Why, you don't +even know what they're about!' + + `Read them,' said the King. + + The White Rabbit put on his spectacles. `Where shall I begin, +please your Majesty?' he asked. + + `Begin at the beginning,' the King said gravely, `and go on +till you come to the end: then stop.' + + These were the verses the White Rabbit read:-- + + `They told me you had been to her, + And mentioned me to him: + She gave me a good character, + But said I could not swim. + + He sent them word I had not gone + (We know it to be true): + If she should push the matter on, + What would become of you? + + I gave her one, they gave him two, + You gave us three or more; + They all returned from him to you, + Though they were mine before. + + If I or she should chance to be + Involved in this affair, + He trusts to you to set them free, + Exactly as we were. + + My notion was that you had been + (Before she had this fit) + An obstacle that came between + Him, and ourselves, and it. + + Don't let him know she liked them best, + For this must ever be + A secret, kept from all the rest, + Between yourself and me.' + + `That's the most important piece of evidence we've heard yet,' +said the King, rubbing his hands; `so now let the jury--' + + `If any one of them can explain it,' said Alice, (she had +grown so large in the last few minutes that she wasn't a bit +afraid of interrupting him,) `I'll give him sixpence. _I_ don't +believe there's an atom of meaning in it.' + + The jury all wrote down on their slates, `SHE doesn't believe +there's an atom of meaning in it,' but none of them attempted to +explain the paper. + + `If there's no meaning in it,' said the King, `that saves a +world of trouble, you know, as we needn't try to find any. And +yet I don't know,' he went on, spreading out the verses on his +knee, and looking at them with one eye; `I seem to see some +meaning in them, after all. "--SAID I COULD NOT SWIM--" you +can't swim, can you?' he added, turning to the Knave. + + The Knave shook his head sadly. `Do I look like it?' he said. +(Which he certainly did NOT, being made entirely of cardboard.) + + `All right, so far,' said the King, and he went on muttering +over the verses to himself: `"WE KNOW IT TO BE TRUE--" that's +the jury, of course-- "I GAVE HER ONE, THEY GAVE HIM TWO--" why, +that must be what he did with the tarts, you know--' + + `But, it goes on "THEY ALL RETURNED FROM HIM TO YOU,"' said +Alice. + + `Why, there they are!' said the King triumphantly, pointing to +the tarts on the table. `Nothing can be clearer than THAT. +Then again--"BEFORE SHE HAD THIS FIT--" you never had fits, my +dear, I think?' he said to the Queen. + + `Never!' said the Queen furiously, throwing an inkstand at the +Lizard as she spoke. (The unfortunate little Bill had left off +writing on his slate with one finger, as he found it made no +mark; but he now hastily began again, using the ink, that was +trickling down his face, as long as it lasted.) + + `Then the words don't FIT you,' said the King, looking round +the court with a smile. There was a dead silence. + + `It's a pun!' the King added in an offended tone, and +everybody laughed, `Let the jury consider their verdict,' the +King said, for about the twentieth time that day. + + `No, no!' said the Queen. `Sentence first--verdict afterwards.' + + `Stuff and nonsense!' said Alice loudly. `The idea of having +the sentence first!' + + `Hold your tongue!' said the Queen, turning purple. + + `I won't!' said Alice. + + `Off with her head!' the Queen shouted at the top of her voice. +Nobody moved. + + `Who cares for you?' said Alice, (she had grown to her full +size by this time.) `You're nothing but a pack of cards!' + + At this the whole pack rose up into the air, and came flying +down upon her: she gave a little scream, half of fright and half +of anger, and tried to beat them off, and found herself lying on +the bank, with her head in the lap of her sister, who was gently +brushing away some dead leaves that had fluttered down from the +trees upon her face. + + `Wake up, Alice dear!' said her sister; `Why, what a long +sleep you've had!' + + `Oh, I've had such a curious dream!' said Alice, and she told +her sister, as well as she could remember them, all these strange +Adventures of hers that you have just been reading about; and +when she had finished, her sister kissed her, and said, `It WAS a +curious dream, dear, certainly: but now run in to your tea; it's +getting late.' So Alice got up and ran off, thinking while she +ran, as well she might, what a wonderful dream it had been. + + But her sister sat still just as she left her, leaning her +head on her hand, watching the setting sun, and thinking of +little Alice and all her wonderful Adventures, till she too began +dreaming after a fashion, and this was her dream:-- + + First, she dreamed of little Alice herself, and once again the +tiny hands were clasped upon her knee, and the bright eager eyes +were looking up into hers--she could hear the very tones of her +voice, and see that queer little toss of her head to keep back +the wandering hair that WOULD always get into her eyes--and +still as she listened, or seemed to listen, the whole place +around her became alive the strange creatures of her little +sister's dream. + + The long grass rustled at her feet as the White Rabbit hurried +by--the frightened Mouse splashed his way through the +neighbouring pool--she could hear the rattle of the teacups as +the March Hare and his friends shared their never-ending meal, +and the shrill voice of the Queen ordering off her unfortunate +guests to execution--once more the pig-baby was sneezing on the +Duchess's knee, while plates and dishes crashed around it--once +more the shriek of the Gryphon, the squeaking of the Lizard's +slate-pencil, and the choking of the suppressed guinea-pigs, +filled the air, mixed up with the distant sobs of the miserable +Mock Turtle. + + So she sat on, with closed eyes, and half believed herself in +Wonderland, though she knew she had but to open them again, and +all would change to dull reality--the grass would be only +rustling in the wind, and the pool rippling to the waving of the +reeds--the rattling teacups would change to tinkling sheep- +bells, and the Queen's shrill cries to the voice of the shepherd +boy--and the sneeze of the baby, the shriek of the Gryphon, and +all thy other queer noises, would change (she knew) to the +confused clamour of the busy farm-yard--while the lowing of the +cattle in the distance would take the place of the Mock Turtle's +heavy sobs. + + Lastly, she pictured to herself how this same little sister of +hers would, in the after-time, be herself a grown woman; and how +she would keep, through all her riper years, the simple and +loving heart of her childhood: and how she would gather about +her other little children, and make THEIR eyes bright and eager +with many a strange tale, perhaps even with the dream of +Wonderland of long ago: and how she would feel with all their +simple sorrows, and find a pleasure in all their simple joys, +remembering her own child-life, and the happy summer days. + + THE END + \ No newline at end of file diff --git a/chromium/third_party/snappy/src/testdata/asyoulik.txt b/chromium/third_party/snappy/src/testdata/asyoulik.txt new file mode 100644 index 00000000000..88dc7b60fe2 --- /dev/null +++ b/chromium/third_party/snappy/src/testdata/asyoulik.txt @@ -0,0 +1,4122 @@ + AS YOU LIKE IT + + + DRAMATIS PERSONAE + + +DUKE SENIOR living in banishment. + +DUKE FREDERICK his brother, an usurper of his dominions. + + +AMIENS | + | lords attending on the banished duke. +JAQUES | + + +LE BEAU a courtier attending upon Frederick. + +CHARLES wrestler to Frederick. + + +OLIVER | + | +JAQUES (JAQUES DE BOYS:) | sons of Sir Rowland de Boys. + | +ORLANDO | + + +ADAM | + | servants to Oliver. +DENNIS | + + +TOUCHSTONE a clown. + +SIR OLIVER MARTEXT a vicar. + + +CORIN | + | shepherds. +SILVIUS | + + +WILLIAM a country fellow in love with Audrey. + + A person representing HYMEN.

My brother Jaques he keeps at school, and + report speaks goldenly of his profit: for my part, + he keeps me rustically at home, or, to speak more + properly, stays me here at home unkept; for call you + that keeping for a gentleman of my birth, that + differs not from the stalling of an ox? His horses + are bred better; for, besides that they are fair + with their feeding, they are taught their manage, + and to that end riders dearly hired: but I, his + brother, gain nothing under him but growth; for the + which his animals on his dunghills are as much + bound to him as I. Besides this nothing that he so + plentifully gives me, the something that nature gave + me his countenance seems to take from me: he lets + me feed with his hinds, bars me the place of a + brother, and, as much as in him lies, mines my + gentility with my education.

I know + you are my eldest brother; and, in the gentle + condition of blood, you should so know me. The + courtesy of nations allows you my better, in that + you are the first-born; but the same tradition + takes not away my blood, were there twenty brothers + betwixt us: I have as much of my father in me as + you; albeit, I confess, your coming before me is + nearer to his reverence. + +OLIVER What, boy! + +ORLANDO Come, come, elder brother, you are too young in this. + +OLIVER Wilt thou lay hands on me, villain? + +ORLANDO I am no villain; I am the youngest son of Sir + Rowland de Boys; he was my father, and he is thrice + a villain that says such a father begot villains. + Wert thou not my brother, I would not take this hand + from thy throat till this other had pulled out thy + tongue for saying so: thou hast railed on thyself. + +ADAM Sweet masters, be patient: for your father's + remembrance, be at accord. + +OLIVER Let me go, I say. + +ORLANDO I will not, till I please: you shall hear me. My + father charged you in his will to give me good + education: you have trained me like a peasant, + obscuring and hiding from me all gentleman-like + qualities. The spirit of my father grows strong in + me, and I will no longer endure it: therefore allow + me such exercises as may become a gentleman, or + give me the poor allottery my father left me by + testament; with that I will go buy my fortunes. + +OLIVER And what wilt thou do? beg, when that is spent? + Well, sir, get you in: I will not long be troubled + with you; you shall have some part of your will: I + pray you, leave me. + +ORLANDO I will no further offend you than becomes me for my good. + +OLIVER Get you with him, you old dog. + +ADAM Is 'old dog' my reward?

She is at the court, and no + less beloved of her uncle than his own daughter; and + never two ladies loved as they do. + +OLIVER Where will the old duke live? + +CHARLES They say he is already in the forest of Arden, and + a many merry men with him; and there they live like + the old Robin Hood of England: they say many young + gentlemen flock to him every day, and fleet the time + carelessly, as they did in the golden world. + +OLIVER What, you wrestle to-morrow before the new duke? + +CHARLES Marry, do I, sir; and I came to acquaint you with a + matter. I am given, sir, secretly to understand + that your younger brother Orlando hath a disposition + to come in disguised against me to try a fall. + To-morrow, sir, I wrestle for my credit; and he that + escapes me without some broken limb shall acquit him + well. Your brother is but young and tender; and, + for your love, I would be loath to foil him, as I + must, for my own honour, if he come in: therefore, + out of my love to you, I came hither to acquaint you + withal, that either you might stay him from his + intendment or brook such disgrace well as he shall + run into, in that it is a thing of his own search + and altogether against my will. + +OLIVER Charles, I thank thee for thy love to me, which + thou shalt find I will most kindly requite. I had + myself notice of my brother's purpose herein and + have by underhand means laboured to dissuade him from + it, but he is resolute. I'll tell thee, Charles: + it is the stubbornest young fellow of France, full + of ambition, an envious emulator of every man's + good parts, a secret and villanous contriver against + me his natural brother: therefore use thy + discretion; I had as lief thou didst break his neck + as his finger. And thou wert best look to't; for if + thou dost him any slight disgrace or if he do not + mightily grace himself on thee, he will practise + against thee by poison, entrap thee by some + treacherous device and never leave thee till he + hath ta'en thy life by some indirect means or other; + for, I assure thee, and almost with tears I speak + it, there is not one so young and so villanous this + day living. I speak but brotherly of him; but + should I anatomize him to thee as he is, I must + blush and weep and thou must look pale and wonder. + +CHARLES I am heartily glad I came hither to you. If he come + to-morrow, I'll give him his payment: if ever he go + alone again, I'll never wrestle for prize more: and + so God keep your worship! + +OLIVER Farewell, good Charles. + + [Exit CHARLES] + + Now will I stir this gamester: I hope I shall see + an end of him; for my soul, yet I know not why, + hates nothing more than he. Yet he's gentle, never + schooled and yet learned, full of noble device, of + all sorts enchantingly beloved, and indeed so much + in the heart of the world, and especially of my own + people, who best know him, that I am altogether + misprised: but it shall not be so long; this + wrestler shall clear all: nothing remains but that + I kindle the boy thither; which now I'll go about. + + [Exit] + + + + + AS YOU LIKE IT + + +ACT I + + + +SCENE II Lawn before the Duke's palace. + + + [Enter CELIA and ROSALIND] + +CELIA I pray thee, Rosalind, sweet my coz, be merry. + +ROSALIND Dear Celia, I show more mirth than I am mistress of; + and would you yet I were merrier? Unless you could + teach me to forget a banished father, you must not + learn me how to remember any extraordinary pleasure. + +CELIA Herein I see thou lovest me not with the full weight + that I love thee. If my uncle, thy banished father, + had banished thy uncle, the duke my father, so thou + hadst been still with me, I could have taught my + love to take thy father for mine: so wouldst thou, + if the truth of thy love to me were so righteously + tempered as mine is to thee. + +ROSALIND Well, I will forget the condition of my estate, to + rejoice in yours. + +CELIA You know my father hath no child but I, nor none is + like to have: and, truly, when he dies, thou shalt + be his heir, for what he hath taken away from thy + father perforce, I will render thee again in + affection; by mine honour, I will; and when I break + that oath, let me turn monster: therefore, my + sweet Rose, my dear Rose, be merry. + +ROSALIND From henceforth I will, coz, and devise sports. Let + me see; what think you of falling in love? + +CELIA Marry, I prithee, do, to make sport withal: but + love no man in good earnest; nor no further in sport + neither than with safety of a pure blush thou mayst + in honour come off again. + +ROSALIND What shall be our sport, then? + +CELIA Let us sit and mock the good housewife Fortune from + her wheel, that her gifts may henceforth be bestowed equally. + +ROSALIND I would we could do so, for her benefits are + mightily misplaced, and the bountiful blind woman + doth most mistake in her gifts to women. + +CELIA 'Tis true; for those that she makes fair she scarce + makes honest, and those that she makes honest she + makes very ill-favouredly. + +ROSALIND Nay, now thou goest from Fortune's office to + Nature's: Fortune reigns in gifts of the world, + not in the lineaments of Nature. + + [Enter TOUCHSTONE] + +CELIA No? when Nature hath made a fair creature, may she + not by Fortune fall into the fire? Though Nature + hath given us wit to flout at Fortune, hath not + Fortune sent in this fool to cut off the argument? + +ROSALIND Indeed, there is Fortune too hard for Nature, when + Fortune makes Nature's natural the cutter-off of + Nature's wit. + +CELIA Peradventure this is not Fortune's work neither, but + Nature's; who perceiveth our natural wits too dull + to reason of such goddesses and hath sent this + natural for our whetstone; for always the dulness of + the fool is the whetstone of the wits. How now, + wit! whither wander you? + +TOUCHSTONE Mistress, you must come away to your father. + +CELIA Were you made the messenger? + +TOUCHSTONE No, by mine honour, but I was bid to come for you. + +ROSALIND Where learned you that oath, fool? + +TOUCHSTONE Of a certain knight that swore by his honour they + were good pancakes and swore by his honour the + mustard was naught: now I'll stand to it, the + pancakes were naught and the mustard was good, and + yet was not the knight forsworn. + +CELIA How prove you that, in the great heap of your + knowledge? + +ROSALIND Ay, marry, now unmuzzle your wisdom. + +TOUCHSTONE Stand you both forth now: stroke your chins, and + swear by your beards that I am a knave. + +CELIA By our beards, if we had them, thou art. + +TOUCHSTONE By my knavery, if I had it, then I were; but if you + swear by that that is not, you are not forsworn: no + more was this knight swearing by his honour, for he + never had any; or if he had, he had sworn it away + before ever he saw those pancakes or that mustard. + +CELIA Prithee, who is't that thou meanest? + +TOUCHSTONE One that old Frederick, your father, loves. + +CELIA My father's love is enough to honour him: enough! + speak no more of him; you'll be whipped for taxation + one of these days. + +TOUCHSTONE The more pity, that fools may not speak wisely what + wise men do foolishly. + +CELIA By my troth, thou sayest true; for since the little + wit that fools have was silenced, the little foolery + that wise men have makes a great show. Here comes + Monsieur Le Beau. + +ROSALIND With his mouth full of news. + +CELIA Which he will put on us, as pigeons feed their young. + +ROSALIND Then shall we be news-crammed. + +CELIA All the better; we shall be the more marketable. + + [Enter LE BEAU] + + Bon jour, Monsieur Le Beau: what's the news? + +LE BEAU Fair princess, you have lost much good sport. + +CELIA Sport! of what colour? + +LE BEAU What colour, madam! how shall I answer you? + +ROSALIND As wit and fortune will. + +TOUCHSTONE Or as the Destinies decree. + +CELIA Well said: that was laid on with a trowel. + +TOUCHSTONE Nay, if I keep not my rank,-- + +ROSALIND Thou losest thy old smell. + +LE BEAU You amaze me, ladies: I would have told you of good + wrestling, which you have lost the sight of. + +ROSALIND You tell us the manner of the wrestling. + +LE BEAU I will tell you the beginning; and, if it please + your ladyships, you may see the end; for the best is + yet to do; and here, where you are, they are coming + to perform it. + +CELIA Well, the beginning, that is dead and buried. + +LE BEAU There comes an old man and his three sons,-- + +CELIA I could match this beginning with an old tale. + +LE BEAU Three proper young men, of excellent growth and presence. + +ROSALIND With bills on their necks, 'Be it known unto all men + by these presents.' + +LE BEAU The eldest of the three wrestled with Charles, the + duke's wrestler; which Charles in a moment threw him + and broke three of his ribs, that there is little + hope of life in him: so he served the second, and + so the third. Yonder they lie; the poor old man, + their father, making such pitiful dole over them + that all the beholders take his part with weeping. + +ROSALIND Alas! + +TOUCHSTONE But what is the sport, monsieur, that the ladies + have lost? + +LE BEAU Why, this that I speak of. + +TOUCHSTONE Thus men may grow wiser every day: it is the first + time that ever I heard breaking of ribs was sport + for ladies. + +CELIA Or I, I promise thee. + +ROSALIND But is there any else longs to see this broken music + in his sides? is there yet another dotes upon + rib-breaking? Shall we see this wrestling, cousin? + +LE BEAU You must, if you stay here; for here is the place + appointed for the wrestling, and they are ready to + perform it. + +CELIA Yonder, sure, they are coming: let us now stay and see it. + + [Flourish. Enter DUKE FREDERICK, Lords, ORLANDO, + CHARLES, and Attendants] + +DUKE FREDERICK Come on: since the youth will not be entreated, his + own peril on his forwardness. + +ROSALIND Is yonder the man? + +LE BEAU Even he, madam. + +CELIA Alas, he is too young! yet he looks successfully. + +DUKE FREDERICK How now, daughter and cousin! are you crept hither + to see the wrestling? + +ROSALIND Ay, my liege, so please you give us leave. + +DUKE FREDERICK You will take little delight in it, I can tell you; + there is such odds in the man. In pity of the + challenger's youth I would fain dissuade him, but he + will not be entreated. Speak to him, ladies; see if + you can move him. + +CELIA Call him hither, good Monsieur Le Beau. + +DUKE FREDERICK Do so: I'll not be by. + +LE BEAU Monsieur the challenger, the princesses call for you. + +ORLANDO I attend them with all respect and duty. + +ROSALIND Young man, have you challenged Charles the wrestler? + +ORLANDO No, fair princess; he is the general challenger: I + come but in, as others do, to try with him the + strength of my youth. + +CELIA Young gentleman, your spirits are too bold for your + years. You have seen cruel proof of this man's + strength: if you saw yourself with your eyes or + knew yourself with your judgment, the fear of your + adventure would counsel you to a more equal + enterprise. We pray you, for your own sake, to + embrace your own safety and give over this attempt. + +ROSALIND Do, young sir; your reputation shall not therefore + be misprised: we will make it our suit to the duke + that the wrestling might not go forward. + +ORLANDO I beseech you, punish me not with your hard + thoughts; wherein I confess me much guilty, to deny + so fair and excellent ladies any thing. But let + your fair eyes and gentle wishes go with me to my + trial: wherein if I be foiled, there is but one + shamed that was never gracious; if killed, but one + dead that was willing to be so: I shall do my + friends no wrong, for I have none to lament me, the + world no injury, for in it I have nothing; only in + the world I fill up a place, which may be better + supplied when I have made it empty. + +ROSALIND The little strength that I have, I would it were with you. + +CELIA And mine, to eke out hers. + +ROSALIND Fare you well: pray heaven I be deceived in you! + +CELIA Your heart's desires be with you! + +CHARLES Come, where is this young gallant that is so + desirous to lie with his mother earth? + +ORLANDO Ready, sir; but his will hath in it a more modest working. + +DUKE FREDERICK You shall try but one fall. + +CHARLES No, I warrant your grace, you shall not entreat him + to a second, that have so mightily persuaded him + from a first. + +ORLANDO An you mean to mock me after, you should not have + mocked me before: but come your ways. + +ROSALIND Now Hercules be thy speed, young man! + +CELIA I would I were invisible, to catch the strong + fellow by the leg. + + [They wrestle] + +ROSALIND O excellent young man! + +CELIA If I had a thunderbolt in mine eye, I can tell who + should down. + + [Shout. CHARLES is thrown] + +DUKE FREDERICK No more, no more. + +ORLANDO Yes, I beseech your grace: I am not yet well breathed. + +DUKE FREDERICK How dost thou, Charles? + +LE BEAU He cannot speak, my lord. + +DUKE FREDERICK Bear him away. What is thy name, young man? + +ORLANDO Orlando, my liege; the youngest son of Sir Rowland de Boys. + +DUKE FREDERICK I would thou hadst been son to some man else: + The world esteem'd thy father honourable, + But I did find him still mine enemy: + Thou shouldst have better pleased me with this deed, + Hadst thou descended from another house. + But fare thee well; thou art a gallant youth: + I would thou hadst told me of another father. + + [Exeunt DUKE FREDERICK, train, and LE BEAU] + +CELIA Were I my father, coz, would I do this? + +ORLANDO I am more proud to be Sir Rowland's son, + His youngest son; and would not change that calling, + To be adopted heir to Frederick. + +ROSALIND My father loved Sir Rowland as his soul, + And all the world was of my father's mind: + Had I before known this young man his son, + I should have given him tears unto entreaties, + Ere he should thus have ventured. + +CELIA Gentle cousin, + Let us go thank him and encourage him: + My father's rough and envious disposition + Sticks me at heart. Sir, you have well deserved: + If you do keep your promises in love + But justly, as you have exceeded all promise, + Your mistress shall be happy. + +ROSALIND Gentleman, + + [Giving him a chain from her neck] + + Wear this for me, one out of suits with fortune, + That could give more, but that her hand lacks means. + Shall we go, coz? + +CELIA Ay. Fare you well, fair gentleman. + +ORLANDO Can I not say, I thank you? My better parts + Are all thrown down, and that which here stands up + Is but a quintain, a mere lifeless block. + +ROSALIND He calls us back: my pride fell with my fortunes; + I'll ask him what he would. Did you call, sir? + Sir, you have wrestled well and overthrown + More than your enemies. + +CELIA Will you go, coz? + +ROSALIND Have with you. Fare you well. + + [Exeunt ROSALIND and CELIA] + +ORLANDO What passion hangs these weights upon my tongue? + I cannot speak to her, yet she urged conference. + O poor Orlando, thou art overthrown! + Or Charles or something weaker masters thee. + + [Re-enter LE BEAU] + +LE BEAU Good sir, I do in friendship counsel you + To leave this place. Albeit you have deserved + High commendation, true applause and love, + Yet such is now the duke's condition + That he misconstrues all that you have done. + The duke is humorous; what he is indeed, + More suits you to conceive than I to speak of. + +ORLANDO I thank you, sir: and, pray you, tell me this: + Which of the two was daughter of the duke + That here was at the wrestling? + +LE BEAU Neither his daughter, if we judge by manners; + But yet indeed the lesser is his daughter + The other is daughter to the banish'd duke, + And here detain'd by her usurping uncle, + To keep his daughter company; whose loves + Are dearer than the natural bond of sisters. + But I can tell you that of late this duke + Hath ta'en displeasure 'gainst his gentle niece, + Grounded upon no other argument + But that the people praise her for her virtues + And pity her for her good father's sake; + And, on my life, his malice 'gainst the lady + Will suddenly break forth. Sir, fare you well: + Hereafter, in a better world than this, + I shall desire more love and knowledge of you. + +ORLANDO I rest much bounden to you: fare you well. + + [Exit LE BEAU] + + Thus must I from the smoke into the smother; + From tyrant duke unto a tyrant brother: + But heavenly Rosalind! + + [Exit] + + + + + AS YOU LIKE IT + + +ACT I + + + +SCENE III A room in the palace. + + + [Enter CELIA and ROSALIND] + +CELIA Why, cousin! why, Rosalind! Cupid have mercy! not a word? + +ROSALIND Not one to throw at a dog. + +CELIA No, thy words are too precious to be cast away upon + curs; throw some of them at me; come, lame me with reasons. + +ROSALIND Then there were two cousins laid up; when the one + should be lamed with reasons and the other mad + without any. + +CELIA But is all this for your father? + +ROSALIND No, some of it is for my child's father. O, how + full of briers is this working-day world! + +CELIA They are but burs, cousin, thrown upon thee in + holiday foolery: if we walk not in the trodden + paths our very petticoats will catch them. + +ROSALIND I could shake them off my coat: these burs are in my heart. + +CELIA Hem them away. + +ROSALIND I would try, if I could cry 'hem' and have him. + +CELIA Come, come, wrestle with thy affections. + +ROSALIND O, they take the part of a better wrestler than myself! + +CELIA O, a good wish upon you! you will try in time, in + despite of a fall. But, turning these jests out of + service, let us talk in good earnest: is it + possible, on such a sudden, you should fall into so + strong a liking with old Sir Rowland's youngest son? + +ROSALIND The duke my father loved his father dearly. + +CELIA Doth it therefore ensue that you should love his son + dearly?

In respect that it is solitary, I + like it very well; but in respect that it is + private, it is a very vile life. Now, in respect it + is in the fields, it pleaseth me well; but in + respect it is not in the court, it is tedious. As + is it a spare life, look you, it fits my humour well; + but as there is no more plenty in it, it goes much + against my stomach. Hast any philosophy in thee, shepherd? + +CORIN No more but that I know the more one sickens the + worse at ease he is; and that he that wants money, + means and content is without three good friends; + that the property of rain is to wet and fire to + burn; that good pasture makes fat sheep, and that a + great cause of the night is lack of the sun; that + he that hath learned no wit by nature nor art may + complain of good breeding or comes of a very dull kindred. + +TOUCHSTONE Such a one is a natural philosopher. Wast ever in + court, shepherd? + +CORIN No, truly. + +TOUCHSTONE Then thou art damned. + +CORIN Nay, I hope. + +TOUCHSTONE Truly, thou art damned like an ill-roasted egg, all + on one side. + +CORIN For not being at court? Your reason. + +TOUCHSTONE Why, if thou never wast at court, thou never sawest + good manners; if thou never sawest good manners, + then thy manners must be wicked; and wickedness is + sin, and sin is damnation. Thou art in a parlous + state, shepherd. + +CORIN Not a whit, Touchstone: those that are good manners + at the court are as ridiculous in the country as the + behavior of the country is most mockable at the + court. You told me you salute not at the court, but + you kiss your hands: that courtesy would be + uncleanly, if courtiers were shepherds. + +TOUCHSTONE Instance, briefly; come, instance. + +CORIN Why, we are still handling our ewes, and their + fells, you know, are greasy. + +TOUCHSTONE Why, do not your courtier's hands sweat? and is not + the grease of a mutton as wholesome as the sweat of + a man? Shallow, shallow. A better instance, I say; come. + +CORIN Besides, our hands are hard. + +TOUCHSTONE Your lips will feel them the sooner. Shallow again. + A more sounder instance, come. + +CORIN And they are often tarred over with the surgery of + our sheep: and would you have us kiss tar? The + courtier's hands are perfumed with civet. + +TOUCHSTONE Most shallow man! thou worms-meat, in respect of a + good piece of flesh indeed! Learn of the wise, and + perpend: civet is of a baser birth than tar, the + very uncleanly flux of a cat. Mend the instance, shepherd. + +CORIN You have too courtly a wit for me: I'll rest. + +TOUCHSTONE Wilt thou rest damned? God help thee, shallow man! + God make incision in thee! thou art raw. + +CORIN Sir, I am a true labourer: I earn that I eat, get + that I wear, owe no man hate, envy no man's + happiness, glad of other men's good, content with my + harm, and the greatest of my pride is to see my ewes + graze and my lambs suck. + +TOUCHSTONE That is another simple sin in you, to bring the ewes + and the rams together and to offer to get your + living by the copulation of cattle; to be bawd to a + bell-wether, and to betray a she-lamb of a + twelvemonth to a crooked-pated, old, cuckoldly ram, + out of all reasonable match. If thou beest not + damned for this, the devil himself will have no + shepherds; I cannot see else how thou shouldst + 'scape. + +CORIN Here comes young Master Ganymede, my new mistress's brother. + + [Enter ROSALIND, with a paper, reading] + +ROSALIND From the east to western Ind, + No jewel is like Rosalind. + Her worth, being mounted on the wind, + Through all the world bears Rosalind. + All the pictures fairest lined + Are but black to Rosalind. + Let no fair be kept in mind + But the fair of Rosalind. + +TOUCHSTONE I'll rhyme you so eight years together, dinners and + suppers and sleeping-hours excepted: it is the + right butter-women's rank to market. + +ROSALIND Out, fool! + +TOUCHSTONE For a taste: + If a hart do lack a hind, + Let him seek out Rosalind. + If the cat will after kind, + So be sure will Rosalind. + Winter garments must be lined, + So must slender Rosalind. + They that reap must sheaf and bind; + Then to cart with Rosalind. + Sweetest nut hath sourest rind, + Such a nut is Rosalind. + He that sweetest rose will find + Must find love's prick and Rosalind. + This is the very false gallop of verses: why do you + infect yourself with them? + +ROSALIND Peace, you dull fool! I found them on a tree. + +TOUCHSTONE Truly, the tree yields bad fruit. + +ROSALIND I'll graff it with you, and then I shall graff it + with a medlar: then it will be the earliest fruit + i' the country; for you'll be rotten ere you be half + ripe, and that's the right virtue of the medlar. + +TOUCHSTONE You have said; but whether wisely or no, let the + forest judge. + + [Enter CELIA, with a writing] + +ROSALIND Peace! Here comes my sister, reading: stand aside. + +CELIA [Reads] + + Why should this a desert be? + For it is unpeopled? No: + Tongues I'll hang on every tree, + That shall civil sayings show: + Some, how brief the life of man + Runs his erring pilgrimage, + That the stretching of a span + Buckles in his sum of age; + Some, of violated vows + 'Twixt the souls of friend and friend: + But upon the fairest boughs, + Or at every sentence end, + Will I Rosalinda write, + Teaching all that read to know + The quintessence of every sprite + Heaven would in little show. + Therefore Heaven Nature charged + That one body should be fill'd + With all graces wide-enlarged: + Nature presently distill'd + Helen's cheek, but not her heart, + Cleopatra's majesty, + Atalanta's better part, + Sad Lucretia's modesty. + Thus Rosalind of many parts + By heavenly synod was devised, + Of many faces, eyes and hearts, + To have the touches dearest prized. + Heaven would that she these gifts should have, + And I to live and die her slave. + +ROSALIND O most gentle pulpiter! what tedious homily of love + have you wearied your parishioners withal, and never + cried 'Have patience, good people!' + +CELIA How now! back, friends! Shepherd, go off a little. + Go with him, sirrah. + +TOUCHSTONE Come, shepherd, let us make an honourable retreat; + though not with bag and baggage, yet with scrip and scrippage. + + [Exeunt CORIN and TOUCHSTONE] + +CELIA Didst thou hear these verses? + +ROSALIND O, yes, I heard them all, and more too; for some of + them had in them more feet than the verses would bear. + +CELIA That's no matter: the feet might bear the verses. + +ROSALIND Ay, but the feet were lame and could not bear + themselves without the verse and therefore stood + lamely in the verse. + +CELIA But didst thou hear without wondering how thy name + should be hanged and carved upon these trees? + +ROSALIND I was seven of the nine days out of the wonder + before you came; for look here what I found on a + palm-tree. I was never so be-rhymed since + Pythagoras' time, that I was an Irish rat, which I + can hardly remember. + +CELIA Trow you who hath done this? + +ROSALIND Is it a man? + +CELIA And a chain, that you once wore, about his neck. + Change you colour? + +ROSALIND I prithee, who? + +CELIA O Lord, Lord! it is a hard matter for friends to + meet; but mountains may be removed with earthquakes + and so encounter. + +ROSALIND Nay, but who is it? + +CELIA Is it possible? + +ROSALIND Nay, I prithee now with most petitionary vehemence, + tell me who it is. + +CELIA O wonderful, wonderful, and most wonderful + wonderful! and yet again wonderful, and after that, + out of all hooping! + +ROSALIND Good my complexion! dost thou think, though I am + caparisoned like a man, I have a doublet and hose in + my disposition? One inch of delay more is a + South-sea of discovery; I prithee, tell me who is it + quickly, and speak apace. I would thou couldst + stammer, that thou mightst pour this concealed man + out of thy mouth, as wine comes out of a narrow- + mouthed bottle, either too much at once, or none at + all. I prithee, take the cork out of thy mouth that + may drink thy tidings. + +CELIA So you may put a man in your belly. + +ROSALIND Is he of God's making? What manner of man? Is his + head worth a hat, or his chin worth a beard? + +CELIA Nay, he hath but a little beard. + +ROSALIND Why, God will send more, if the man will be + thankful: let me stay the growth of his beard, if + thou delay me not the knowledge of his chin. + +CELIA It is young Orlando, that tripped up the wrestler's + heels and your heart both in an instant. + +ROSALIND Nay, but the devil take mocking: speak, sad brow and + true maid. + +CELIA I' faith, coz, 'tis he. + +ROSALIND Orlando? + +CELIA Orlando. + +ROSALIND Alas the day! what shall I do with my doublet and + hose? What did he when thou sawest him? What said + he? How looked he? Wherein went he? What makes + him here? Did he ask for me? Where remains he? + How parted he with thee? and when shalt thou see + him again? Answer me in one word. + +CELIA You must borrow me Gargantua's mouth first: 'tis a + word too great for any mouth of this age's size. To + say ay and no to these particulars is more than to + answer in a catechism. + +ROSALIND But doth he know that I am in this forest and in + man's apparel? Looks he as freshly as he did the + day he wrestled? + +CELIA It is as easy to count atomies as to resolve the + propositions of a lover; but take a taste of my + finding him, and relish it with good observance. + I found him under a tree, like a dropped acorn. + +ROSALIND It may well be called Jove's tree, when it drops + forth such fruit. + +CELIA Give me audience, good madam. + +ROSALIND Proceed. + +CELIA There lay he, stretched along, like a wounded knight. + +ROSALIND Though it be pity to see such a sight, it well + becomes the ground. + +CELIA Cry 'holla' to thy tongue, I prithee; it curvets + unseasonably. He was furnished like a hunter. + +ROSALIND O, ominous! he comes to kill my heart. + +CELIA I would sing my song without a burden: thou bringest + me out of tune. + +ROSALIND Do you not know I am a woman? when I think, I must + speak. Sweet, say on. + +CELIA You bring me out. Soft! comes he not here? + + [Enter ORLANDO and JAQUES] + +ROSALIND 'Tis he: slink by, and note him. + +JAQUES I thank you for your company; but, good faith, I had + as lief have been myself alone. + +ORLANDO And so had I; but yet, for fashion sake, I thank you + too for your society. + +JAQUES God be wi' you: let's meet as little as we can. + +ORLANDO I do desire we may be better strangers. + +JAQUES I pray you, mar no more trees with writing + love-songs in their barks. + +ORLANDO I pray you, mar no more of my verses with reading + them ill-favouredly. + +JAQUES Rosalind is your love's name? + +ORLANDO Yes, just. + +JAQUES I do not like her name. + +ORLANDO There was no thought of pleasing you when she was + christened. + +JAQUES What stature is she of? + +ORLANDO Just as high as my heart. + +JAQUES You are full of pretty answers. Have you not been + acquainted with goldsmiths' wives, and conned them + out of rings? + +ORLANDO Not so; but I answer you right painted cloth, from + whence you have studied your questions. + +JAQUES You have a nimble wit: I think 'twas made of + Atalanta's heels. Will you sit down with me? and + we two will rail against our mistress the world and + all our misery. + +ORLANDO I will chide no breather in the world but myself, + against whom I know most faults. + +JAQUES The worst fault you have is to be in love. + +ORLANDO 'Tis a fault I will not change for your best virtue. + I am weary of you. + +JAQUES By my troth, I was seeking for a fool when I found + you. + +ORLANDO He is drowned in the brook: look but in, and you + shall see him. + +JAQUES There I shall see mine own figure. + +ORLANDO Which I take to be either a fool or a cipher. + +JAQUES I'll tarry no longer with you: farewell, good + Signior Love. + +ORLANDO I am glad of your departure: adieu, good Monsieur + Melancholy. + + [Exit JAQUES] + +ROSALIND [Aside to CELIA] I will speak to him, like a saucy + lackey and under that habit play the knave with him. + Do you hear, forester? + +ORLANDO Very well: what would you? + +ROSALIND I pray you, what is't o'clock? + +ORLANDO You should ask me what time o' day: there's no clock + in the forest. + +ROSALIND Then there is no true lover in the forest; else + sighing every minute and groaning every hour would + detect the lazy foot of Time as well as a clock. + +ORLANDO And why not the swift foot of Time? had not that + been as proper? + +ROSALIND By no means, sir: Time travels in divers paces with + divers persons. I'll tell you who Time ambles + withal, who Time trots withal, who Time gallops + withal and who he stands still withal. + +ORLANDO I prithee, who doth he trot withal? + +ROSALIND Marry, he trots hard with a young maid between the + contract of her marriage and the day it is + solemnized: if the interim be but a se'nnight, + Time's pace is so hard that it seems the length of + seven year. + +ORLANDO Who ambles Time withal? + +ROSALIND With a priest that lacks Latin and a rich man that + hath not the gout, for the one sleeps easily because + he cannot study, and the other lives merrily because + he feels no pain, the one lacking the burden of lean + and wasteful learning, the other knowing no burden + of heavy tedious penury; these Time ambles withal. + +ORLANDO Who doth he gallop withal? + +ROSALIND With a thief to the gallows, for though he go as + softly as foot can fall, he thinks himself too soon there. + +ORLANDO Who stays it still withal? + +ROSALIND With lawyers in the vacation, for they sleep between + term and term and then they perceive not how Time moves. + +ORLANDO Where dwell you, pretty youth? + +ROSALIND With this shepherdess, my sister; here in the + skirts of the forest, like fringe upon a petticoat. + +ORLANDO Are you native of this place? + +ROSALIND As the cony that you see dwell where she is kindled. + +ORLANDO Your accent is something finer than you could + purchase in so removed a dwelling. + +ROSALIND I have been told so of many: but indeed an old + religious uncle of mine taught me to speak, who was + in his youth an inland man; one that knew courtship + too well, for there he fell in love. I have heard + him read many lectures against it, and I thank God + I am not a woman, to be touched with so many + giddy offences as he hath generally taxed their + whole sex withal. + +ORLANDO Can you remember any of the principal evils that he + laid to the charge of women? + +ROSALIND There were none principal; they were all like one + another as half-pence are, every one fault seeming + monstrous till his fellow fault came to match it. + +ORLANDO I prithee, recount some of them. + +ROSALIND No, I will not cast away my physic but on those that + are sick. There is a man haunts the forest, that + abuses our young plants with carving 'Rosalind' on + their barks; hangs odes upon hawthorns and elegies + on brambles, all, forsooth, deifying the name of + Rosalind: if I could meet that fancy-monger I would + give him some good counsel, for he seems to have the + quotidian of love upon him. + +ORLANDO I am he that is so love-shaked: I pray you tell me + your remedy. + +ROSALIND There is none of my uncle's marks upon you: he + taught me how to know a man in love; in which cage + of rushes I am sure you are not prisoner. + +ORLANDO What were his marks? + +ROSALIND A lean cheek, which you have not, a blue eye and + sunken, which you have not, an unquestionable + spirit, which you have not, a beard neglected, + which you have not; but I pardon you for that, for + simply your having in beard is a younger brother's + revenue: then your hose should be ungartered, your + bonnet unbanded, your sleeve unbuttoned, your shoe + untied and every thing about you demonstrating a + careless desolation; but you are no such man; you + are rather point-device in your accoutrements as + loving yourself than seeming the lover of any other. + +ORLANDO Fair youth, I would I could make thee believe I love. + +ROSALIND Me believe it! you may as soon make her that you + love believe it; which, I warrant, she is apter to + do than to confess she does: that is one of the + points in the which women still give the lie to + their consciences. But, in good sooth, are you he + that hangs the verses on the trees, wherein Rosalind + is so admired? + +ORLANDO I swear to thee, youth, by the white hand of + Rosalind, I am that he, that unfortunate he. + +ROSALIND But are you so much in love as your rhymes speak? + +ORLANDO Neither rhyme nor reason can express how much. + +ROSALIND Love is merely a madness, and, I tell you, deserves + as well a dark house and a whip as madmen do: and + the reason why they are not so punished and cured + is, that the lunacy is so ordinary that the whippers + are in love too. Yet I profess curing it by counsel. + +ORLANDO Did you ever cure any so? + +ROSALIND Yes, one, and in this manner. He was to imagine me + his love, his mistress; and I set him every day to + woo me: at which time would I, being but a moonish + youth, grieve, be effeminate, changeable, longing + and liking, proud, fantastical, apish, shallow, + inconstant, full of tears, full of smiles, for every + passion something and for no passion truly any + thing, as boys and women are for the most part + cattle of this colour; would now like him, now loathe + him; then entertain him, then forswear him; now weep + for him, then spit at him; that I drave my suitor + from his mad humour of love to a living humour of + madness; which was, to forswear the full stream of + the world, and to live in a nook merely monastic. + And thus I cured him; and this way will I take upon + me to wash your liver as clean as a sound sheep's + heart, that there shall not be one spot of love in't. + +ORLANDO I would not be cured, youth. + +ROSALIND I would cure you, if you would but call me Rosalind + and come every day to my cote and woo me. + +ORLANDO Now, by the faith of my love, I will: tell me + where it is. + +ROSALIND Go with me to it and I'll show it you and by the way + you shall tell me where in the forest you live. + Will you go? + +ORLANDO With all my heart, good youth. + +ROSALIND Nay you must call me Rosalind. Come, sister, will you go? + + [Exeunt] + + + + + AS YOU LIKE IT + + +ACT III + + + +SCENE III The forest. + + + [Enter TOUCHSTONE and AUDREY; JAQUES behind] + +TOUCHSTONE Come apace, good Audrey: I will fetch up your + goats, Audrey. And how, Audrey? am I the man yet? + doth my simple feature content you? + +AUDREY Your features! Lord warrant us! what features! + +TOUCHSTONE I am here with thee and thy goats, as the most + capricious poet, honest Ovid, was among the Goths. + +JAQUES [Aside] O knowledge ill-inhabited, worse than Jove + in a thatched house! + +TOUCHSTONE When a man's verses cannot be understood, nor a + man's good wit seconded with the forward child + Understanding, it strikes a man more dead than a + great reckoning in a little room. Truly, I would + the gods had made thee poetical. + +AUDREY I do not know what 'poetical' is: is it honest in + deed and word? is it a true thing? + +TOUCHSTONE No, truly; for the truest poetry is the most + feigning; and lovers are given to poetry, and what + they swear in poetry may be said as lovers they do feign. + +AUDREY Do you wish then that the gods had made me poetical? + +TOUCHSTONE I do, truly; for thou swearest to me thou art + honest: now, if thou wert a poet, I might have some + hope thou didst feign. + +AUDREY Would you not have me honest? + +TOUCHSTONE No, truly, unless thou wert hard-favoured; for + honesty coupled to beauty is to have honey a sauce to sugar. + +JAQUES [Aside] A material fool! + +AUDREY Well, I am not fair; and therefore I pray the gods + make me honest. + +TOUCHSTONE Truly, and to cast away honesty upon a foul slut + were to put good meat into an unclean dish. + +AUDREY I am not a slut, though I thank the gods I am foul. + +TOUCHSTONE Well, praised be the gods for thy foulness! + sluttishness may come hereafter. But be it as it may + be, I will marry thee, and to that end I have been + with Sir Oliver Martext, the vicar of the next + village, who hath promised to meet me in this place + of the forest and to couple us. + +JAQUES [Aside] I would fain see this meeting. + +AUDREY Well, the gods give us joy! + +TOUCHSTONE Amen. A man may, if he were of a fearful heart, + stagger in this attempt; for here we have no temple + but the wood, no assembly but horn-beasts. But what + though? Courage! As horns are odious, they are + necessary. It is said, 'many a man knows no end of + his goods:' right; many a man has good horns, and + knows no end of them. Well, that is the dowry of + his wife; 'tis none of his own getting. Horns? + Even so. Poor men alone? No, no; the noblest deer + hath them as huge as the rascal. Is the single man + therefore blessed? No: as a walled town is more + worthier than a village, so is the forehead of a + married man more honourable than the bare brow of a + bachelor; and by how much defence is better than no + skill, by so much is a horn more precious than to + want. Here comes Sir Oliver. + + [Enter SIR OLIVER MARTEXT] + + Sir Oliver Martext, you are well met: will you + dispatch us here under this tree, or shall we go + with you to your chapel? + +SIR OLIVER MARTEXT Is there none here to give the woman? + +TOUCHSTONE I will not take her on gift of any man. + +SIR OLIVER MARTEXT Truly, she must be given, or the marriage is not lawful. + +JAQUES [Advancing] + + Proceed, proceed I'll give her. + +TOUCHSTONE Good even, good Master What-ye-call't: how do you, + sir? You are very well met: God 'ild you for your + last company: I am very glad to see you: even a + toy in hand here, sir: nay, pray be covered. + +JAQUES Will you be married, motley? + +TOUCHSTONE As the ox hath his bow, sir, the horse his curb and + the falcon her bells, so man hath his desires; and + as pigeons bill, so wedlock would be nibbling. + +JAQUES And will you, being a man of your breeding, be + married under a bush like a beggar? Get you to + church, and have a good priest that can tell you + what marriage is: this fellow will but join you + together as they join wainscot; then one of you will + prove a shrunk panel and, like green timber, warp, warp. + +TOUCHSTONE [Aside] I am not in the mind but I were better to be + married of him than of another: for he is not like + to marry me well; and not being well married, it + will be a good excuse for me hereafter to leave my wife. + +JAQUES Go thou with me, and let me counsel thee. + +TOUCHSTONE 'Come, sweet Audrey: + We must be married, or we must live in bawdry. + Farewell, good Master Oliver: not,-- + O sweet Oliver, + O brave Oliver, + Leave me not behind thee: but,-- + Wind away, + Begone, I say, + I will not to wedding with thee. + + [Exeunt JAQUES, TOUCHSTONE and AUDREY] + +SIR OLIVER MARTEXT 'Tis no matter: ne'er a fantastical knave of them + all shall flout me out of my calling. + + [Exit] + + + + + AS YOU LIKE IT + + +ACT III + + + +SCENE IV The forest. + + + [Enter ROSALIND and CELIA] + +ROSALIND Never talk to me; I will weep. + +CELIA Do, I prithee; but yet have the grace to consider + that tears do not become a man. + +ROSALIND But have I not cause to weep? + +CELIA As good cause as one would desire; therefore weep. + +ROSALIND His very hair is of the dissembling colour. + +CELIA Something browner than Judas's marry, his kisses are + Judas's own children. + +ROSALIND I' faith, his hair is of a good colour. + +CELIA An excellent colour: your chestnut was ever the only colour. + +ROSALIND And his kissing is as full of sanctity as the touch + of holy bread. + +CELIA He hath bought a pair of cast lips of Diana: a nun + of winter's sisterhood kisses not more religiously; + the very ice of chastity is in them. + +ROSALIND But why did he swear he would come this morning, and + comes not? + +CELIA Nay, certainly, there is no truth in him. + +ROSALIND Do you think so? + +CELIA Yes; I think he is not a pick-purse nor a + horse-stealer, but for his verity in love, I do + think him as concave as a covered goblet or a + worm-eaten nut. + +ROSALIND Not true in love? + +CELIA Yes, when he is in; but I think he is not in. + +ROSALIND You have heard him swear downright he was. + +CELIA 'Was' is not 'is:' besides, the oath of a lover is + no stronger than the word of a tapster; they are + both the confirmer of false reckonings. He attends + here in the forest on the duke your father. + +ROSALIND I met the duke yesterday and had much question with + him: he asked me of what parentage I was; I told + him, of as good as he; so he laughed and let me go. + But what talk we of fathers, when there is such a + man as Orlando? + +CELIA O, that's a brave man! he writes brave verses, + speaks brave words, swears brave oaths and breaks + them bravely, quite traverse, athwart the heart of + his lover; as a puisny tilter, that spurs his horse + but on one side, breaks his staff like a noble + goose: but all's brave that youth mounts and folly + guides.

The common executioner, + Whose heart the accustom'd sight of death makes hard, + Falls not the axe upon the humbled neck + But first begs pardon: will you sterner be + Than he that dies and lives by bloody drops? + + [Enter ROSALIND, CELIA, and CORIN, behind] + +PHEBE I would not be thy executioner: + I fly thee, for I would not injure thee. + Thou tell'st me there is murder in mine eye: + 'Tis pretty, sure, and very probable, + That eyes, that are the frail'st and softest things, + Who shut their coward gates on atomies, + Should be call'd tyrants, butchers, murderers! + Now I do frown on thee with all my heart; + And if mine eyes can wound, now let them kill thee: + Now counterfeit to swoon; why now fall down; + Or if thou canst not, O, for shame, for shame, + Lie not, to say mine eyes are murderers! + Now show the wound mine eye hath made in thee: + Scratch thee but with a pin, and there remains + Some scar of it; lean but upon a rush, + The cicatrice and capable impressure + Thy palm some moment keeps; but now mine eyes, + Which I have darted at thee, hurt thee not, + Nor, I am sure, there is no force in eyes + That can do hurt. + +SILVIUS O dear Phebe, + If ever,--as that ever may be near,-- + You meet in some fresh cheek the power of fancy, + Then shall you know the wounds invisible + That love's keen arrows make. + +PHEBE But till that time + Come not thou near me: and when that time comes, + Afflict me with thy mocks, pity me not; + As till that time I shall not pity thee. + +ROSALIND And why, I pray you? Who might be your mother, + That you insult, exult, and all at once, + Over the wretched? What though you have no beauty,-- + As, by my faith, I see no more in you + Than without candle may go dark to bed-- + Must you be therefore proud and pitiless? + Why, what means this? Why do you look on me? + I see no more in you than in the ordinary + Of nature's sale-work. 'Od's my little life, + I think she means to tangle my eyes too! + No, faith, proud mistress, hope not after it: + 'Tis not your inky brows, your black silk hair, + Your bugle eyeballs, nor your cheek of cream, + That can entame my spirits to your worship. + You foolish shepherd, wherefore do you follow her, + Like foggy south puffing with wind and rain? + You are a thousand times a properer man + Than she a woman: 'tis such fools as you + That makes the world full of ill-favour'd children: + 'Tis not her glass, but you, that flatters her; + And out of you she sees herself more proper + Than any of her lineaments can show her. + But, mistress, know yourself: down on your knees, + And thank heaven, fasting, for a good man's love: + For I must tell you friendly in your ear, + Sell when you can: you are not for all markets: + Cry the man mercy; love him; take his offer: + Foul is most foul, being foul to be a scoffer. + So take her to thee, shepherd: fare you well. + +PHEBE Sweet youth, I pray you, chide a year together: + I had rather hear you chide than this man woo. + +ROSALIND He's fallen in love with your foulness and she'll + fall in love with my anger. If it be so, as fast as + she answers thee with frowning looks, I'll sauce her + with bitter words. Why look you so upon me? + +PHEBE For no ill will I bear you. + +ROSALIND I pray you, do not fall in love with me, + For I am falser than vows made in wine: + Besides, I like you not. If you will know my house, + 'Tis at the tuft of olives here hard by. + Will you go, sister? Shepherd, ply her hard. + Come, sister. Shepherdess, look on him better, + And be not proud: though all the world could see, + None could be so abused in sight as he. + Come, to our flock. + + [Exeunt ROSALIND, CELIA and CORIN] + +PHEBE Dead Shepherd, now I find thy saw of might, + 'Who ever loved that loved not at first sight?' + +SILVIUS Sweet Phebe,-- + +PHEBE Ha, what say'st thou, Silvius? + +SILVIUS Sweet Phebe, pity me. + +PHEBE Why, I am sorry for thee, gentle Silvius. + +SILVIUS Wherever sorrow is, relief would be: + If you do sorrow at my grief in love, + By giving love your sorrow and my grief + Were both extermined. + +PHEBE Thou hast my love: is not that neighbourly? + +SILVIUS I would have you. + +PHEBE Why, that were covetousness. + Silvius, the time was that I hated thee, + And yet it is not that I bear thee love; + But since that thou canst talk of love so well, + Thy company, which erst was irksome to me, + I will endure, and I'll employ thee too: + But do not look for further recompense + Than thine own gladness that thou art employ'd. + +SILVIUS So holy and so perfect is my love, + And I in such a poverty of grace, + That I shall think it a most plenteous crop + To glean the broken ears after the man + That the main harvest reaps: loose now and then + A scatter'd smile, and that I'll live upon. + +PHEBE Know'st now the youth that spoke to me erewhile? + +SILVIUS Not very well, but I have met him oft; + And he hath bought the cottage and the bounds + That the old carlot once was master of. + +PHEBE Think not I love him, though I ask for him: + 'Tis but a peevish boy; yet he talks well; + But what care I for words? yet words do well + When he that speaks them pleases those that hear. + It is a pretty youth: not very pretty: + But, sure, he's proud, and yet his pride becomes him: + He'll make a proper man: the best thing in him + Is his complexion; and faster than his tongue + Did make offence his eye did heal it up. + He is not very tall; yet for his years he's tall: + His leg is but so so; and yet 'tis well: + There was a pretty redness in his lip, + A little riper and more lusty red + Than that mix'd in his cheek; 'twas just the difference + Between the constant red and mingled damask. + There be some women, Silvius, had they mark'd him + In parcels as I did, would have gone near + To fall in love with him; but, for my part, + I love him not nor hate him not; and yet + I have more cause to hate him than to love him: + For what had he to do to chide at me? + He said mine eyes were black and my hair black: + And, now I am remember'd, scorn'd at me: + I marvel why I answer'd not again: + But that's all one; omittance is no quittance. + I'll write to him a very taunting letter, + And thou shalt bear it: wilt thou, Silvius? + +SILVIUS Phebe, with all my heart. + +PHEBE I'll write it straight; + The matter's in my head and in my heart: + I will be bitter with him and passing short. + Go with me, Silvius. + + [Exeunt] + + + + + AS YOU LIKE IT + + +ACT IV + + + +SCENE I The forest. + + + [Enter ROSALIND, CELIA, and JAQUES] + +JAQUES I prithee, pretty youth, let me be better acquainted + with thee. + +ROSALIND They say you are a melancholy fellow. + +JAQUES I am so; I do love it better than laughing. + +ROSALIND Those that are in extremity of either are abominable + fellows and betray themselves to every modern + censure worse than drunkards. + +JAQUES Why, 'tis good to be sad and say nothing. + +ROSALIND Why then, 'tis good to be a post. + +JAQUES I have neither the scholar's melancholy, which is + emulation, nor the musician's, which is fantastical, + nor the courtier's, which is proud, nor the + soldier's, which is ambitious, nor the lawyer's, + which is politic, nor the lady's, which is nice, nor + the lover's, which is all these: but it is a + melancholy of mine own, compounded of many simples, + extracted from many objects, and indeed the sundry's + contemplation of my travels, in which my often + rumination wraps me m a most humorous sadness. + +ROSALIND A traveller! By my faith, you have great reason to + be sad: I fear you have sold your own lands to see + other men's; then, to have seen much and to have + nothing, is to have rich eyes and poor hands. + +JAQUES Yes, I have gained my experience. + +ROSALIND And your experience makes you sad: I had rather have + a fool to make me merry than experience to make me + sad; and to travel for it too! + + [Enter ORLANDO] + +ORLANDO Good day and happiness, dear Rosalind! + +JAQUES Nay, then, God be wi' you, an you talk in blank verse. + + [Exit] + +ROSALIND Farewell, Monsieur Traveller: look you lisp and + wear strange suits, disable all the benefits of your + own country, be out of love with your nativity and + almost chide God for making you that countenance you + are, or I will scarce think you have swam in a + gondola. Why, how now, Orlando! where have you been + all this while? You a lover! An you serve me such + another trick, never come in my sight more. + +ORLANDO My fair Rosalind, I come within an hour of my promise. + +ROSALIND Break an hour's promise in love! He that will + divide a minute into a thousand parts and break but + a part of the thousandth part of a minute in the + affairs of love, it may be said of him that Cupid + hath clapped him o' the shoulder, but I'll warrant + him heart-whole. + +ORLANDO Pardon me, dear Rosalind. + +ROSALIND Nay, an you be so tardy, come no more in my sight: I + had as lief be wooed of a snail. + +ORLANDO Of a snail? + +ROSALIND Ay, of a snail; for though he comes slowly, he + carries his house on his head; a better jointure, + I think, than you make a woman: besides he brings + his destiny with him. + +ORLANDO What's that? + +ROSALIND Why, horns, which such as you are fain to be + beholding to your wives for: but he comes armed in + his fortune and prevents the slander of his wife. + +ORLANDO Virtue is no horn-maker; and my Rosalind is virtuous. + +ROSALIND And I am your Rosalind. + +CELIA It pleases him to call you so; but he hath a + Rosalind of a better leer than you. + +ROSALIND Come, woo me, woo me, for now I am in a holiday + humour and like enough to consent. What would you + say to me now, an I were your very very Rosalind? + +ORLANDO I would kiss before I spoke. + +ROSALIND Nay, you were better speak first, and when you were + gravelled for lack of matter, you might take + occasion to kiss. Very good orators, when they are + out, they will spit; and for lovers lacking--God + warn us!--matter, the cleanliest shift is to kiss. + +ORLANDO How if the kiss be denied? + +ROSALIND Then she puts you to entreaty, and there begins new matter. + +ORLANDO Who could be out, being before his beloved mistress? + +ROSALIND Marry, that should you, if I were your mistress, or + I should think my honesty ranker than my wit. + +ORLANDO What, of my suit? + +ROSALIND Not out of your apparel, and yet out of your suit. + Am not I your Rosalind? + +ORLANDO I take some joy to say you are, because I would be + talking of her. + +ROSALIND Well in her person I say I will not have you. + +ORLANDO Then in mine own person I die. + +ROSALIND No, faith, die by attorney. The poor world is + almost six thousand years old, and in all this time + there was not any man died in his own person, + videlicit, in a love-cause. Troilus had his brains + dashed out with a Grecian club; yet he did what he + could to die before, and he is one of the patterns + of love. Leander, he would have lived many a fair + year, though Hero had turned nun, if it had not been + for a hot midsummer night; for, good youth, he went + but forth to wash him in the Hellespont and being + taken with the cramp was drowned and the foolish + coroners of that age found it was 'Hero of Sestos.' + But these are all lies: men have died from time to + time and worms have eaten them, but not for love. + +ORLANDO I would not have my right Rosalind of this mind, + for, I protest, her frown might kill me. + +ROSALIND By this hand, it will not kill a fly. But come, now + I will be your Rosalind in a more coming-on + disposition, and ask me what you will. I will grant + it. + +ORLANDO Then love me, Rosalind. + +ROSALIND Yes, faith, will I, Fridays and Saturdays and all. + +ORLANDO And wilt thou have me? + +ROSALIND Ay, and twenty such. + +ORLANDO What sayest thou? + +ROSALIND Are you not good? + +ORLANDO I hope so. + +ROSALIND Why then, can one desire too much of a good thing? + Come, sister, you shall be the priest and marry us. + Give me your hand, Orlando. What do you say, sister? + +ORLANDO Pray thee, marry us. + +CELIA I cannot say the words. + +ROSALIND You must begin, 'Will you, Orlando--' + +CELIA Go to. Will you, Orlando, have to wife this Rosalind? + +ORLANDO I will. + +ROSALIND Ay, but when? + +ORLANDO Why now; as fast as she can marry us. + +ROSALIND Then you must say 'I take thee, Rosalind, for wife.' + +ORLANDO I take thee, Rosalind, for wife. + +ROSALIND I might ask you for your commission; but I do take + thee, Orlando, for my husband: there's a girl goes + before the priest; and certainly a woman's thought + runs before her actions. + +ORLANDO So do all thoughts; they are winged. + +ROSALIND Now tell me how long you would have her after you + have possessed her. + +ORLANDO For ever and a day. + +ROSALIND Say 'a day,' without the 'ever.' No, no, Orlando; + men are April when they woo, December when they wed: + maids are May when they are maids, but the sky + changes when they are wives. I will be more jealous + of thee than a Barbary cock-pigeon over his hen, + more clamorous than a parrot against rain, more + new-fangled than an ape, more giddy in my desires + than a monkey: I will weep for nothing, like Diana + in the fountain, and I will do that when you are + disposed to be merry; I will laugh like a hyen, and + that when thou art inclined to sleep. + +ORLANDO But will my Rosalind do so? + +ROSALIND By my life, she will do as I do. + +ORLANDO O, but she is wise. + +ROSALIND Or else she could not have the wit to do this: the + wiser, the waywarder: make the doors upon a woman's + wit and it will out at the casement; shut that and + 'twill out at the key-hole; stop that, 'twill fly + with the smoke out at the chimney. + +ORLANDO A man that had a wife with such a wit, he might say + 'Wit, whither wilt?' + +ROSALIND Nay, you might keep that cheque for it till you met + your wife's wit going to your neighbour's bed. + +ORLANDO And what wit could wit have to excuse that? + +ROSALIND Marry, to say she came to seek you there. You shall + never take her without her answer, unless you take + her without her tongue. O, that woman that cannot + make her fault her husband's occasion, let her + never nurse her child herself, for she will breed + it like a fool! + +ORLANDO For these two hours, Rosalind, I will leave thee. + +ROSALIND Alas! dear love, I cannot lack thee two hours. + +ORLANDO I must attend the duke at dinner: by two o'clock I + will be with thee again. + +ROSALIND Ay, go your ways, go your ways; I knew what you + would prove: my friends told me as much, and I + thought no less: that flattering tongue of yours + won me: 'tis but one cast away, and so, come, + death! Two o'clock is your hour? + +ORLANDO Ay, sweet Rosalind. + +ROSALIND By my troth, and in good earnest, and so God mend + me, and by all pretty oaths that are not dangerous, + if you break one jot of your promise or come one + minute behind your hour, I will think you the most + pathetical break-promise and the most hollow lover + and the most unworthy of her you call Rosalind that + may be chosen out of the gross band of the + unfaithful: therefore beware my censure and keep + your promise. + +ORLANDO With no less religion than if thou wert indeed my + Rosalind: so adieu. + +ROSALIND Well, Time is the old justice that examines all such + offenders, and let Time try: adieu. + + [Exit ORLANDO] + +CELIA You have simply misused our sex in your love-prate: + we must have your doublet and hose plucked over your + head, and show the world what the bird hath done to + her own nest. + +ROSALIND O coz, coz, coz, my pretty little coz, that thou + didst know how many fathom deep I am in love! But + it cannot be sounded: my affection hath an unknown + bottom, like the bay of Portugal. + +CELIA Or rather, bottomless, that as fast as you pour + affection in, it runs out. + +ROSALIND No, that same wicked bastard of Venus that was begot + of thought, conceived of spleen and born of madness, + that blind rascally boy that abuses every one's eyes + because his own are out, let him be judge how deep I + am in love. I'll tell thee, Aliena, I cannot be out + of the sight of Orlando: I'll go find a shadow and + sigh till he come. + +CELIA And I'll sleep. + + [Exeunt] + + + + + AS YOU LIKE IT + + +ACT IV + + + +SCENE II The forest. + + + [Enter JAQUES, Lords, and Foresters] + +JAQUES Which is he that killed the deer? + +A Lord Sir, it was I. + +JAQUES Let's present him to the duke, like a Roman + conqueror; and it would do well to set the deer's + horns upon his head, for a branch of victory. Have + you no song, forester, for this purpose? + +Forester Yes, sir. + +JAQUES Sing it: 'tis no matter how it be in tune, so it + make noise enough. + + SONG. +Forester What shall he have that kill'd the deer? + His leather skin and horns to wear. + Then sing him home; + + [The rest shall bear this burden] + + Take thou no scorn to wear the horn; + It was a crest ere thou wast born: + Thy father's father wore it, + And thy father bore it: + The horn, the horn, the lusty horn + Is not a thing to laugh to scorn. + + [Exeunt] + + + + + AS YOU LIKE IT + + +ACT IV + + + +SCENE III The forest. + + + [Enter ROSALIND and CELIA] + +ROSALIND How say you now? Is it not past two o'clock? and + here much Orlando! + +CELIA I warrant you, with pure love and troubled brain, he + hath ta'en his bow and arrows and is gone forth to + sleep. Look, who comes here. + + [Enter SILVIUS] + +SILVIUS My errand is to you, fair youth; + My gentle Phebe bid me give you this: + I know not the contents; but, as I guess + By the stern brow and waspish action + Which she did use as she was writing of it, + It bears an angry tenor: pardon me: + I am but as a guiltless messenger. + +ROSALIND Patience herself would startle at this letter + And play the swaggerer; bear this, bear all: + She says I am not fair, that I lack manners; + She calls me proud, and that she could not love me, + Were man as rare as phoenix. 'Od's my will! + Her love is not the hare that I do hunt: + Why writes she so to me? Well, shepherd, well, + This is a letter of your own device. + +SILVIUS No, I protest, I know not the contents: + Phebe did write it. + +ROSALIND Come, come, you are a fool + And turn'd into the extremity of love. + I saw her hand: she has a leathern hand. + A freestone-colour'd hand; I verily did think + That her old gloves were on, but 'twas her hands: + She has a huswife's hand; but that's no matter: + I say she never did invent this letter; + This is a man's invention and his hand. + +SILVIUS Sure, it is hers. + +ROSALIND Why, 'tis a boisterous and a cruel style. + A style for-challengers; why, she defies me, + Like Turk to Christian: women's gentle brain + Could not drop forth such giant-rude invention + Such Ethiope words, blacker in their effect + Than in their countenance. Will you hear the letter? + +SILVIUS So please you, for I never heard it yet; + Yet heard too much of Phebe's cruelty. + +ROSALIND She Phebes me: mark how the tyrant writes. + + [Reads] + + Art thou god to shepherd turn'd, + That a maiden's heart hath burn'd? + Can a woman rail thus? + +SILVIUS Call you this railing? + +ROSALIND [Reads] + + Why, thy godhead laid apart, + Warr'st thou with a woman's heart? + Did you ever hear such railing? + Whiles the eye of man did woo me, + That could do no vengeance to me. + Meaning me a beast. + If the scorn of your bright eyne + Have power to raise such love in mine, + Alack, in me what strange effect + Would they work in mild aspect! + Whiles you chid me, I did love; + How then might your prayers move! + He that brings this love to thee + Little knows this love in me: + And by him seal up thy mind; + Whether that thy youth and kind + Will the faithful offer take + Of me and all that I can make; + Or else by him my love deny, + And then I'll study how to die. + +SILVIUS Call you this chiding? + +CELIA Alas, poor shepherd! + +ROSALIND Do you pity him? no, he deserves no pity. Wilt + thou love such a woman? What, to make thee an + instrument and play false strains upon thee! not to + be endured! Well, go your way to her, for I see + love hath made thee a tame snake, and say this to + her: that if she love me, I charge her to love + thee; if she will not, I will never have her unless + thou entreat for her. If you be a true lover, + hence, and not a word; for here comes more company. + + [Exit SILVIUS] + + [Enter OLIVER] + +OLIVER Good morrow, fair ones: pray you, if you know, + Where in the purlieus of this forest stands + A sheep-cote fenced about with olive trees? + +CELIA West of this place, down in the neighbour bottom: + The rank of osiers by the murmuring stream + Left on your right hand brings you to the place. + But at this hour the house doth keep itself; + There's none within. + +OLIVER If that an eye may profit by a tongue, + Then should I know you by description; + Such garments and such years: 'The boy is fair, + Of female favour, and bestows himself + Like a ripe sister: the woman low + And browner than her brother.' Are not you + The owner of the house I did inquire for? + +CELIA It is no boast, being ask'd, to say we are. + +OLIVER Orlando doth commend him to you both, + And to that youth he calls his Rosalind + He sends this bloody napkin. Are you he? + +ROSALIND I am: what must we understand by this? + +OLIVER Some of my shame; if you will know of me + What man I am, and how, and why, and where + This handkercher was stain'd. + +CELIA I pray you, tell it. + +OLIVER When last the young Orlando parted from you + He left a promise to return again + Within an hour, and pacing through the forest, + Chewing the food of sweet and bitter fancy, + Lo, what befell! he threw his eye aside, + And mark what object did present itself: + Under an oak, whose boughs were moss'd with age + And high top bald with dry antiquity, + A wretched ragged man, o'ergrown with hair, + Lay sleeping on his back: about his neck + A green and gilded snake had wreathed itself, + Who with her head nimble in threats approach'd + The opening of his mouth; but suddenly, + Seeing Orlando, it unlink'd itself, + And with indented glides did slip away + Into a bush: under which bush's shade + A lioness, with udders all drawn dry, + Lay couching, head on ground, with catlike watch, + When that the sleeping man should stir; for 'tis + The royal disposition of that beast + To prey on nothing that doth seem as dead: + This seen, Orlando did approach the man + And found it was his brother, his elder brother. + +CELIA O, I have heard him speak of that same brother; + And he did render him the most unnatural + That lived amongst men. + +OLIVER And well he might so do, + For well I know he was unnatural. + +ROSALIND But, to Orlando: did he leave him there, + Food to the suck'd and hungry lioness? + +OLIVER Twice did he turn his back and purposed so; + But kindness, nobler ever than revenge, + And nature, stronger than his just occasion, + Made him give battle to the lioness, + Who quickly fell before him: in which hurtling + From miserable slumber I awaked. + +CELIA Are you his brother? + +ROSALIND Wast you he rescued? + +CELIA Was't you that did so oft contrive to kill him? + +OLIVER 'Twas I; but 'tis not I I do not shame + To tell you what I was, since my conversion + So sweetly tastes, being the thing I am. + +ROSALIND But, for the bloody napkin? + +OLIVER By and by. + When from the first to last betwixt us two + Tears our recountments had most kindly bathed, + As how I came into that desert place:-- + In brief, he led me to the gentle duke, + Who gave me fresh array and entertainment, + Committing me unto my brother's love; + Who led me instantly unto his cave, + There stripp'd himself, and here upon his arm + The lioness had torn some flesh away, + Which all this while had bled; and now he fainted + And cried, in fainting, upon Rosalind. + Brief, I recover'd him, bound up his wound; + And, after some small space, being strong at heart, + He sent me hither, stranger as I am, + To tell this story, that you might excuse + His broken promise, and to give this napkin + Dyed in his blood unto the shepherd youth + That he in sport doth call his Rosalind. + + [ROSALIND swoons] + +CELIA Why, how now, Ganymede! sweet Ganymede! + +OLIVER Many will swoon when they do look on blood. + +CELIA There is more in it. Cousin Ganymede! + +OLIVER Look, he recovers. + +ROSALIND I would I were at home. + +CELIA We'll lead you thither. + I pray you, will you take him by the arm? + +OLIVER Be of good cheer, youth: you a man! you lack a + man's heart. + +ROSALIND I do so, I confess it. Ah, sirrah, a body would + think this was well counterfeited! I pray you, tell + your brother how well I counterfeited. Heigh-ho! + +OLIVER This was not counterfeit: there is too great + testimony in your complexion that it was a passion + of earnest. + +ROSALIND Counterfeit, I assure you. + +OLIVER Well then, take a good heart and counterfeit to be a man. + +ROSALIND So I do: but, i' faith, I should have been a woman by right. + +CELIA Come, you look paler and paler: pray you, draw + homewards. Good sir, go with us. + +OLIVER That will I, for I must bear answer back + How you excuse my brother, Rosalind. + +ROSALIND I shall devise something: but, I pray you, commend + my counterfeiting to him.

I do now remember a saying, + 'The fool doth think he is wise, but the wise man + knows himself to be a fool.'

You do love this maid? + +WILLIAM I do, sir. + +TOUCHSTONE Give me your hand. Art thou learned? + +WILLIAM No, sir. + +TOUCHSTONE Then learn this of me: to have, is to have; for it + is a figure in rhetoric that drink, being poured out + of a cup into a glass, by filling the one doth empty + the other; for all your writers do consent that ipse + is he: now, you are not ipse, for I am he. + +WILLIAM Which he, sir? + +TOUCHSTONE He, sir, that must marry this woman. Therefore, you + clown, abandon,--which is in the vulgar leave,--the + society,--which in the boorish is company,--of this + female,--which in the common is woman; which + together is, abandon the society of this female, or, + clown, thou perishest; or, to thy better + understanding, diest; or, to wit I kill thee, make + thee away, translate thy life into death, thy + liberty into bondage: I will deal in poison with + thee, or in bastinado, or in steel; I will bandy + with thee in faction; I will o'errun thee with + policy; I will kill thee a hundred and fifty ways: + therefore tremble and depart. + +AUDREY Do, good William. + +WILLIAM God rest you merry, sir. + + [Exit] + + [Enter CORIN] + +CORIN Our master and mistress seeks you; come, away, away! + +TOUCHSTONE Trip, Audrey! trip, Audrey! I attend, I attend. + + [Exeunt] + + + + + AS YOU LIKE IT + + +ACT V + + + +SCENE II The forest. + + + [Enter ORLANDO and OLIVER] + +ORLANDO Is't possible that on so little acquaintance you + should like her? that but seeing you should love + her? and loving woo? and, wooing, she should + grant? and will you persever to enjoy her? + +OLIVER Neither call the giddiness of it in question, the + poverty of her, the small acquaintance, my sudden + wooing, nor her sudden consenting; but say with me, + I love Aliena; say with her that she loves me; + consent with both that we may enjoy each other: it + shall be to your good; for my father's house and all + the revenue that was old Sir Rowland's will I + estate upon you, and here live and die a shepherd. + +ORLANDO You have my consent. Let your wedding be to-morrow: + thither will I invite the duke and all's contented + followers. Go you and prepare Aliena; for look + you, here comes my Rosalind. + + [Enter ROSALIND] + +ROSALIND God save you, brother. + +OLIVER And you, fair sister. + + [Exit] + +ROSALIND O, my dear Orlando, how it grieves me to see thee + wear thy heart in a scarf! + +ORLANDO It is my arm. + +ROSALIND I thought thy heart had been wounded with the claws + of a lion. + +ORLANDO Wounded it is, but with the eyes of a lady. + +ROSALIND Did your brother tell you how I counterfeited to + swoon when he showed me your handkerchief? + +ORLANDO Ay, and greater wonders than that. + +ROSALIND O, I know where you are: nay, 'tis true: there was + never any thing so sudden but the fight of two rams + and Caesar's thrasonical brag of 'I came, saw, and + overcame:' for your brother and my sister no sooner + met but they looked, no sooner looked but they + loved, no sooner loved but they sighed, no sooner + sighed but they asked one another the reason, no + sooner knew the reason but they sought the remedy; + and in these degrees have they made a pair of stairs + to marriage which they will climb incontinent, or + else be incontinent before marriage: they are in + the very wrath of love and they will together; clubs + cannot part them. + +ORLANDO They shall be married to-morrow, and I will bid the + duke to the nuptial. But, O, how bitter a thing it + is to look into happiness through another man's + eyes! By so much the more shall I to-morrow be at + the height of heart-heaviness, by how much I shall + think my brother happy in having what he wishes for. + +ROSALIND Why then, to-morrow I cannot serve your turn for Rosalind? + +ORLANDO I can live no longer by thinking. + +ROSALIND I will weary you then no longer with idle talking. + Know of me then, for now I speak to some purpose, + that I know you are a gentleman of good conceit: I + speak not this that you should bear a good opinion + of my knowledge, insomuch I say I know you are; + neither do I labour for a greater esteem than may in + some little measure draw a belief from you, to do + yourself good and not to grace me. Believe then, if + you please, that I can do strange things: I have, + since I was three year old, conversed with a + magician, most profound in his art and yet not + damnable. If you do love Rosalind so near the heart + as your gesture cries it out, when your brother + marries Aliena, shall you marry her: I know into + what straits of fortune she is driven; and it is + not impossible to me, if it appear not inconvenient + to you, to set her before your eyes tomorrow human + as she is and without any danger. + +ORLANDO Speakest thou in sober meanings? + +ROSALIND By my life, I do; which I tender dearly, though I + say I am a magician. Therefore, put you in your + best array: bid your friends; for if you will be + married to-morrow, you shall, and to Rosalind, if you will. + + [Enter SILVIUS and PHEBE] + + Look, here comes a lover of mine and a lover of hers. + +PHEBE Youth, you have done me much ungentleness, + To show the letter that I writ to you. + +ROSALIND I care not if I have: it is my study + To seem despiteful and ungentle to you: + You are there followed by a faithful shepherd; + Look upon him, love him; he worships you. + +PHEBE Good shepherd, tell this youth what 'tis to love. + +SILVIUS It is to be all made of sighs and tears; + And so am I for Phebe. + +PHEBE And I for Ganymede. + +ORLANDO And I for Rosalind. + +ROSALIND And I for no woman. + +SILVIUS It is to be all made of faith and service; + And so am I for Phebe. + +PHEBE And I for Ganymede. + +ORLANDO And I for Rosalind. + +ROSALIND And I for no woman. + +SILVIUS It is to be all made of fantasy, + All made of passion and all made of wishes, + All adoration, duty, and observance, + All humbleness, all patience and impatience, + All purity, all trial, all observance; + And so am I for Phebe. + +PHEBE And so am I for Ganymede. + +ORLANDO And so am I for Rosalind. + +ROSALIND And so am I for no woman. + +PHEBE If this be so, why blame you me to love you? + +SILVIUS If this be so, why blame you me to love you? + +ORLANDO If this be so, why blame you me to love you? + +ROSALIND Who do you speak to, 'Why blame you me to love you?' + +ORLANDO To her that is not here, nor doth not hear. + +ROSALIND Pray you, no more of this; 'tis like the howling + of Irish wolves against the moon. + + [To SILVIUS] + + I will help you, if I can: + + [To PHEBE] + + I would love you, if I could. To-morrow meet me all together. + + [To PHEBE] + + I will marry you, if ever I marry woman, and I'll be + married to-morrow: + + [To ORLANDO] + + I will satisfy you, if ever I satisfied man, and you + shall be married to-morrow: + + [To SILVIUS] + + I will content you, if what pleases you contents + you, and you shall be married to-morrow. + + [To ORLANDO] + + As you love Rosalind, meet: + + [To SILVIUS] + + as you love Phebe, meet: and as I love no woman, + I'll meet. So fare you well: I have left you commands. + +SILVIUS I'll not fail, if I live. + +PHEBE Nor I. + +ORLANDO Nor I. + + [Exeunt] + + + + + AS YOU LIKE IT + + +ACT V + + + +SCENE III The forest. + + + [Enter TOUCHSTONE and AUDREY] + +TOUCHSTONE To-morrow is the joyful day, Audrey; to-morrow will + we be married. + +AUDREY I do desire it with all my heart; and I hope it is + no dishonest desire to desire to be a woman of the + world. Here comes two of the banished duke's pages. + + [Enter two Pages] + +First Page Well met, honest gentleman. + +TOUCHSTONE By my troth, well met. Come, sit, sit, and a song. + +Second Page We are for you: sit i' the middle. + +First Page Shall we clap into't roundly, without hawking or + spitting or saying we are hoarse, which are the only + prologues to a bad voice? + +Second Page I'faith, i'faith; and both in a tune, like two + gipsies on a horse. + + SONG. + It was a lover and his lass, + With a hey, and a ho, and a hey nonino, + That o'er the green corn-field did pass + In the spring time, the only pretty ring time, + When birds do sing, hey ding a ding, ding: + Sweet lovers love the spring. + + Between the acres of the rye, + With a hey, and a ho, and a hey nonino + These pretty country folks would lie, + In spring time, &c. + + This carol they began that hour, + With a hey, and a ho, and a hey nonino, + How that a life was but a flower + In spring time, &c. + + And therefore take the present time, + With a hey, and a ho, and a hey nonino; + For love is crowned with the prime + In spring time, &c. + +TOUCHSTONE Truly, young gentlemen, though there was no great + matter in the ditty, yet the note was very + untuneable. + +First Page You are deceived, sir: we kept time, we lost not our time. + +TOUCHSTONE By my troth, yes; I count it but time lost to hear + such a foolish song. God be wi' you; and God mend + your voices! Come, Audrey. + + [Exeunt] + + + + + AS YOU LIKE IT + + +ACT V + + + +SCENE IV The forest. + + + [Enter DUKE SENIOR, AMIENS, JAQUES, ORLANDO, OLIVER, + and CELIA] + +DUKE SENIOR Dost thou believe, Orlando, that the boy + Can do all this that he hath promised? + +ORLANDO I sometimes do believe, and sometimes do not; + As those that fear they hope, and know they fear. + + [Enter ROSALIND, SILVIUS, and PHEBE] + +ROSALIND Patience once more, whiles our compact is urged: + You say, if I bring in your Rosalind, + You will bestow her on Orlando here? + +DUKE SENIOR That would I, had I kingdoms to give with her. + +ROSALIND And you say, you will have her, when I bring her? + +ORLANDO That would I, were I of all kingdoms king. + +ROSALIND You say, you'll marry me, if I be willing? + +PHEBE That will I, should I die the hour after. + +ROSALIND But if you do refuse to marry me, + You'll give yourself to this most faithful shepherd? + +PHEBE So is the bargain. + +ROSALIND You say, that you'll have Phebe, if she will? + +SILVIUS Though to have her and death were both one thing. + +ROSALIND I have promised to make all this matter even. + Keep you your word, O duke, to give your daughter; + You yours, Orlando, to receive his daughter: + Keep your word, Phebe, that you'll marry me, + Or else refusing me, to wed this shepherd: + Keep your word, Silvius, that you'll marry her. + If she refuse me: and from hence I go, + To make these doubts all even. + + [Exeunt ROSALIND and CELIA] + +DUKE SENIOR I do remember in this shepherd boy + Some lively touches of my daughter's favour. + +ORLANDO My lord, the first time that I ever saw him + Methought he was a brother to your daughter: + But, my good lord, this boy is forest-born, + And hath been tutor'd in the rudiments + Of many desperate studies by his uncle, + Whom he reports to be a great magician, + Obscured in the circle of this forest. + + [Enter TOUCHSTONE and AUDREY] + +JAQUES There is, sure, another flood toward, and these + couples are coming to the ark. Here comes a pair of + very strange beasts, which in all tongues are called fools. + +TOUCHSTONE Salutation and greeting to you all! + +JAQUES Good my lord, bid him welcome: this is the + motley-minded gentleman that I have so often met in + the forest: he hath been a courtier, he swears. + +TOUCHSTONE If any man doubt that, let him put me to my + purgation. I have trod a measure; I have flattered + a lady; I have been politic with my friend, smooth + with mine enemy; I have undone three tailors; I have + had four quarrels, and like to have fought one. + +JAQUES And how was that ta'en up? + +TOUCHSTONE Faith, we met, and found the quarrel was upon the + seventh cause. + +JAQUES How seventh cause? Good my lord, like this fellow. + +DUKE SENIOR I like him very well. + +TOUCHSTONE God 'ild you, sir; I desire you of the like. I + press in here, sir, amongst the rest of the country + copulatives, to swear and to forswear: according as + marriage binds and blood breaks: a poor virgin, + sir, an ill-favoured thing, sir, but mine own; a poor + humour of mine, sir, to take that that no man else + will: rich honesty dwells like a miser, sir, in a + poor house; as your pearl in your foul oyster. + +DUKE SENIOR By my faith, he is very swift and sententious. + +TOUCHSTONE According to the fool's bolt, sir, and such dulcet diseases. + +JAQUES But, for the seventh cause; how did you find the + quarrel on the seventh cause? + +TOUCHSTONE Upon a lie seven times removed:--bear your body more + seeming, Audrey:--as thus, sir. I did dislike the + cut of a certain courtier's beard: he sent me word, + if I said his beard was not cut well, he was in the + mind it was: this is called the Retort Courteous. + If I sent him word again 'it was not well cut,' he + would send me word, he cut it to please himself: + this is called the Quip Modest. If again 'it was + not well cut,' he disabled my judgment: this is + called the Reply Churlish. If again 'it was not + well cut,' he would answer, I spake not true: this + is called the Reproof Valiant. If again 'it was not + well cut,' he would say I lied: this is called the + Counter-cheque Quarrelsome: and so to the Lie + Circumstantial and the Lie Direct. + +JAQUES And how oft did you say his beard was not well cut? + +TOUCHSTONE I durst go no further than the Lie Circumstantial, + nor he durst not give me the Lie Direct; and so we + measured swords and parted. + +JAQUES Can you nominate in order now the degrees of the lie? + +TOUCHSTONE O sir, we quarrel in print, by the book; as you have + books for good manners: I will name you the degrees. + The first, the Retort Courteous; the second, the + Quip Modest; the third, the Reply Churlish; the + fourth, the Reproof Valiant; the fifth, the + Countercheque Quarrelsome; the sixth, the Lie with + Circumstance; the seventh, the Lie Direct. All + these you may avoid but the Lie Direct; and you may + avoid that too, with an If. I knew when seven + justices could not take up a quarrel, but when the + parties were met themselves, one of them thought but + of an If, as, 'If you said so, then I said so;' and + they shook hands and swore brothers. Your If is the + only peacemaker; much virtue in If. + +JAQUES Is not this a rare fellow, my lord? he's as good at + any thing and yet a fool. + +DUKE SENIOR He uses his folly like a stalking-horse and under + the presentation of that he shoots his wit. + + [Enter HYMEN, ROSALIND, and CELIA] + + [Still Music] + +HYMEN Then is there mirth in heaven, + When earthly things made even + Atone together. + Good duke, receive thy daughter + Hymen from heaven brought her, + Yea, brought her hither, + That thou mightst join her hand with his + Whose heart within his bosom is. + +ROSALIND [To DUKE SENIOR] To you I give myself, for I am yours. + + [To ORLANDO] + + To you I give myself, for I am yours. + +DUKE SENIOR If there be truth in sight, you are my daughter. + +ORLANDO If there be truth in sight, you are my Rosalind. + +PHEBE If sight and shape be true, + Why then, my love adieu! + +ROSALIND I'll have no father, if you be not he: + I'll have no husband, if you be not he: + Nor ne'er wed woman, if you be not she. + +HYMEN Peace, ho! I bar confusion: + 'Tis I must make conclusion + Of these most strange events: + Here's eight that must take hands + To join in Hymen's bands, + If truth holds true contents. + You and you no cross shall part: + You and you are heart in heart + You to his love must accord, + Or have a woman to your lord: + You and you are sure together, + As the winter to foul weather. + Whiles a wedlock-hymn we sing, + Feed yourselves with questioning; + That reason wonder may diminish, + How thus we met, and these things finish. + + SONG. + Wedding is great Juno's crown: + O blessed bond of board and bed! + 'Tis Hymen peoples every town; + High wedlock then be honoured: + Honour, high honour and renown, + To Hymen, god of every town! + +DUKE SENIOR O my dear niece, welcome thou art to me! + Even daughter, welcome, in no less degree. + +PHEBE I will not eat my word, now thou art mine; + Thy faith my fancy to thee doth combine. + + [Enter JAQUES DE BOYS] + +JAQUES DE BOYS Let me have audience for a word or two: + I am the second son of old Sir Rowland, + That bring these tidings to this fair assembly. + Duke Frederick, hearing how that every day + Men of great worth resorted to this forest, + Address'd a mighty power; which were on foot, + In his own conduct, purposely to take + His brother here and put him to the sword: + And to the skirts of this wild wood he came; + Where meeting with an old religious man, + After some question with him, was converted + Both from his enterprise and from the world, + His crown bequeathing to his banish'd brother, + And all their lands restored to them again + That were with him exiled. This to be true, + I do engage my life. + +DUKE SENIOR Welcome, young man; + Thou offer'st fairly to thy brothers' wedding: + To one his lands withheld, and to the other + A land itself at large, a potent dukedom. + First, in this forest, let us do those ends + That here were well begun and well begot: + And after, every of this happy number + That have endured shrewd days and nights with us + Shall share the good of our returned fortune, + According to the measure of their states. + Meantime, forget this new-fall'n dignity + And fall into our rustic revelry. + Play, music! And you, brides and bridegrooms all, + With measure heap'd in joy, to the measures fall. + +JAQUES Sir, by your patience. If I heard you rightly, + The duke hath put on a religious life + And thrown into neglect the pompous court? + +JAQUES DE BOYS He hath. + +JAQUES To him will I : out of these convertites + There is much matter to be heard and learn'd. + + [To DUKE SENIOR] + + You to your former honour I bequeath; + Your patience and your virtue well deserves it: + + [To ORLANDO] + + You to a love that your true faith doth merit: + + [To OLIVER] + + You to your land and love and great allies: + + [To SILVIUS] + + You to a long and well-deserved bed: + + [To TOUCHSTONE] + + And you to wrangling; for thy loving voyage + Is but for two months victuall'd. So, to your pleasures: + I am for other than for dancing measures. + +DUKE SENIOR Stay, Jaques, stay. + +JAQUES To see no pastime I what you would have + I'll stay to know at your abandon'd cave. + + [Exit] + +DUKE SENIOR Proceed, proceed: we will begin these rites, + As we do trust they'll end, in true delights. + + [A dance] + + + + + AS YOU LIKE IT + + EPILOGUE + + +ROSALIND It is not the fashion to see the lady the epilogue; + but it is no more unhandsome than to see the lord + the prologue. If it be true that good wine needs + no bush, 'tis true that a good play needs no + epilogue; yet to good wine they do use good bushes, + and good plays prove the better by the help of good + epilogues. What a case am I in then, that am + neither a good epilogue nor cannot insinuate with + you in the behalf of a good play! I am not + furnished like a beggar, therefore to beg will not + become me: my way is to conjure you; and I'll begin + with the women. I charge you, O women, for the love + you bear to men, to like as much of this play as + please you: and I charge you, O men, for the love + you bear to women--as I perceive by your simpering, + none of you hates them--that between you and the + women the play may please. If I were a woman I + would kiss as many of you as had beards that pleased + me, complexions that liked me and breaths that I + defied not: and, I am sure, as many as have good + beards or good faces or sweet breaths will, for my + kind offer, when I make curtsy, bid me farewell. + + [Exeunt] diff --git a/chromium/third_party/snappy/src/testdata/baddata1.snappy b/chromium/third_party/snappy/src/testdata/baddata1.snappy new file mode 100644 index 00000000000..99d970fb4b2 Binary files /dev/null and b/chromium/third_party/snappy/src/testdata/baddata1.snappy differ diff --git a/chromium/third_party/snappy/src/testdata/baddata2.snappy b/chromium/third_party/snappy/src/testdata/baddata2.snappy new file mode 100644 index 00000000000..8f5cb13ee23 Binary files /dev/null and b/chromium/third_party/snappy/src/testdata/baddata2.snappy differ diff --git a/chromium/third_party/snappy/src/testdata/baddata3.snappy b/chromium/third_party/snappy/src/testdata/baddata3.snappy new file mode 100644 index 00000000000..774aead4dcd Binary files /dev/null and b/chromium/third_party/snappy/src/testdata/baddata3.snappy differ diff --git a/chromium/third_party/snappy/src/testdata/cp.html b/chromium/third_party/snappy/src/testdata/cp.html new file mode 100644 index 00000000000..1d0ca37eb97 --- /dev/null +++ b/chromium/third_party/snappy/src/testdata/cp.html @@ -0,0 +1,645 @@ + +Compression Pointers + + + + + +
