          "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 ever 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 "
          "Duchess, 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.";
