`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!'
