One day late in autumn I picked up a tree-toad that was stiff and nearly dead with cold. I put him in a wide-mouthed bottle to thaw, and found by evening that he was quite alive, sitting with his toes turned in, looking much surprised at his new quarters. He made himself at home, however, and settled down comfortably, ready for what might happen next.
The following day he climbed up the side of the bottle and slept several hours, his tiny disked toes holding him as easily and restfully as if he were stretched upon a feather-bed. I turned him upside down; but he knew nothing of it until later when he awoke; then he deliberately turned round with his head up and went to sleep again. At night he was wide awake, winking and blinking at the lamp, and watching me through his window of green glass.
A few nights after his rescue Hyla sat upon the bottom of his bottle in a very queer attitude. His eyes were drawn in, his head was bent down, his feet rolled up--his whole body huddled into a ball less than half its normal size. After a time he began to kick and gasp as if in pain, rolling and unrolling himself desperately. I thought he was dying. He would double up into a bunch, then kick out suddenly and stand up on his hind legs with his mouth wide open as if trying to swallow something. He _was_ trying to swallow something, and the thing had stuck on the way. It was a kind of cord, and ran out of each corner of his mouth, passing over his front legs, thinning and disappearing most strangely along his sides.
With the next gulp I saw the cord slip down a little, and, as it did so, the skin along his sides rolled up. It was his old suit! He was taking it off for a new one; and, instead of giving it to the poor, he was trying to economize by eating it. What a meal! What a way to undress! What curious economy!
Long ago the naturalists told us that the toads ate their skins--after shedding them; but it was never made plain to me that they ate them _while_ changing them--indeed, _swallowed_ them off! Three great gulps more and the suit--shirt, shoes, stockings, and all--disappeared. Then Hyla winked, drew his clean sleeve across his mouth, and settled back with the very air of one who has magnificently sent away the waiter with the change.
