He said the first he could remember he was a little baby-snail not as big as a pinhead, moving about with hundreds of his brothers in the sand. Yet even then he carried a house on his back, a tiny, perfect shell, into which he could creep when danger threatened.

“Some people say I am very slow,” said the snail, “but they forget I have only one foot and carry my house on my back. Yet I am not complaining, for I have a head in which are my eyes, mouth, feelers, and organs of smell, while my relative, the oyster, having no head, has to wear his eyes, ears, and feelers on his mantle and his mouth near his hinge, poor fellow! Even my own cousin, the land-snail, has her eyes on long feelers, and has to draw them in if danger is near. Then see what a handsome cone-shaped shell I wear; inside there is a kind of spiral staircase, up which I can creep, and I can close my door with a thin film. If I break my shell I patch it with a sticky fluid that hardens and makes my home as good as new. I am an air-breathing creature and go up to the top to set free the bubble of impure air I have breathed and then bring down a bubble of fresh, sweet air. I have a long, ribbon-like tongue covered with teeth, with which I can chew the delicious water-weeds. Really, I consider myself a very lucky creature.”

“It must be a trifle monotonous,” thought the Hyla, as he swam toward the top. “I should want a more stirring life. I wonder what that is!”

What he saw was a small object floating on the top of the water like an odd little boat, only it seemed made of tiny jars with their openings toward the bottom, and out of these jars were darting wee brown wigglers.

“Hello, little chaps! who are you?” called the tree-toad.

“We don’t know, we just got out,” cried the wigglers, “but there is our big brother; ask him.”

The brother was a curious fellow. His body was very slender and of a mottled green colour, and he had large dark eyes. He also wore a huge moustache, which he was always moving about in a curious way, for he used it as a hand for feeding himself. On one side of his tail was a queer little screw he used as a propeller and rudder. He was sailing about at a furious rate, but almost always on his head, with his tail stuck out of the water.

“Allow me to ask what you are doing in that strange position?” inquired the Hyla in his mildest tones.

“Breathing, sir, as I should think you could see,” replied the larva, crossly. “What other way should one breathe?”
