"Better fasten your cocoon to a tree," said a pale bluish-green Promethea Caterpillar. "Put it inside a curled leaf, like mine, and wind silk around the stem to strengthen it. Then you can swing every time the wind blows, and the silk will keep the leaf from wearing out."

"But I don't want to swing," answered the Polyphemus Caterpillar. "I'd rather lie still and think about things."

"Fasten to the twig of a tree," advised a pale green Cecropia Caterpillar with red, yellow, and blue bunches. "Then the wind just moves you a little. Fasten it to a twig and taper it off nicely at each end, and then——"

"Yes," said the Polyphemus Caterpillar, "and then the Blue-Jays and Chickadees will poke wheat or corn or beechnuts into the upper end of it. I don't care to turn my sleeping room into a corn-crib."

Just here some other Polyphemus Caterpillars came along and agreed with their relative. "Go ahead with your tree homes," said they. "We know what we want, and we'll see next summer who knew best."

The Polyphemus cocoons were spun on the ground where the dead leaves had blown in between some stones, and no wandering Cows or Sheep would be likely to step on them. First a mass of coarse silk which it took half a day to make, then an inside coating of a kind of varnish, then as much silk as a Caterpillar could spin in four or five days, next another inside varnishing, and the cocoons were done. As the Polyphemus Caterpillars snuggled down for the long winter's sleep, each said to himself something like this: "Those poor Caterpillars in the trees! How cold they will be! I hope they may come out all right in the spring, but I doubt it very much."

And when the Cecropia and Promethea Caterpillars dozed off for the winter, they said: "What a pity that those Polyphemus Caterpillars would lie around on the ground. Well, we advised them what to do, so it isn't our fault."

They all had a lovely winter, and swung or swayed or lay still, just as they had chosen to do. Early in the spring, the farmer's wife and little girl came out to find wild flowers, and scraped the leaves away from among the stones. Out rolled the cocoon that the first Polyphemus Caterpillar had spun and the farmer's wife picked it up and carried it off. She might have found more cocoons if the little girl had not called her away.

This was how it happened that one May morning a little girl stood by the sitting-room window in the white farmhouse and watched Miss Polyphemus crawl slowly out of her cocoon. A few days before a sour, milky-looking stuff had begun to trickle into the lower end of the cocoon, softening the hard varnish and the soft silken threads until a tiny doorway was opened. Now all was ready and Miss Polyphemus pushed out. She was very wet and weak and forlorn. "Oh," said she to herself, "it is more fun to be a new Caterpillar than it is to be a new Moth. I've only six legs left, and it will be very hard worrying along on these. I shall have to give up walking."

It was discouraging. You can see how it would be. She had been used to having so many legs, and had looked forward all the summer before to the time when she should float lightly through the air and sip honey from flowers. She had dreamed of it all winter. And now here she was—wet and weak, with only six legs left, and four very small and crumpled wings. Her body was so big and fat that she could not hold it up from the window-sill. She wanted to cry—it was all so sad and disappointing. She would have done so, had she not remembered how very unbecoming it is to cry. When she remembered that, she decided to take a nap instead, and that was a most sensible thing to do, for crying always makes matters worse, while sleeping makes them better.
