The Caddis Worms soon found that white was not a good color to wear, and they talked of it among themselves. They were very bright larvæ. One day the biggest one was standing on a stem of pickerel-weed, when his sister came toward him. She did not come very fast, because she was neither swimming nor walking, but biting herself along. All the Caddis Worms did this at times, for their legs were weak. She reached as far forward as she could, and fastened her strong jaws in the weed, then she gave a jerk and pulled her body ahead. "It is a very good way to travel," said she, "and such a saving of one's legs." Now she was in so great a hurry that sometimes when she pulled herself ahead, she turned a half-somersault and came down on her back.
