"Well, it looks a little like a worm. It has a long, slender body, but it has six jointed legs, which real worms don't have. See this fellow!" Ben Gile pulled the worm out of its case.
"Oh, see! part of the body is so pale and soft!"
"That, child, is because it is always covered by the little house. The front end and the legs, however, are darker. That's sunburn, I suppose."
"When young Master Caddis-Worm goes out for a swim or a walk it pushes its six legs out-of-doors, and walks along, carrying its house with it. Very convenient, you see! No doors to lock! And if it gets tired it does not have to walk home; it just walks in and goes to sleep under a nice, smooth stone. Some roam about and some stay at home. These creatures are pretty much like human beings in their ways.
"One of the young caddis-worms prefers fishing to walking, like some other young fellows I know. On a stone near its house it spins a fine web, turned up-stream, so that any tender little insects floating down-stream get lodged in it. An easy way to get your dinner—just to go to a net and eat."
The guide paused for a long time, clouds of smoke circling about his white beard and white hair. The children thought he would never go on. "I've had something on my mind for days," he said, "and I'll speak of it now. The boy or girl who learns most about the ants before September 15th shall win a prize. This prize is to be a magnifying-glass, a book of colored plates of the insects, very beautiful and very big, and a five-dollar gold piece."
"A prize, a prize!" shouted the children, jumping madly about, while Mrs. Reece and the guide smiled at each other.
"Now we've had our dinner, our rest, our pipe of peace, a plan for a prize, and we must push on for the camping-ground. Get the canoes ready."
And, with laughter and talking, the canoes were off up the river again.
