"Hey, fellows, I've got an idea," said Bob, suddenly. "A dandy one, too."

"Quick—speak out. Don't let it get away," grinned Dick. "Something tells me it's something."

"Well, why not make a raft?"

"A raft!" echoed his companions.

"Yes! Why not? That's better than swimming, isn't it? We ought to be able to steer with a couple of poles, all right, and keep out of the way of rocks, eh, Havens? Dandy fun, besides."

Jim reflected. "A good scheme, Bob. Only there are some pretty swift rapids. We might get upset in the middle of one—that sounds nice, eh?"

"But if we walk," drawled Dave, "it means a lot more climbing, doesn't it?"

"Sure thing," said Jim.

"Then I say, real loud, build a raft—but do you think it can be done?" An anxious look came over the stout boy's face.

"Of course," asserted Bob, confidently.
