"That's it," said Piper. "Of course we may never need anything of the sort—yet it's well to be prepared."
"Suppose we come to an understanding about the signals," suggested Heydon.
"We shall be glad to," assented Bob.
"Well, in case you need assistance of any kind, send up three clouds of smoke, and fire off a gun. You'll find us hiking over here in a hurry."
"And, of course, if the signal comes from our side, we shall expect you to cross the lake in jig time," added Fulmer Robson.
"You can depend upon us," said Bob.
"Well, that point is settled. This locality seems to be a favorite place for hunters, and we're glad of it. A couple of young fellows have a camp near by."
"Yes—their names are Sladder and Musgrove," explained Bob.
"H'm, as I said, it's good to have company, providing we don't take each other for deer or other animals," laughed Piper. "A good, solid pair of shelters you have there, boys."
"Oh, this isn't our first camping trip," said Hackett. "We know a thing or two about it."
