"In case, what?" pursued Davy, who wanted to know everything.

"I thought I heard a voice somewhere, but it might have been a bird in the bushes," Thad continued, in a relieved tone. "Why, I was only going to say in case we had any trouble with these men. But they may not be here at all now. I've got an idea they own another boat, in which they could have slipped away last night while it was so dark."

"Then what's the use of our hunting all over the place as we're doing?" asked Davy, fanning himself with his hat; for the day was turning out warm, and it began to seem like tiresome work, and all for nothing, too.

"In the first place," went on Thad, with that steady glow in his gray eyes that bespoke determination; "I want to see if there really is a hidden shack or a cave here, where they could be hiding out. Then I'd like to learn if they're poachers, snaring the wild game, or the bass up here, and getting it to market on the sly; or some tramps who have been breaking into a store or a bank and are hiding from the constables."

"A bully good place to hide, all right," remarked Davy, as he glanced around at the wild character of their surroundings, and heaved another sigh in contemplation of further scrambling over those sharp-pointed rocks.

"But Thad," put in Smithy, who had been listening all this time without saying a single word, "have you changed your mind about what these strange men may be, since you heard what Davy said about that man at our camp-fire?"

"Well, yes, I am beginning to, right fast," answered the other, frankly.

"You don't think he was as bad as they are, and meant to join them, do you?" continued Smithy, taking an unexpected interest in the matter; for he had observed the party in question closely, as Thad knew, and formed rather a good opinion of him, somehow.

"No, I don't," replied the scout-master, decisively. "If you asked me point-blank what my opinion was, I'd say that he might be a game warden playing a part, or else an officer of the law, looking for yeggmen who have done something that they knew would send them to prison if caught!"

"Whew! just keep right along talking that way, Thad," muttered Davy. "It sure does give me the nicest feeling ever to hear you. Yeggmen now is it, and not just poor game poachers? That's going some, I take it. Say, perhaps they've been and broke into a rich man's place over in Faversham. I happen to know that quite a few city people own cottages there for summer use."
