"That's queer!" Lub observed, not wanting to be wholly ignored.

"Game poachers they may have been," muttered Ethan, "but if there was a little chap along, there must have been a family of 'em. See if you could pick up such a thing now as a hair-pin, or any other woman business."

They went to scrutinizing the cracks of the floor more closely than ever. That suggestion on the part of Ethan was worth trying out. Of course the presence of any little article like a hair-pin would show that a woman had been there.

"I don't hear anybody sing out!" remarked X-Ray Tyson, presently; "and on that account it looks like we hadn't discovered anything worth mentioning. What gets me is, however could they have cleaned the old shack out so quick, and never left anything worth mentioning behind 'em?"

"From the time we sighted the cabin, back to when we first whooped, couldn't have been more'n eight minutes, I should think," Lub gravely announced.

"Lots could be done in that time," asserted Phil; "but all the same I am bothered to know why they'd be in such a rattling big hurry. It might be they knew about us being on the way longer than eight minutes."

"Who would have called 'em up on the phone, and mentioned the fact?" asked X-Ray, meaning to be humorous.

"Well, one of the lot may have seen us miles back, and put for the cabin by some short-cut we don't know anything about," Phil told him.

"That could be, of course," admitted Ethan, after considering the matter seriously.

"Mebbe we'll never know the truth, which would be too bad," Lub continued; for a mystery was a source of constant anxiety to him; he was so frank and straightforward himself that double dealing seemed foreign to his nature.
