"Yes, I had noticed that some one had certainly thrown water on the fire," said Phil. "You can see where it washed the ashes off this charred piece of wood; and besides, it made little furrows in the ashes."

"That's an old trick in the woods," remarked Ethan, with a superior air; "fact is, no true woodsman would think of breaking camp without first making sure every spark of his fire was put out. Lots of forest fires have come from carelessness in guides leaving red cinders behind them."

"Yes," Phil added, "because often the wind rises, and whirls those same cinders to leeward, where they fall in a bunch of dry leaves, and begin to get their work in. But when people live in cabins they seldom bother wetting the ashes, unless they've got a mighty good reason for wanting to hide the facts."

"And these people did," added Ethan, conclusively.

"Let's look around some," suggested X-Ray.

Two of the others thought this a good idea, for they immediately started a search of the interior of the cabin, their idea being to find some clue that might tell just who the late mysterious inmates were, and why they had fled so hurriedly.

Lub may have been just as curious as his mates; but he was very tired after the long and arduous walk, so that apparently he believed three could cover the field just as thoroughly as four. At any rate he showed no sign of meaning to quit his seat upon the rude stool he had found; but leaning forward, watched operations, at the same time rubbing his shins sympathetically.

"What's this on the peg up here?" exclaimed X-Ray, the very first thing.

"Looks like some sort of a hat to me," remarked Ethan.

"Just what it is; but say, take notice of the size, will you? It's a child's hat, as sure as you live! Why, there must have been a child along with the lot!"
