Then as he lay there waiting until the drowsiness overtook him again, he allowed his fugitive thoughts to once more wrestle with the mystery connected with the late occupants of that birch bark cabin. Who could they be, and whither had they flown at the approach of himself and three chums?

It was hardly any accident, for all the signs pointed to a flight that bordered on panic. Whoever they were they must have some good and sufficient reason for fearing the advent of strangers. That could only mean they dreaded the strong arm of the law; that there was some reason why they wished to keep from contact with all whom they did not know.

Well, Phil concluded, there was no use of bothering about them. They had taken a hurried departure, and that was the end of it. He had reason to believe that a child had been there, and possibly a woman as well. While they had not found such tell-tale evidence as a hair-pin, still the little silver thimble which he himself had discovered on a shelf just before retiring, and which he had not mentioned to the others, because he hated to get Lub wide-awake again, seemed to be pretty strong evidence that way.

When he found himself yawning again Phil decided it was time he closed his eyes, and allowed his senses to steal away. The fire had ceased flaring up, and was dying out rapidly, though the ashes would likely retain some of their heat until well on toward dawn.

The last Phil remembered was listening to the weird call of that persistent whip-poor-will, perched in some neighboring tree, and sending forth its shrill discordant cries.

Twice after that he awoke, and found all well. He could hear the steady breathing of his comrades near by; and Lub, lying flat on his back perhaps, was making a grating noise not unlike a snore.

The second time Phil struck a match, one of the silent kind, and took a look at his watch, curious to know how the night was wearing away. He found it was two o'clock, and that the guess he had made was not far amiss.

It took him some little time to get asleep again after that, but in the end he managed to accomplish it. Daylight would be coming by four o'clock and as the novelty of the outing was still upon them, it was to be expected that the boys would want to be up with the birds—that is, all but Lub, who loved sleeping better than plunging into the lake for an early morning swim.

It was fated, however, that they were not to be allowed to slumber calmly on until the approach of the sun hurried the round moon out of sight below the western horizon.

A most unearthly racket sounding awoke every one. If an earthquake had occurred it could hardly have created a greater noise. And the big frying pan proved that the supreme confidence which Lub had placed in its ability to jangle had not been in the least overdone; for it certainly played a fandango as it pitched over on the hard floor of the cabin, and danced some sort of jig, with other things adding their little mite to swell the chorus.
