At the opposite end of the shack, in a shutter, was pierced a peephole that commanded a view of the door of the shack that the boys believed was the one used by the occupant or occupants of the building.

"There, everything is set. You chaps hike, and then Dick is to return at noon to relieve me, leaving Phil the first watch tomorrow morning," ordered Garry.

Garry's watch was unavailing, for when Dick came at noon he had nothing to report. It was arranged that no one should come for Dick, but that he should be back as soon after dusk set in as possible. In order to be sure of Dick's safety, it was agreed that if he were not back by eight o'clock the others should come and see what was up, or if anything was the trouble.

Dick turned up at the lean-to just as dark set in, and reported that there was nothing stirring.

The boys were almost of the opinion that the whole business was a wild goose chase, but Phil was determined to take a hand at watching, and it was agreed that he should stand the morning watch, and be joined at noon by the others, who would finish the day together.

In case nothing developed they would put an end to the watching and start for Umculos Lake the following morning.

Phil started for his post the next morning. As he went, he said:

"I've a hunch something breaks this morning, hope my hunch comes true."

He had been gone not much more than an hour when he came tearing back, just catching the others as they were setting out on a short hike into a new and unexplored part of the woods.

"The mysterious occupant has come, and guess who it is!" he shouted.
