rub to help him, Billy crept
quickly to the top.

"Still, we don't know just where Dave may have run in. It's queer that
he let the scow drift, if--even if he expected to go right back," said
Worth in a hushed tone, from the edge of the low bluff.

"Queer what became of the man who called him over here, if such a thing
as Mac falling into the water may have happened," observed Phil. "And
Dave could swim--why, almost across the lake, if he had to! He could save
himself if there was nobody pulling him down."

Throwing Billy a line by which to hold the boat, Way and Slider followed
him up the bank. They walked some distance in each direction along the
shore but the feeble light of the oil lamps showed no trace of David
MacLester nor yet of the mysterious person who had summoned him. The
thought, "crooked work," was in the minds of all three.

"After all, it's the water I'm most afraid of. If Dave fell and hurt
himself or was pushed into the lake--but never mind. One of us must go
back to Paul and the others will have to--look further," said Phil at last.

Billy was chosen to return to camp. What Phil meant to do, with Slider's
help, was drag the lake in this vicinity. If Dave had gone to the bottom,
due to some accident or injury, it might not yet be too late to save his
life. Such things had been done, Way said, but he spoke without his usual
confidence and very, very gloomily.

Returning to the skiff, the boys ran along side the fishing boat and drew
the latter to shore. Phil and Chip tied her to a projecting root and Worth
bade them good-bye.

With a long, steady stroke he pulled for the southern shore and the bright
light blazing there. But it is one thing to row for the fun of it, when
the sunlight dances on the ripples, and quite another to cross a strange
body of water--and alone--when inky darkness spreads everywhere.

The swelling of the wood had now pretty well stopped the skiff's leaking,
yet again and again Billy paused to bail out. The unpleasant thought
that he would find the water pouring in too fast for his best efforts
harassed him. He could not see, so he often put down his hand to feel
and thus make sure the boat was not filling. So at last did he float
into the rays of the campfire's light and a minute later stand telling
Paul the unhappy discoveries made.

The thought that Dave and the strange man, having found their boat
drifting beyond reach, may have started to walk around the head of the
