It was an easy matter to climb down the mountain side, but the walk up the hill that separated them from the lake was another story. Yet, as they had only their guns to carry, they made good progress, and by the middle of the afternoon they were in plain sight of the body of water where they had left the boat.

"Somebody ahead of us!" cried Snap presently, and pointed out three persons walking toward the lake.

It was presently made evident to our friends that the persons ahead were Ham Spink, Carl Dudder and a lad named Dick Bush, who had in former years been a close personal friend to Ham.

"Wonder where they are going?" asked Snap.
