That Jim was correct in his surmise was shown later when Bob and Sam turned their craft into the stream which led to Round Lake, and then landed, evidently for the night.
"How near shall we go to them?" Jim asked.
"It won't do to stay too far away, for we must make it appear as if we intended to run down the same stream. We'll hold up here."
Jet steered the craft into an indentation on the shore about a quarter of a mile from where the others had stopped, and at a spot from which he could keep them in view.
"I'll rig up a camp, and you keep your eyes on them while you're getting some of the grub out," the small guide proposed.
The boys made preparations for the night, and while so occupied could see that the men were doing the same.
Then fires were lighted in both camps, and Jet watched the one down stream until his eyes closed in slumber, despite all his efforts to keep them open.
The gray light of dawn could be but faintly seen in the eastern sky when the amateur detective awakened, and his heart was made glad by the sight of a glow from the lower encampment.
"They haven't started yet," he said, as he awakened the guide, "and it stands us in hand to be ready to leave the minute they do."
"Better let 'em get to the carry first. When they keep on down the stream, we'll know where they're headed for, an' can get through in time, for I don't reckon there's a chance of their stayin' on Round Lake."
