The study continued only a few minutes, when he came back and handed the glass to the youth, with the remark: "I'm going to try it agin.

I won't expect to see you till to-morrer morning." The lad bade him good-by, and he took his departure; but instead of descending the mountain toward the point that had interested him, he followed the opposite course, as if he intended to push through to the other side of the Wind River range.

This was so transparent a subterfuge that it did not deceive Jack.
"He has discovered something," was his conclusion; "he doesn't choose to tell me, and it makes little difference.

I wonder whether he believes I intend to idle my time till night and then go back to headquarters and wait for him?
If he thinks so, he makes a mistake." Waiting until sure his friend was beyond sight, Jack carefully picked his way to the rock from which Hank had made the observation that decided his line of action.

The better to screen himself the youth lay down on his face, as when peering over the ridge into the valley where the antelope were grazing, and held the glass to his eyes.
Thus looking out, he saw the plateau in the distance, seemingly but a few rods in extent.
