Jimmie noted the look and took out his field glass. People were moving about in the canyon, and down in the valley to the south, where the cabin stood, something out of the ordinary seemed to be going on.
"You are expecting friends?" asked Frank.
"They are liable to come any minute," was the cool reply.
"Then we'd better be going," Jimmie cut in. "There are men in the canyon, and in the valley, and they may be coming up here to find out why you don't meet them, as per agreement! Are they good waiters? If they are, you may find them still in the valley after you've served a couple of terms in a Federal prison!"
"Be careful what you say," warned Bradley. "I'm in your power now, but there'll come a time when I won't be. Remember that!"
Jimmie's glass showed him that the men below were starting up the slope.
"We'll go back toward camp," he said to Frank. "I guess the fellows down there are watching us through glasses. If you don't mind," he added, turning to Bradley with a provoking laugh, "we'll stow you away in a hole in the rocks somewhere until they get tired of looking for you!"
"Go as far as you like!" was the reply.
Frank and Jimmie stepped aside and conversed together in low tones, trying to make up their minds what to do with the prisoner. It had taken little trouble to capture him, but it seemed to them that it would be no easy matter to hold him.
"There's a cute little dip in the summit not far from the camp," Frank said, at length. "A boulder tumbled out of the slope, and there's a cave big enough to hide three in, only there is a part of it which has no roof."
