A short time later they were in their room.

"You don't suppose now, Frank, that we'll be bothered to-night?" Bob observed, as he stood there by the window looking out toward the Grand Canyon.

At that the other laughed quite merrily.

"Don't give yourself any uneasiness about that, Bob," he remarked. "In the first place nobody would bother trying to get up here, even if they could, when so many better chances of reaching us will crop up after we start into the canyon to-morrow. Then again, we haven't anything to be stolen but our rifles, and what little cash we brought along for expenses."

"Oh! I suppose I am silly thinking about it," admitted Bob, "but some way that half-breed seems to be on my nerves. His face is so sly, and his black eyes just glitter as I've seen those of a snake do when he's going to strike. But, just as you say, it's foolish to borrow trouble, and I must get those notions out of my head."

"That's the talk, Bob," his chum declared, heartily. "Morning will find us in fine trim to make a start into this big ditch. And before another night you'll be so filled with wonder over what you see that these other things will take a back seat."

"But do you think we ever can find the hermit of Echo Cave?" asked Bob.

"I think we've got a pretty good chance, if we're left alone," came the ready reply.

"Meaning if this Eugene Warringford keeps his hands off; and nothing else turns up to balk us?" Bob asked.
