"Then I'll take it," decided the guide, dismounting and stowing the abandoned piece of glass in his saddle bags.

"Bottles are good for only two things."

"And what are they, Master Stacy?" questioned the Professor.

"To keep things in and to shoot at," replied the fat boy wisely.

Everybody laughed at that.

"I guess that embodies everything you can say about bottles," smiled the Professor. "Your logic, at times, young man, is unassailable."

Chunky nodded. He had a faint idea of what Professor Zepplin meant.

Late that afternoon the travelers came upon a shack in the foothills, where an old rancher, a hermit, lived when not tending his little flock of sheep, most of which, Kris Kringle said, the old man had stolen from droves that came up over the trail going north.

He was an interesting old character, this hermit, and the boys decided that they would like to make camp and have him take supper with them. This the Professor and the guide readily agreed to, for everyone was hot and dusty and the bronchos were nervous and ill-natured.

The boys found the old rancher talkative enough on all subjects save himself. When Chunky asked him where he came from, and what for, the old man's face flushed angrily.
