"If you find that dog—well, never mind," said Dunkan. "I'll promise to do something handsome for both of you."

The boys with their ropes slung over their shoulders, their revolvers in the holsters, strode out of camp waving good-bye to their fellows. They were soon lost sight of.

"Fine boys," averred Ellison.

"Great," agreed Royal.

"The best ever," finished Dunkan.

"What about me?" demanded Chunky.

"Well, I reckon that any fellow who can eat a Pomeranian and get off with nothing more serious than a stomach-ache is copper-lined and brass-riveted," answered Dunkan.

The men soon went about their prospecting work, Professor Zepplin accompanying Jim Dunkan, Walter going out with the other two men, while Chunky remained at camp with Chops. The fat boy decided that he could have more fun teasing the guide and sleeping between times than he could in climbing over the rocks on foot. He could ride all day, but a walk of a mile made him weary.

Tad and Ned, in the meantime, had started out on the trail of the dog and the man, which they had again picked up at the very edge of the camp. Reaching the rocks where the trail had been lost the boys sat down to take a survey of the landscape.

"I think," said Butler, after a few moments of study, "that a person climbing up this way would naturally head for that cut yonder. How far is that from here?"
