“I reckon so,” admitted Jerry.

“Let him dog!” exclaimed Bob. “He daren’t come up here and try to get into your mine, dare he, Tinny?”

“No, he can’t trespass on Leftover if I know it.”

“What’s Leftover?” Jerry wanted to know.

“It’s what I call the mine,” explained Mallison. “It was part of a claim left over when some prospectors divided their holdings. It wasn’t considered of much value, and I got it cheap. So I called it Leftover. Then I discovered a new vein that no one had suspected. I needed help to work it, and that’s why I sent for you boys. But we’ll go into all that in the morning. I hope you’ll like Leftover.”

The boys did. When they looked about the next day after a restful night of sleep they were more favorably impressed with the place than they had been before. As might have been expected, Professor Snodgrass soon after breakfast started out to gather specimens. The boys, with Tinny and Bill Cromley, went to the mine.

“Don’t get lost!” called Mallison to the professor.

“Oh, I can find my way back,” he asserted.

Leftover mine had not really been worked at all. The former owners had driven in a short tunnel. Tinny had started another, in which he had soon come upon richer signs than the former owners had discovered. It was to his tunnel that the prospector took the boys.
