Jose swung a dishpan, grinning broadly, while the Professor smiled and nodded at the departing horsemen. In a few moments the voices of the boys had become only a distant murmur.

"Come into my tent a moment, Mr. Tackers," invited the Professor.

The old mountaineer accepted the invitation apparently somewhat grudgingly.

"I hear considerable about gold being found in this neighborhood, occasionally, Mr. Tackers. What has been your experience, may I ask?"

"There's some as has found pay dirt," answered Ben. "But I reckon Ben
Tackers don't bother his head about it."

"Hm-m-m-m," mused the Professor. "What is the nearest railroad station to this place?"

"Eagle Pass. 'Bout twenty miles from here, due east."

"How long would it take you to make the trip there and back?"

"Wouldn't make it again. Just been there. Haven't any horse."

"I have a horse, Mr. Tackers, and I should very much like to have you make this trip for me," announced the Professor, coming directly to the point. "I will pay you well for your trouble, but with the understanding that you say nothing of it to anyoue. The errand on which I am asking you to go is a confidential one. You will not mention it even to Lige Thomas. And, of course, it goes without saying that I do not wish the boys to know about it, either."
