"Oh, I'll wager the poor peons at the mine have been at work for some time," Tom smiled. "Anyway, I'm glad we haven't kept everyone else waiting."

At half-past ten o'clock Dr. Tisco appeared, immaculate in white.
He bowed low and courteously to the guests.

"I trust, caballeros, that you have enjoyed perfect rest."

"Yes," answered Harry. "And now we're fidgeting to get at work. But, of course, we can't start for the mine until Don Luis gives us the word, and we are at his pleasure."

"It is nearly time for Don Luis to appear," said Tisco gravely.

"Is he always as late as this?"

"Here, Senor Hazelton, we do not call eleven o'clock a late hour for appearing."

Twenty minutes later Don Luis appeared, clad in white and indolently puffing at a Mexican cigarette.

"You will smoke, gentlemen?" inquired their host, courteously, after he had inquired concerning their rest.

"Thank you," Tom responded, pleasantly. "We have never used tobacco."
