With a fine sample of Castillian courtesy and patience, Don Luis
waited, smoking, until Reade had quite finished his inspection.

"I am now at your service, Don Luis," announced the young chief
engineer, rising and going toward his employer.

The remaining four tunnels of _El Sombrero_ Mine were visited. In
each tunnel was the same pile of ore awaiting them, and it all
looked good. That in number three was the richest ore of all.

"Now, I think we have seen enough for today," announced Don Luis,
when they had inspected number three tunnel.

"Then if you will go along and let me join you later, I shall
appreciate it," Tom suggested politely.

"You wish to linger?" queried Don Luis, looking amused.

"I wish to see a blast made here," Tom replied.

"I, too, would like to see one," Harry added.

"Then we will wait for you," agreed Don Luis, with a sigh that
contained just a trace of impatience.

A drilling and a blast were made. Again a lot of poor rock was
loosened. Tom and Harry collected specimens, labeling them.

"Now, we will return to the house," said Don Luis.
