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.
"I would really like to put in a long day here at the mine," proposed
Reade, reluctantly.
