"Gato is no longer with us, and these gentlemen are in charge." "Then I will have the ore moved back at once," agreed the foreman.
"But first we will go back out of the dirt and out of the danger from the blast," spoke Don Luis, using a good deal the tone of an order.
"The rest of you may go back," suggested Reade.

"But I wish to see the drilling done." "It is unnecessary, Senor Tomaso," smiled Don Luis, blandly.
"Come back with us." "I must see the men work, Don Luis, if I am to understand the work here," Tom rejoined, very quietly, though with a firmness that was wholly apparent.
"Oh, very good then," smiled Montez, with a shrug of his shoulders.
Three of the inspecting party went back, but Tom remained close behind the drillers.

Twice he stopped them in their work, to collect small samples of the pulverized stuff that the drills turned back.

These specimens he placed in sample envelopes and stored in his pockets.

From the ore that was being shoveled back he chose other small specimens, labeling the envelopes in which he stored them.
By the time that the ore had been shoveled well back the drillers had completed their work.
