I feel very certain that I must have made it very clear to you yesterday that I could not possibly sign any such report at the present time.
I still prefer to keep our talk within the limits of courtesy if that be also your wish." "Sign that report!" "_I won't do it!_" Tom accompanied his response by tossing the pen across the room.
"Don Luis, I don't believe that you are a fool," continued the young chief engineer, calming down again.

"If you consider that I am utterly a fool, either, then you are doing your own intelligence an injustice.

I refuse to sign this report until I have gained the knowledge for myself that every word in it is true.

Further, I don't believe that I would sign it after I had made the fullest investigation.

I am aware that, last night, mule-trains brought ore down over the hills from another mine, and that ore was sent down by the ore hoists into _El Sombrero_." "That's a lie!" cried the Mexican, hoarsely.
"I am describing what I saw with my own eyes," Tom insisted.
"You will sign this report, and at once!" quivered Don Luis Montez, a deadly look glittering in his eyes.
"I am quite satisfied that I shall never sign it," Tom retorted.
"That goes for me, too," put in Harry, stolidly.
"I feel that we have finished our work here, since we can do nothing more for you, Don Luis," Tom went on.
