"For many reasons," whispered Dr. Tisco, "let Gato go. For either good or bad reasons it will be best to let him go."

"You are right, Carlos," nodded the mine owner quickly. Then, raising his voice:

"My good Gato, you shall have your wish," he went on, in his purring tone. "Yet do not think there is anger behind my words. I let you go because it is your wish. I do not so decide that I may humiliate you, but because you have served me well. When you need a friend, Gatito, you will know to whom to send word. Go your way in friendship."

Even Tom Reade, with his somewhat scant knowledge of Spanish, was quick to note, mentally, the meaning of that term, "Gatito," which meant "little Gato," and was used as a term of affection. It was a form of telegraphy that was not wasted on the departing mine manager, either, for it told him that Don Luis had some excellent reason for thus quickly falling in with the wishes of the new American chief engineer.

With a grateful smile at Don Luis, then with a scowl of unutterable hatred flung in Tom Reade's direction, Pedro Gato next turned on his heel and strode up the path.

From his pocket Harry Hazelton drew forth the silver-mounted revolver and approached the owner of the mine.

"Allow me to return this to you, Don Luis," urged Hazelton. "I must also apologize for having snatched it from you so rudely. I did not know what else to do, for I feared that you intended to interfere in the quarrel."

"And what if I had so intended?" asked the Mexican mine owner, with one of his puzzling smiles.

"Just this," Harry answered, candidly. "Mr. Reade never gets into a fight if he can help it. When he does find himself in one I have learned, from long experience, not to interfere unless he calls for help. So I did not want any one to interfere between him and Gato."

"It was a most unfortunate affair," said the Mexican. "Senor Tomaso, I must warn you that Pedro Gato is one who never forgives an injury. He will devote himself to thoughts of a revenge that shall be terrible enough to satisfy his wounded feelings. You will do well to be on your guard."
