"What did I say to you, Don Luis?" inquired the secretary. "Did
I not suggest that these Gringos would not be easily controlled?"

"Wait!" advised Don Luis Montez. "Wait! You have not yet seen what
my Gato will do. He is not a baby."

"These Gringos will balk at every hour of the day and night,"
predicted Dr. Tisco.

"Wait until you have seen my good Gato tame them!" chuckled Don
Luis, softly.

CHAPTER III

GATO STRIKES THE UP TRAIL

"When you speak to me, Gringo," bellowed Pedro Gato, "you will--"

"Stop, Greaser!" shot back Tom, sternly, though he did not even stir
or raise his hands.

"Greaser?" bellowed Pedro Gato. "That is foul insult!"

"Not more so than to call me a Gringo," Tom Reade went on coolly.
"So we are even, though I feel rather debased to have used such
a word. Gato, if you make the mistake, again, of using an offensive
term when addressing me, I shall--well, I may show a somewhat
violent streak."

"You?" sneered Gato. Then something in the humor of the situation

I am not usually as disagreeable as this in dealing with my fellow

you'll have to learn to do will be to treat us with proper courtesy."

From the shaft entrance showed the faces of four grinning, wondering
Mexicans of the usual type. The talk had proceeded in Spanish, and
they had been able to follow it.

As for the mine manager, his bronzed face was distorted with rage.
The veins near his forehead were swelling. With a sudden roar,
Pedro Gato sprang forward, aiming a blow with his open right hand
at Reade's face.

Bump! That blow failed to land. It was Gato, instead, who landed.
He went down on his back, striking the ground with jarring force.

"What did I say?" whispered Dr. Tisco.

"Wait!" responded Don Luis, with a shrug of his shoulders.

Well-nigh frothing at the mouth, Pedro Gato leaped to his feet.
All was red now before his eyes. He rushed forward bellowing
like a bull, intent on crushing the young American who had dared
to treat him thus.

Tom's left fist drove into the fellow's unguarded face. His right
followed, and Gato, big as he was, staggered back. Tom's right
foot performed a trip that sent
