Fortunately, behind the office of the mine, there was a small room well stocked with rifles and ammunition. This was wise precaution of Mr. Merrill's, who, knowing the Mexican character to a T, had insisted on this room being provided in case of strikes or other difficulties.

The store of arms was drawn upon freely, and each of the defenders had a spare rifle at his side. The weapons were piled by their respective holes while the besieged awaited the attack. But a hasty dinner was prepared on the coal-oil stove Of the office, and eaten and digested before there came any move on the part of Madero's men.

Through the peep-holes a casual inspection showed nothing outside but the hillside sloping away from the mine, with here and there a clump of bushes or small, scrubby trees. But every once in a while the grass would stir, or a clump of bushes would be agitated strangely, as some concealed form crept up yet closer to the stockade. Evidently, as Buck had said, the intention of Madero was to "rush" the place.

The mining village now seemed deserted, except for a few forms of women and children which could be seen flitting about. Evidently most of the men had joined the insurrectos, hoping to have a share in the loot when the time came.

"Say, Geisler!" exclaimed Buck Bradley suddenly, "got any steam in the boiler?"

"Ches. Aboudt forty or fifty pounds. Der fires vos banked. Pud vy?"

"Oh, nothing. I've just got a little plan in my head. Now, Jack, suppose you and I take a little run to the boiler room and look about us a bit."

The boy was glad of anything to do to relieve the tension of waiting for the attack that didn't come. He gladly accompanied the self-reliant Westerner to the boiler house. They found, as Geisler had said, that in one of the boilers steam was still up.

"Now let's take a look around here, sonny," said Buck, glancing about the walls as if in search of something. "Ah! Here we are, that will do."

He pounced on a big reel of fire hose attached to the wall, as he spoke.
