"Blamed if I know; might be a mere row—hold on, there! Whoever did it is in that cabin; watch what they're up to, now."

The three hung there scanning every movement of those below, too intently interested to talk, yet unable for some time to determine clearly what was impending. Occasionally the sound of a voice reached them, shouting orders in Spanish, and men came and went in obedience to the commands. More guns were brought forth from the bunk-house, and distributed; the single horseman rode swiftly up the valley, and a half-dozen of the fellows lugged a heavy timber up from the corral, and dropped it on the ground in front of the smaller cabin. Mendez, his arm in a sling, passed from group to group, profanely busy, snapping out orders.

"They are going to break in the door with that log!" muttered Westcott between his clenched teeth. "That white-head down there is boiling with rage, and whoever the poor devil, or devils, may be, they'll have to fight."

"Yes, but who are they?" and Brennan sat up. "The whole gang must be outside there; I counted fourteen. Then, did you notice? Mendez had his hands bound behind his back. He couldn't even get up until those fellows untied him. That's what puzzles me."

"It would take more than one to do that job. Maybe we'll find out now—he's pounding with a revolver butt on the front door."

They listened breathlessly, hanging recklessly over the rim of the chasm, and staring at that strange scene below, but the man's words only reached them broken and detached. They got enough, however, to realise that he demanded the unbarring of the door, and that he both threatened and promised protection to whoever was within. It was the language he employed that aroused Westcott.

"Did you hear that?" he asked shortly. "The man spoke English. Whoever's in there doesn't understand Spanish. Were any Americans down there when you left, Moore?"

"Joe Sikes, and a fellow they call 'Shorty,' but they're both outside; that was Joe who bound up ol' Mendez's arm, an' Shorty was helpin' bring up the log."

The eyes of Brennan and Westcott met understandingly.

"Yer don't suppose that girl——"
