The cibolero, on gaining the ground, pointed out the spot where he had proposed to execute his daring design. From the plain above the cliffs were not visible, and even the great abyss of the valley itself could not be seen a hundred paces back from the edge of the bluff. There was no escarpment or slope of any kind. The turf ran in to the very edge of the precipice, and on the same level with the rest of the plain. It was smooth and firm--covered with a short sward of _gramma_ grass. There was neither break nor pebble to endanger the hoof. No accident could arise from that cause. The spot chosen, as already stated, was a sort of buttress-like promontory that stood out from the line of bluffs. This formation was more conspicuous from below. Viewing it from above, it resembled a tongue-like continuation of the plain. Carlos first rode out to its extremity, and carefully examined the turf. It was just of the proper firmness to preclude the possibility of a horse's hoof either sliding or sinking into it. He was accompanied by Vizcarra, Roblado, and others. Many approached the spot, but kept at a safe distance from the edge of the horrid steep. Though denizens of this land of grand geological features, there were many present who dreaded to stand upon the brow of that fearful ledge and look below. The cibolero sat upon his horse, on its very edge, as calm as if he had been on the banks of the zequia, and directed the marking of the line. His horse showed no symptoms of nervousness. It was evident he was well-trained to such situations. Now and then he stretched out his neck, gazed down into the valley, and, recognising some of his kind below, uttered a shrill neigh. Carlos purposely kept him on the cliff, in order to accustom him to it before making the terrible trial. The line was soon traced, less than two lengths of the horse from the last grass on the turf. Vizcarra and Roblado would have insisted upon short measure; but their proposal to curtail it was received with murmurs of disapprobation and mutterings of "Shame!" What did these men want? Though not evident to the crowd, they certainly desired the death of the cibolero. Both had their reasons. Both hated the man. The cause or causes of their hatred were of late growth,--with Roblado still later than his Comandante. He had observed something within the hour that had rendered him furious. He had observed the waving of that white kerchief; and as he stood by the stand he had seen to whom the "adios" was addressed. It had filled him with astonishment and indignation; and his language to Carlos had assumed a bullying and brutal tone.
