Parallel to the line of the cliffs, and close in to their base, a horseman could be seen advancing up the valley from the lower end of the settlement. His cautious pace, and the anxious glances which he at intervals cast before him, showed that he was travelling with some apprehension, and was desirous of remaining unseen. It was evident, too, that this was his object in keeping within the shadow of the cliff; for on arriving at certain points where the precipice became slanting and cast no shadow, he would halt for a while, and, after carefully reconnoitring the ground, pass rapidly over it. Concealment could be his only object in thus closely hugging the bluffs, for a much better road could have been found at a little distance out from them. After travelling for many miles in this way, the horseman at length arrived opposite the town, which still, however, was three miles distant from the cliff. From this point a road led off to the town, communicating between it and a pass up the bluffs to the left. The horseman halted, and gazed awhile along the road, as if undecided whether to take it or not. Having resolved in the negative, he moved on, and rode nearly a mile farther under the shadow of the bluffs. Again he halted, and scanned the country to his right. A bridle-path seemed to run in the direction of the town, or towards a point somewhat above it. After a short examination the horseman seemed to recognise this path as one he was in search of, and, heading his horse into it, he parted from the shadow of the bluffs, and rode out under the full moonlight. This, shining down upon him, showed a young man of fine proportions, dressed in ranchero costume, and mounted upon a noble steed, whose sleek black coat glittered under the silvery light. It was easy to know the rider. His bright complexion, and light-coloured hair curling thickly under the brim of his sombrero, were characteristics not to be mistaken in that land of dark faces. He was Carlos the cibolero. It could be seen now that a large wolf-like dog trotted near the heels of the horse. That dog was Cibolo. Advancing in the direction of the town, the caution of the horseman seemed to increase. The country before him was not quite open. It was level; but fortunately for him, its surface was studded with copse-like islands of timber, and here and there straggling patches of chapparal through, which the path led. Before entering these the dog preceded him, but without noise or bark; and when emerging into the open plain again, the horseman each time halted and scanned the ground that separated him from the next copse, before attempting to pass over it.
