It was autumn--late autumn--that loveliest season of the American year, when the wild woods appeal painted, and Nature seems to repose after her annual toil--when all her creatures, having feasted at the full banquet she has so lavishly laid out for them, appear content and happy. It was night, with an autumnal moon--that moon whose round orb and silvery beams have been celebrated in the songs of many a harvest land. Not less brilliant fell those beams where no harvest was ever known-- upon the wild plain of the Llano Estacado. The lone _hatero_, couched beside his silent flock, was awakened by a growl from his watchful sheep-dog. Raising himself, he looked cautiously around. Was it the wolf, the grizzly bear, or the red puma? None of these. A far different object was before his eyes, as he glanced over the level plain--an object whose presence caused him to tremble. A long line of dark forms was moving across the plain. They were the forms of horses with their riders. They were in single file--the muzzle of each horse close to the croup of the one that preceded him. From east to west they moved. The head of the line was already near, but its rear extended beyond the reach of the hatero's vision. Presently the troop filed before him, and passed within two hundred paces of where he lay. Smoothly and silently it glided on. There was no chinking of bits, no jingling of spurs, no clanking of sabres. Alone could be heard the dull stroke of the shoeless hoof, or at intervals the neigh of an impatient steed, suddenly checked by a reproof from his rider. Silently they passed on--silent as spectres. The full moon gleaming upon them added to their unearthly appearance! The watcher trembled where he lay--though he knew they were not spectres. He knew well what they were, and understood the meaning of that extended deployment. They were Indian warriors upon the march. The bright moonlight enabled him to distinguish farther. He saw that they were all full-grown men--that they were nude to the waist, and below the thighs--that their breasts and arms were painted--that they carried nought but their bows, quivers, and spears--in short, that they were braves _on the war-trail_! Strangest sight of all to the eyes of the hatero was the leader who rode at the head of that silent band. He differed from all the rest in dress, in equipments, in the colour of his skin. _The hatero saw that he was white_! Surprised was he at first on observing this, but not for long. This shepherd was one of the sharpest of his tribe. It was he who had discovered the remains of the yellow hunter and his companion. He remembered the events of that time. He reflected; and in a few moments arrived at the conclusion that the _White Chief_ he now saw could be no other than Carlos the cibolero! In that conjecture he was right.
