My belief in the supernatural was of short duration, how long I know not, for during its continuance I remained in a state of bewilderment.
My senses at length returned. My eyes had fallen upon a fresh hoof-print on the turf, directly in front of me. I knew it was that made by the white steed, and this awoke me to a process of reasoning. Had the horse been a phantom, he could not have made a track. I had never heard of the track of a ghost; though a horse-ghost might be different from the common kind!
My reflections on this head ended in the determination to follow the trail as far as it should lead; of course to the point where the steed must have mounted into the air, or evaporated—the scene of his apotheosis.
With this resolve, I gathered my reins, and rode forward upon the trail, keeping my eyes fixed upon the hoof-prints.
The line was direct, and I had ridden nearly two hundred yards, when my horse came to a sudden stop. I looked out forward to discover the cause of his halting; with that glance vanished my new-born superstitions.
At the distance of some thirty paces, a dark line was seen upon the prairie, running transversely to the course I was following. It appeared to be a narrow crack in the plain; but on spurring nearer, it proved to be a fissure of considerable width—one of those formations known throughout Spanish America as barrancas. The earth yawned, as though rent by an earthquake; but water had evidently something to do with the formation of the chasm. It was of nearly equal width at top and bottom, and its bed was covered with a débris of rocks rounded by attrition. Its sides were perfectly vertical, and the stratification, even to the surface-turf, exactly corresponded—thus rendering it invisible at the distance of but a few paces from its brink. It appeared to shallow to the right, and no doubt ended not far off in that direction. Towards the left, on the contrary, I could see that it became deeper and wider. At the point where I had reached it, its bottom was nearly twenty feet from the surface of the prairie.
Of course, the disappearance of the white steed was no longer a mystery. He had made a fearful leap—nearly twenty feet sheer! There was the torn turf on the brink of the chasm, and the displacement of the loose stones, where he had bounded into its bed. He had gone to the left—down the barranca. The abrasion of his hoofs was visible upon the rocks.
I looked down the defile: he was not to be seen. The barranca turned off by an angle at no great distance. He had already passed round the angle, and was out of sight!
It was clear that he had escaped; that to fellow would be of no use; and, with this reflection, I abandoned all thoughts of carrying the chase farther.
After giving way to a pang or two of disappointment, I began to think of the position in which I had placed myself. It is true I was now relieved from the feeling of awe that, but a moment before, had oppressed me; but my situation was far from being a pleasant one. I was at least thirty miles from the rancheria, and I could not tell in what direction it lay. The sun was setting, and therefore I had the points of the compass; but I had not the slightest idea whether we had ridden eastward or westward after leaving the settlements. I might ride back on my own trail; perhaps I might: it was a doubtful point. Neither through the timber, nor on the open prairie, had the chase gone in a direct line. Moreover, I noticed in many places, as we glided swiftly along, that the turf was cut up by numerous hoof-tracks: droves of mustangs had passed over the ground. It would be no easy matter for me to retrace the windings of that long gallop.
