It will be remembered that the darkness was more dense in the mesquite bush than on the open prairie, and, although he caught a glimpse of the vanishing mustang, he saw nothing of the figure on his back, for the reason that, when the nimble youth vaulted thither, he threw himself forward on his neck. The Indian must have been astonished by the action of his animal, but he probably concluded he would not wander far, and would be within reach in the morning when needed. So he refrained from attempting anything like pursuit, which would have been foolish under the circumstances. It was a clever exploit on the part of Avon Burnet, and he could not repress a feeling of exultation over the success. Boldness, dash, and peculiarly favoring circumstances had taken him through the Comanche lines, when a repetition of the attempt would fail ninety-nine times out of a hundred. But while he was justified in being grateful, there was enough serious business still before him. He could not forget that the friends in the cabin were in dire peril and no time ought to be wasted in bringing them relief. The first indispensable act was to locate himself, so as to gain an idea of the points of the compass, without which it was beyond his power to reach the camp of his friends. A brief walk brought the horse out of the bush and he stood on the open prairie. The mustang was without saddle or bridle, except a single buffalo thong, that was twisted over his nose and by which his master guided him. Avon had ridden the animals in the same way, and since this mustang became tractable the instant he felt anyone on his back, such an equestrian as the young Texan met with no difficulty whatever. But he realized that a serious difficulty confronted him when he attempted to locate himself. The flurry in the bush had so mixed up his ideas of direction, that he was all at sea. Not a star twinkled in the cloudy sky, nor could he tell in what quarter of the heavens the moon was hidden. Looking in the supposed direction of the cabin, he saw only gloom, while it was equally dark when he gazed toward the spot where he believed the camp of the cowboys lay. Between the home of Captain Shirril and the spot where his men awaited his coming were several elevations and depressions of land, so that had the Texans been burning a fire, as was likely, it would not show until more than half the intervening distance was passed. The cattle were herded to the northward, so that in the event of a stampede it was easier to head them on the right course over the Great Cattle Trail. A person placed in the situation of young Burnet is apt to go astray, no matter how extended his experience in wandering abroad at night, unless he is able to start right. This was the difficulty with Avon, who was too wise to depend upon what impressions took possession of him, since it is almost the invariable rule that such impressions are wrong.
