Kit Carson still remained upon the outer flank and once he discharged his rifle, an act which, as Reuben believed, was intended only to frighten the horses. If that had been the hunter’s purpose it was easily achieved, for the speed at which the drove was running quickly increased. At the same time it was equally clear to the leader that he had been unable to shake off the enemy that was pursuing him.

Shouting still more loudly and persistently increasing the swiftness of his pursuit, Kit Carson succeeded in steadily pressing the horses to his right and at the same time compelling them to move much more rapidly.

Reuben’s excitement increased as the band steadily drew nearer the place where he was awaiting their approach. As yet Kit Carson had not succeeded in separating the black horse from his companions. It was not until the hunter drew near the place where Reuben was hiding that he suddenly, with a renewed shout and a second discharge of his gun, dashed swiftly in between the leader and the drove. Again shouting in his loudest tones, he forced the startled animal southward and at the same time glanced all about him, evidently expecting Reuben to appear.

Only a few moments elapsed before Reuben decided that the time had come for him to join in the chase. He dashed forth from behind the sheltering rock and, urging his horse into its swiftest paces, took up the chase as Kit Carson dropped behind.

[CHAPTER XXII—A WHITE MAN IN THE INDIAN VILLAGE]

As Reuben dashed forward he speedily discovered that swift as was the pony he was riding it was unable to overtake the wild leader he was following. Indeed, in a brief time it became plain to the young trapper that his own horse was steadily dropping behind.

Aware, however, of the plan which was in the mind of Kit Carson for chasing the horse they were all so desirous of securing, he sturdily continued his efforts, all the time urging his horse to still greater endeavours. It seemed to Reuben that never before had he ridden so swiftly. The air appeared to strike him in the face, the hoofs of his flying animal barely touching the sand. And yet every time he glanced ahead he saw the black horse running easily, his neck arched and his head held high, the long tail sweeping the ground at every leap.

What a magnificent animal the leader of the drove was! And how easily he maintained his lead! Frequently the horse stopped and seemed almost to be tempted to turn and dash past its pursuer and rejoin his companions that had started toward a valley several miles distant.

And the hopeless part of his task was, as Reuben soon discovered, that the animal he was following did not seem to be tiring. It still ran easily when two miles or more had been covered by the pony which Reuben was riding. Jack could not be far away now, Reuben thought, and he began to peer anxiously ahead of him for the coming of his ally.

For some strange reason the black leader did not turn toward the plains. He was running nearer the hills than was Reuben’s mount, holding to his course, doubtless from the very fact that his pursuer was coming from the same direction.
