Reuben, who had followed directions and was making for the rear of the herd, now lost sight of his companion. He had a momentary glimpse of Jean when he was about thirty yards from the border of the herd, dashing into its midst. He heard the loud shout of the Frenchman, “A beau jeu beau retour!” but as he did not understand any of the words he was ignorant of Jean’s purpose. He saw the mass give way, and a half-dozen or more of the bulls, that were less fleet than the cows, turned to face the approaching hunter. Several of them, however, were thrown to the earth by the mass of maddened animals and rolled over and over upon the ground, hardly to be distinguished from the clouds of dust that now were settling all about them. Aware that Jean’s plan was, if possible, to separate one animal and pursue it until he had approached its side and then aim directly at its heart, Reuben became so interested that for a brief time he almost forgot the task which had been assigned him. Recalled in a few moments, however, and aware that Jean no longer was to be seen, he shouted to his horse to increase its speed and soon was swiftly moving toward the rear. He saw one cow slightly separated from the mass, and in a moment he was pursuing her as swiftly as the wolves had followed the buffalo calf a little while before. Steadily the young trapper gained upon his victim until at last his horse was alongside the animal he was seeking. Partly rising in his stirrups Reuben, when only a yard separated him from the buffalo, fired. The animal fell headlong at the discharge of the rifle, and then Reuben checked his horse and looked about him for his companion. Not far away he discovered Jean tying his horse to the head of a cow, which he was preparing to cut up. Filled with the spirit of the chase, Reuben decided that he would try to secure another cow. As he swiftly advanced he heard a shout from Jean, “Le coût en ôte le goût!” Still he did not understand what was said, and in his determination to secure another victim he did not heed the call, and soon was engaged in the mad pursuit of the flying herd. Whether or not it was due to the weariness of the horse he was riding, or to the increased speed of the buffaloes, Reuben never knew, but at all events he was compelled to continue the pursuit for a long distance. Unaware of the passing time and unmindful of the fact that the sun now was disappearing below the western horizon, intent solely upon securing another buffalo, Reuben still followed in the chase. A thick cloud of dust filled his mouth and eyes and at times nearly smothered him. There were moments, too, when the herd was not to be seen, so concealed was it by the cloud which the hundreds of feet had stirred up in the desert.
