Reuben whistled, but made no further response. Two minutes elapsed without any change in the direction in which the buffaloes were going. Then Jean said quickly, “I shall go to one side. It ees good for you to wait. When you shoot you must hit a cow, that ees the only meat that one can eat. Il trouverait à tondre sur un oeuf.” Whenever Jean fell into the use of his native language Reuben was aware that his excitement was almost beyond control. What the words meant he had no conception, but an instant later he saw Jean dashing directly toward the approaching herd. His horse now apparently was as excited as its rider. The weariness of the long journey of the day was forgotten or ignored. Without any definite plan, Reuben departed from the camp, moving in accordance with Jean’s advice toward the rear of the animals. The great mass was now less than a half-mile distant, and as the two hunters separated and approached the herd, Reuben saw that they had come within three hundred yards before the presence of the two riders was discovered. Then there was a sudden agitation in the huge body. The band apparently wavered for a moment, and some of the bulls galloped to and fro along the borders of the herd, betraying the fact that the presence of enemies had been discovered. The progress of the trappers, however, was not stayed. Riding steadily forward, they drew nearer the buffaloes. To Reuben the interest of the chase had now become so intense that all other things were ignored. Suddenly the movements of the dense mass were changed. The body swerved in a semicircle and apparently was in swift flight for the foothills. Within a few seconds the entire herd had joined in the flight, a guard of bulls as usual bringing up the rear. Frequently some of them stopped, and faced about as if they intended to test the strength or learn the purpose of the men on horseback. In every case, however, the huge animals speedily turned and once more dashed after the band, only to stop again and gaze at the horsemen. Indeed, as the minutes passed, Reuben was persuaded that the animals were minded to stand and fight. Whatever may have been the impulse, however, as the hunters increased the pace at which they were riding the confusion in the herd became more manifest. The buffaloes were moving over the ground now with increasing swiftness, while the rumbling and roaring became steadily louder as the speed increased.
