Although the American bison or buffalo has been virtually extinct for years, the animals were numbered by the hundred thousand on the western plains at the time we have in mind. The droves seen in the distance seemed often to cover a fourth of the horizon, and their dark, shaggy backs as they cropped the herbage and hitched continually forward, were like the fretted waves of the sea. Shagbark had shot a number, and twice he took Alden and Jethro with him on the excursions. A nearly fatal result to Alden followed the attempted slaying of an enormous bull by shooting him in the head instead of just behind the fore leg, but the mistake was not repeated. Jethro showed his natural timidity, and kept as close as he could to the veteran, while Alden indulged in spurts of his own which more than once brought results.

Shagbark, however, was not partial to buffalo meat, which many of his friends found coarse and tough. They preferred venison, which was not always tender, and they were able to obtain considerable quantities of it. He regarded the antelope with more favor than either. So it came about on the morning referred to, that he and the two youths set out to shoot some of the timid creatures. Occasionally Mr. Fleming and some of his friends took part in the hunts, but they preferred to stay in camp on this day and let the trio prove their prowess.

The effect of this halt was to increase the distance between the party and the one in advance, to which Garret Chadwick and his nephew belonged; for the latter company moved at an early hour and were many miles distant before nightfall.

Antelope hunting has been too often described for me to dwell upon this particular venture. When the three rode over the plains to the northwest in the direction of the towering Laramie Mountains, not one of the animals was in sight, nor had the guide seen any on the previous day. He had been over the region before, however, and knew he would not have to hunt long.

He first headed toward a ridge which rose two hundred feet or more above the prairie, showing few boulders and rocks, and no trees. Beyond it stretched a beautiful valley to the foothills of the mountain range. This space was several miles in width, and a small, clear stream meandered through the valley, on its way to the Sweetwater, and thence to the North Platte. Shagbark gave it as his belief that some of the animals would be found in the valley, and, as usual, he was not mistaken.

The American antelope or pronghorn is a native of the plains near the Rocky Mountains. Nearly always the upper parts of its body are yellowish brown in color, while the under parts, the sides and the head and throat and the buttocks are white. It sheds the bony sheath of its horns every year. It may be worth noting that this creature is known also by the names of prongbuck, pronghorned antelope, cabrèe and cabut.

The most peculiar trait of the antelope is its curiosity. But for this weakness, it would be almost impossible for a hunter to get within range of the game. Lying in the grass, where his body is invisible, the man lifts his hat or a handkerchief on the muzzle or ramrod of his rifle. The moment the animal sees it he bounds off in a panic, but does not go far before he halts and looks back. The odd sight has roused his curiosity, and he gingerly draws near, ready to dash away again in the instant danger shows himself.

All the hunter needs to have is patience. The creature is sure to come within reach of his gun and fall a victim to the infirmity that had proved the undoing of many a human being. It is hard to understand this singular failing of the antelope.

At the base of the ridge Shagbark drew rein and his companions did the same.
