“The rutting-season over, the Orongos again live peaceably with one another, the males and females often collecting in separate herds. We saw a troop of about 300 does in February in the valley of the Shuga; the young are dropped in July. The Orongo is fearless and will let the hunter openly approach within 300 yards, or even nearer. The report of firearms or the whistle of a bullet does not alarm it; it only shows surprise by walking quietly away, frequently stopping to look at the hunter. Like other antelopes it is extremely tenacious of life and will run a long way although wounded. They are not difficult to shoot, for besides showing no fear, they haunt rocky defiles in the mountains, where they may be easily stalked. I have fired as many as from one to two hundred shots at them in the course of the day, my bag, of course, varying a good deal with my luck in the long shots. The Orongo is held sacred by the Mongols and Tangutans, and lamas will not touch the meat, which, by the way, is excellent, particularly in autumn when the animal is fat. The blood is said to possess medicinal virtues, and the horns are used in charlatanism: Mongols tell fortunes and predict future events by the rings on these, and they also serve to mark out the burial-places, or more commonly the circles within which the bodies of deceased lamas are exposed; these horns are carried away in large numbers by pilgrims returning from Tibet, and are sold at high prices. Mongols tell you that a whip-handle made from one will in the hands of the rider prevent his steed from tiring.”

It is almost unnecessary to say that living specimens of the Chiru have never, as yet, been brought to Europe.

The British Museum contains a mounted specimen of an adult male of the Chiru, obtained by Mr. Mandelli in Sikim and presented by Dr. W. T. Blanford; also some specimens presented by Hodgson, and a number of very fine skulls and horns from Ladakh and Kumaon from the Hume Collection.

Our illustration (Plate L.), which represents a male of this animal in a snowstorm, has been put upon the stone by Mr. Smit from a coloured drawing prepared by Mr. Wolf under the directions of the late Sir Victor Brooke.
