The antelope has a number of marked characteristics and some of these are unique. It is without dew claws; the hair is hollow and filled with pitch; teeth are of peculiar pattern; it eats mostly bitter or pungent food; has large, long-range eyes of almost telescopic power; has numerous and scattered scent glands; is without colour camouflage--in fact, its colour is in part revealing, for the bristling of its white buttocks serves to give signal flashes. The antelope is the plains’ graceful racing model of long and successful development. It is either the least--the smallest--or near the smallest of our hoofed wild animals. The antelope is specialized in speed. If there were to be a free-for-all race on the plains, with deer, antelope, elk, sheep, bear, lion, coyote, fox, dog, horse, and even the rabbit as starters, the antelope generally would be the winner, whether the race was for one mile or ten. Perhaps the blooded race horse and the greyhound would outstrip him, but among wild animals the antelope is the speedy one. Wolves and coyotes pursue the pronghorn in relays or capture it strategically through various kinds of mutual aid. Now and then an antelope will turn upon its pursuers and fight them fiercely, occasionally triumphantly. On the Great Plains in western Nebraska I saw two speeding objects stirring dust on the horizon. It was an antelope cut off from the flock and pursued by a wolf. They plunged for a moment or two in a dip of the plains, then reappeared. With glasses on them I saw the pursuing wolf drop out and another wolf leap from concealment to relieve him. Following them through glasses as they raced on skyline against a cloud, dropped below eyeline, dashed behind a butte, swiftly the great circle followed brought them within half a mile. In plain view another wolf leaped into the race. The antelope was nearly exhausted. The wolves were leaping at her throat as she disappeared over a ridge. Little puffs of dust showed the advance of pursuer and pursued. These grew dim and I watched for the runners to come up on the skyline. But they never appeared. [Illustration: _Photo. by Enos A.

She paid no apparent attention to him. But she was besieged. After two or three hours he was relieved by another coyote. This was a new and rather leisurely way of relaying. Evidently the devilish plan was to wear the antelope out or stay until she was forced to go for water and then seize the youngsters.
