They frequent the cliffs and ledges of mountain rocks, the bush-tangled wastes on the tropical plains, and the margins of the arid wildernesses. There they bound, and spring, and career, fleet as the winds; now balancing themselves where one would hardly imagine there was foot-fall for a bird; now clearing the jungle as if they were winged creatures; and now bounding along the plain with the speed of the winds. To those who have been accustomed only to the motions of the more sober animals—to the heavy tread of the ox, or the pattering trot of the sheep, the antelopes present something truly novel. From some unseen hollow among the cliffs, one of these animals will bound upwards, and alight upon its feet on a pinnacle only a few inches in breadth. There it will stand in perfect security, with its feet all touching each other, and its back bent like a bow, surveying the cliffs around; and no sooner has it espied a new footing to its mind, than it bounds off again, though the distance be many fathoms.
