Antelopes are exclusively inhabitants of the Old World; and some idea may be formed of their immense numbers in South Africa, where the species are most varied and powerful, by reading the following quotations from Mr. Pringle, and Mr. Gordon Cumming. The former says--"We pursued our journey over extensive plains, still parched by severe drought, and undulating heights clothed with a brown and scanty herbage, and sprinkled over with numerous herds of springbok. Near the banks of the Little Fish river, so numerous were those herds, that they literally speckled the face of the country, as far as the eye could reach; insomuch that we calculated we had sometimes within view not less than 20,000 of these beautiful animals. As we galloped on, they bounded off continually, on either side, with the velocity from which they derive their colonial appellation. They were probably _part_ of one of the great migratory swarms which, after long-continued droughts, sometimes inundate the colony from the Northern wastes." Mr. Cumming informs us, that, "When pursued, the springbok jumps up into the air ten or twelve feet, for which they curve their loins, rise perpendicularly, and the long white hair on their haunches and back floats about; they pass over a space of twelve to fifteen feet, come down, then rise again; and after doing this several times, they bound off, arch their necks, then halt, and face their enemy. If they come to a place over which men or lions have walked, they jump across it. They can only be compared to locusts; for they eat up every green thing, and always return to their haunts by a different road to that which they had previously passed. Their herds consist of tens of thousands; and where they have staid for some time, thousands of skulls strew the plain." In another part of his book, the same author tells us, that the ground was literally covered with them, forming a dense, living mass, marching slowly, and pouring like a great river for hours: hundreds of thousands scarcely tell their number. "I give you my word," said a boer, "that I have ridden a long day's journey, over a succession of flats covered with them as far as I could see, as thick as sheep standing in a fold." Among the Antelopes of the same part of the world is the Oryx, or Gemsbok, a very beautiful animal, which has been supposed to give rise to the Unicorn of Sacred writings; "for its long, straight horns, always so exactly cover one another, when viewing them from a distance, that they look like one. They have an erect mane, a long tail, and are like a horse, with the head and hoof of an Antelope. Their bearing is most noble, they are the size of an ass, have black bands about the head, looking like a stall collar. They live in almost barren regions, never want water, are very swift, and only to be caught by riding down."
