Of the Gemsbok, Captain Harris tells us that it “is about the size of an Ass, and nearly of the same ground colour, with a black list stripe down the back and on each flank, white legs variegated with black bands, and a white face, marked with the figure of a black nose-band and head-stall, imparting altogether to the animal the appearance of being clad in half-mourning. Its copious black tail literally sweeps the ground; a mane reversed, and a tuft of flowing black hair on the breast, with a pair of straight, slender horns (common to both sexes) three feet in length, and ringed at the base, completing the portrait.” The resemblance between the Gemsbok, when seen from the side view, and the Unicorn of heraldry, is sufficiently striking to make it more than probable that the conception of the latter originated in the former. The author just quoted says of the Blaubok, or Roan Antelope, by which name it is also known, that it “is an inhabitant of the elevated downs and ridges about the source of the river Limpopo [four degrees to the west of Delagoa Bay, and a little north of it], and being utterly destitute of speed, may be ridden to a standstill without difficulty.... It is heavily built, and has an upright mane, long asinine ears, and robust scimitar-shaped horns.” CHAPTER III.
