What the gemsbok feeds upon is rather a mystery, for it is often found in districts where there is no vegetation except a little dry scrub. Yet it nearly always seems to be in good condition. And it is odder still to find that for months together sometimes it must go without drinking! Some hunters, indeed, have declared that they are quite positive that the animal never drinks at all, obtaining all the moisture it needs from small watermelons and certain bulbous roots. The gemsbok is of about the same size as the kudu, and is gray in color above and white below. But there is a black streak across the face, while another streak, which is much broader, runs along the sides, dividing the gray of the upper parts from the white of the lower. This antelope is hunted on horseback, and is so swift and so enduring, that there is said to be no animal in Africa which is harder to overtake. THE SPRINGBOK The most graceful and elegant of all the antelopes are the gazelles, of which we may take the springbok as an example. In former days this was by far the most abundant of all the African game animals, and would sometimes be seen traveling from one district to another in enormous herds, covering the country as far as the eye could reach. So vast were these herds, indeed, and so closely did the animals march side by side together that sometimes a lion would be seen in their ranks marching along with them, quite unable to stop, or to make his escape, because of the pressure all round him! The springbok, or "springbuck," owes its name to its marvelous activity, and to its curious habit of suddenly leaping straight up into the air. In this way it can easily spring to a height of eight or ten feet. The springbok is easily tamed, and soon comes to know who are its friends. One of these animals was kept as a pet by a lady living at Klerksdorp, in South Africa, and would wander about the town by itself, not seeming to be in the least afraid of the passers-by, or even of the dogs. Every morning, too, it would cross the river, and go out upon the veldt to feed; and although it would mix freely with its wild companions during the day, it always left them in the evening and came home to sleep. In height the springbok stands about two feet six inches, and it can easily be distinguished from all the other gazelles by the white streak which runs along the middle of the back. The horns are black, with a number of ridge-like rings running round them, and the color of the coat is dark cinnamon-yellow above and white beneath, with a blackish stripe on the flanks between the two.
