"It is very hungry," said David. "We will try if it will take some milk." While Leo and Natty ran off to milk a goat, the men held the little animal, which, though it trembled, made no attempt to escape. David examined the head of the larger one. It had beautiful horns, nearly three feet in length, slightly curving backwards, and of a shiny black colour, and very slender. The mane and tail were very like those of a horse, while the shape of the head and the colour were those of an ass, the legs and feet, however, showing it to be an antelope. Both the horns were so exactly equal that I could fancy a person taking a side view of the animal might imagine them to be one and the same; and David said that the gemsbok has often therefore been supposed, by those who have seen it at a distance only, to be the unicorn which the ancients believed to exist. The little calf was of a reddish cream colour, and was so small that the horns had scarcely yet appeared. Timbo told us that the gemsboks were generally seen in small herds. Probably this one and its calf had been separated from their companions, as no others had been taken. It is one of the swiftest quadrupeds of Africa, indeed its speed is almost equal to that of the horse. Herds of them are generally found in districts devoid of water, as they can go a long time without drinking, having receptacles in their inside somewhat like those of a camel, though much smaller, for retaining fluid. As soon as the milk was brought David tried to feed the little creature with a spoon instead of the bottle, and after a few attempts it willingly swallowed the milk. He then applied the bottle to its mouth, and as soon as it found out its contents it sucked it eagerly; he had hopes, therefore, of being able to bring it up. Kate and Bella, summoned by the boys, now came in to inspect their new pet. It allowed Bella to stroke it and pet it without evincing any fear, and when she fastened a handkerchief round its neck it followed her willingly. "What a dear little creature!" she exclaimed. "We must give it a name, though. I do not think gemsbok is pretty. I like oryx better." "I am afraid, however, when he gets his horns he will prove rather a dangerous companion," observed David, looking at the head of the larger animal which lay on the ground outside the hut. "It will fearlessly encounter the most savage animals of the desert, and instances have occurred where it has succeeded in killing even a lion or tiger which had incautiously sprung on its dagger-like weapon of defence." "Oh, it will be a long time before those grow!" said Leo. "We can pad them, or cut off their tips, and then it can hurt no one, even in play." Stanley and the two black boys were out hunting, and in the evening they appeared, the boys carrying slung on two poles an animal which we saw at once was alive.
