In speaking of the great quantity of food necessary to support this enormous mass, we must likewise consider the vast quantity of water which he needs. No country but that of the Shangalla, which he possesses, deluged with six months rains, and full of large and deep basons, made in the living rock, and shaded by dark woods from evaporation; or watered by large and deep rivers, which never fall low or to a state of dryness, can supply the vast draughts of this monstrous creature; but it is not for drinking alone that he frequents wet and marshy places; large, fierce, and strong as he is, he must submit to prepare to defend himself against the weakest of all adversaries. The great consumption he constantly makes of food and water necessarily confines him to certain limited spaces; for it is not every place that can maintain him, he cannot emigrate, or seek his defence among the sands of Atbara. The fly, that unremitting persecutor of every animal that lives in the black earth, does not spare the rhinoceros, nor is afraid of his fierceness. He attacks him in the same manner as he does the camel, and would as easily subdue him, but for a stratagem which he practises for his preservation. The time of the fly being the rainy season, the whole black earth, as I have already observed, turns into mire. In the night when the fly is at rest, he chooses a convenient place, and there rolling himself in the mud, he clothes himself with a kind of case, which defends him against his adversary the following day. The wrinkles and plaits of his skin serve to keep this muddy plaster firm upon him, all but about his hips, shoulders, and legs, where it cracks and falls off by motion, and leaves him exposed in those places to the attacks of the fly. The itching and pain which follow occasion him to rub himself in those parts against the roughest trees, and this is at least one cause of the pustules or tubercules which we see upon these places, both on the elephant and rhinoceros. The Count de Buffon, who believes these pustules to be natural parts of the creature, says, in proof of this, that they have been found in the fœtus of a rhinoceros. I do not pretend to disbelieve this; it may be, that these punctures happening to the old female at the time she was with young, the impression of her sufferings might have appeared upon the young one. However this is, I cannot conceal that I have heard, not from hunters only, but men worthy of credit, that this is the origin of these protuberances; and many rhinoceroses, slain in Abyssinia, are known to have been found at the season of the fly, with their shoulders and buttocks bloody and excoriated. It is likewise by no means true, that the skin of the rhinoceros is hard or impenetrable like a board. I should rather suspect this to be disease, or from a different habit acquired by keeping; for in his wild state he is slain by javelins thrown from indifferent hands, which I have seen buried three feet in his body.
