Shortly after this I found myself on the banks of the stream, beside which my wagons were outspanned. Following along its margin, I presently beheld a bull of the borele, or black rhinoceros, standing within a hundred yards of me. Dismounting from my horse, I secured him to a tree, and then stalked within twenty yards of the huge beast under cover of a large strong bush. Borele, hearing me advance, came on to see what it was, and suddenly protruded his horny nose within a few yards of me. Knowing well that a front shot would not prove deadly, I sprang to my feet and ran behind the bush. Upon this the villain charged, blowing loudly, and chased me round the bush. Had his activity been equal to his ugliness, my wanderings would have terminated here, but by my superior agility I had the advantage in the turn. After standing a short time eyeing me through the bush, he got a whiff of my wind, which at once alarmed him. Uttering a blowing noise, and erecting his insignificant yet saucy-looking tail, he wheeled about, leaving me master of the field, when I sent a bullet through his ribs to teach him manners. Of the rhinoceros there are four varieties in South Africa, distinguished by the Bechuanas by the names of the borele or black rhinoceros, the keitloa or two-horned rhinoceros, the muchocho or common white rhinoceros, and the kobaoba or long-horned white rhinoceros. Both varieties of the black rhinoceros are extremely fierce and dangerous, and rush headlong and unprovoked at any object which attracts their attention. They never attain much fat, and their flesh is tough, and not much esteemed by the Bechuanas. Their food consists almost entirely of the thorny branches of the wait-a-bit thorns.
