The length of the horn varies in the different species, the main horn of the kaboba exceeding four feet, while that of the moohooho is seldom over two feet. In all cases, among the double-horned animals, the rear one—that is to say, the one nearest the forehead—is always short, not often more than six inches.
There are many singular superstitions regarding the horn of the rhinoceros, which is not as valuable for its ivory as that from the elephant. Rhinoceros-horn shavings are supposed by many people to cure certain diseases, and it is believed that if poison be poured in a cup made of the horn, it will burst it. A German writer says: "This horn will not endure the touch of poison; I have often been a witness of this. Many people of fashion at the Cape have cups turned out of the rhinoceros horn; some have them set in silver, and some in gold. If wine is poured into one of these cups, it immediately rises and bubbles up as though it were boiling, and if there is poison in it, the cup immediately splits. If poison is put by itself into one of these cups, it in an instant flies to pieces.... The chips made in turning one of these cups are ever carefully saved and returned to the owner of the cup, being esteemed of great benefit in convulsions, faintings, and many other complaints."
As to whether the horn of the rhinoceros is such a test for poison, the reader may safely doubt; but it can make little difference, since it is hardly probable he cares either for the wine or the poison, and has no need of such a sensitive drinking cup.
Clumsy-looking as the great brute is, Mr. Gordon Cumming says "a horse and rider can rarely manage to overtake him." Another famous African hunter writes: "He is not often pursued on horseback, and chiefly because his speed and endurance are such that it is very difficult to come up with and follow him, to say nothing of the danger attendant on such a course. Many a hunter, indeed, has thereby endangered his life."
One of the most singular of attendants is that which the rhinoceros has. It is a little bird called by ornithologists Buphaga africana, and known to hunters as the rhinoceros bird. This little fellow clings to the animal's hide by means of its long claws and elastic tail, feeding on the insects that infest the leathery skin. In doing this it renders great service to the huge brute, but trifling as compared to its other duty. It acts as sentinel to warn its movable feeding-place of approaching danger. While it is eating it is ever on the alert, and at the first sign of the hunter it flies up in the air uttering its warning note, which is ever quickly heeded, the rhinoceros starting off at once in the direction taken by its watchful friend. Mr. Cumming states that when the rhinoceros is asleep, and the bird, hearing the approach of the hunter, fails to awaken him by its voice, it will arouse him by pecking the inside of his ear.
Some species of the rhinoceros are inclined to peace, and will rarely attack man save in defense of their young or their lives, while others, and more particularly the keitloa, will attack man or beast simply to gratify their love for fighting. The lion never risks an encounter with the rhinoceros, save when absolutely necessary for his own safety, and it is but seldom the elephant cares to measure strength with him, for the larger animal is far less quick in his movements than the smaller.
A celebrated African hunter once witnessed a battle between these huge animals; but in this instance the impetuous rage of the rhinoceros proved his downfall, for having driven his terrible horn up to the hilt into the carcass of the elephant, he was unable to extract it, and the latter falling, crushed the life out of his assailant in the descent. A traveller once saw a fight between a gigantic male elephant and a black rhinoceros, that was ended by the flight of the former.
FIGHT BETWEEN A KEITLOA AND A PANTHER.
It is seldom that such an encounter as that shown in the engraving takes place, for the very good reason that the panther, knowing its death is the almost certain result of the combat, slinks away before the keitloa. Only in defense of its young, as in the case shown, or when it fears an attack is to be made, does it oppose the rhinoceros, and then the sharp horn easily pierces the spotted skin, or the ferocious mother is crushed beneath the ponderous feet of her enemy.
