Upon reaching the pool, which was about a hundred and thirty yards in diameter, we were immediately greeted by the hippo, who snorted and roared as we approached, but quickly dived, and the buoyant float ran along the surface, directing his course in the same manner as the cork of a trimmer with a pike upon the hook.
Several times he appeared, but, as he invariably faced us, Icould not obtain a favourable shot; I therefore sent the old hunter round the pool, and he, swimming the river, advanced to the opposite side, and attracted the attention of the hippo who immediately turned towards him. This afforded me a good chance, and I fired a steady shot behind the ear, at about seventy yards, with a single-barrelled rifle. As usual with hippopotami, whether dead or alive, he disappeared beneath the water at the shot. The crack of the ball and the absence of any splash from the bullet told me that he was hit; the ambatch float remained perfectly stationary upon the surface. I watched it for some minutes--it never moved; several heads of hippopotami appeared and vanished in different directions, but the float was still; it marked the spot where the grand old bull lay dead beneath.
I shot another hippo, that I thought must be likewise dead; and, taking the time by my watch, I retired to the shade of a tree with Hassan, while Hadji Ali and the old hunter returned to camp for assistance in men and knives, &c.
In a little more than an hour and a half, two objects like the backs of turtles appeared above the surface: these were the flanks of the two hippos. A short time afterwards the men arrived, and, regardless of crocodiles, they swam towards the bodies. One was towed directly to the shore by the rope attached to the harpoon, the other was secured by a long line, and dragged to the bank of clean pebbles.
I measured the bull that was harpooned; it was fourteen feet two inches from the upper lip to the extremity of the tail; the head was three feet one inch from the front of the ear to the edge of the lip in a straight line. The harpoon was sticking in the nape of the neck, having penetrated about two and a half inches beneath the hide; this is about an inch and three-quarters thick upon the back of the neck of a bull hippopotamus. It was a magnificent specimen, with the largest tusks I have ever seen;the skull is now in my hall in England.
Although the hippopotamus is generally harmless, the solitary old bulls are sometimes extremely vicious, especially when in the water. I have frequently known them charge a boat, and I have myself narrowly escaped being upset in a canoe by the attack of one of these creatures, without the slightest provocation. The females are extremely shy and harmless, and they are most affectionate mothers: the only instances that I have known of the female attacking a man, have been those in which her calf had been stolen. To the Arabs they are extremely valuable, yielding, in addition to a large quantity of excellent flesh, about two hundred pounds of fat, and a hide that will produce about two hundred coorbatches, or camel whips. I have never shot these useful creatures to waste; every morsel of the flesh has been stored either by the natives or for our own use; and whenever we have had a good supply of antelope or giraffe meat, I have avoided firing a shot at the hippo. Elephant flesh is exceedingly strong and disagreeable, partaking highly of the peculiar smell of the animal. We had now a good supply of meat from the two hippopotami, which delighted our people. The old Abou Do claimed the bull that he had harpooned as his own private property, and he took the greatest pains in dividing the hide longitudinally, in strips of the width of three fingers, which he cut with great dexterity.
Although the hippopotamus is amphibious, he requires a large and constant supply of air; the lungs are of enormous size, and he invariably inflates them before diving. From five to eight minutes is the time that he usually remains under water; he then comes to the surface, and expends the air within his lungs by blowing; he again refills the lungs almost instantaneously, and if frightened, he sinks immediately. In places where they have become extremely shy from being hunted, or fired at, they seldom expose the head above the surface, but merely protrude the nose to breathe through the nostrils; it is then impossible to shoot them. Their food consists of aquatic plants, and grasses of many descriptions. Not only do they visit the margin of the river, but they wander at night to great distances from the water if attracted by good pasturage, and, although clumsy and ungainly in appearance, they clamber up steep banks and precipitous ravines with astonishing power and ease. In places where they are perfectly undisturbed, they not only enjoy themselves in the sunshine by basking half asleep upon the surface of the water, but they lie upon the shore beneath the shady trees, upon the river's bank; I have seen them, when disturbed by our sudden arrival during the march, take a leap from a bank about twenty feet perpendicular depth into the water below, with a splash that has created waves in the quiet pool, as though a paddle-steamer had passed by. The Arabs attach no value to the tusks; these are far more valuable than elephant ivory, and are used by dentists in Europe for the manufacture of false teeth, for which they are admirably adapted, as they do not change colour. Not wishing to destroy the remaining hippopotami that were still within the pool, I left my men and old Abou Do busily engaged in arranging the meat, and I walked quietly homeward.
