The lower canine teeth or tusks of the hippopotamus grow to a great size, and in bulls may weigh from 4 lbs. to 7 lbs. each. They are curved in shape, and when extracted from the jaw form a complete half-circle, and have been known to measure upwards of 30 inches over the curve. In life, however, not more than a third of their length protrudes beyond the gums.
During the daytime hippopotamuses are seldom met with out of the water. They lie and doze all day long in the deep pools of the rivers they frequent, with only their eyes, ears, and nostrils above the surface, or else bask in the sun on the tail of a sandbank, looking like so many gigantic pigs with their bodies only partially submerged. Sometimes they will lie and sleep entirely out of water amongst reeds. I have seen them feeding in the reed-beds of the great swamps of the Chobi just at sundown, but as a rule, they do not leave the water until after dark. At night they often wander far afield, especially in the rainy season, in search of suitable food; and after having been fired at and frightened, I have known a herd of hippopotamuses to travel at least five-and-twenty miles along the course of a river during the ensuing night, in order to reach a larger and deeper pool than the one in which they had been molested.

HIPPOPOTAMUSES BATHING.
A hippopotamus stays under water for about 2½ minutes at a time, and then just shows part of its head above water while it draws a fresh breath.
Although the hippopotamus is thoroughly at home in the hottest parts of Africa, and appears to thrive in the tepid waters of all the rivers which flow through the malarious coast regions of the tropical portions of that continent, it is also found at a considerable altitude above the sea, and in quite small streams where the temperature of the water during the winter months cannot be many degrees above freezing-point. I have personally met with hippopotamuses in the Manyami River, not far from the present town of Salisbury, in Mashonaland. The country there has an altitude of about 5,000 feet above sea-level; and the water was so cold on the last occasion on which I came across the animals in question—July, 1887—that, if a basinful was left out during the night, ice quite an eighth of an inch in thickness would be formed over it before morning. There was, however, never any ice on the river itself. During the rainy season, when the grass and reeds are green and succulent, hippopotamuses become enormously fat, especially in the higher and colder portions of their range, and retain a good deal of their fat right through the driest season of the year. Old bulls are usually very lean; but I have seen cows the greater part of whose carcases, after the skin had been stripped off, was covered with a layer of fat from 1 inch to 2 inches in thickness. The meat of these animals is dark red in colour, and more like beef than pork. To my mind, that of a young animal is most excellent in flavour, and far preferable to that of a lean antelope. The fat, when prepared, is as good as the best lard, from which, indeed, it is hardly distinguishable. The skin of the hippopotamus is smooth and hairless, and in adult animals quite 1½ inch in thickness on the upper parts of the body.
