There is likewise a vast quantity of sea and river fish: the spermaceti whale is sometimes found at Sierra Leone, but more frequently on the northern coasts. There are also sharks, thorn-backs, porpoises, eels, mackarel, and mullet, all of which are eaten, except the eels. Oysters and the other kinds of shell-fish are likewise very plentiful, and serve as food for the natives. Green turtle are very common here, and are often of an inconceivable size. Land and river tortoises are also to be met with; the former in great numbers: they are used by the people, and might be sent to Europe with advantage. Amongst the zoophites, none deserve greater attention than the common spunge, which covers the sandy shores, and with which a considerable trade might be carried on. The beasts of prey are lions, leopards, hyænas, civet cats, and several species of weazles. The last mentioned animals are great enemies of poultry. There are likewise apes of various species. The chimpanzee is common on the mountains of Sierra Leone, and resembles a man more than the ourang-outang: its greatest height is nearly five feet, and it is covered with long and thick hair down the back, but short and light on the breast and belly. Its face is without hair, and the hands and head are similar to those of an old Negro, except that the hair of the head is not curly. It eats, drinks, sleeps, and sits at table like a human being. When young, it walks on all fours; but treads on the back of its hands: when grown up, it moves erect by the aid of a stick. This animal is always gentle and good natured. A species of crocodiles and caymans is to be seen here, which has never been described by naturalists: they are ten or twelve feet long. There are six known species of lizards, amongst which are the guarra and the cameleon. Serpents are innumerable: they enter the houses during the night for the purpose of catching the poultry: the largest which was ever known here, was eighteen feet long; but it was found not to be venemous. Insects are innumerable in this part of the world. The most remarkable are the _termites_, or white ants, which eat and even destroy hedges and houses that are built of wood; while the common ants only devour provisions. The grasshoppers and crickets consume clothes, linen, and leather; and there are mosquitoes, flies, scorpions, and centipedes, as well as wild bees, the last of which furnish wax and honey in abundance. Worms are little known; but the barnacles are large, and do much injury to the ships that are not covered with copper.
