The manufacture of the pottery all falls to the care of the women, who do not shrink from the most difficult tasks, and, without the help of any turning-wheel, succeed in producing the most artistic specimens. The larger water-bottles are sometimes not less than a yard in diameter. The clay water-pots are ordinarily of a broad oval shape, adapted for being carried on the head with the narrow end resting on a kind of porter’s knot, which is made either of leaves or plaited straw. Handles are uniformly wanting: for, whatever may be the purpose to which the vessels are applied, whether for holding water or oil, for boiling or for baking, the material of which they are made contains so large a quantity of mica (which the natives do not understand how to get rid of), that it is very brittle, and the imperfect baking in the open air contributes to this brittleness. To compensate for the lack of handles by which the vessels might be lifted, their whole outer surface is made rather rough by being ornamented by a number of triangles and zigzag lines, which form all manner of concentric and spiral patterns. The gourd-platters and bottles are generally decorated with different dark rows of triangles. A large amount of labour is expended upon the manufacture of clay bowls for pipes, which are often really elaborate, and have generally quite a European character; very often their design consists of a human head, and these are so treasured as works of art, that their possessors cannot be induced to part with them at any price. The preparation of skins for leather aprons and similar purposes has hitherto been limited amongst the Bongo, as probably amongst all the heathen negroes, to the simplest mechanical process of kneading and fulling by means of ashes and dung, which is followed up by a liberal application of fat and oil till a sufficient degree of softness and pliancy is attained. Recently from the Nubians the use of tan has become generally known, and it may not unreasonably be conjectured that the method of using it will gradually extend from the north of Africa towards the south, in the same way as it has spread upwards from the Cape. Previous to their contact with Europeans, none of the southern people of Africa had discovered the use of tan, although the skins of their animals were a very important item in their economy. In Bongoland at present the bark of the Gere (_Hymenocardia Heudelotii_) is what is most frequently employed, and the red tan it yields is found to be very effectual.
