In the Brazil the richest lands are given to coffee, the next best to sugar, and the worst to cotton and cereals. The Zanzibar coast from Mombasah to Mozambique produces small quantities of coffee. Here great care is given to it; the berry has a peculiarly dry and bitter flavour, pleasant when familiar, and producing when first taken wakefulness and nervous excitement. At present the Island imports her supplies from Malabar and Yemen. The consumption is not great; the Arabs, who hold it a necessary of life at home, here find it bilious, and end by changing it for betel-nut. The coast growth sells in small lots, at various prices, and may become an article of export. In the African interior the shrub is indigenous between Northern Unyamwezi (S. Lat. 1° 0′) and Southern Abyssinia (N. Lat. 10°); and, as it is found on the Western Coast growing wild about the Rivers Nunez and Pongo (N. Lat. 10° 1′), it probably extends in a broken band across the Continent. There appear to be many varieties of the shrub. In Karagwah the wild bean is little bigger than a pin’s head. Harar exports a peculiarly large species, which sells as Mocha, and the Mozambique coffee does not at all resemble in flavour that of West Africa. Dr Livingstone (Missionary Travels, chap. x.) tells us that coffee brought from Southern Arabia to Angola by the Jesuits was spread probably by agency of birds to 300 leagues from the coast. It has long been ‘monkeys’ food,’ but it is now worked by the ex-slavers. Indigo here, as well as in most parts of intertropical Africa, grows wild. The great expense of establishments, with the time and trouble, the skill and attention required for the manufacture, will leave it in the hands of Nature for many years to come. Tobacco might be raised: the plant extends thoughout Eastern and Central Africa, wherever the equinoctial rains fall. Usumbara exports to Zanzibar stiff, thin, round cakes which have been pounded in wooden mortars, and neatly packed in plantain leaves. It is dark and well- flavoured: sailors pronounce it to be very ‘chawable.’ Here it sells at two pice,[56] or 3/4_d._, per cake; at Usumbara it commands about one- fifth of that price, paid in cloth and food. The oil palm (Elæis Guineensis), whose produce has done so much for the Guinea Coast and the fatal Bight of Biafra, is found, I am told, on the Island of Pemba, and at other places near Zanzibar. About the Lake Tanganyika it grows in abundance; the fruit, however, is a raceme, like the date’s, not a spike, as in the Bonny river. The ‘Mchikichi’ is, therefore, a different and probably an unknown species. Like that of West Africa, it supplies wine as well as oil (The Lake Regions of Central Africa, vol. ii. p. 59). The palm-oil might easily be introduced into Zanzibar, and would doubtless thrive; but the people have enough to do without it.
