Adamawa, a country of vague extent in Central Africa, lying half way between Lake Chad and the Bight of Biafra, and watered by two tributaries of the Niger - viz. the Benuwe and the Faro. The soil is very rich, and there is abundance of durra, yams, ground-nuts, bananas, and cotton. Elephants are plentiful, and ivory forms an important export. Yolla, the capital, stands between the two rivers. Slavery prevails, and the government is in Mohammedan hands, the Sultan of Sokoto being the nominal suzerain.
