One strange report respecting the inhabitants of intra-tropical Africa, I think I shall be able to show the origin and foundation of, and which is the existence, in a situation to the south of Kuffah, of a nation of dwarfs, called Doko. From the information I have received myself, and from an examination of unpublished Portuguese documents relative to the geography of the eastern coast of Africa, and of the people inland; in the very situation presumed to be the native country of the Doko, I learn that a very different family of man is only to be found--the tall, muscular, and powerful Shankalli negro; and, more than this, the French traveller, M. d’Abbadie, from information received in Abyssinia, has reported that to the south of Enarea and Kuffah, a nation of Shankalli reside, to whom the name Doko was given. It cannot, therefore, I think, be doubted that a people so designated do occupy the country to the south of Abyssinia, and that from among them are taken the greater number of slaves, that arrive at the markets of Enarea and Zingero, where the dealers dispose of them to the slave Kafilahs that are proceeding to Zanzibar, or to northern Abyssinia. Doko perhaps designates the slave country, or, perhaps, signifies as much as our _terra incognita_, for we find the same word entering into the name of the unknown countries situated to the south of Bornou and the Mandara range, and, therefore, the Dukalata of those portions on the west of Africa may correspond with the equally unknown country of the Doko upon the eastern side.
