The Nile tributaries of Abyssinia and the Sword Hunters of the Hamran Arabs

This being a concise summary of the Nile system, I shall describe twelve months' exploration, during which I examined every individual river that is tributary to the Nile from Abyssinia, including the Atbara, Settite, Royan, Salaam, Angrab, Rahad, Dinder, and the Blue Nile. The interest attached to these portions of Africa differs entirely from that of the White Nile regions, as the whole of Upper Egypt and Abyssinia is capable of development, and is inhabited by races either Mohammedan or Christian; while Central Africa is peopled by a hopeless race of savages, for whom there is no prospect of civilization.
