Not only is the inundation the effect of the Abyssinian rains, but the deposit of mud that has formed the Delta, and which is annually precipitated by the rising waters, is also due to the Abyssinian streams, more especially to the river Atbara, which, known as the Bahr el Aswat (Black River), carries a larger proportion of soil than any other tributary of the Nile; therefore, to the Atbara, above all other rivers, must the wealth and fertility of Egypt be attributed.

It may thus be stated: The equatorial lakes FEED Egypt; but the
Abyssinian rivers CAUSE THE INUNDATION.

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.

The exploration of the Nile tributaries of Abyssinia occupied the first twelve months of my journey towards the Nile sources. During this time, I had the opportunity of learning Arabic and of studying the character of the people; both necessary acquirements, which led to my ultimate success in reaching the "Albert N'yanza." As the readers of the work of that title are aware, I was accompanied throughout the entire journey by my wife, who, with extraordinary hardihood and devotion, shared every difficulty with which African travel is beset.
