- "The Drainage Clearly Did Not Go Into Tanganyika, And That Lake, Though It Probably Has An Outlet, Lost All Its Interest To Me As A Source Of The River Of Egypt."

We are, therefore completely in the dark concerning the flow of water from the Lualaba south of the equator, and of Schweinfurth's Welle north of the equator, but both these large rivers were tending to the same direction, north-west.

The discovery of these two rivers in about the same meridian is a satisfactory proof of the western watershed, which completely excludes them from the Nile Basin. If the Tanganyika lake has no communication with the Albert N'yanza, the old Nile is the simple offspring of the two parents - the Victoria and the Albert lakes. (This is now proved to be the case.)

When the steamer that I left at Gondokoro in sections shall be launched upon the Albert N'yanza, this interesting question will be quickly solved.

Early in November, 1871, when I was on the Nile south of Regiaf, I noticed the peculiar change that suddenly took place in the river. We were then in N. lat. 4 degrees 38", below the last cataracts, where the water was perfectly clear and free from vegetation, with a stream of about three and a half or four miles per hour.

Suddenly the river became discoloured by an immense quantity of the Pistia Stratiotes, of which not one plant was entire.

This aquatic plant invariably grows in either dead water or in the most sluggish stream, and none existed in the part of the river at N. lat.
