My boats were fortunately engaged by me for five months, thus Speke and Grant could take charge of them to Khartoum.
At the first blush on meeting them, I had considered my expedition as terminated by having met them, and by their having accomplished the discovery of the Nile source; but upon my congratulating them with all my heart upon the honor they had so nobly earned, Speke and Grant with characteristic candor and generosity gave me a map of their route, showing that they had been unable to complete the actual exploration of the Nile, and that a most important portion still remained to be determined.

It appeared that in N.lat.2 "degrees" 17', they had crossed the Nile, which they had tracked from the Victoria Lake; but the river, which from its exit from that lake had a northern course, turned suddenly to the WEST from Karuma Falls (the point at which they crossed it at lat.

2 "degrees" 17').

They did not see the Nile again until they arrived in N.lat.3 "degrees" 32', which was then flowing from the west-south-west.

The natives and the King of Unyoro (Kamrasi) had assured them that the Nile from the Victoria N'yanza, which they had crossed at Karuma, flowed westward for several days' journey, and at length fell into a large lake called the Luta N'zige; that this lake came from the south, and that the Nile on entering the northern extremity almost immediately made its exit, and as a navigable river continued its course to the north, through the Koshi and Madi countries.
Both Speke and Grant attached great importance to this lake Luta N'zige, and the former was much annoyed that it had been impossible for them to carry out the exploration.
