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. He foresaw that stay-at-home geographers, who, with a
comfortable armchair to sit in, travel so easily with their fingers on a
map, would ask him why he had not gone from such a place to such a
place? why he had not followed the Nile to the Luta N'zige lake, and
from the lake to Gondokoro? As it happened, it was impossible for Speke
and Grant to follow the Nile from Karuma:--the tribes were fighting
with Kamrasi, and no strangers could have got through the country.
Accordingly they procured their information most carefully, completed
their map, and laid down the reported lake in its supposed position,
showing the Nile as both influent and effluent precisely as had been
explained by the natives.

Speke expressed his conviction that the Luta N'zige must be a second
source of the Nile, and that geographers would be dissatisfied that he
had not explored it. To me this was most gratifying. I had been much
disheartened at the idea that the great work was accomplished, and that
nothing remained for exploration; I even said to Speke, "Does not one
leaf of the laurel remain for me?" I now heard that the field was not
only open, but that an additional interest was given to the exploration
by the proof that the Nile flowed out of one great lake, the Victoria,
but that it evidently must derive an additional supply from an unknown
lake as it entered it at the NORTHERN extremity, while the body of the
lake came from the south. The fact of a great body of water such as the
Luta N'zige extending in a direct line from south to north, while the
general system of drainage of the Nile was from the same direction,
showed most conclusively, that the Luta N'zige, if it existed in the
form assumed, must have an important position in the basin of the Nile.
