rough.

They wished to leave Gondokoro as soon as possible, en route for
England, but delayed their departure until the moon should be in a
position for an observation for determining the longitude. 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. He foresaw that stay-at-home geographers,
who, with a comfortable arm-chair 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 gone through the country.
Accordingly they procured their information most carefully, completed
their map, and laid down the reported lake in
