Dr. Schweinfurth's discovery of the Welle river flowing towards the west, between the 3rd and 4th deg. N. lat., is a clear proof that no river can be running from the south to the north-east towards the Nile Basin, otherwise the Welle river would be intersected.
In page 186, vol. ii., Dr. Schweinfurth [*] writes:—"Its course [the Lualaba], indeed, was towards the north; but Livingstone was manifestly in error when he took it for a true source of the Nile, a supposition that might have some semblance of foundation originating in the inexplicable volume of the water of Lake M'wootan (Albert N'yanza), but which was negatived completely as soon as more ample investigation had been made as to the comparative level, direction, and connection of other rivers, especially of the Welle."
[*Footnote: "The Heart of Africa.">[
Although Dr. Schweinfurth was unprovided with astronomical instruments, we may place thorough reliance in the integrity and ability of this traveller, who has taken the greatest pains to arrive at true conclusions. I am quite of his opinion, that the Welle is outside the Nile Basin, and drains the western watershed.
In a letter from Dr. Livingstone addressed to Sir Bartle Frere, dated Lake Bangweolo, 27th Nov. 1870, he writes:—" The Tanganyika, whose majestic flow I marked by miles and miles of confervae and other aquatic vegetation for three months during my illness at Ujiji, is, with the lower Tanganyika, discovered by Baker, a riverine lake from twenty to thirty miles broad."
It is thus clear that Livingstone considered that the Tanganyika and the Albert N'yanza were one water. On 30th May, 1869, dated Ujiji, he writes to Dr. Kirk:—"Tanganyika, N'zige Chowambe (Baker?) are one water, and the head of it is 300 miles south of this."
"The majestic flow" of confervae remarked by Livingstone on the Tanganyika is beyond my comprehension, if that vast lake has no outlet at the north.
In Livingstone's letter of 27th Nov., 1870, he writes:—"Speke's great mistake was the pursuit of a foregone conclusion. When he discovered the Victoria N'yanza he at once leaped to the conclusion that therein lay the sources; but subsequently, as soon as he and Grant looked to the N'yanza, they turned their backs on the Nile fountains. Had they doubted the correctness of the conclusion, they would have come west into the trough of the great valley, and found there mighty streams, not eighty or ninety yards, as their White Nile, but from 4,000 to 8,000 yards, and always deep."
I was surprised that Livingstone could make such an error in quoting Speke's White Nile from the Victoria N'yanza as eighty or ninety yards in width! At M'rooli, in latitude N. 1 degree 37", I have seen that magnificent river, which is at least A THOUSAND YARDS in width, with a great depth. I have travelled on the river in canoes, and in the narrowest places, where the current is naturally increased; the width is at least 300 yards.
From my personal experience I must strenuously uphold the Victoria Nile as a source of enormous volume, and should it ever be proved that the distant affluents of the M'wootan N'zige are the most remote, and therefore the nominal sources of the Nile, the great Victoria N'yanza must ever be connected with the names of Speke and Grant as one of the majestic parents of the Nile Basin.
