Lovett Cameron, started from Zanzibar; but in October, 1873, while at Unyanyembé, its leader received the intelligence of Livingstone’s death, which had taken place at Ujiji, and soon afterwards the corpse arrived in charge of his faithful followers. Cameron then took up the work of exploration, and in spite of immense difficulties, great mental and physical suffering, and obstacles of every kind, he made his way to Lake Tanganyika, thence to Nyangwé, and after identifying the Lualaba with the Kongo, struck to the southward, and passing through regions hitherto unexplored, struck the west coast at Benguela. As a result of his observations, Lieutenant Cameron thus sketches the river system of Africa:— “The basin of the Nile is probably bounded on the south-west by the watershed reached by Dr. Schweinfurth; on the south of the Albert Nyanza, by the high lands between that lake and the Tanganyika, whence the watershed pursues a tortuous course to Unyanyembé (where, I believe, the basins of the Nile, Kongo, and Lufiji approach each other), and then follows a wave of high land running east till it turns up northwards along the landward slopes of the mountains dividing the littoral from the interior. Passing by Mounts Kilima Njaro and Kenia, it extends to the mountains of Abyssinia, where the sources of the Blue Nile were discovered by Bruce [1770], and so on to the parched plains bordering the Red Sea, where no rains ever fall. The western boundary of the Nile basin is, of course, the eastern portion of the desert. “The basins of the Niger and the Ogowai cannot yet be defined with any degree of exactitude, and the northern boundary of the basin of the Kongo has still to be traced. “The Zambési drains that portion of the continent south of the Kongo system, and north of the Kalahari desert and the Limpopo, the northern boundary of the Transvaal Republic; some of its affluents reaching to within two hundred and fifty miles of the west coast. “The mighty Kongo, king of all the African rivers, and second only to the Amazon (and perhaps to the Yang-tse-Kiang) in the volume of its waters, occupies a belt of the continent lying on both sides of the equator, but most probably the larger area belongs to the southern hemisphere. Many of its affluents fork into those of the Zambési on a level tableland, where the watershed is so tortuous that it is hard to trace it, and where, during the rainy season, floods extend right across between the head-waters of the two streams. “The Kelli, discovered by Dr. Schweinfurth, may possibly prove to be the Lowa, reported to me as a large affluent of the Lualaba [or Kongo] to the west of Nyangwé; or, if not an affluent of the Lualaba, it most probably flows either to the Ogowai or the Tchadda, an affluent of the Niger.”
