Leaving Uganda in December, 1875, Stanley accompanied an expedition sent by Mutesa to the countries then governed by the Banyoro at the base of Ruwenzori. Amazing to relate, Stanley was actually encamped under the Ruwenzori range (called, by the Baganda, Gambaragara), and yet was unaware of the importance of his discovery. He guessed that the mountain in front of him might be from fourteen to fifteen thousand feet high, and he called it Mount Edwin Arnold. What is so extraordinary about the matter is that he relates (as though he disbelieved them) the stories of the natives to the effect that white stuff and intense cold characterised the upper parts of this mountain range, yet he evinced little or no curiosity to ascertain the truth of these statements. Of course at the time of his visit all the thirty miles of snow and glaciers were concealed under heavy clouds. From the vicinity of Ruwenzori the party made its way to Lake Dweru, which Stanley named Beatrice Gulf. This he learned from the natives was (as it is) but a loop of a much larger lake. Years afterwards Stanley was to realise that he had discovered a portion of Lake Albert Edward. Quitting these regions of mysterious lakes and mountains, he journeyed much more prosaically past the volcanoes of Mfumbiro and the Hima kingdoms of Karagwe to Lake Tanganyika, which he reached at Ujiji on its northeast coast. On this portion of the journey Stanley added a good deal to our information regarding the ultimate source of the Nile, the Kagera, though he was somewhat misled by native information, and perhaps by exaggerated swamps, into the creation of a non-existing lake, which he called the Alexandra Nyanza. His subsequent route across Africa from Tanganyika to the mouth of the Congo does not concern the present narrative. One interesting result of Stanley’s explorations of the Victoria Nyanza, Uganda, and Unyamwezi was that Mr. (now Sir Edwin) Arnold[91] was inspired to propose a Cape-to-Cairo overland telegraph wire to pass via the Zambezi, Lakes Nyasa and Tanganyika, to Uganda and the Egyptian Sudan, thereby forestalling both Cecil Rhodes and the author of this book in the advocacy of a continuous line of British communications between South Africa and Egypt.
