While Lieutenant Burton preferred to rest in Unyanyembé to collect the copious information about the Lake Regions from the Arabs and natives, which we see set forth in a masterly manner in his book, Lieutenant Speke, of a more active disposition, mustered a small force of men, and, with his superior’s permission, set out northward on July 9, 1858, on an exploring tour, and on the 30th of the same month arrived at the south end of a lake called by the Wanyamwezi who were with him the N’yanza, or the Lake, and by the Arabs, Ukerewé. ---------------------------------------------------------------- MAPPA DE KRAPF, REBMANN, LIVINGSTONE, & ERHARDT — 1849-56.

In his reflections on the magnitude of the water expanse before him, Speke wrote: “I no longer felt any doubt that the lake at my feet gave birth to that interesting river, the source of which has been the subject of so much speculation, and the object of so many explorers.” * * * * * * And again: “This is a far more extensive lake than the Tanganika; so broad you could not see across it, and so long that nobody knew its length.” To this magnificent lake Lieutenant Speke, its discoverer, gave the name of Victoria N’yanza. From this short view of the Victoria Lake, Speke returned to Unyanyembé, and announced to Lieutenant Burton that he had discovered the source of the White Nile. Lieutenant Burton did not acquiesce in his companion’s views of the importance of the discovery, and in his ‘Lake Regions’ and ‘Nile Basins,’ in lectures, speeches, and essays in magazines, and conversations with friends, always vigorously combated the theory. On the 30th of February, 1859, Burton and Speke’s task of exploration, which had occupied twenty-five months, terminated with the arrival of the expedition at the little maritime village of Konduchi, on the Indian Ocean. * * * * * * On opening John Hanning Speke’s book, ‘Journal of the Discovery of the Source of the Nile,’ we are informed on the very first page that his second important expedition into Africa, “which was avowedly for the purpose of establishing the truth of the assertion that the Victoria N’yanza (which he discovered on the 30th of July, 1858) would eventually prove to be the source of the Nile, may be said to have commenced on the 9th of May, 1859, the first day of his return to England from his last expedition, when, at the invitation of Sir Roderick Impey Murchison, he called at his house to show him his map, for the information of the Royal Geographical Society.”
