He christened the falling effluent, where it drops from the level of the lake and escapes northerly into the Victoria Nile, “Ripon Falls,” in honour of the Earl of Ripon, who was President of the Royal Geographical Society when the expedition was organised, and the arm of the lake from which the Victoria Nile issued, Napoleon Channel, as a token of respect to the Paris Geographical Society, who had honoured him with a gold medal for the discovery of Lake Victoria. Following this paragraph, Captain Speke makes an important statement, to which I beg attention: “One thing seemed at first perplexing, the volume of water in the Kitangule (Alexandra Nile) looked as large as the Nile (Victoria), but then the one was a slow river, and the other swift, and on this account I could form no adequate judgment of their relative values.” On the 4th of June, Captain Speke and Grant embarked at Alexandria, Egypt, for England, where they arrived after an absence of 1146 days. Though one might suppose that the explorers had sufficient grounds for supposing that Lake Victoria covered an enormous area, quite as large, or, approaching to the 29,000 square miles’ extent Captain Speke boldly sketched it, there were not wanting many talented men to dispute each point in the assertions he made. One of the boldest who took opposing views to Speke was his quondam companion, Captain R. F. Burton, and he was supported by very many others, for very plausible reasons, which cannot, however, be touched upon here. Doctor David Livingstone, while on his last expedition, obtained much oral information in the interior of Africa from Arab traders, which dissected Speke’s Grand Lake into five; and it really seemed as if, from the constant assaults made upon it by geographers and cartographers, it would in time be erased from the chart altogether, or become a mere “rush drain,” like one of those which Speke and Grant found so numerous in that region. It was evident, therefore, that a thorough exploration of Lake Victoria was absolutely necessary to set at rest, once and for ever, one of the great problems that was such a source of trouble and dissatisfaction to the geographers of Europe and America. LAKE TANGANIKA AGAIN. The next European to arrive at the shores of Lake Tanganika, after Burton and Speke, was Dr. David Livingstone. He first saw it as he stood on the verge of the plateau which rises steeply from the surface of the Tanganika at its south-west corner, on the 2nd of April, 1867; and on the 14th of March, 1869, and after traversing nearly the whole of the western shore from the extreme south end of the lake to Kassengé, the island which Speke visited in 1858, he crossed over to the east side and reached Ujiji.
