My first objection has been amply discussed. I therefore proceed to consider the second. As Mr. Alexander G. Findlay observed ("Proceedings of the Royal Geographical Society," No. 3, vol. xvii. of July 28, 1873):--"Up to the time of Stanley's arrival at Ujiji, and his journey to the north of the lake, Livingstone was fully impressed with the conviction that the Tanganyika is nothing more than what he called a ‘lacustrine river' (329 miles long by twenty of average breadth); flowing steadily to the north and forming a portion of the Great Nile Basin. The letters contained his reasons for forming that opinion, stating that he had been for weeks and months on the shores of the lake watching the flow of the water northwards" (at the rate of a knot per hour). At times the current appeared to run southwards, but that was under the influence of strong northerly winds. Also by Dr. Livingstone's letters to Sir Thomas Maclear and Dr. Mann (" Proceedings of the Royal Geographical Society,"No. i of 1873, pp. 69-70), it is evident that the explorer believed only in the lake outlet north of Ujiji. Again, Mr. Findlay, after attentively considering the unsatisfactory visit of Dr. Livingstone and Mr. Stanley to the Rusizi River in November and December, 1871, holds it to be a mere marsh-drain, which when the south winds prevail, would possibly flow in the opposite direction; and he still believes that Captain Speke and I, when at Uvira, were within five or six miles of the head. Since Dr. Livingstone's visit we have heard more upon this disputed subject. A native of Karagwah assured my friend Sir Samuel Baker--who, despite all prepossessions, candidly accepted the statement--that it is possible and feasible to canoe from Chibero,on the so-called Albert Nyanza, past Uvira, where the stream narrows and where a pilot is required, to the Arab dépôt, Ujiji. He described the northern portion of the Tanganyika as varying much in breadth, immensely wide beyond Vacovia, and again contracting at Uvira. His report was confirmed by a Msawahíli, sent by King Mtesa, with whom he had lived many years, to communicate with Baker Pasha at Fatiko; this man knew both Uvira and Ujiji, which he called "Uyiyi." Nothing can be more substantial than this double testimony, which wears all the semblance of truth.
