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 depot, 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 Msawahili, 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.

On the other hand, Lieut.  Cameron, whose admirable work has, so to speak, re-constructed the Tanganyika Lake, discovered, on the 3rd of May, 18-74, the Lukuga River, which he supposes to form the outlet.  It lies 25 direct miles to the south of the Kasenge Archipelago, numbering seventeen isles, visited by Captain Speke in March, 1857.  Dr. Livingstone touched here on July 13, 1869, and heard nothing of the outlet; he describes a current sweeping round Kasenge to south-east or southwards according to the wind, and carrying trees at the rate of a knot an hour.  But Mr. Stanley (pp. 400 et passim) agrees with Dr. Krapf, who made a large river issue from “the lake” westwards, and who proposed, by following its course, to reach the Atlantic.  The “discoverer of Livingstone” evidently inclines to believe that the Tanganyika drains through the caverns of Kabogo near Uguhha, and he records the information of native travellers that “Kabogo is a great mountain on the other side of the Tanganyika, full of deep holes, into which the water rolls; “moreover, that at the distance of over a hundred miles he himself heard the” sound of the thundering surf which is said to roll into the caves of Kabogo."In his map he ’cutely avoids inserting anything beyond “Kabogo Mountains, 6,000 to 7,000 feet high.”
