The neighbourhood of Zongweh Cape is specially distinguished for its lofty cones and great mountain masses. Mount Murumbi, 2000 feet above the lake, near Muri-Kiassi Cape, is a striking feature of the coast of Marungu. The wooded slopes and dense forest growths which fill the gorges are haunts of what the Wangwana call “Soko,” a distinctive title they have given either to gorillas or chimpanzees. I heard the voices of several at Lunangwa river, but as they were at a considerable distance from me, I could not distinguish any great difference between the noise they created and that which a number of villagers might make while quarrelling. The Rubuko, or Lofuko, a considerable river, divides Marungu from Tembwé. On the south side of the river is Mompara, or, for short, Para, remarkable as being the place whereat Livingstone embarked in canoes, February 1869, to proceed to Ujiji for the first time (‘Last Journals,’ vol. ii.):— “_14th February, 1869._—Arrived at Tanganika. Parra is the name of the land at the confluence of the river Lofuko.” The chief of the Para village is patronised by Jumah Merikani, who, while he is absent in Rua collecting slaves and ivory, entrusts his canoes to the chief’s charge, from which it appears that the latter is a trustworthy man. Formerly Sheikh Sayid bin Habib honoured him with the same confidence. Four hours’ sail brought us to the wooded headlands of Tembwé, the most projecting of which is about twenty-five miles from Makokomo Island, in the Bay of Kirando, on the east coast of the lake. Near this point is seen a lofty range, rising a few miles from the lake in an irregular line of peaks, which, as it is depressed towards the north, presents a more arid appearance, and presently forms a range of a much lower altitude than the mountains of Tongwé, Fipa, Urungu, or Marungu. This continues—with gaps here and there for rivers to escape through to the lake—until a little north of Kasengé Island, where it rises again into the mountains of Goma, the highest of all round Lake Tanganika. At Kankindwa, which is in a little cove near Tembwé Cape, a native told us that the Lukuga flowed _out_ of the lake to Rua; another denied that flatly, and a third said that the Lukuga flowed out of the lake towards Rua, but that, meeting another river descending towards the Tanganika, it was stopped, and the two rivers formed a lake. _July 14._—As we sailed north from Tembwé and observed the comparatively low altitude of the Uguha range, I began to feel that it was, of all the countries we had seen, the most likely to have a gap for the escape of the waters. It reminded me of some parts of Usukuma, on Lake Victoria. We explored the mouths of the Ruanda, Kasenga, Ruwye-ya, Rutuku, and Kahanda rivers, and then from Mirembwé Cape sailed for the Lukuga—the river that formed now the most interesting object of our exploration.
