The question, "Was the Rusizi an effluent or an influent?" was answered for ever. There was now no doubt any more on that point. In size it was not to be compared with the Malagarazi River, neither is it, or can it be, navigable for anything but the smallest canoes. The only thing remarkable about it is that it abounds in crocodiles, but not one hippopotamus was seen; which may be taken as another evidence of its shallowness. The bays to the east of the Rusizi are of the same conformation as those on the west. Carefully judging from the width of the several bays from point to point, and of the several spits which separate them, the breadth of the lake may be said to be about twelve or fourteen miles. Had we contented ourselves with simply looking at the conformation, and the meeting of the eastern and western ranges, we should have said that the lake ended in a point, as Captain Speke has sketched it on his map. But its exploration dissolved that idea. Chamati Hill is the extreme northern termination of the western range, and seems, upon a superficial examination, to abut against the Ramata mountains of the eastern range, which are opposite Chamati; but a valley about a mile in breadth separates the two ranges, and through this valley the Rusizi flows towards the lake.* Though Chamati terminates the western range, the eastern range continues for miles beyond, north-westerly. After its issue from this broad gorge, the Rusizi runs seemingly in a broad and mighty stream, through a wide alluvial plain, its own formation, in a hundred channels, until, approaching the lake, it flows into it by three channels only, as above described. ______________ * After the patient investigation of the North end of the Lake, and satisfying ourselves by personal observation that the Rusizi ran into the Lake, the native rumor which Sir Samuel Baker brought home that the Tanganika and the Albert N'Yanza have a water connection still finds many believers! ______________ I should not omit to state here, that though the Doctor and I have had to contend against the strong current of the Rusizi River, as it flowed swift and strong INTO the Tanganika, the Doctor still adheres to the conviction that, whatever part the Rusizi plays, there must be an outlet to the Tanganika somewhere, from the fact that all fresh-water lakes have outlets, The Doctor is able to state his opinions and reasons far better than I can find for him; and, lest I misconstrue the subject, I shall leave it until he has an opportunity to explain them himself; which his great knowledge of Africa will enable him to do with advantage.
