After travelling for six days he reached Ubimba, the frontier of Karagwe, where, behind a ridge which extends between Ubimba and the lake, he saw the extreme south end of the lake he had so long followed, and noticed a decided change in the formation of the broad valley of the Kagera. The mountainous ridges bounding the western shore of the Kagera, which, extending from Mpororo south, continue on a south by west course, became broken and confused in southern Kishakka, and were penetrated from the northwest by a wide valley, through which issued into the Kagera a lake-like river called Akanyaru. Southwest was seen the course of the Kagera, which, above the confluence of the Akanyaru with it, was only a swift-flowing river of no very great depth or breadth. Such a river might well be created by the drainage of eastern Urundi and western Ubba. His attention was drawn from the Kagera to the lake-like stream of Akanyaru, and several natives stated to him while looking toward it that it was an effluent of the Kagera, and that it emptied into the Albert Nyanza. Such an extraordinary statement as this could not be received and transmitted as a fact without being able to corroborate it on his own authority, and exploration of the north of the Akanyaru proved that the Akanyaru is not an effluent but an affluent of the Kagera. Beyond the mouth of the Akanyuru, Stanley found it was impossible for him to go, owing to the determined hostility and opposition of the natives on the right and left banks of the river. Forced to abandon the exploration of Lake Albert from this side of the Tanganyika, he marched in the direction of Ubagwe, in western Unyamwezi, about fifteen days’ journey from Ujiji. He then proposed to proceed quickly to Ujiji, explore the Tanganyika in his boat, and from Uzigo strike north to the Albert; and if that road should not be open, to cross the Tanganyika and travel north by a circuitous course to effect his purpose--the exploration of Lake Albert.
