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.
One thing is evident to me, and I believe to the Doctor, that Sir Samuel Baker will have to curtail the Albert N’Yanza by one, if not two degrees of latitude. That well-known traveller has drawn his lake far into the territory of the Warundi, while Ruanda has been placed on the eastern side; whereas a large portion of it, if not all, should be placed north of what he has designated on his map as Usige. The information of such an intelligent man as Ruhinga is not to be despised; for, if Lake Albert came within a hundred miles of the Tanganika, he would surely have heard of its existence, even if he had not seen it himself. Originally he came from Mutumbi, and he has travelled from that country into Mugihewa, the district he now governs. He has seen Mwezi, the great King of Urundi, and describes him as a man about forty years old, and as a very good man.
Our work was now done; there was nothing more to detain us at Mugihewa. Ruhinga had been exceedingly kind, and given us one ox after another to butcher and eat. Mukamba had done the same. Their women had supplied us with an abundance of milk and butter, and we had now bounteous supplies of both.
The Doctor had taken a series of observations for latitude and longitude; and Mugihewa was made out to be in 3 degrees 19 minutes S. latitude.
On the 7th December, early in the morning, we left Mugihewa, and rowing past the southern extremity of the Katangara Islands, we approached the highlands of Uashi near the boundary line between Mukamba’s country and Uvira. The boundary line is supposed to be a wide ravine, in the depths of which is a grove of tall, beautiful, and straight-stemmed trees, out of which the natives make their canoes.
Passing Kanyamabengu River, which issues into the lake close to the market-ground of Kirabula, the extreme point of Burton and Speke’s explorations of the Tanganika, we steered south along the western shore of the lake for half an hour longer to Kavimba, where we halted to cook breakfast.
