The country bordering the head of the lake from Urundi proper, on the eastern shore, to Uvira on the western, is divided into the following districts: 1st. Mugere, governed by Mukamba, through which issued into the lake the small rivers of Mugere and Mpanda. 2nd. Mukanigi, governed by Warumashanya, which occupied the whole of the north-eastern head of the lake, through which issued into the lake the small rivers of Karindwa and Mugera wa Kanigi. 3rd. On the eastern half of the district, at the head of the lake, was Usumbura, governed by Simveh, ally and friend of Warumashanya, extending to the eastern bank of the Rusizi. 4th. Commencing from the western bank of the Rusizi, to the extreme north-western head of the lake, was Mugihewa--Ruhinga's country. 5th. From Uvira on the west, running north past Mugihewa, and overlapping it on the north side as far as the hills of Chamati, was Ruwenga, also a country governed by Mukamba. Beyond Ruwenga, from the hills of Chamati to the Ruanda River, was the country of Chamati. West of Ruwenga, comprising all the mountains for two days' journey in that direction, was Uashi. These are the smaller sub-divisions of what is commonly known as Ruwenga and Usige. Ruwenga comprises the countries of Ruwenga and Mugihewa; Usige, the countries of Usumbura, Mukanigi, and Mugere. But all these countries are only part and parcel of Urundi, which comprises all that country bordering the lake from Mshala River, on the eastern shore, to Uvira, on the western, extending over ten days' journey direct north from the head of the lake, and one month in a northeastern direction to Murukuko, the capital of Mwezi, Sultan of all Urundi. Direct north of Urundi is Ruanda; also a very large country. The Rusizi River--according to Ruhinga--rose near a lake called Kivo, which he said is as long as from Mugihawa to Mugere, and as broad as from Mugihewa to Warumashanya's country, or, say eighteen miles in length by about eight in breadth. The lake is surrounded by mountains on the western and northern sides: on the south-western side of one of these mountains issues the Rusizi--at first a small rapid stream; but as it proceeds towards the lake it receives the rivers Kagunissi, Kaburan, Mohira, Nyamagana, Nyakagunda, Ruviro, Rofubu, Kavimvira, Myove, Ruhuha, Mukindu, Sange, Rubirizi, Kiriba, and, lastly, the Ruanda River, which seems to be the largest of them all. Kivo Lake is so called from the country in which it is situated. On one side is Mutumbi (probably the Utumbi of Speke and Baker), on the west is Ruanda; on the east is Urundi. The name of the chief of Kivo is Kwansibura.
