AFRICA AND ITS EXPLORATION. 
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 north- 
eastern 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 Ivivo, which he saicl is as long as from Mugi- 
hawa to Mugere, and as broad as from Mugihawa to 
Warumashanya’s country, or, say eighteen miles in 
length by about eight in breadth. The lake is sur- 
rounded by mountains on the western and northern 
sides : on the south-western side of one of these moun- 
tains 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. 
After so many minute details about the River Rusizi, 
it only remained for us to see it. On the second morn- 
ing of our arrival at Mugihewa we mustered ten strong 
paddlers, and set out to explore the head of the lake 
and the mouth of the Rusizi. We found that the
