A BOUNDARY QUESTION 127 



error which persists about the lake is the name 

 Ruisamba, which is quite unknown to any of the 

 inhabitants of its shores : they call it variously 

 Dweru, Kafuru, and Bulima in its different parts, 

 but never Ruisamba. However, it has, like 

 Ruwenzori, a pleasing sound, and may well be 

 adopted. 



A steep descent through a partly cultivated 

 country on the farther side of the hills brought us 

 down to the level plains, which lie between the 

 waters of the Nyanza on the south and the heights 

 of Ruwenzori on the north, and are only separated 

 from the plains of the Semliki Valley by one low 

 ridge — a long south-westerly spur of Ruwenzori. 

 This district is one to which a considerable import-

 the fact that the ownership of it is uncertain. When 

 this part of Central Africa was divided up, the 

 thirtieth parallel of longitude was taken as the 

 boundary between Uganda and the Congo Free 

 State. Thus Uganda claimed the east and part 

 of the north shore of Lake Albert Edward (in- 

 cluding Katwe and its valuable salt lake), nearly the 

 whole of Ruwenzori, and the Lower Semliki Valley ; 

 while the west side of the Nyanza and the Upper 

 Semliki Valley were recognized as a part of the 

 Congo Free State. Unfortunately, a more recent 

 and more accurate survey has discovered that the 

 thirtieth parallel actually lies some ten or twelve 

 miles to the east of where it was formerly thought
