basin of Luke Kiiisuiiihu to the north and upon wliich are 

 situated Toro and Fort Portal ; the other l)ranch passes to tlie 

 west of tlie ranoje and forms the Seniliki Vallev and the l)asin 

 of Lake Alhei't, and is prolonged for several liundred miles 

 hv the upper vallev of the Nile. lluwenzori is thus neai'lv 

 completely surrounded hy the '' Albertine Depression," and forms 

 with the three lakes an independent hydrographic system 

 absolutelv distinct from that of Lake Victoria. 



Thus it is that this Ruwenzori rano;e sheds the waters of 

 all its slopes east, west, north and south into one and the 

 same rixer basin, feeding almost unassisted the three lakes 

 and the Sendiki, which together form the south-western 

 sources of the Nile. Furthermore, Ruwenzori beino- without 

 doubt the most considerable group of snowy mountains on 

 the African continent, and situated in the middle of that 

 continent, and running in the direction of its main axis, 

 does not form a portion of its main watershed. The actual 

 watershed between the Congo and the Nile consists of a line 

 of low hills, lying at a short distance to the w'est of the 

 Sendiki, and masked l)v the oreat Conp-o forest, running- 

 nortliMard along Lake Albert, prolonged soutll^^■ard in the 

 volcanic chain which forms the dividinof ridsfe of the rift 

 between Lakes Kivu and Albert Edward, and finally skirtino- 

 the eastern shores of Lake Kivu and of Lake Taneanika. 



The Duke of the Abruzzi preserves to the chain the name 

 of lluwenzori, given to it by its first discoverer, Stanley, and 

 adopted since then by the majority of geographers. 



Stanley had heard the natives dwelling to the 

 north and west of these mountains call tliem by tlie 

 names lluwenzori, Ukonju, Bugombowa, Avuruka, Avirika. 

 Ivuwenzuru-ru, lluwenjura, etc. He was of opinion that
