Formation and (Jeneral Features of Kuwenzori. 



The watershed hue starting from the peak to the extreme 

 .south, the Weismauu, runs eastward alono- Mt. Luigi di Savoia, 

 then northwards over Freshtield's Col and along Edward Peak 

 and Semper Peak of Mt. Baker. From this point, making 

 a wide half-circle, it runs along tlie high ridge of the Bujukti 

 Yallev over Scott Elliot's Col, over tlie peaks of Mt. Stanley 

 and Stuhlmann's Col as far as Vittorio Emanuele Peak, tlien 

 descends along the nortli-east ridge of Mt. Speke to Cavalli's 

 Col, traverses the summit of the two parallel groups, Emin and 

 Gessi. cro.ssiug Roccati's Col l)etween them. From lolanda 

 Peak of Mt. Gessi it follows a south-easterly ridue to the 

 groujj of the Portal Peaks, whence it turns north-east again. 



The most important river hasin to the east of the chain 

 is that of the Bujuku Vallev. wliich is sm-rounded hy five 

 mountain liiouns and is fed hy the "leatei' glaciers of Mt. 

 Stanley, Mt. Speke, and Mt. Gessi. The Upper Mobuku 

 Vallev. oil tlip other hand, receive.s only the waters of the 

 Baker glaciers and of a few little glaciers on the eastern side 

 of Mt. Luigi di Savoia through the Mahoma torrent. Hence 

 the MoV)uku River is much smaller than the Bujuku River, 

 and is in reality a mere affluent of it. It would, therefore, be 

 more geographically correct to name the entire valley Bujuku, 

 even if only because the two greater mountains stand at its 

 head as well as Stuhlmann's Col, which is the deepest 

 depression of the whole range and lower than Fre.shfield's 

 Col. The name Mobuku, however, as applied to both river 

 and valley, has lieeii so widely spread by preceding explorers 

 that H.R.H. did not think fit to change it, in order to 

 avoid confusion in the nomenclature. 



The atmosphere around Ruwenzori is .so misty and .so 

 lacking in transparency, even in fine weather, that tlie Duke
