THEORIES AND ERRORS loi 



Semliki Valley, obtained photographs from the west 

 side of a double-topped snow-peak which he rightly 

 believed to be the highest in the range. Sir Harry 

 Johnston, who believed that Kiyanja (the peak that 

 we first ascended) was the highest peak, saw also 

 from the Lower Mubiiku Valley another twin-topped 

 snow mountain to the north-east of Kiyanja, which 

 he named Duwoni, and of which there is a beautiful 

 illustration in his book."^' Arrived at the head of 

 the valley, he concluded that the peak, which rose 

 to the right of the Mubuku glacier, was the Duwoni 

 which he had seen from afar. Mr. Douglas 

 Freshfield, who visited Ruwenzori in 1905, obtained 

 a clear view of the range from a distance of about 

 thirty miles to the east, whence he saw and identi 

 fied the reverse of Dr. Stuhlmann's two-topped 

 highest peak. He also saw from the Lower Mubuku 

 Valley Sir H. H. Johnston's two-topped Duwoni, 

 and concluded that it was one and the same thing 

 with the high peak of Dr. Stuhlmann. Like Sir 

 Harry Johnston, Mr. Freshfield also believed f that 

 Duwoni was the peak which rose immediately 

 above the Mubuku glacier on its north-east side. 

 It was abundantly proved by the view which we 

 obtained from Kiyanja that the two high snow- 

 peaks seen to the north-west could not be identical 

 with Duwoni, which lay to the north-east of Kiyanja, 

 while at the same time we had no doubt that the
