Formation and General Features of Ruwenzori. 



Lower Mobukii Valley he saw a great snowy inoiiiitaiii which 

 he named Duwoni. He gives a fine illustration of this moun- 

 tain on p. 158 of his hook. There is no doubt that this 

 is to be identified with Mt. Speke. On reaching Bujongolo 

 he believed himself to have reached the foot of this same 

 Duwoni, whereas in reality he had been going further from 

 it from Nakitawa onward. He furthermore believed that 

 Mt. Kiyanja (Baker) was Mt. Semper of Stuhlmann, and that 

 Duwoni (Speke) was Peak Weismann. 



Mr. Freshfield, as well as the Duke, was able to have a 

 complete view of the range from Butiti, on the way between 

 Entebbe and Fort Portal. He enumerates "'• the mountains of 

 Ruwenzori as follows, from left to right : — 1st, a massive rocky 

 group with patches of snow, which he calls South Peak, and 

 which is Mt. Luigi di Savoia ; 2nd, a wide col, which is the 

 col above the Mobuku Valley which now bears his name ; 3rd, 

 a bold peak of rock and glacier, the Kiyanja of Johnston ; 

 4th, the undulating ridge covered with glacier which from 

 this last group leads to the highest snow peak, and which 

 Mr. Freshfield takes to be the Duwoni of Johnston, but which 

 is in reality Margherita Peak. Duwoni or Speke, as a matter 

 of fact, does not appear as an isolated mountain when seen 

 from Butiti, but seems to form a single groujD with Mt. Stanley. 

 It may be of use to the reader at this j)oint to compare 

 Mr. Freshfield's description with the outline of the range as 

 seen from Butiti, taken from Sella's tele-photograph, and with 

 the addition of the new names. On reachinof the head of the 

 Mobuku Valley, Mr. Freshfield would appear to have fallen into 

 the same error as his predecessors, for he describes it as
