Formation and General Features of Ruwenzori. 
Lower Mobuku Valley he saw a great snowy mountain which 
he named Duwoni. He gives a fine illustration of this moun¬ 
tain on p. 158 of his book. 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 group with Mt. Stanley. 
It may be of use to the reader at this point 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 reachino- the head of the 
O 
Mobuku Valley, Mr. Freshfield would appear to have fallen into 
the same error as his predecessors, for he describes it as

Journal,” May, 1906, Yol. XXVII, p. 481.
