Formation and General Features of Iluwenzori. 
The general direction is north and south, and the shape is very 
nearly that of a written G. The principal groups would 
compose the main curve of the G, while one group only, 
that farthest south, would represent the tail of the letter. 
The range consists of six mountains, i.e., groups of peaks 
with glaciers, divided from one another by cols without snow, 
and therefore quite clearly distinct from one another. The 
area actually covered by glaciers is a little more than seven 
miles long in a straight line from south to north, and about 
four miles wide from east to west. The length of the watershed 
ridge, including all the groups, that is to say, the entire snowy 
range, is about 11 miles long. 
The chain begins in the north with two groups, two parallel 
snow ridges running nearly due north and south. The eastern¬ 
most of these was named by the Duke Mt. Gessi, in memory 
of the Italian explorer who was the first to circumnavigate 
Lake Albert. The western group was named Mt. Emin, after 
Emin Pasha, who traversed the Semliki Valley for the first 
time with Stanley. 
Mt. Emin joins Mt. Speke, which bears the name of the 
first discoverer of the sources of the Nile in Lake Victoria. 
After Mt. Speke the chain turns westward, rises to the highest 
group, rightly called Mt. Stanley, and sweeps around in an 
eastward curve to the group which bears the name of Baker, 
the discoverer of Lake Albert, who had the first glimpse of 
the mountain ranges of Ruwenzori. 
Last of all, the group to the south of Mt. Baker, which 
runs from north-east to south-west, had been called by H.B.H. 
Mt. Thomson, in memory of J. Thomson, whose work in Nigeria 
is well known. But after his return to Europe the Duke was 
forced to yield to the proposal of the English Geographical
