Chapter VII. 
never succeeded in getting from the peaks a clear view of the 
valleys to the west of the chain so as to obtain an accurate 
idea of their direction and distribution. As far as he was 
able to observe, he formed the opinion that the four valleys 
running down from the Cols Freshfield, Scott Elliot, Stuhlmann, 
and Cavalli (marked A, B, C, D on the map) joined together 
to form the Butagu Valley, which would consequently 
collect the waters of the western glaciers of Mis. Luigi di 
Savoia, Baker, and Stanley, and a great part of those of the 
Speke Glacier and of the glaciers of Mt. Emin. Thus this 
would be the most important of the western valleys. It is 
probable that Mt. Emin and Mt. Gessi contribute to feed 
the Bussirubi and the Ruame Rivers (E and F of the map), 
which, like the Butagu, are affluents of the Semliki, and that 
the southern valley, Nyamwamba, runs up as far as the glaciers 
of Mt. Luigi di Savoia. The torrents Yeria and Wind 
would not be fed by glaciers at all. 
With the help of our precise knowledge of the range we 
may now attempt to collate with one another, and with the 
data furnished by H.R.H., the discoveries and descriptions 
of the preceding explorers. 
Of all these predecessors, Stanley was the one who had 
the most frequent opportunities of seeing either the single peaks 
or the range from the north, the west, and the south. He left, 
however, vague records only, and clearly the reality of the 
picture has been too greatly altered by the illustrator of his 
book to make it possible to determine the individual mountains 
in his illustrations. At the very most it is possible to recognize 
Margherita Peak and Mt. Speke confused in a single group 
in the view taken from Kavalli to the north of the mountains,
