never succeeded in i;ettiiii;- i'loin the peaks a clear view of tlie 

 valleys to tlic west of tlie oliain so as to ohtaiii an aocnrate 

 idea of tlieir direction and distrilmtion. As far as lie was 

 able to observe, lie formed tlie opinion tliat the fonr valleys 

 ninnini^ down from the Cols Freslifield, Scott Elliot, Stnhlmann, 

 and (Aivalli (marked A, B, C, D on the map) joined toi;ether 

 to form the Butagn Vallev, which would consefjuently 

 collect the waters of tlie western glaciers of Mts. 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 Russirubi and the Iluame Rivers (E and F of the ma})), 

 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 AVimi 

 would not be fed bv glaciers at all. 



With tlie 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 oj^portunities of seeing either the single peaks 

 or the range from tlie nortli, the west, and the south. He left, 

 however, vague records onlv, and clearlv the reality of the 

 picture has been too greatlv altered bv the illustrator of his 

 book to make it possible to determine the individual moimtalns 

 in his illustrations. At the very most it is possil)le to recognize 

 Margherita Peak and Mt. Speke confused in a single group 

 in the view taken from Kavalli to the north of the mountains, 

 and reproduced on ]>. 1^30 of " In Dai-kest Africa," A^ol. II.
