Chapter YI. 
Mobuku Glacier. From the col which they had just traversed, 
a nearly perpendicular rock wall falls down to this valley on 
the north. The eye followed the valley for a long distance 
eastward and saw it turn southward in the distance to join 
the Mobuku. Thus there remained no possible doubt as to 
this being really the Bujuku Valley, and as to the great 
snowy mountain to the north being really the Duwoni of 
Johnston. To the south-east the view is shut out by the 
mass of Kiyanja. 
The guides who had climbed the glacier to make out 
the way to the central group returned towards evening. 
The sunset was less clear than on the preceding days. The 
extreme nearness of the goal made the forced delay intolerable. 
The Duke, cooped up with the guides in the narrow space 
of a single tent, passed a great portion of the night in 
anxious watching, preoccupied by disagreeable doubts as to 
the weather. 
Finally, the day dawned on the 18th of June with a clouded 
grey sky. They roped together hastily and in silence. Joseph 
Petigax and Ollier came first, then the Duke, and lastly, 
Brocherel. They began the ascent of the glacier along the 
way traced by the guides on the preceding day. The great 
ice plain was reached without difficulty in about one hour. 
It was 6.30 in the morning, and the peaks which they desired 
to reach stood before them at a very short distance. They 
were both covered with snow, and the southernmost, which 
stood nearest to them, showed a rock precipice on the east 
side surmounted by a big cornice of snow and was joined 
by a rounded ice col to the northern peak, which was some¬ 
what higher, and from which ran down two ridges, one 
eastward in a straight line towards the valley, the other north-
