Peaks at the Head of Mobuku Valley. 



torrent. Near to the glacier the only plants are arboraceous 

 senecio, several 3'arcls high. 



A little before the end of the valley the way crosses the 

 torrent and mounts a frontal moraine lett bv the retreating- 

 glacier. In this way a j^rojecting rock is reached where 

 Grauer had encamped at a height of 13,229 feet al)ove the 

 sea, a little lielow the lower end of the glacier. This was the 

 last point where it was possible to liglit a fire, and during 

 the brief lialt the porters huddled shivering around tlie flame. 

 The distance from Bujongolo to this point is one hour's march. 

 The way now continued skirting the rock to the right and 

 ascending a short chimney closed at the top by a boulder, from 

 which still hung one of the ropes placed there by Grauer to 

 facilitate the ascent. Thanks to this assistance the obstacle 

 was easily surmounted. 



In one more hour's climl) up the rocks the left margin of 

 the glacier was reached just above the terminal tall of seracs. 

 Here the way skirted the glacier for a bit, and then proceeded 

 again to climb the rock wall over a diflicult passage, which 

 the porters would have been unable to negotiate Avithout the 

 assistance of the guides. Their bare feet slipped continuallv 

 upon the smooth steep moss-grown slabs of rock, or got 

 wounded on their edges and sharp points. At last the Duke 

 gave up the idea of bringing them further and sent them 

 back to Bujongolo. 



A short traverse led back to the glacier at the foot of a 

 rocky projection. The Duke had wished to encamp on tlie top 

 of the ridge so as to be there at the following dawn A\'hen 

 there was greater chance of a clear sky. But hardly had 

 they reached the glacier before a dense fog enveloped the 

 party and shut out everything from their sight. It was
