Peaks of the Central Group. 



Presently the sun appeared again below these clouds and 

 lit up the western sky, the ^'alley, and the vast forest of 

 the Congo, which merged in the intense red of the far-off 

 horizon. 



On the following morning, Laurent Petigax, Brocherel, and 

 three native porters went back to fetcli the loads which liud 

 been left on the ])receding day on the pass when they came 

 up from Bujongold. Tlie otliers set ont on the march carrying 

 the rest. They skirted the two little lakes at the foot of the 

 slopes of Kiyanja, cutting their way step by step through 

 the dense tangle of senecio and lirlichrysum. Between 

 the thickets of sempervivum were found specimens of an 

 exceedingly beautiful large flowering hypericum, together 

 witli ranimculus, several plants of tlie cruciferous family, 

 alchemilla, balsam, robbia, etc. The vallev was narrow and 

 grim, shut in between steep rocks, diver than the Mobuku, 

 and showing many and clear traces of glacier action at a not 

 very remote ])eri()(l. The wliole l)ottom Avas full of moraine 

 rubbish, mingled with detritus, fallen from Kiyanja. Both 

 lakes are of glacial formation. Under the lower lake lies 

 a frontal moraine forming a dam, witli a spur of rounded 

 rock. The two lakes are divided l)y a rocky transversal 

 ridge covered with detritus. Tt) the north of the upper lake 

 lies another moraine forming a steep bank, above which a 

 higii plain slopes upward. Here the valley widens out about 

 two-thirds of a mile. At the toot of Kiyanja is a long 

 neve, formed by avalanches falling over the side. 



The valley is dominated by the southern peaks of the 

 central group, from wliicli flovr down two glaciers, forming 

 two sources of the torrent ; the third springs from a glacier 

 of Kiyanja.
