broken by isolated granite peaks, and opening out southwards into wide cotton-soil plains. It isbadly watered, but much grain is grown near the hills.

In the south rises Mount Debasien ( about 10,000 ft. ) , and on the east the country is bounded by the escarp ment of theTurkwel-Lake Rudolf depression . The - lofty Moruasokor and PelegechMountains, on the east,

are inhabited, like the whole of the arid thorn -covered plains west of Lake Rudolf, by the Turkana and their numerous flocks.

River System

The whole territory, with the exception of the

eastern frontier districts which border Lake Rudolf,

forms a single drainage area . Lake Albert and the

tier for almost its entire course, and enters Buganda a few miles above its mouth . The River Katonga, which enters the lake at its north -western corner , consists of

a chain of swamps and lakes . East of this there are no affluents of the slightest importance until the eastern frontier is reached at the River Sio .

(2 ) The Victoria Nile, which forms the outlet to Victoria Nvanza, leaves the lake at the northern end of the Napoleon Gulf . For 61 miles, as far as Kakindu, it is unnavigable, but thence to Foweira , ' a distance of

160 miles ( part of which lies through Lake Kioga ), it is an important waterway . Below Foweira is a series of rapids which terminate above Fajao in the Murchison Falls , where the river descends 140 ft. in a

single fall. From here to Lake Albert it is broad and
