Physical Features and Climate. The Nile has its source in three great lakes (Victoria,about as big as Scotland, Albert Edward and Albert),situated near the equator. At Gondokoro the riverleaves the hi^h plateau for_lhc lower Sudan plateau,and as it falls only 2T5 feet in Fts i,000-mUe Journeybetween Gondokoro and Khartoum, it becomes a broad,sluggish stream, forming large lagoons choked by sudd THE NILE LANDS 477 or floatinc; marsh vegetation, which very considerably 11.

Between Khartoum and Aswan theriver falls nearly i,oco feet, chiefly in six cataracts causedby transverse reefs of granite and other hard rocks (seeF^g- 130- These cataracts impede navigation, except atthe flood season, when they are covered with Aswan the course again becomes gentle, and theriver is navigable right to the sea. In the region of the equatorial sources, the heavyrainfall plus the drainage of the permanent snow-fieldsof the Ruvvenzori group ensure that the discharge ofwater from Lakes Victoria, Albert Edward and Albertwill be fairly regular. On leaving the lakes plateau theriver enters a region of summer rainfall. At
