84 REGENERATION OF THE DARK CONTINENT. 



the fourth in size of the continent, and having in its course the 

 Victoria Falls, one of the greatest waterfalls in the world. 



In Southern Africa also but flowing westward and entering 

 the Atlantic, is the Kongo, which takes origin from a series of lakes 

 and marshes in the interior, is fed by great tributaries, and is the 

 first in volume of all the African rivers, carrying to the ocean more 

 water than the Mississippi. Unlike most of the African rivers, 

 the mouth of the Kongo forms an estuary. Of the other Atlantic 

 rivers, the Senegal, the Gambia and the Niger are the largest, the 

 last being third among African streams. 



With the exception of Lake Tchad there are no great lakes 

 in the northern division of Africa, whereas in the number and 

 magnificence of its lakes the southern division almost rivals North 

 America. Here are the Victoria and Albert Nyanza, Lakes Tang- 

 anyika, Nyassa, Shirwa, Bangweolo, Moero, and a few others. 



Of these the Victoria and Albert belong to the basin of the 

 Nile; Tanganyika, Bang-weola, and Moero to that of the Kongo; 

 Nyassa, by its affluent the Shire, to the Sambesi, Lake Tchad on 

 the borders of the Northern desert region, and Lake Ngami on 

 the borders of the southern, have a remarkable resemblance in 

 position, and in the fact that both are drained by streams that lose 

 themselves in the sand.
