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, Bangweola, 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.
