flows the Back river, with two outlets. The Great Fish river 
country of granite, gneiss and trap, drained by numerous tribu- 
taries of the Great Fish river. The coast west of these mountains 
is a sandy desert, extending seventy miles inland. The upper 
courses of the Swakop, Kuisip and Omaruru are in a fertile coun- 
try, among granite mountains, some of which attain an attitude 
of about 9000 feet, but the lower courses of these rivers pass 
the Kalahara desert, is a high table-land, and is very healthy. 
Kalahara desert scarcely seems to be a desert in the usual 
sense of the word, but to be almost wholly a level, swampy region, 
with much jungle and many salt-pans. The rivers and salt-pans 
are, to a great extent, dry during much of the year, and the region 
s very unhealthy. Bushmen are the principal inhabitants. The 
‘ern part of the belt surveyed, north of the Orange river, is 
drained by the Limpopo or Crocodile river, the sources of which 
are on the northern slope of the great water-shed that runs across 
y and park-like valleys. Other important tributaries entering 
the Limpopo from the Matabele country to the north of it, are
