100 TRAVEL, ADVENTURE, AND SPORT. 



think of no better comparison for the surface of this 

 high land than the long sweeping waves of the At- 

 lantic Ocean ; and where the hills are fewest, and in 

 lines, they resemble small breakers curling on the tops 

 of the rollers, all irregularly arranged, as though dis- 

 turbed by different currents of wind. Where the hills 

 are grouped, they remind me of a small chopping sea 

 in the Bristol Channel. That the hills are nowhere 

 high, is proved by the total absence of any rivers 

 along this line, until the lake is reached; and the 

 passages between or over them are everywhere grad- 

 ual in their rise ; so that in travelling through the 

 country, no matter in which direction, the hills sel- 

 dom interfere with the line of march. The flats and 

 hollows are well peopled, and cattle and cultivation 

 are everywhere abundant. The stone, soil, and aspect 

 of this tract is uniform throughout. The stone is 

 chiefly granite, the rugged rocks of which lie like 

 knobs of sugar over the surface of the little hills, 

 intermingled with sandstone in a highly ferruginous 

 state ; whilst the soil is an accumulation of sand the 

 same colour as the stone, a light brownish grey, and 

 appears as if it were formed of disintegrated particles 

 of the rocks worn off by time and weathering. Small 

 trees and brushwood cover all the outcropping hills ; 

 and palms on the plains, though few and widely 

 spread, prove that water is very near the surface. 

 Springs, too, are numerous, and generally distributed.
