this aversion doubtless indicating that the original home of the animal was in 
desert lands. On this subject Sir Samuel Baker observes, that “ a camel either 
cannot or will not swim, unless it is supported by inflated skins; thus the passage 
of the broad river, Atbara (about 300 yards wide), is an affair of great difficulty. 
Two water-skins are inflated, and attached to the camel by a band passed like 
a girth beneath the belly. Thus arranged, a man sits upon its back, while one or 
two swim by the side as guides. The current of the Atbara runs at a rapid rate; 
and the camel is generally carried at least half a mile down the river before it can 
gain the opposite bank.”

but likewise by its inferior height, stouter and more clumsy build, shorter legs, 
and harder and shorter feet, as well as by the greater length and abundance of the 
hair. This animal is, indeed, in all respects, better adapted for a rocky and hilly 
country than its southern congener; its shorter and stouter limbs rendering it far 
less liable to accidents in traversing precipitous ascents. The largest develop¬ 
ment of hair occurs upon the top of the head, the neck and shoulders, the upper 
part of the fore-limbs, and the humps.
