come upon the fresh trail of an exceptionally large 

 rhinoceros. 



The beast has left the track, and probaby has settled 

 down at a distance of not less than three, and perhaps 

 of five or more leaorues, in the desert. 



After sending back the different servants into camp, 

 there remain with me now only those picked carriers 

 who can stand any amount of fatigue and upon whom 

 I can rely most thoroughly for everything. 



I believe my observation to be accurate in this, 

 that the power of enduring thirst is quite difterently 

 developed in the various races and tribes, according to

 any European breed, and for this reason I consider the 

 employment of European horses in South-West Africa,

 natives in this respect. 



It is noteworthy that the native, even when enduring 

 the agony of thirst, is able to get sleep at night, while
