HONEY AND WAX. 393 



horned cattle a different species from the Alderneys or tho 

 Highland breed. I was led to this from having once seen 

 a black rhinoceros with a horn bent downward like that 

 of the kuabaoba, and also because the animals of the two 

 great varieties differ very much in appearance at different 

 stages of their growth. I find, however, that Dr. Smith, 

 the best judge in these matters, is quite decided as to the 

 propriety of the subdivision into three or four species. For 

 common readers it is sufficient to remember that there are 

 two well-defined species, that differ entirely in appearance 

 and food. The absence of both these rhinoceroses among 

 the reticulated rivers in the central valley may easily be 

 accounted for, they would be such an easy prey to the 

 natives in their canoes at the periods of inundation; but 

 one cannot so readily account for the total absence of the 

 giraffe and ostrich on the high open lands of the Batoka 

 north of the Zambesi, unless we give credence to the native 

 report which bounds the country still farther north by 

 another network of waters near Lake Shuia, and suppose 

 that it also prevented their progress southward. The Ba- 

 toka have no name for the giraffe or the ostrich in their lan- 

 guage; yet, as the former exists in considerable numbers 

 in the angle formed by the Leeambye and Chobe, they 

 may have come from the north along the western ridge. 

 The Chobe would seem to have been too narrow to act as 

 an obstacle to the giraffe, supposing it to have come into 

 that district from the south ; but the broad river into 

 which that stream flows seems always to have presented 

 an impassable barrier to both the giraffe and the ostrich, 

 though they abound on its southern border, both in the 

 Kalahari Desert and the country of Mashona. 



The honey-guides were very assiduous in their friendly 

 offices, and enabled my men to get a large quantity of 

 honey. But, though bees abound, the wax of these parts 

 forms no article of trade. In Londa it may be said to be 

 fully cared for, as you find hives placed upon trees in the 

 most lonesome forests. We often met strings of camera
