CATTLE -BREEDING AND DAIRYING 139 



Between these extremes means should be adopted 

 according to latitude. Last year I observed some 

 wagons at work in the Quelimane district, each 

 drawn by eight oxen, and it was apparent that 

 spans of this size were beyond the capacity of 

 the drivers to control. More work would have 

 been got out of six. It follows from this that 

 wagons, ploughs, and all agricultural implements 

 should undergo a corresponding reduction in 

 weight as we proceed north. 



It will be asked how this is to be accounted 

 for. It is, I think, the enervating influence of 

 the tropic sun which forbids excessive and sus- 

 tained exertion on the part of man or beast, 

 especially of the white man, the source and 

 support of all new activities. Cattle take longer 

 to train in the Tropics than in temperate climates, 

 and the training must be left more to the native, 

 who himself begins by being less intelligent than 

 his black brother of the south, requiring greater 

 attention at the hands of the white man, who 

 again is able to give him not more but less of 

 it. Being unable to provide the requisite energy 

 at one end, it becomes necessary to reduce the 

 task at the other. 



At the coast and also in parts of the interior 

 the docile zebu is well known, but has hardly 

 yet been taken seriously as an agent for im-
