series. In the Drakensbergj as in the rest of Natal, the veld 

 grassland occupies by far the largest area. The bush is strictly 

 confined by the climatic factors and occupies the south-eastern 

 slopes where there is sufficient gradient. It will be seen, 

 therefore, that in this case the climate is determined by the 

 topography. 



Bush and veld compete in the occupation of the river-beds, 

 and, if the climatic factors permit, in places we get a distinct 

 type of bush — the Stream Bank type. 



The Protea veld is particularly interesting as being a type 

 intermediate between bush and veld. 



The accompanying diagram illustrates the inter-relationships 

 of the Drakensberg vegetation, and the writer hopes shortly to 

 extend it to the rest of Natal after certain points regarding 

 the coast-belt have been reinvestigated.
