collected. At the same time a selection has been made of soils taken from 

 localities where the influence of the Stormberg and Burghersdorp forma- 

 tions was most likely to have been traced in the composition of the soil. 

 These are comprised in the following table:

The most remarkable feature about these soils is that they are all very 

 uniform in texture and fine in grain, as may be noticed on glancing down 

 the column headed " fine earth." The effect of the calcareous rocks is seen 

 in the relatively large proportions of lime in some of the soils; their 

 irregular occurrence in the very small percentages exhibited by some others. 

 There is, in fact, much less range in the potash than in the lime of these 

 soils. 



The averages for these Burghersdorp and Stormberg soils are as 

 follows : 



Lime '233 



Potash -172 



Phosphoric oxide '078 



The next class of soils that we have to deal with belongs to the Uiten- 

 hage series, and more particularly to the geological base of that series, 

 namely, the Enon conglomerate. This formation is of a more recent date 

 than any of those previously considered, and we here pass from the Karroo 

 to the Cretaceous system. The Uitenhage series consists of shales, clays 

 and sandstones, with limestone bands and marls. A fair proportion of lime
