 than average amounts of lime and magnesia, together with fair 

 quantities of potash and phosphoric oxide. If not too chiyey the soils 

 are usually of high fertility, and, generally speaking, dolerite 

 exercises a favourable infiuenre on the fertility ol the soils derived 

 from the sandstones, niuds;tones, and shales of the Stormhorg series of 

 rocks. This influence is to he seen on I'aardenverlies.

 nioieover, the lowest in altitude; its climate is iiieiefore not (juite so

The homestead (vitJc Plate IV) is situated to the left oi' the road 

 as one goes from Burghersdorp to Witkop Post Office, and lies under 

 a characteristic kop which is built up of Molteno beds crowned with a 

 dolerite sheet. This mountain is an outlier of a (diain that runs north- 

 westward towards Konimandant's Kop. 



Black soils of reputed high fertility and suitability lor wheat- 

 growing lie at the foot of this range; their fertility is doubtless due 

 to the effect of the dolerite sheet with which the range is (.-apped, and 

 which seems to have weathered considerably. These soils were not 

 sampled. 



On the opposite side of the road there is a large area of sand-bult 

 soil of low fertility lying over the Molteno beds; it is light })rownisli
