The mechanical analysis shows that the soil is rather more sandy 

 than the saudhult .'-oil from Paardenverlies, i.e. No. G12. Chemically 

 it is slightly different, in that it contains a notable quantity of avail- 

 able potash and a very small quantity (0.03 per cent.) of calcium 

 carbonate. The soil is poorly retentive of water, but, since water 

 moves through it readily, it will always be moist near the surface so 

 long as the sub-soil has not dried out. 



The manurial treatment recommended for this soil is the same as 

 that recommended for the Paardenverlies sandbult soil. (See page 

 441.) 



Complaint was made thnt the use of water from a borehole near 

 the homestead made tlie soil hard. A partial analysis of the water 

 was made with the following results : — 



Total solids 35.2 grams per 100,000 c.c. 



Chlorine 4.6 ,, ,, 



Calcium and magnesium carbonates ... 21.75 ,, 



Sodium carbonate 5.56 



It is possible that the effect complained of was caused by the 

 sodium carbonate. The origin of the carbonates in this water would 

 appear to be, in part at least, the felspar of the dolerite and lava 

 which occurs in the vicinitv.
