It is to be expected that the method whereby most of the soils from 

 ~this division have been analysed will yield higher proportions of lime and 

 potash than in the case of soil-extraction by Method I. ; to exemplify this 

 the analytical results given in the above table for the poor sour soil at 

 Helming Bosch (No. 5) should be compared with the analyses of similar 

 sandstone-derived soils extracted by Method I. The results obtained 

 from the Hartenbosch and Patrysfontein soils (Nos. 16 and 17) should 

 .Also be thus compared.

Two very poor gravelly soils were sampled at Tiger Valley; these 

 are represented in the above list by samples 1 and 2. Nos. 3 and 4 were 

 collected on the farm Poortje, near Kokstad. The soil, which is peaty, 

 is about a foot deep, generally overlying red clay, although in some cases 

 resting upon yellow shale. Some 200 acres had been ploughed up, but 

 the agricultural capabilities of the land had proved disappointing, 



The following results were obtained by analysis of the above four

The disappointing character of the agricultural returns obtained from 

 Noe. 3 and 4 exemplifies at the same time the value of chemical analysis 

 as a means of judging of the fertdlity of some soils, and the lair of the
