minimum* in respect of the need of all plant food in adequate proportion. 

 Although in the soils referred to, potash is present in satisfactory amount, 

 and phosphates in fair proportion, the percentage of lime is low, as in- 

 deed it is also in the other soil from this district; in such a case it is 

 scarcely reasonable to hope for good returns, however satisfactory the 

 *oil may prove in other respects.

The first of these two samples was a surface soil ; the second was taken 

 one foot below the surface : they were procured through the Conservator 

 of Forests, Umtata, and had been collected in the Amanzamyana Planta- 

 tion, about eight miles west of the village of Mount Frere, and adjoining 

 Zibokwana's location. They are representative of extensive tracts of 

 country in which the cereal crops usually grown do not thrive, whereas 

 arboriculture is fairly satisfactory. It is not surprising that shallow 

 rooted crops fail, for the soil is exceedingly deficient in both lime and 

 potash ; there is, however, a moderate store of phosphoric oxide available, 

 according to the analyses, which resulted as shown below :

These were three drift sands collected in the vicinity of Port Nolloth. 

 The first two were surface soils, taken, respectively, from the south and 

 from the north drift. The third was taken one foot below the surface. 

 Lime, as may be expected in this case, is plentiful, but in respect of other 

 mineral plant food the soils are poor.
