neighbouring divisions of George, Knysna, and Uniondale, a clear evi- 

 dence that the soil can do with less nitrogen than, say, the Knysna soils 

 provide, if only the deficiencies in other respects be made up. A remark 

 of Prof. Hilgard may here be quoted as bearing directly on this point; 

 he says : * (and the italics are in the original) : " In general, we find that 

 lower percentages of potash, phosphoric acid, and nitrogen are adequate, 

 when a large proportion of lime carbonate is present." 



The stiff red clay about the town of Oudtshoorn has potash as its dis- 

 tinguishing characteristic : possibly the virtue of this clay lies herein, that 

 on mixture with surface soils already containing lime, and perhaps phos- 

 phates, in adequate amount the addition of potash fulfils the one need. 

 Samples 7 and 9, which contain good proportions of all the elements of 

 fertility, exemplify the causes of productiveness in the soils of this 

 division. 



The soils taken in the north-western part of the division are appa- 

 rently less fertile, lying, as they do, under the shadow of the great saaid- 

 stone range of the Zwartbergs, and in respect of both lime and phosphoric 

 oxide they show a diminution; but on approaching the Zwartberg Pass, 

 near which, it must be remembered, the limestone caves of the Cango dis- 

 trict are situated, the amount of lime in the soil naturally increases enor- 

 mously. 



On the whole it may be said that the soils of the Oudtshoorn Divi- 

 sion show good quantities of lime and nitrogen, and are also satisfactory 

 as regards potash and phosphates.
