No. 1 of the foregoing soils is undoubtedly brack or alkaline, and it is 

 significant that the alternative name of the farm Middelplaats, whence it 

 was taken,, is Brakfontein : the high proportion of chlorine in this sample 

 will be noticed. 



It is not at all surprising to find how poor in all inorganic plant food 

 the primary sandstone soils of this Division prove to be. In the tables of 

 analytical results illustration hereof is afforded by the soils from Dasje&- 

 fontein (No. 10), Klipheuvel (No .11), Dunghye Park (No. 16), Paardeberg 

 (Nos. 19 and 20), and Klein Wolvegat (No. 22). 



It will be seen that very many of the soils of this part of the Colony 

 are distinctly deficient in lime : the area in which they lie is almost en- 

 tirely hemmed in by sandstone. Further east, in the Bredasdorp Division, 

 and in the western portion of the Division of Swellendam the influence of 

 the sandstone ceases, and accordingly the soils in those parts contain more 

 lime.
