A sample of fine-grained soil, on which it was proposed to plant 

 potatoes, was collected from the Hogsback Plateau, near Alice. The farm. 

 lies at an altitude of about 4,400 feet above sea-level. The surface soil 

 at the locality where the sample was collected is red and loamy; the sub- 

 soil is also red, but more clayey. The farm has a local reputation on ac- 

 count of its good forage and potato crops, but, in order to produce these, 

 a plentiful supply of manure is invariably found requisite: farmyard 

 manure is practically the sole fertiliser employed in the district.

This analysis clearly shows the reason why thorough manuring is so 

 necessary; lime and potash are both deficient, while phosphates are just 

 above the border line of poverty.

The Taungs District, which is represented by the above samples, is 

 situated at the northern extremity of the Campbell Hand, and therefore 

 near the region of the crystalline and siliceous limestones which charac- 

 terise that formation. One may accordingly expect to find a good pro- 

 portion of lime in these soils, but such an anticipation is not borne out 

 by actual results. The lime formation extends only over the Great Kaap 

 Plateau, and practically terminates at its edge, with the Rand, below 

 which, to the south-east, along the Harts River banks, are comparatively 

 poor Dwyka shales the grey and olive shales of Stow. The Taungs area
