The agricultural clay varies from 18 to 36 per cent, in the surface 

 soils while in the subsoils it may rise to over 50 per cent. It need 

 hardly be stated that such soils would require great skill and care if 

 subjected to irrigation and are better calculated to fight the drought 

 on their merits with the assistance of deep drains and thorough culti- 

 vation. The natural retentive power of these soils is very great. The 

 Nitrogen is above the normal in every case, the Phosphoric Acid is 

 also so high that the need of Phosphatic manures is not indicated. In 

 two cases there seems a low amount of available Potash while the re- 

 serve supply is undoubtedly low. A trial of Potash on these soils 

 should be made. The proportion of Carbonate of Lime is adequate, 

 although Lime should produce benefits as regards the tilth obtainable.
