isolated spots. Broadly speaking, the soil is classed as timber land and 

 plain land, the former having at some period been more or less thickly 

 covered with box trees. Sandy ridges with pine are of infrequent occur- 

 rence and are generally too high for irrigation unless by pumping. Although 

 analysis does not reveal any marked difference, the plain land is of a 

 more friable nature and easier worked, but it gives up its moisture too 

 quickly to allow of continuous successful irrigation. Whether this defect 

 will be remedied by subsoiling remains to be proved. Isolated experiments 

 have been made on small areas of both classes of soil, but the results so 

 far are not sufficiently definite to admit of any conclusive opinion. Sys- 

 tematic treatment in tins direction is being undertaken but the results must 

 be awaited with patience.
