growth of a more mature plant. These soils are markedly deficient in 

 organic matter and in i^hosphoric acid. On them the growing of wheat 

 is treated as a catch crop, and often the ultimate aim is just grass 

 improvement. The land is cleared, ploughed, left fallow till seed time, 

 and sown to wheat or oats. Perhaps two crops are obtained in this way 

 before the paddock is allowed to rest in grass for an indefinite period. 



The sandy soils referred to as occurring adjacent to sand-hills do 

 not puddle down like the silty soils, but in a wet year may become water-

logged because of the impervious nature of the clay subsoil. In a dry 

 year the crops " hang out " over long stretches. The rich sand hum- 

 mocks are easily worked, and are capable of growing splendid crops. 



The heavy clay soils are somewhat difiicult to manage until they 

 become levelled with cultivation. They will stand frequent cropping, 

 and do not puddle as does the silty type. Under pres^mt methods soils 

 of the heavy class, and those related to them, are apt to become very 

 foul with wild oats and thistles.
