 The oat does best in moist and relatively cool weather. 



It is not to be supposed that it is possible for a man 

 to control the temperature of the soil to the degree that 

 he can bring about climatic conditions for growing a 

 crop, but by the proper conservation of moisture and 

 cultivation of the soil it can be made warm in the spring 



Ground in this condition becomes too hot in the summer for the suc- 

 cessful development of nitrates for growing corn. This soil, a silt loam, 

 requires very careful handling to prevent its powdering. 



when it otherwise would be cool, and cool in the summer 

 when it otherwise would be hot. To this extent the 

 temperature of the ground can be controlled. This 

 aids very materially in the growing of crops. The 

 means for bringing this about center around the amount 

 of moisture in the ground and the rapidity with which it
