 Indeed, on some of the richer soils in the more humid 

 sections it may, under good management, be practically 

 dispensed with.

 subsequently these will have to be maintained in the soil 

 by the return of manure or fertilizers or by plowing 

 under legume crops. 



There is little doubt but that as time goes on modifi- 

 cations of the present system will be found that will suit 

 many conditions in the Canadian West better than the 

 present general practice. Sorghums are more or less 

 completely replacing the fallow in the drier States and 

 corn in the northern States. Even in parts of Mani- 

 toba corn is now being used as a substitute for the fal-

 and Saskatchewan this crop offers considerable promise 

 for the future. The use of such a hoed crop carries with
