ditions farther south, where the daily period of 

 sunshine is several hours less. Thus it will be 

 observed that climatic conditions favor good 

 yields of very high grade wheat, since sufficient 

 rainfall occurs in the early stages of growth, and 

 warm, bright, sunshiny weather prevails during 

 the later growth stages and through the harvest. 



The prairie soils of Canada have become widely 

 known because of their fertility. Generally they 

 are deep, dark colored, and mellow. They con- 

 tain, as a rule, large percentages of all the essential 

 constituents required for wheat, and are also 

 characterized by exceptionally high humus and 

 nitrogen contend This may be accounted for 

 by a rainfall sufficiently high for plant growth but 

 not high enough to cause heavy leaching. 



The Kinds of Wheat raised in Canada. - - Since 

 severe winters are prevalent over much of the 



Canadian wheat belt, spring wheat is the type 



most widely grown.,_ Hard spring wheats^ are 

 common in Manitoba, in the greater part of the 

 Saskatchewan, and in upper Alberta. Soft spring 

 wheats are grown in Quebec and New Brunswick. 

 Hard, winter wheat is rajsed in southern ^Alberta, 

 while soft winter wheats are grown in western 

 Ontario and British Columbia. Because of its 

 drought-resisting properties, some Durum wheat 

 is produced in southern Alberta and southwestern 

 Saskatchewan. Thus it will be observed that the
