FACTORS IN WHEAT PRODUCTION in 



To hire the threshing done is the economical plan. 

 It is prevalent in all sections except on the 

 ' bonanza farms," found in some parts of North 

 Dakota, California, Washington, and Canada. For 

 wheat farms of 



500 acres or 

 more, the 

 grower generally 

 provides his own 

 thresher. 



The Power 

 used in Wheat 

 Raising. 

 Horses consti- 

 tute the chief 

 power used in 

 the world's pro- 

 duction of 

 wheat. How- 

 ever, in the more progressive countries, and partic- 

 ularly in sections where large fields predominate, 

 much of the work which was formerly done only by 

 horses, is now done by steam and gas engines. 

 Tractors are used for plowing, seeding, harvesting, 

 threshing, and even marketing. The cost of this 

 method is usually not much less per acre than that 

 of horse labor, but the daily capacity is much 

 greater. Since wheat needs prompt attention, this 

 is the great point in its favor. But even in such

 practice.
