246 THE WHEAT INDUSTRY 



of wheat in these states is from 10 to 18 per cent 

 higher than in the states which are west of the 

 Missouri River. The value of a marketing advan- 

 tage to an exporting region is here well illustrated. 



Because of keener demands for some of her other 

 products, this region has not in recent years been in- 

 creasing in wheat production. The new, cheap lands 

 of the West have increased the supply of wheat, and 

 other products have here become more profitable. 

 Since population is increasing rapidly and the new 

 lands in the United States available for wheat are 

 now largely under cultivation, this condition cannot 

 be permanent. Further development will center 

 about a higher yield per acre rather than more 

 acres, and in such a development this region gives 

 promise of playing an important part. 



The Southwest Central Plains Wheat Region. 

 Among the states west of the Mississippi River and 

 east of the Rocky Mountains marked differences in 

 conditions are found from North Dakota to Texas. 

 The transition, however, is a gradual one. In 

 general, the states south of the fortieth parallel 

 have sufficient similarity to be grouped into one 

 region. Of these states, the greatest wheat pro- 

 ducer is Kansas, which is followed by Missouri, 

 Oklahoma, Texas, Colorado, Arkansas, and New 

 Mexico in the order named. 



The climate here favors the production of winter 

 wheat. The summers are hot. Temperatures in
