THE CEREALS IN AMERICA 



This diagram indicates that during the past decade the pro 

 duction of wheat has increased faster than population, while 

 average annual yields by decades based upon the estimates 

 of the United States Department of Agriculture indicate that 

 the production of wheat has not increased as rapidly as popula- 

 tion. (182) 



184. Center of Wheat Production. — ^While wheat is grown in 

 every State in the Union, the greater part is raised in the 

 Mississippi Valley. Ten States produced sixty-five per cent, 

 twenty States produced ninety per cent of all the wheat grown 

 in the United States in 1900. 



The center of wheat production in 1900 was about seventy 

 miles west of Des Moines, Iowa (N. Lat. 41° 39' 19" and W 

 Long. 94° 59' 23"). In fifty years this center has moved nort!, 

 about ninety-nine miles and west about 680 miles. 



185. Winter Wheat and Spring Wheat. — In 1902 about three 

 fifths of the wheat of the United States was sown in the fall. 

 The yield for winter wheat was 14.4 and for spring wheat 14.7 

 bushels per acre. 



Wisconsin, Iowa, Kansas, Nebraska, Idaho, Washington and 

 Oregon produce both winter and spring wheat. Minnesota, 

 North Dakota, South Dakota, Colorado, Utah, Montana, New 

 Mexico, Wyoming, Nevada, Arizona, Maine and Vermont raise 



spring wheat, while the 

 rest of the States raise 

 winter wheat. 



186. Production of 

 Flour. — There were about 

 490 million bushels of 

 wheat made into flour 

 in the United States 

 in 1900. A little more 

 than two-thirds of it was
