bushels, and $6,881,900,000, respectively. The acreage, pro- 

 duction, and value of each of these crops in 1917 are shown 

 in Table I. 



Table I. Acreage, production, and value of each of the important 

 grain crops in the United States in 1917, and the total for all grain 

 crops. 



The improved farm land in the United States in 1909 

 was 477,424,000 acres. Of this total, 40.09 per cent was in 

 grain crops, as follows: Corn, 20.61 per cent; wheat, 9.28 

 per cent; oats, 7.36 per cent; barley, 1.61 per cent; rye, 0.46 

 per cent; flax, 0.44 per cent; buckwheat, 0.18 per cent; and 

 rice, 0.15 per cent. The acreage of improved farm land 

 in 1917 is not definitely known, but it was of course larger 

 than in 1909. The acreage of wheat in 1917 was abnormally 

 low on account of losses from winterkilling. Otherwise,
