36 Economic Cycles: Their Law and Cause 



According to the Yearbook of the Department of 

 Agriculture for 1912, we find the acreage and value of 

 the leading Illinois crops as they are given in the 

 subjoined Table: 



ACREAGE AND VALUE OF CROPS IN ILLINOIS, 1912 



Crop Acreage Value of Crop 



(1) Corn 10,658,000 $174,791,000 



(2) Oats 4,220,000 54,818,000 



(3) Hay 2,512,000 41,152,000 



(4) Wheat 1,183,000 8,641,000 



(5) Potatoes 137,000 8,302,000 



(6) Barley 57,000 952,000 



(7) Rye 48,000 538,000 



(8) Buckwheat 4,000 70,000 



(9) Tobacco 900 62,000 



It is clear, from this Table, that five crops corn, oats, 

 hay, wheat, and potatoes make up the bulk of the 

 crops of Illinois, and one could not go far wrong if he 

 based his generalizations as to the conditions of agricul- 

 ture in the state upon these five crops. But for the 

 purposes we have in view, in this and other chapters, it 

 is not possible to utilize the statistics of wheat produc- 

 tion because both spring and winter wheat are grown in 

 the state, and the statistics of their relative yield and 

 price are not given in the published material for the 

 long record covered in our investigation. Accordingly, 

 the crops that have been actually used in our inquiry 

 are corn, oats, hay, and potatoes. These crops total 

 93.13 per cent, of the crop acreage and 96.45 per cent, of 

 the crop value as these quantities are given in the above 

 Table.
