Fig. 2. Chart showing the value per acre of 10 crops combined (corn, 

 wheat, oats, barley, rye, buckwheat, potatoes, hay, tobacco, and cotton), rep- 

 resenting about 90% of the total cultivated area of the United States. 



These figures present the gross income per acre of fields and 

 meadows, actually tilled that year, and show that even at present 

 prices this gross income is only about $16 an acre and that for more 

 than 25 years prior to 1904 it was usually below $12 an acre of fields 

 and meadows. These fields contained 47 acres per farm, or made 

 only 34% of the farm itself. The following table indicates the rel- 

 ative importance of the principal crops, and presents some figures 

 on the cost of production of farm crops in the United States, 1909.
