TABLE No. 3 

 U. S. Department of 



Agriculture Reports : Presumably as used 



(Average yield same year) in the Bulletin : 



Wheat yield 12.5 bu. 18.9 bu. 



Corn yield 23.9 bu. 48.3 bu. 



Oats yield 24.4 bu. 40.3 bu.

From which it will be observed that in the problem, 

 as shown by the bulletin, the yield of wheat is 50 per 

 cent, above normal average ; yield of corn 100 per cent, 

 above the normal average ; and oats 66 per cent, above 

 the normal average. Again, the amount of the essen- 

 tial food elements taken from the soil by these crops 

 was not taken into consideration. Three of these ele- 

 ments potash, nitrogen and phosphorus are staple 

 commercial commodities, and at pre-war prices, the 

 amount taken from the soil by each bushel of grain, 

 as shown by Table No. 4, is as follows :
