CHEMICAL CORN-GROWING. 93 



According to the report of the committee, the yield of this 

 field is at the rate of one hundred bushels per acre. Hence 

 we present the following account : — 



Total cost of crop per acre, $61 36 



Credit with 5 tons stover, at $8, 40 00 



Total cost of 100 bushels shelled corn, $21 36 



Cost per bushel, 21J- 



One strip of feleven rows of this field was left unmanured. 

 The yield on this portion was at the rate of 68| bushels per 

 acre, as below : — 



Merchantable corn, 68 bushels. 



Unsound corn, | bushel. 



Reasoning as with the fertilizer crop, Prof. Stockbridge 

 would say that the 5.2 cords of manure applied to the field 

 produced thirty-two bushels of corn, as this is the diflerence 

 between the yields of the manured and the unmanured por- 

 tions of the field. 



The question need not concern us, as farmers, whether the 

 fertilized crop is cheaper than the manured crop, or vice versa; 

 as farmers, we cannot obtain all the manure we would desire, 

 but we can obtain fertilizers in unlimited quantity. Can Ave 

 use these fertilizers to a profit, after we have used all the 

 manure that we have. Although I propose to compare the 

 items of expense of these two crops, I wish to discard the 

 notion that any attempt is being made to show one system 

 either superior or worse than the other.
