HOW TO OBTAIN A LAKGE YIELD OF COKN. 223 



results that would probably be derived in a majority 

 of instances from pursuing a system of best methods. 

 But let us now compute the cost per bushel of this 

 crop. The yield would probably be one hundred and 

 fifty bushels per acre, as estimated. It might be 

 more, it might be less. To meet varying possibilities, 

 we will take several estimates, viz. : one hundred and 

 twenty-five bushels, one hundred and fifty bushels, 

 and one hundred and sixty-five bushels. The product 

 of stalks for these yields would be from five tons up- 

 ward. Taking the lowest rate, it would be five tons. 

 The amount assumed as the expense of the crop, fifty 

 dollars, is probably what it would be on an average. 

 We should then have the following result : 



Cost of crop $50 00 



Deduct 5 tons of stalks (at $6 per ton) 30 00 



$20 00 



This would make the cost of production, omitting 

 fractions : 



For a yield of 125 bushels, equal to 16c. per bushel. 



For a yield of 150 bushels, = 13c. per bushel. 



For a yield of 165 bushels, = 12c. per bushel. 



There may be those who will differ in opinion as 

 to this estimate. One will perhaps say that the quan- 

 tity of manure is not sufficient to account for such a 

 product ; another, that the planting is too close to 

 give such a yield of grain, etc. But certainly a 

 method, comprising half a score of different processes 

 and conditions, cannot fairly be judged by any one 

 of them considered separately. The yield is not the
