208 INDIAN CORN. 



Previous expense $19 00 



To which add: 



Manure. ...... .... . $16 00 



Subsoiling 3 00 



Extra harrowing. 1 00 



Increased expenses of harvesting 50 



Total expense of crop .- .'. . $39 50 



Taking the yield of this crop at an average proba- 

 bility, it could scarcely be less than seventy-five or 

 eighty bushels. But calling it seventy bushels, this 

 would give two and four-fifth tons of stover, worth 

 sixteen dollars and eighty cents. 



From the above expense is to be deducted, not 

 merely the value of the stalks, but also one-half the 

 outlay for manure and for subsoiling, as the effect of 

 these is not limited to a single season, but extends to 

 successive crops. The net result, therefore, of this 

 crop will be as follows : 



Total expense $39 50 



From which deduct half the cost of manure and 



sub-soiling 9 50 



$30 00 

 From this deduct value of stalks 16 80 



Cost of TO bushels of grain $13 20 



which makes the cost per bushel about nineteen 

 cents. 



JSTow, on comparing the results of these three crops 

 from the same acre, we find that by increasing the 

 expense of cultivation, the cost per bushel is reduced 

 successively from fifty-six cents to thirty-nine cents and 

 nineteen cents. This reasoning is of course theoreti-
