WINTER WHEAT IN THE GREAT PLAINS AREA. 
As given in Table III, the average farm price of wheat on Decem- 
ber 1 for the 10 years preceding 1915 has been, in round numbers, 
80 cents per bushel. It costs about 10 cents per bushel to take the 
grain from the shock, thrash it, and put it in the granary on the 
farm. This cost per bushel does not vary greatly with the yield and 
is therefore a fixed price per bushel instead of a fixed price per acre, 
as is the case with the other costs of production. The relative profits 
of producing winter wheat under the different methods can therefore 
best be determined by finding the difference between the fixed cost 
per acre and the value per acre of the grain at the point where the 
fixed cost per acre ends, which, as before stated, is when the grain is 
in the shock. Knowing that the average farm value of winter wheat 
in the granary is 80 cents per bushel and that it costs 10 cents per 
bushel to take it from the shock, thrash it, and put it in the granary, 
it is obvious that it would be worth 70 cents per bushel in the shock. 
This valuation of 70 cents per bushel has therefore been used as a 
basis for calculating the relative crop values, costs, and profits per 
acre of the various methods under trial.
