SPRING WHEAT IN THE GREAT PLAINS AREA.

fixed cost per acre ends, which, as before stated, is when the 
grain is in the shock. Knowing that the average farm value of 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 these various methods. 
In conformity with the foregoing explanation, Table IV gives in 
detail the cost of producing wheat in the shock, expressed in dollars 
and cents, and in bushels per acre at 70 cents per bushel in the shock.

RESULTS AT THE SEVERAL STATIONS. 
Accompanying the presentation of the results for each station is a 
brief soil description, with particular reference to the depth of the 
soil and its water-holding capacity. Only such information is given 
as is necessary to understand fully the interpretation of the results. 
JUDITH BASIN FIELD STATION. 
The field station at Moccasin, Mont., in the Judith Basin, is located 
on a heavy clay soil of limestone origin. The soil is apparently very 
rich in available fertility. It is underlain, at a depth of approxi- 
mately 3 feet, by a limestone gravel that is closely cemented with 
lime materials. The gravel subsoil, which extends to a depth of 
about 30 feet, is practically free from soil. While it is so closely 
cemented that it does not unduly drain the soil, it is not of a character 
that allows the storage of available water or the development of 
roots within it. The presence of gravel in the surface soil does not
