COST OF PRODUCING WHEAT.

results in material benefit to the crops which follow. From each 
farmer an estimate was obtained relative to the amount of clover 
seed used and the time required to sow this seed on the average 
amount of new seeding plowed under each year; also the crops 
following on this land were noted. With these data available a 
charge for the value of the clover seed used and the time required 
to sow it was computed, which amounted to $2.80 per acre. This 
cost was prorated to the crops receiving benefit. In the case of 
wheat this charge amounted to $0.33 per acre.

COMMERCIAL FERTILIZER. 
Commercial fertilizer was not used in any of the areas visited 
except Missouri, and in this State to no appreciable extent except 
in Jasper County. In this county 97 per cent of the men interviewed 
used commercial fertilizer on their entire wheat acreage, and 3 per 
cent used no fertilizer on this crop. The quantity applied averaged 
100 pounds per acre and the average cost was $42 per ton. 
In St. Charles and Saline Counties commercial fertilizer on wheat 
was not reported except on one farm in each county, where a very 
small acreage was fertilized, more as an experiment than as a regular 
practice. 
GRASSHOPPER CONTROL. 
In Ford County, Kans., much wheat was destroyed by grasshop- 
pers. To control these pests a mixture in the proportion of about 
20 pounds^ of bran, 1 pound of arsenic or Paris green, § gallon of
