determined for any width and practical unit of horsepower.

The data for setting up grain in shocks after the gram binder are 
given hi Table XXXIY hi terms of one man according to the yield 
per acre. Through inadvertence the inquiry did not specify the 
kind of grain affected, so that the data of the table must be taken as a 
composite for oats, barley, and wheat, and is probably most accurate 
if the crop is assumed to be oats.

The averages for crew work in stacking grain from the shock are 
arranged in Table XXXV by crews most frequently used. In gen- 
eral, the daily duty per man is from 2.75 to 3.5 acres in stacking in 
the field, and from 2.5 to 3 acres when hauling to the barn. From the 
table of adjusted acreages in columns 5 and 8 the daily duty of any 
crew in work of this character can be approximated. In those regions 
where stacking grain is practiced, crews of more than four men are 
not common.
