 table the daily duty of grain-harvesting equipment can be readily 

 determined for any width and practical unit of horsepower.

The data for setting up grain in shocks after the grain binder are 

 given in Table XXXIV in 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.
