half as many men reported the use of four horses as of three, but on 
the average the fourth horse increased the ground covered per day 
by less than one-tenth of an acre. Evidently the use of the fourth 
horse on this machine is not justified, excepting under unfavorable 
conditions.

SHOCKING CORN AFTER CORN BINDER. 
The average performance of 2. 3. and 4 man crews in shocking 
corn after the corn binder is shown in Table XVI. The most common 
crew used in this work, two men, covers about three-fourths of an 
acre more per day per man than do the 3-man crews, and 1.2 acres more 
per man than do the 4-man crews. However, on the average, the 2-man 
crews lack about one acre per day of setting up as much corn as a 
corn binder drawn by three or four horses cuts. The 3-man crew 
shocks on the average just as fast as the corn binder cuts the corn, 
while the 4-man crew can shock three-fourths of an acre more per 
day than is cut bv the binder.

One man with a corn binder drawn by three horses, and three men 
to shock the corn after the binder, cut and shock, on an average, 7.7 
acres per day. or about 1.9 acres per man. while one man by hand cuts 
and shocks on an average 1.28 acres per day. Thus the corn binder 
and three horses increases the efficiency of man labor for this opera- 
tion by nearly 50 per cent. If a two-man crew is used for shocking 
after the binder, and they cover 7 acres per day, the efficiency of each
