Stacking 
Eight men and 14 horses put up 30 acres (30 tons) per day. Yield, 1 ton per acre. Man-hours 2.66. team- 
hours 2.33 per ton. Labor cost, S0.99S per ton. 
Methods 30 and 31. 
Method 30 is givenin order to show the high cost due to poor method. 
The hay is raked the second day with side-delivery rake. The third 
day two sweep rakes bring it from the windrow and dump it close 
to the stack site. The fourth day it is picked up by two other sweep 
rakes and stacked. Thus every day there are four sweeps in use, 
two dumping near the next stack site, and two picking up the bunches 
brought up the day before. 
Method 31 is a rearrangement of method 30. The hay is delivered 
direct to stacker and not dumped on the ground. This reduces the 
crew from 9 men and 16 horses to 7 men and 12 horses, and lowers the 
cost 36 cents per ton.
