for 2-man crews in oats yielding 45 bushels per acre or less gave 17.4 
acres per day ; 281 estimates of the same sized crew with a yield rang- 
ing from 46 to 55 bushels gave the same area, and 60 estimates with 
a yield over 55 bushels gave 17.2 acres per day. 
UNLOADING GRAIN. 
Portable elevators are in general use in this locality for unloading 
corn and oats into the crib and bin, and in order to make possible a 
comparison of the efficiency of this practice with that of unloading 
with a scoop shovel the farmers were asked to estimate the time 
required to unload ear corn and oats by the two methods. (See fig. 
9.) No attempt was made to differentiate between the elevators op- 
erated by gasoline engines and those where horses furnished the 
power.

Table XXIII shows that on the average the elevator saves about 
20 minutes in unloading a load of corn and 18 minutes in unload- 
ing a load of oats. This saving in time, and the release from 
the hard labor of scooping grain is worth considerable, especially 
to men who are husking corn by the bushel. The most frequent 
size of load of ear corn reported was 40 bushels. The most frequent 
size of load of oats was 100 bushels, but no load greater than 100 
bushels was reported. Ten minutes was given most often as the 
time necessary for unloading these loads with an elevator, while 
30 minutes was given most often as the time for unloading them 
with a scoop shovel. 
HAYING OPERATIONS. 
Hay is not as important on these farms as corn or oats, most of 
the farms having under 20 acres in this crop. This is reflected in 
the machinery used for harvesting hay, most of the mowers and 
rakes being of the smaller sizes, and a Comparatively small number 
of hay loaders being reported. Nearly all of the hay is either 
clover, timothy, or clover and timothy, very few men reporting 
alfalfa. A study of the reports showed that the kind of hay and 
variations in yield apparently have little effect on the efficiency of 
the machines and crews, and no attempt has been made to take
