FARM-MANAGEMENT SURVEY OF REPRESENTATIVE AREAS. 29 
The results are the same for each district studied. The machinery 
cost on the small farm of 40 acres or less is double that on those 
over 200. As the area increases up to 100 acres there 1s a marked 
‘decrease in the machinery cost, but above this area the gain in efli- 
ciency is small or entirely lacking. 
RELATION OF THE SIZE OF THE FARM TO THE CROP YIELDS. 
Climatic conditions have such marked influence on crop yields that 
records for one year are of little value as a measure of the yields 
in a given region. However, such records do permit a comparison 
of yields on farms of different sizes when conducted under the same 
system of management. 
It is generally beheved that the small farm is more efficient owing 
to better crops. This appears to be a mistaken theory. The figures 
given in Table XXIT show the average yields of corn, oats, and 
wheat on the large and small farms.

1 The yield of corn in Iowain 1910 was much below normal, owing to drought in early summer. 
In Indiana higher yields of both corn and oats were obtained on 
the larger farms. The difference is slight, yet 2.6 bushels of corn 
is worth considering. 
In Ulinois the highest yields of corn were secured on the smaller 
farms. On the other hand; the yields on larger farms, those ex- 
ceeding 320 acres in size, excelled both groups, ranging in size from 
81 to 320 acres. There were only 12 farms under 80 acres, too few 
from which to draw definite conclusions. 
In Iowa the larger farms consistently had the better yields. 
RELATION OF THE TYPE OF FARMING TO THE INCOME. 
All the farmers in the regions studied are following the same gen- 
eral expansive system of agriculture, developed on the basis of 
maximum product per man. Within this system two important
