FARM MANAGEMENT IN CLINTON COUNTY, INDIANA. 43 
Price levels were the main reasons for the higher receipts and higher 
farm and labor incomes, etc., the later years as compared with the 
earlier years of the investigation. In 1919 the average prices received 
for each crop, for each livestock product, and for hogs were more than 
200 per cent of the first 4-year average prices, while those for live- 
stock, other than hogs, were each less than 200 per cent. 
In comparing the average prices of products for the last 4-year 
period with those of the first 4-year period, corn, wheat, rye, clover 
seed, potatoes, straw, wool, and hogs each sold for about twice as 
much per unit the last period as the first; oats, dairy products, and 
eggs each for about three-fourths more; cattle for hardly two-thirds 
more; hay and chickens each for about one-half more, while horses 
and colts sold for about the same prices both 4-year periods (fig. 13). 
Some farmers obtained higher prices for their products than others, 
but the prices obtained by fully 75 per cent of them were within a 
range of 10 per cent from the average of all farms, and those obtained 
by fully 50 per cent of the farmers within a range of 5 per cent from 
the average prices for all the farms. These variations were largely 
due to the quality of the products, the time of selling, or the bar- 
gaining abilities of the farmers. 
The prices received for products were an important factor in the 
returns to individual farmers; that is, if uniform selling prices had 
been applied to each farm, there would have been decided differences 
in the receipts, farm incomes, etc., of a number of farms, but there 
were about as many of the less successful farms which received above 
average prices as there were of the more successful. 
ACRES, CROP YIELDS PER ACRE, AND LIVESTOCK RECEIPTS PER 
ANIMAL UNIT IN RELATION TO FARM EARNINGS. 
In the choice of enterprises and of the combination of the factors of 
production, it must be borne in mind that two quality factors — crop 
yields per acre and livestock receipts per animal — have important 
bearings upon the farm profits. The multiplicity of factors contrib- 
uting to successfully conducted farm businesses render it difficult 
to so segregate any one factor from the others that the effect of the 
single factor upon the profits of the business can be measured with 
exactness. However, with such groupings of farms as in Tables 40 to 
47, the influence of the factors of size of farm, crop yields per acre, 
and receipts per animal unit upon the profits of the farm business, 
as well as the relative importance of each, may be approximated.
