FARM MANAGEMENT IN CLINTON COUNTY, INDIANA. 
49 
In Tables 40 to 42 no attempt was made to eliminate the influence 
of any of the other factors; while in Tables 43 to 47 the influence 
of each of the two other factors (of the three factors) have been 
largely eliminated. 
In most of the years the farm income was affected more by the 
acres per farm than by crop yields per acre or by livestock receipts 
per animal unit, farm income being somewhat of a size resultant. 
Labor income and percentage return on capital for most of the years 
were affected more by livestock receipts per animal than by either 
acres in farm or crop yields per acre. The family living from the 
farm for most of the years was affected more by the acres in farm 
than by either of the other two factors. 2 
On farms, regardless of size, the importance of crop yields per 
acre and of livestock receipts per animal unit as factors of successful 
farming can hardly be overemphasized. To bring out the contrast 
between farms below the average in both of these factors with those 
above the average in both Table 48 was constructed. 
Table 48. — Relation of farm income, labor income, -per cent return on capital, and 
family living from the farm, to farms below and above the average in both crop 
yields per acre and livestock receipts per animal unit.
