SIZE OF FARM AND SIZE OF TRACTOR. 
The number of tractors of different sizes on the farms of different 
sizes (as measured by the number of crop acres) is shown in Table 8.

Seventy- five per cent of the farms with less than 160 crop acres 
were equipped with 2-plow tractors, and 53 per cent of those with 160 
or more crop acres were equipped with this size of machine. 
WORKSTOCK ON FARMS OF DIFFERENT SIZES. 
The average number of workstock, the number of days of horse 
labor per farm, and the number of days' work per head on the farms 
of different sizes during the year of the investigation are shown in 
Table 9. The number of days' work per head was obtained by divid- 
ing the number of days' work on the farm by the number of works tock 
kept. Each farmer gave the number of hours which are considered 
a full day's work on his farm both for the works tock and for the 
tractor, and the average is practically 10 hours for each. 
The number of workstock varied considerably on farms of the same 
size. Likewise the number of days of horse labor per farm varied 
considerably, depending upon the acreages and yields of the different 
crops, upon the practices followed in preparing the seed bed, planting,
