For all farms about 60 per cent of the plowing was done in the spring 
and in each size group a greater acreage was plowed in the spring than 
in the fall. The areas differed considerably; however, in their prac- 
tice with regard to spring and fall plowing. The percentage of the 
plowing done in the spring on the farms visited in the different areas 
was as follows : 
Per cent. 
; ' Madison County, Ohio , 88 
Seneca County, Ohio , - - - - 67 
Madison County, Ind 74 
Montgomery County, Ind ..-.-. 72 
Livingston County, 111 - 23 
Knox County, 111 59 
The areas did not differ greatly in the percentage of the total plow- 
ing done with tractors. In all, 267 of the 286 men did some plowing 
in the spring and 225 did some fall plowing. 
Spring, plowing. — The number of men on farms of different sizes 
who did all the spring plowing with tractors, those who used both
