IO. & 
Nore.—All farms on which tractors were used were excluded from these tabulations. The above figures 
wers obtained by dividing the hours spent on each operation by the number of acres for which the operation 
was performed. As not all these operations were performed on all farms, the sum of the hours spent on each 
operation may be greater than the average hours of horse labor required in the production of an acre of 
sugar beets shown elsewhere in this report.
