COST OF PRODUCING WHEAT. 
27 
In the spring-wheat areas all but eight of the 159 farms were well 
represented in four groups, or in those classes having man labor 
requirements of from 4 to 12 hours per acre. In Grand Forks and 
Spink Counties, nearly all of the farms came within the two groups, 
'^4 to 6 " and ^' 6 to 8 " hours per acre. In Morton County the largest 
group of farms required from 8 to 10 hours of man labor per acre, and 
in both Minnesota areas the majority of all farms showed require- 
ments of from 6 to 10 hours per acre. Of the total wheat acreage 
grown on the spring-wheat farms more than one-third was grown on 
farms having man labor requirements of from 6 to 8 hours; also a 
large acreage was represented by each group of farms commencing 
with 4 to 6 hours per acre, and including the 10 to 12 hour group.
