The crews for the respective districts varied somewhat in size. 
Sixty-three per cent of the Kocky Ford growers did this work with a

plowed with one man and four horses. Fort Morgan reported 22 
crews with one man and three horses, 32 crews with one man and 
four horses, and 12 crews with one man and five horses. In the

crews of one man and three horses; 80 crews of one man and four

141 with 1-4 crews at an average cost of $3.30, and 45 with 1-5 crews 
at an average cost of $3.63.
