while in the Rocky Ford region it was about S2.50. A days work 
with a cultivator varied on the average from S.4 acres in the Rocky 
Ford district to S.8 acres in the Greeley district.

Eighty-eight per cent of the growers reported on fiUTowing. or 
preparation for irrigation. In the Rocky Ford district the operators 
furrowed approximately three times, one furrowing coming early. 
immediately after planting. There was an intermediate furrowing 
and a third after cultivation had ceased. Cultivating the land after 
•an irrigation necessitates a repetition of the furrowing. In northern 
Colorado furrowing was done almost entirely after the last cultiva- 
tion. This operation required, in general, a crew of one man and 
two horses. The variation in cost in 1914 and 1915 shown in Table 
XIX is mainly due to variation in the number of times the fields 
were furrowed. A day's work furrowing ranged from 9.4 acres to 
10 acres as averages for these groups.
