of pullers or lifters were used in these districts. One, known as the 

 "crotch" or "straddle puller," has two shafts, with special points 

 which pass on either side of the row. The other type is known as the 

 "side puller" and has only one shaft with a single point. In both 

 cases only one row is pulled at a time (fig. 21). Lifting or pulling 

 coincides with the harvesting dates (Table XXI). During the two 

 years of this investigation (1914 and 1915) harvesting in the Rocky 

 Ford district ran from September 1 to December 15, at Fort Morgan 

 from September 20 to November 20, and at Greeley from August 25 

 to November 26. Occasionally unfavorable weather occurs during 

 the harvest period and this has a tendency to delay or prevent 

 harvesting.

There was considerable difference in each area in the number of 

 horses used to do the lifting. In the Rocky Ford area on 52 farms 

 a crew of one man and three horses did the plowing out; on 46 farms 

 one, man and four horses; and on 6 farms one man and two horses. 

 In the Fort Morgan district the farms reporting were about equally
