per acre in Morton County, N. Dak. The hours per acre of horse 

 labor in these two counties were 19.2 and 25.7, respectively. In the 

 winter-wheat areas a greater variation was found, man labor varying 

 from 7.3 hours per acre in Pawnee County, Kans., to 17.5 hours in 

 Jasper County, Mo., and horse labor from 19.7 to 39.5 hours, respec- 

 tively. When the total labor was divided as to land preparation and 

 seeding, and harvesting and marketing, it was found that m nearly 

 every case the bulk of total horse labor came in the fall and spring 

 when the land was prepared and the crop seeded. In the spring- 

 wheat areas there was usually little difference in man-hours as thus 

 divided. Generally any difference that occurred indicated that 

 more man labor was required in land preparation and seeding than 

 in harvesting and marketing. In the winter-wheat areas wider 

 variations occurred in the two divisions, and usually the man-hours 

 for harvesting and marketing were higher than for land preparation 

 and seeding.

VARIATION IN LABOR REQUIREMENTS. 



From Tables XIII and XIV it is apparent that there was a wide 

 variation among individual farms in the amount of labor devoted to 

 growing an acre of wheat. In these tables the farm records included 

 in Table XII were grouped according to total man hours per acre.
