The table shows that in the work of producing each 

 of the crops considered, excepting only the cotton crop, 

 there has been an absolute displacement of man labor. 

 Disregarding the cotton crop, the absolute displacement 

 in the work of producing the other eight crops is 42.5 

 per cent. If cotton be included in the summary and 

 allowance be made for the additional labor employed 

 in the production of that crop, the absolute displace- 

 ment becomes 30.9 per cent.

Crop reports for the desired years could not be found in every case. 

 When the difference between the year reported upon by the investiga- 

 tions of the Department of Labor and the nearest year for which a 

 crop report could be had was greater than one year a later crop report 

 was preferred as yielding a displacement of labor too low rather than 

 too high.
