DAYS' WORK NECESSARY TO PRODUCE 

 A. BY HAND METHODS 



. BY MACHINE METHODS 



The total amount of man-labor power saved by the use of machin- 

 ery in the production of these nine crops was 450,368,992 days' 

 work or 79 per cent of the amount of work which would have 

 been required to produce those same crops by the earlier hand meth- 

 ods. In other words, the quantity of labor now requisite for the pro- 

 duction of a given quantity of these nine crops is, on the average, 

 only 21 per cent, or a little over one fifth of the quantity which 

 would be requisite under the former hand methods of production. 1
