MACHINERY AND LABOR 

 SAVING OF LABOR 



The quantity of labor which, by the use of machine 

 power, is saved for other uses, may be determined, in 

 the case of any particular crop, by finding the difference 

 between the number of days-work requisite for pro- 

 ducing it by hand and by machine methods. In the 

 following table there is shown the quantity of man- 

 labor requisite for producing the nine principal farm 

 crops by hand and by machine methods ; the quantity 

 of labor saved in each case by the use of machinery ; 

 and the per cent which the quantity of saved labor is 

 of the quantity requisite for producing the several crops 

 by hand method.
