THE QUESTION OF FATIGUE FROM THE ECONOMIC STANDPOINT. 323 



the efficient management and organisation of factory and office, 

 account must be taken of the human element just as much as of the 

 material and the machine. 



2nd. The importance of the rest-pause. A break in the work 

 would seem to shed its influence all round ; it causes a bracing excite- 

 ment that avoids accidents beforehand and brings on after it a new lease 

 of working capacity. More important than the length of working 

 day seems the length of spell : the splitting up, the breaking up of con- 

 tinuous periods of work. 



3rd. The importance of the nature of the work in modifying the 

 onset of fatigue. In uniform repetition work causing ' subjective ' 

 feelings of monotony ' objective ' fatigue seems far less effective than 

 in the nerve-taxing work of attending to a loom or of labelling and 

 soldering accurately in place. 



4th and finally. The importance of taking account of and studying 

 fatigue, and of adapting accordingly the hours of labour in each kind 

 of work.
