 the physiological aspect of the problem, to determine the maxi- 

 mum output possible without undue fatigue to the workman ; 

 although it is recognised that these have been unfortunately 

 inadequate for a complete solution. 



It is none the less true that the intelligent and tactful applica- 

 tion of the principle enunciated by Taylor will produce a remark-

 if the goodwill and co-operation of the workers can be assured
