more valuable when they are made in the course of 

 the regular work. 



6. To teach the value of an instant's relaxation at 

 certain points in a series of movements. This does 

 not need so much emphasis because the body will 

 force it upon the attention. If the value of the econ- 

 omy of strength was realized more fully, moments of 

 relaxation would be inserted and the work improved 

 by doing so, and many an unnecessary breakdown be 

 prevented. 



In a task that is requiring concentrated effort, or 

 a fixed position, the strain is great. A person spading 

 steadily, without any moment of relaxation, will soon 

 tire, but there are two well-marked places where they 

 can rest for a fraction of a second, and should do so 

 to avoid rapid exhaustion just after pushing the 

 spade into the ground, and just after the completed 

 operation. Both rests come while standing upright. 

 With this knowledge applied, one can spade very much 

 longer without tiring. 



7. To teach the individual speed limit. This can 

 be well taught in spading, and is a valuable thing to 

 learn, for it has a wide application. Each individual 

 worker has a certain speed of working at which he 

 will do his very best, and if he works either faster or 

 slower the result will not be as good. To work too 

 slow results in lack of attention. To work too fast 

 results in slipshod work. Every individual has a dif- 

 ferent speed limit for good continuous work. 



Roughly speaking, if they double this speed they
