NOTES 125 



And so the tests and personal letters continue to 

 encourage the instructor and open up many a vista of 

 unexpected applications or suggested truths. 



The variety of questions show the great need of the 

 study even among those favored with high scholarship 

 as well as among those trained in the thorough but 

 slower school of experience. 



When many facts of everyday life, of common ob- 

 servation, are seen to be caused by the growth of omni- 

 present, invisible plants put into the world as benef- 

 icent agents, all life becomes more interesting. Such 

 study should lead away from foolish or ungrounded 

 fear. It should lead to thought and wise action, that 

 the danger spots be prevented or removed; that each 

 do all in his power to protect not only himself but his 

 neighbor. 



How strongly it emphasizes the truth from the great 

 poet-philosopher, John Milton: 



" Not to know at large 

 Of things remote from use, 

 But to know that which 

 Before us lies in daily life 

 Is tne prime wisdom."
