228 EVOLUTION 



results and impulses: here with biometrician 

 disciples, there with no less active Mendelian 

 antagonists ! 



Yet, as we have seen, it is not enough to 

 be students even of Man and Nature; we 

 must also take our part in the world of action, 

 if we would understand the action of life. 

 The scientist has affirmed this intensely in 

 his insistence on field work, on museum 

 work, on laboratory work: but still too 

 narrowly; even with zoological stations and 

 experimental institutes thrown in. Here no 

 preparation can be too full, too varied in its 

 practicality. 



Explore our region here, and any other 

 you may have the good fortune to reach, 

 fully, thoroughly, repeatedly, from hill- 

 top to sea-bottom and back again. Realize 

 your environment, your region through 

 activity also: and this not only as an ex- 

 cursion-field, a playing-field, from ski to 

 dive, it may be as hunting-field in moderate 

 measure, but as work-field also, and above 

 all. Go down into mine and quarry; get 

 some turn at hewing coal, at dressing stone. 

 The anvil, the joiner's shop, the carver's or 

 other studio are all excellent; already com- 

 ing into use for afternoons at any rate of 

 school winters in town: in summers be out 

 in Nature; see and touch Nature alive.
