222 EVOLUTION 



and cram; thereafter, with the unison of 

 all three will come education indeed; artistic, 

 scientific and practical; heart, head, and 

 hand; and each calling out the others to 

 fuller expression and development. 



Concretely, how can this dream of in- 

 dividual development so important for the 

 progress of science, the reading of evolution, 

 be actually applied and brought about? So 

 far as the sciences are concerned — and these 

 are commonly esteemed the most difficult— 

 the principles of its apphcations are clear. 

 While the services of each science to practical 

 life are constantly insisted on, and in no 

 danger of being overlooked, we far more 

 often and readily forget the rise of each 

 science from practical life. But the historic 

 beginnings of geometry with measurement 

 are again in progress in the schools. Those 

 of astronomy with navigation have long been 

 well taught to the sailor youth, and now the 

 boy scout is learning, like his pastoral an- 

 cestors, to find his time by the sun, his way 

 by the stars. Nor is this a matter of ele- 

 mentary education merely; here lies the 

 main progress of research also, that higher 

 education of the individual and the race 

 together. Thus the problems of daily life, 

 the emergencies of practice, called out the 

 highest powers and achievements, from Ar- 

 chimedes of old to Kelvin yesterday.
