ADDRESS OF THE PRESIDENT OF THE 



AMERICAN ASSOCIATION FOR THE 



ADVANCEMENT OF SCIENCE."- 



THE SCIENCE OF EDUCATION. 



The record of the year 1906 exhibits so 

 many kinds and degrees of progress; such 

 evidence of improvement in national and 

 international well-being; such a develop- 

 ment of the arts of peace in all lands ; such 

 exhibitions of zeal, individual and social, 

 in behalf of corporate and governmental 

 integrity; such abundant industrial and 

 commercial prosperity; and finally such a 

 universal tendency to promote education, 

 to advance science and to foster higher 

 standards of civilization— in short, the 

 year just past is so full of noble endeavor, 

 and endeavor crowned with success, that I 

 stand almost mute in the presence of what 

 ought to be said of the advancement of 

 science, as science grows from more to 

 more, and more and more is applied to the 

 myriad arts of life. 



I agree heartily with Huxley and others 

 that there is no valid distinction between 

 pure science and applied science. The final 

 test of the value of what is called science 

 is its applicability, and it is one of the sig- 

 nal triumphs of the last few years that 

 much of what was rated as 'pure science,' 

 and 'pure' because useless, has proved to 

 be invaluable either in widening the bound- 

 aries of scientific attainment, or in the de- 

 velopment of the useful arts. 



All genuine science should be both pure 

 and applied. In a word, let the purity and 

 the application be taken for granted; and
