, A DECADE OF AMERICAN MATHE- 

 MATICS 



The year just closing carries with it into 

 the past another calendar decade, and the 

 fact suggests that I take up with an audience 

 representing the mathematical section of the 

 American Association for the Advancement 

 of Science and the two other mathematical 

 societies meeting with it, a sketch of the 

 progress of our science in this country during 

 the decade. In doing this, I am led to reflect, 

 when I think of the struggle that has marked 

 the period, that though it is difficult to see ' 



how a thoughtful and disinterested person can 

 enthuse over international rivalries in terri- 

 tory, dominion, trade advantages or other de- 

 tails of national prestige which are pregnant 

 with dangers of destruction far beyond any 

 possible advantages gained, a desire for na- 

 tional preeminence in scientific attainment is 

 most wholesome and valuable. 



I wish I might, therefore, compare the 

 work of America during the decade with that 

 of other countries. But even if this were fair, 

 in view of the handicap the war has imposed 

 on other countries, it would inevitably entail a 

 sitting in judgment on questions of value over 

 a field so broad, with so large a body of work- 

 ers, that I have hesitated to assume the com- 

 petency or to appropriate the time requisite 

 to a proper performance of the task. 



Instead, I am restricting myself to a re- 

 view of some aspects of the work of this 

 country alone, seeking to find the directions 

 it has taken, to find some of the respects in 

 which it has been weak, and in which strong, 

 and to draw a few conclusions as to strength- 

 ening it in the future. 



As to an anlysis of the contributions made, 

 you will agree that since over 1,200 articles
