THE OUTLOOK IN CHEMISTRY IN THE 

 UNITED STATES 1 

 It is the highest privilege of the presi- 

 dent of the American Chemical Society to 

 express to you, citizens of Boston, the so- 

 ciety's deep appreciation of your interest 

 in our science and of your courtesy in pro- 

 viding entertainment for our numerous 

 membership. In token of the reality of this 

 appreciation, no less than in recognition of 

 the honor bestowed upon me by you, my 

 fellow members in the society, it is my 

 pleasant duty to address you on some sub- 

 ject which might interest you as an impor- 

 tant phase of chemistry or which might 

 bring home to you as thoughtful citizens of 

 this great country of ours some of the im- 

 portant functions which our science may 

 be expected to fulfil in the life of the na- 

 tion. It is the president's happy privilege 

 also to select his own subject. In normal 

 times, I confess, I should have enjoyed the 

 pleasure the scientific man finds in riding 

 his own hobby before a large and friendly 

 public and I should have been tempted to 

 try to present to you some phase of those 

 wonderfully intricate worlds of atoms and 

 molecules and of the forces controlling 

 them, on which the peculiar power of our 

 science rests. But the spirit of complete 

 preoccupation in the great test to which our 

 country is being put, which I know per- 

 vades the minds and souls of all of you, has 

 led me rather to the choice of a subject of 

 more immediate relation to our present 

 situation. I have thought j'ou might be in- 

 terested in a discussion of the outlook in
