THE EXPANDING RELATIONS OF 

 CHEMISTRY IN AMERICA i 



After a year of such strenuous service 

 as characterized that through which we 

 have just passed, it is well that we are again 

 assembled for report on the work of our 

 laboratories and for helpful conference 

 concerning future growth and broader 

 service. A large part of the past year's 

 work has, through the suddenness of the 

 call, been necessarily individualistic; the 

 assemblage of this week furnishes the means 

 for planning more coordinated effort for 

 mutual counsel and for deepening that 

 spirit of cooperation which is so essential 

 if we are to worthily meet our full respon- 

 sibilities. 



It is again incumbent upon me to address 

 you. In seeking a subject I have put aside 

 the temptation to lay before you statistics 

 illustrative of marvelous growth during the 

 past year, and, in spite of our belief in spe- 

 cialization, it has not seemed suitable to 

 select any one line of development for tra- 

 cing in thorough detail. This period is still 

 too formative and the demands upon you 

 too many-sided for such restricted discus- 

 sion. I have therefore selected the broader 

 topic "The Expanding Relations of Chem- 

 istry in America," using the present par- 

 ticiple advisedly as indicative of growth 

 and as mandatory of greater effort if the 

 widening circles of chemical influence are 

 to reach the broad shores of full-fledged 

 accomplishment.
