ANNIVEBSABY ADDBESS, IOWA ACADEMY 

 OF SCIENCE^ 



There is an old and familiar phrase 

 which reads: "To all to whom these pres- 

 ents may come, greeting." I remember 

 how in youthful days this phrase struck 

 me as of peculiar mold and how, without 

 perhaps realizing its antiquity or history, 

 I puzzled as to its full significance and the 

 conditions which, in some distant era, must 

 have given it birth. We need not now at- 

 tempt to trace its lineage or discover how 

 ancient ambassadors or messengers may 

 have used it in their visits to friend or foe, 

 but I like to fancy for the moment that I 

 am commissioned to bring to you on this 

 anniversary occasion the greetings and con- 

 gratulations of the world of science. Cer- 

 tain I am that such greetings and congrat- 

 ulations must extend from organized sci- 

 ence in general and especially from all 

 societies of similar scope. 



Science is essentially mutualistic and the 

 success of one organization is the gratifica- 

 tion of all — the triumphs and discoveries of 

 one are shared with the many and the feel- 

 ing of pride in the progress of the one may 

 be shared without loss by sister organiza- 

 tions. As the discovery made in one 

 branch of science may be the necessary 

 foundation for the solution of some prob- 

 lem in another, so the contribution from 

 one society may be the stepping stone to 

 advancement in another. It is all hail 

 then, greetings and felicitation and God- 

 speed in the accomplishments of your fu- 

 ture destiny.
