12 IOWA ACADEMY OF SCIENCE 



found today, proudlj^ acknowledge their indebtedness to him as teacher and 

 friend. 



Professor Calvin was a naturalist in the broad sense of that word. He loved 

 Nature, was in profound sympathy with all her phases, moods and movements; 

 he was a botanist, a zoologist, a geologist, and though more immediately con- 

 cerned at last with the history of the planet especially in recent phases, yet 

 in his deepest sympathy he was a student of life and her ways, and he turned 

 the pages of geologic record only the better to watch the drama, to measure the 

 stately progress of earth's living forms; he stood in reverence in the presence 

 of the ages and appreciated the sublimity of their mighty message. 



The members of this Academy recognize thus a life of supreme service to 

 the state, to education and to the cause of science in the world; they revere 

 the memory of Samuel Calvin and find in his example the purest inspiration 

 for future effort and devotion.
