He has also left a permanent impress on geological nomenclature by 

 naming the Buchanan gravels, Independence shale, the Platteville, the 

 Delaware, and Hopkinton stages, tlie Decorah, Brainerd, and Clermont 

 shales, and the Elgin Shaly and Fort Atkinson limestones. 



Professor Calvin was especially strong in held work, and in this he 

 impressed every one who had the privilege of working with him by his 

 keenness of observation, his accuracy of correlation, and that unbounded 

 enthusiasm which remained unchecked to the very end of his life. 



As a teacher and a man he had few equals. Thirty-seven years of his 

 life were devoted to the students of the IJniversit}^ and no one left his 

 class-room or laboratory without carrying away sometliing more than a 

 mere knowledge of the professor's pet subject, for Professor Calvin was a 

 character builder. Though he could be a stern master he was kindly and 

 sympathetic in his attitude toward those who were associated with him in 

 any capacity, and his kindly helpfulness will long be remembered by those 

 who knew him best. He was impatient only at deception and superficial 

 assumption, and his love of truth and genuineness was ecpuiUed only l)y 

 that modest manhood which was at once the marvel and the model of his 

 students and associates. 



The influence of Professor Calvin's life may well be summarized in the 

 words of his old-time friend and associate. Prof. Thomas H. ^[acbride, 

 who, on the occasion of the thirtieth anniversary of Professor Calvin's 

 service in the University, wrote: "He was a teacher, and thousands of 

 pupils in all parts of the country owe to him the impulse of their intel- 

 lectual life ; he has been an organizer, and the work of natural science in 

 the University today is his ; he has been a man of science and the learning 

 of his time acknowledges on every hand its measure of obligation,"
