88 Minnesota Academy of Science 



As a broad student and scholar and as editor of the Ameri- 

 can Geologist, Prof. Winchell had an unusual opportunity to 

 build up a collection of geologic books and periodicals, which 

 was one of the most valuable private libraries in the country. 

 This priceless collection, which could not have been obtained 

 by purchase from dealers at any price, Prof. Winchell, with 

 characteristic generosity, gave to the University of Minnesota in 

 1911. 



As bearing on his contributions to science, there should be 

 mentioned also the contributions of the men who were trained 

 on the Geological Survey of Minnesota. These men, most of 

 them at an early age, were employed by Prof. Winchell, in the 

 Minnesota work and thus they received inspiration and guidance 

 from him. Of those who have had distinguished careers in 

 geologic work we may mention W. M. Harrington, Warren 

 Upham, M. Wadsworth, J. E. Todd, U. S. Grant, A. N. Win- 

 chell, E. O. Ulrich, H. V. Winchell, J. E. Spurr, A. H. Elft- 

 mann, H. V. Hoveland, and Charles Schuchert. Many of these 

 men are now the leading authorities in their particular fields. 



Great men may pass away, but their works are imperish- 

 able, and their influence is carried down the ages by those whom 

 they have instructed and inspired. Their contributions to knowl- 

 edge are our heritage and the heritage of countless generations 

 that are to come.
