next eight years were spent alternately in studies at the univer- 

 sity and in school teaching, the schools taught being in Ann 

 Arbor, Grass Lake, Flint, Kalamazoo, Colon, and Port Huron, 

 Michigan. Previous to his graduation at the university, in 1866, 

 he had been two years the superintendent of public schools in 

 St. Clair, Mich. ; and next after graduation he was again super- 

 intendent of schools at Adrian in that state for two years, 1867- 

 69. He received from his Alma Mater the degree of master of 

 arts in 1867. 



During a year, in 1869-70, he was an assistant to Prof. Al- 

 exander Winchell on the Geological Survey of Michigan ; and 

 later in 1870 he visited and reported on the copper and silver 

 deposits of New Mexico. In 1871 he assisted Prof. J. S. New- 

 berry, the state geologist of Ohio, surveying and reporting on 

 twenty counties in the northwestern part of that state. 



In the summer of 1872, N. H. Winchell was invited by Presi- 

 dent Folwell, of the University of Minnesota, to take up the 

 work then recently ordered by the legislature for a survey of the 

 geology and natural history of this state, to be done under the 

 direction of the Board of Regents of the University. In this 

 work he continued twenty-eight years, until 1900 ; and during 

 the first seven years, until 1879, he performed also the full duties 

 of the university professorship of geology. Later he relin- 

 quished teaching, aside from occasional lectures, and gave all his 

 time to the diversified duties of the state survey and the curator- 

 ship of the university museum. 



In the summer of 1874 Professor Winchell accompanied 

 General Custer's expedition to the Black Hills, brought back 

 many valuable additions for the museum, and prepared a report 

 which contains the first geological map of the interior of the 

 Black Hills. 



In 1873 he was one of the organizers of the Minnesota 

 Academy of Natural Sciences, which he served during several 

 terms as president ; and he continued as one of its most active 

 members throughout his life. 



He was a fellow of the American Association for the Ad- 

 vancement of Science, and presided over its geological section at 

 the Philadelphia meeting in 1884. He was also one of the chief 

 founders of the Geological Society of America, in 1889. and
