Obituary. 



Professor Newton Horace Winchell, formerly the state 

 geologist of Minnesota, died on May first, after an operation in 

 the Northwestern Hospital, Minneapolis, Minnesota. Winchell 

 was born at Northeast, New York, December 17, 1839. In 1866 

 he was graduated at the University of Michigan. Before this 

 time, however, he had done geological work on the Michigan 

 State Survey, and three years after his graduation he became 

 assistant state geologist. From 1870 to 1872 he was connected 

 with the Geological Survey of Ohio, and from 1872 to 1900 served 

 as state geologist of Minnesota ; during this latter period were 

 issued under his direction the six large volumes dealing with the 

 geology and paleontology of the state, which are so widely known 

 for the careful work they contain. Professor Winchell organized 

 and edited the American Geologist, a highly creditable monthly 

 periodical which appeared from 1888 to 1905, after which time it 

 was amalgamated with Economic Geology. In 1902 he was 

 president of the Geological Society of America, and he was 

 the founder of the Minnesota Academy of Sciences. Since 1905 

 he had been in charge of the section of archeology of the Min- 

 nesota Historical Society, where he jmblished last year an inter- 

 esting volume entitled " The weathering of aboriginal stone 

 artifacts. No. 1. A consideration of the paleoliths of Kansas." 



Professor Winchell was planning to celebrate his golden wed- 

 ding anniversary next August, and last winter at the Princeton 

 meeting of the Geological Society of America he looked the picture 

 of health, and as if he had many more years of activity ahead of 

 him. He is survived by his widow, two sons, Horace V. Win- 

 chell and Professor Alexander N. Winchell, and three daughters, 

 Mrs. U. S. Grant, Mrs. F. N. Stacey and Mrs. B. Draper Dayton.
