was its president in 1 ( K)2. He was a member of national societies 

 of mineralogy and geology in France and Belgium. In the In- 

 ternational Congress of ( ieologists he became a member in 1888, 

 being reporter for the American committee on the nomencla- 

 ture of the Paleozoic series; contributed papers in French to 

 its subsequent meetings at Boulogne and Zurich; and attended 

 its triennial meeting last August in Toronto. 



Under appointment by President Cleveland in 1887, Pro- 

 fessor Winchell was a member of the United States Assay Com- 

 mission. His geological reports received a diploma and medal at 

 the Paris Exposition of 1889, and a medal at the World's Fair 

 in Chicago in 1893. 



He was the chief founder of the American Geologist, a 

 monthly magazine, which was published in Minneapolis, under 

 his editorship, during eighteen years, 1888-1905, in two volumes 

 yearly, forming a series of thirty-six volumes. This work, in 

 which he was much assisted by Mrs. Winchell, greatly promoted 

 the science of geology, affording means of publication to many 

 specialists and amateurs throughout this country. It also brought 

 out many biographic sketches, with portraits, of the principal 

 early American workers in this wide field of knowledge. 



In one of the bulletins of the Minnesota Geological Survey, 

 entitled "The Iron Ores of Minnesota," 430 pages, with maps, 

 published in 1891, Prof. N. H. Winchell had the aid of his son, 

 Horace Vaughn Winchell ; and in a text-book, "Elements of 

 Optical Mineralogy," 502 pages, 1909, he was associated in au- 

 thorship with his younger son, Prof. Alexander Newton Win- 

 chell, of the University of Wisconsin. During parts of the 

 later years of the Minnesota survey he was aided by his son-in- 

 law, Dr. Ulysses S. Grant, professor of geology in the North- 

 western University, Evanston, Illinois. 



In 1895-96 Professor and Mrs. N. H. Winchell spent about 

 a year in Paris, France, and again he was there during six months 

 in 1898, his attention being given mainly during each of these 

 long visits abroad to special studies and investigations in petrol- 

 ogy. 



My association with Professor N. H. Winchell began in 

 June, 1879. Coming from the Geological Survey of New Hamp- 

 shire, in which I had been for several vears an assistant, I was
