ISRAEL COOK RUSSELL 065 



In 1892 he was elected to the chair of Geology in the University 

 of Michigan, filling the vacancy created by the death of Alexander 

 Winchell; and he retained this position for the remainder of his 

 life. As a teacher he concerned himself chiefly with the instruction 

 of undergraduates, reserving a considerable share of his time and 

 energy for other activities. Most of the summers were occupied 

 by geologic field-work, chiefly under the auspices of the United 

 States Geological Survey; and winter leisure was devoted to Hterary 

 work. A few of the out-of-door studies were in Michigan and 

 near his home, but the greater number were in the mountains and 

 valleys of Washington and Oregon, and one was in the West Indies 

 during the eruption of Pelee. The Hterary output, in addition to 

 reports on summer work, comprised five semi- popular volumes and 

 a large number of scientific essays. 



A few fines will complete the statistical record of his fife. He 

 was married in 1886 to Miss J. Augusta Olmsted; and is survived 

 by his wife and family — three daughters and a son. The honorary 

 degree of Doctor of Laws was conferred on him by his alma mater 

 and by the University of Wisconsin. Geographers have signalized 

 his eminence in Alaskan exploration by naming a glacier and a 

 fiord in his honor. He was a member of many professional and 

 learned societies, served as vice-president of the American Asso- 

 ciation for the Advancement of Science and as president of the Mich- 

 igan Academy of Science, and at the time of his death was president 

 of the Geological Society of America. He was an associate editor 

 of the Journal of Geology. A list of his pubHshed writings compiled 

 by the librarian of the University of Michigan comprises 124 entries, 

 to which are added the titles of five unpubHshed manuscripts. One 

 of the latter — "Concentration as a Geological Principle" — was to 

 have been used, after revision, as his presidential address to the 

 Geological Society. Another, a report on the surface geology of 

 three counties of Michigan, had been transmitted to the state Geol- 

 ogist for publication. Of the published writings seven are books, 

 thirty are treatises of importance or reports of considerable extent, 

 fifty contain minor contributions to scientific knowledge or discussion, 

 and eighteen are to be classed as contributions to the popularization 

 of science.
