As a professor in Columbia College, Dr. Newberry received a 

 liandsome salary aud found much time to devote to liis chosen 

 work outside of his college duties. During this period of 

 twenty-four active years he was incessantly working, and always 

 with more upon his hands than he could properly dispose of. 

 He accomplished, however, by his industry, a vast amount of 

 the best work of his life. All but thirty-six of his 210 published 

 papers were written after 18GG. 



Between 18G9 and 1882 he published the several reports of 

 the Ohio Geological Survej', consisting of three brief reports of 

 progress and seven volumes of final reports, four of these in 

 geology, two in paleontology and one in zoology, and a geolog- 

 ical atlas. He personally did a large part of the field Avork and 

 wrote the descriptions of a number of the counties. In the 

 course of his work about Lake Erie he arrived at important con- 

 clusions concerning the preglacial drainage of the glaciated 

 region and of the geological history of the Great Lakes, which 

 later investigations have justified and which show his powers of 

 insight and generalization. 



Earl}' in his work. Dr. Newberry made practical application 

 of his knowledge, his first paper in economic geology bearing- 

 date 1857. Thirty-eight of his titles fall into this class, most 

 of them, however, after 1880. His opinion came to be highly 

 valued and much sought after in relation to various kinds of 

 mining properties, and frequent journeysweremade in difiterent 

 directions, even to Mexico. Probably no other man has had, 

 from personal observation, so full knowledge of the geology 

 and resources of our national domain. The economic collec- 

 tions of the Columbia Museum were enlarged by these scien- 

 tific trips to mining and quarrying districts. He also had a 

 practical interest in the application of his science, and at one 

 time was a large holder of petroleum lands, and had interests in 

 Vermont marble quarries. 



Dr. Newberry was one of the editors of Johnson's Cyc]oj)edia, 

 and wrote several of the papers in Appleton's Cyclopedia. 



It is evident that Dr. Newberry's early experience in the 

 western fields greatly influenced his? mind aud all his later work. 

 To an intellect naturally comprehensive aud sympathetic the 

 years spent among the imposing natural features of the west 

 added great breadth and poAver. The sweep of his experience, 

 with his learning and mental grasp, enabled him to treat geo- 

 logical problems in a large wa}'. He was never trivial orflip])ant 

 or superficial. In his speaking and writing the loftiness of his
