tory Survey of Minnesota, he published many papers in rapid 

 succession on the fauna of the state and began an extensive re- 

 port, the first vokune of which was completed in 1885. This 

 was a large quarto on the Mammals of Minnesota, ful^y illus- 

 trated with many colored plates and pen drawings. It was ac- 

 cepted for publication, but for lack of funds in the Survey never 

 saw the light. Years afterwards, in 1892, a small octavo was 

 published by the Survey made up of the more popular parts of 

 this work. The remainder is still preserved among his literary 

 effects. The season of 1881-2 was spent at the University of 

 Leipzig, and in 188o he was married to Miss Alice Keith of Min- 

 neapolis. This, roughly, may be said to constitute the first pe- 

 riod of his life, from 1858 to 1884. 



He was called to the chair of Geology and Natural History 

 of Denison University in the summer of 1884. He spent the 

 fall of that year at Denison, then returned to Minneapolis to 

 complete the work in progress in the Minnesota Survey, and in 

 the fall of 1885 moved with his family to Granville. Meanwhile, 

 in 1885, he took the degree of M. S. from his alma mater. It 

 had been his intention to continue his zoological work, and there 

 was great activity in this line during the entire period, but the 

 routine excursions made in the course of the instruction of his 

 geology classes showed him so much of interest in the local 

 strata that his chief labors while in Granville were upon the 

 fossils and stratigraphy of the Waverly free stones and shales 

 of Ohio. This work was abruptly cut short by his removal from 

 Granville in 1889 and, while never rounded out as he would 

 have liked, is probably his most important geological work. In 

 1885 he founded the Bulletin of the Scientific Laboratories of 

 Denison University, in which the greater part of his researches, 

 and those- of his pupils, on Ohio geology were published. 



His phenomenal success as a teacher during this and the 

 subsequent periods was due to factors, some of which are easily 

 seen — others are harder to define. After his attractive personal 

 qualities and magnetic enthusiasm, I should place his deep philo- 

 sophic insight and the fearless way in which he disclosed his.
