OBITUARY. 



Charles Whittlesey. — Col. Whittlesey, whose decease is an- 

 nounced on page 412 of this volume, was a graduate of the United 

 States Military Academy at West Point in 1831. His work in 

 Geology began soon after, and in 1837 he was appointed an assist- 

 ant on the Geological Survey of Ohio, which was then under Mr. 

 W. W. Mather, and given the direction of the topographical de- 

 partment. From 1847 to 1851 inclusive, he was connected with the 

 Government Survey of Lake Superior and the upper Mississippi 

 with reference to mines and minerals ; and from 1858 to 1860 he 

 was by request of Prof. James Hall associated with him on the 

 Geological Survey of Wisconsin. In 1848, 1859 and 1864, he 

 made explorations in the mineral regions of Minnesota, and pub- 

 lished a report on the same in 1866. Mr. Whittlesey was the 

 author of papers on the drift of Ohio, the terraces of Lake Erie, and 

 various other subjects, and in one of them described a new coal 

 plant of peculiar type, which afterward received (through Dr. 

 Newberry) the generic name of Whittleseya. His latest contri- 

 bution to this Journal was in the spring of 1885, on the Pre- 

 glacial Channel of Eagle River. Two of his papers are among 

 the publications of the Smithsonian Institution. 



Col. Whittlesey returned to military life in 1861, and served as 

 State Military Engineer for Ohio volunteers, and afterward as 

 Colonel. He was born in Southington, Conn., and died in Cleve- 

 land, Ohio, which had long been his home.
