Geology 
The accompanying statement of the Division of Geology 
of the Conservation Commission indicates some of the more 
important specific activities of the Division since its inception 
in 1919. It should be understood, however, that the Division 
of Geology of the Conservation Commission is the lineal des- 
cendant of the old Indiana Geological Survey; and that the 
chief of the Division, Professor Logan, State Geologist, is 
Professor of Economic Geology in Indiana University, and 
all of the scientific staff of the Division, with the exception of 
one man, are members of the staff of the Department of Geol- 
ogy of Indiana University. 
The following additional Ltcts also need to be mentioned. 
The Indiana Geological Survey came into existence in 1837. 
After two years it ceased operations, but was revived in 1859, 
and has been serving the state ever since. The second State 
Geologist, Richard Owen, was a member of the Faculty of 
Indiana University. W. S. Blatchley, State Geologist from 
1894 to 1911, was a graduate of Indiana University. The fol- 
lowing are a few of the graduates and of the faculty of the 
University who have contributed to the manifold services and 
publications of the Survey, often without remuneration : J. W. 
Beede, W. S. Blatchley, J. C. Branner, H. N. Coryell, E. R. 
Cumings, J. J. Galloway, E. M. Kindle, W. N. Logan, C. A.
