176 PROCEEDINGS OF THE INDIANA ACADEMY OF SCIENCE. 



Cumings; the mushrooms by Reddick; the mammals by Hahn and the 

 beetles by Blatchley. In addition to the papers mentioned a contract had 

 been made by the writer with Dr. O. P. Hay of Washington, D. C, for his 

 paper on the "Pleistocene Period and its Vertebrata," which appeared in 

 Mr. Barrett's first report. 



At no time during the writer's service as Director was there an appropria- 

 tion of more than $4, 120 per annum for all salaries of assistants and of expenses 

 both for the field and office of the Department proper and also the State 

 Museum. This sum did not include the salary of the Director, which was 

 $2,500 per annum for the first twelve years, and $3,000 per annum for the 

 last four years. 



As showing some of the returns which the State received for this sum, it 

 may be said that in addition to the scientific papers above mentioned as 

 published in the reports and which are now used as reference or text books 

 in the high schools, colleges and universities of the State, the value of the 

 State's mineral resources advanced from $16,860,674 in 1895 to $44,971,003* 

 in 1910, an increa.se of $28,110,329 or 166 per cent. The value of the coal 

 mined in the State in 1910 was $20,813,659 or $3,952,985 more than the 

 total value of all the resources in 1895. If only one-third, or $9,337,000 of 

 this increase be attributed to the advertising done by the Department of 

 Geology, and the taxes on this be computed at 2.5%, they would amount 

 to $233,419 per annum, which would be a pretty fair profit on the $7,120 

 invested by the State each year in the Department of Geology. 



We have now completed our sketch of a century's work on the geology 

 of Indiana. We have seen how the yearly outi)ut of its natural resources, 

 other than soils and timber, have increased from a f(>w pelts of raccoons and 

 muskrats to a value of 45 millions of dollars. A century ago the white man 

 received from the red one this fair domain as the God of Nature made it. 

 To-day it is furrowed, creased, scarred, pierced full of bores and shafts and 

 pit holes, its rivers, sewers, its forests devastated, its soils depleted of their 

 fertility. The white man, ruled by the Gods of greed and mammon, has 

 left unscathed only a few spots as nature made them, spots like "Turkey 

 Run," the "Shades" and some of the wilder tracts in the southern counties. 

 He has left these solely because they were too rough to till, or were wholly
