he bore all expenses of the survey, exclusive of publication. 

 The oncologist's regular salary as professor in the University 

 ($1,240) was continued (luring his connection with the survey. 



Small collections of rocks and minerals were made by both 

 Olmsted and Mitchell and deposited at the State University; but 

 these have disappeared. 



As to results: The survey is now of interest mainly from an 

 historic stand-point as being the earliest of the American State 

 surveys. It must be considered as little more than a rough geo- 

 logical reconnoisance of the State, during which spe(;ial attention 

 was given to minerals of economic; importance. And when one 

 considers the condition of geological science at the time the sur- 

 vey was made, the lack of experience in making geological sur- 

 veys, the limited time and fund at the disposal of the geologists, 

 but little more can be expected. Both Olmsted and Mitchell 

 did work of permanent value in locating and describing briefly 

 the ireoloirical formations of the middle and eastern sections of 

 the State. 



The publications of the survey consisted of four small annual 

 reports, each published as a part of a small volume of reports, 

 essays, etc., and distributed free, under the direction of the State 

 Board of Agriculture. The number of copies of each annual 

 report published was fifteen hundred.
