GEOLOGICAL AND NATURAL HISTORY SUR^ KYS. 367 



As to the inethods adopted in the prosecution of the survey little 

 information has been left on record. They were unquestionably of 

 the simplest character. Olmsted, during 1824, seems to have devoted 

 himself mainly to the middle section of the State, searching particu- 

 larly for minerals of economic value, but with little regard for the 

 geological structure as a whole. Tlie same may be said of Mitchell. 

 Though working for a longer period, he succeeded in gathering up a 

 larger and more systematic series of data, from which he was later 

 enabled to compile a geological map of the State. 



Musoum or cahlnet. — There was nothing in connection with the 

 survey which could be called a museum. Professor Mitchell men- 

 tions in his report ' " the cabinet " of the university, where a rather 

 complete series of specimens illustrative of the geology of the counties 

 visited had been assembled. At the present day, however, no rem- 

 nant of this collection is to be found. 



There was no library belonging to the survey and no '' exchanges " 

 to be disposed of. 



Salaries and expenses. — Obviously, neither Olmsted nor Mitchell 

 could have received any salary' for their work, the amount appro- 

 priated being only for expenses, nor has there been found any record 

 of any payment to Mr. Rothe. No record of the detailed expendi- 

 tures of the survey- has been found. The report of the State auditor 

 and treasui-er (1824-1828) reads as follows: "Paid D. Olmsted by 

 State treasurer for geological survey * * * , etc." ; and in case of 

 Professor Mitchell. '' To Professor Mitchell for his services and ex- 

 {)enses in making a geological survey of the State, agreeable to the 

 direction of the general assembly, on warrant from the president of 

 the board of agriculture, * * '^ $250." 



The total expenditures for the five years (excluding cost of pub- 

 lications) amounted to $1,250. The expenditures for printing were 

 paid out of the general fund of the State treasury. 



P'liblicaiiom. — The publications of the survey consisted of small 



nnual reports; these, four in number. Avere each printed as a part 

 of a volume of reports and essays published annually under the 

 direction of the board of agriculture. They are as follovrs:
