GEOLOGICAL AND NATURAL HISTORY SURVEYS. 397 



The average expense of the survey of each county had thus far 

 been about $1,000, while the benefit resulting to a single one of these, 

 arising from the increased valuation of real estate incident to the 

 developments of mineral \\ealth, was estimated to be at least $100,000, 

 and by some as $500,000. So it was with other counties as their 

 resources were juade known and were appreciated. 



Although the matter of continuing the survey was of such grave 

 importance to the best interests of the State, a change of political 

 control was allowed to interrupt the work, and as time passed the 

 chance of resuming it seemed to grow more and more distant. 



The legislature ordered that 5,000 copies of the report of the 

 geological board be printed. For pajnient of arrearages for services 

 of the corps and for procuring engravings a sum not exceeding $4,000 

 was appropriated bj' law March 18, 1839. 



The legislature directed that all books, papers, instruments, ap- 

 paratus, and collections of any kind in possession of the members of 

 the late corps be deposited with the Ohio Historical Society for safe- 

 keeping, there to remain until called for by the State. 



By act of the legislature in March, 1841, there was appropriated 

 for paying the expenses of labeling and arranging specimeris col- 

 lected by the geological board, and distributing such portions as were 

 intended by law for the literarj- institutions of this State, a sum 

 not exceeding $300, to be expended under the direction of the 

 governor. 



(rovernor Gorwin, in his message of December 7, 1841, reported 

 that the collections resulting from the survey had remained until a 

 late day without classication ; that in view of the small appropriation 

 made during the last session for labeling and arranging specimens 

 for preservation here, and for distribution to the literary institutions 

 of the State, he had procured the services of W. W. Mather, whose 

 work would be completed by Januaiy 1, 1842 ; and he earnestly recom- 

 mends a continuance of the survey on a limited and economical scale 

 especially in reference to the agricultural interest. 



If by the labors of a geologist so appointed 1 bnsbel of wheat to the acre 

 extra should be raised it would pay the salary of such an officer twice told for 

 many years to come. 



CoIlectionJi. — Early in 1842 Doctor Mather reported to Governor 

 Corwin that the specimens, nine suites in all, were labeled. Two 

 suites were reserved for the State ; the rest were boxed and readv for 

 distribution. One suite belonging to the State was arranged by coun- 

 ties, and, being duly catalogued, Avas on exhibition in glazed cases. 

 The other suite was still in boxes from lack of cases. A different ar- 

 rangement was contemplated. To arrange them in a manner uniform
