I. Second Amiual Report on the Geological Survey of the State 

 of Ohio ; by W. W. Mather, Pi^incipal Geologist, and the 

 several Assistants. — Columbus, 1838, 



An abstract of the first report for 1837, was given in this Jour- 

 nal, Vol. XXXIV, p. 196. There existed a rumor, that the survey 

 would not be continued. The Legislature, however, made an- 

 other appropriation, and the results of the labors of the second 

 year's survey are here presented. The work has never been re- 

 sumed, and thus has ended for the present, we trust not finally, 

 an undertaking, in its nature calculated to spread innumerable 

 benefits throughout the whole state. Upon whom rests the re- 

 sponsibility it is not our province here to inquire. That much 

 dissatisfaction has existed in certain quarters is, we believe, true. 

 It is also no doubt a fact, that from the surveys heretofore made, 

 very important advantages have been derived to the state, which 

 are availed of in the manufacture of salt and iron, in the ex- 

 ploration of coal, &c.-^in pointing out the limits of the differ- 

 ent formations, thus directing the applications of enterprise to 

 proper fields and preventing useless expenditure in places w^here 

 investigation for valuable minerals would be fruitless. The de- 

 velopment of the physical resources of a country — of ores and 

 coal, materials for architecture and the arts, of saline and medi- 

 cinal springs, excites a degree of healthy industry, whose returns 

 enrich the inhabitants and at the same time improve their moral 

 condition. Ohio, in its most thickly settled portions, is found to 

 be richly stored with mineral wealth ; and these districts being 

 best known and most accessible, were the first examined by the 

 geologists. The results of the former examination seem to have 

 excited some jealousy in other quarters, " that no part of the state 

 M^ould be benefitted by the geological survey but the coal and 

 iron region ;" and " the geologists were directed to make surveys 

 of some counties which were not expected to reap any benefit 

 from the survey," and supplies of useful materials for the arts
