I. Second Annual Report on the Geological Survey of the State 
of Ohio; by W. W. Maruer, Principal Geologist, and the 
several Assistants.—Columbus, 1838. 
An abstract of the first report for 1837, was given in this Jour- 
nal, Vol. xxx1v, 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 survefys 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, &¢.—in pointing out the limits of’ the differ- 
ent formations, thus directing the applications of enterprise t0 
oper fields and preventing useless expenditure in places where ~ 
investigation for valuable minerals would be fruitless. ‘The 4e- 
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 mort 
condition. Ohio, in’'its most thickly settled portions, is found 1 
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 
would be benefitted by the geologieal survey but the coal and 
iron region ;” and “the geologists were directed to make surveys 
of some counties which were not expected to feap any benefit 
from the survey,” and supplies of useful materials for the arts
