VI. 
THE CLINTON GROUP OF OHIO. 
BY A. F. FOERSTE. 
Pi^ospectus. 
The title, as given above, does not correctly indicate the scope of 
the papers here presented, but will very well serve to designate the 
field which I have laid out before me, and which I expect to cover by 
means of a series of articles, of which the present paper is the first. 
Descriptions of all the important exposures in the state, sections of the 
strata, analyses of rock, and paleontological features will be furnished 
wherever practical. A collection of fossils, which already bids fair 
to rival those at Waldron, Indiana, is expected to furnish the basis of 
a description of the fossils of the group as presented in this State. 
It is also intended to identify in an independent manner the true rela- 
tions of the geological strata usually included by the name Clinton Group, 
in our State and Indiana. Although it may be well to state at the outset 
that present indications seem to favor a closer relationship to Niagara 
strata, and especially those of the west, than is generally conceded ; nev- 
ertheless this conclusion has not been hastily drawn, and is not irrevoca- 
bly held. I shall only attempt to present the facts and state their 
probable bearing, and then allow the reader to draw his own conclu- 
sions. In order to determine more definitely the stratigraphical re- 
lations of the group with corresponding formations of the west, espe- 
cially those of Indiana, a series of sections taken at different 
stations, from both Ohio and Indiana, will be undertaken at an early 
date. Although the project in some respects may seem rather exten- 
sive, the large amount of material already collected gives promise of 
its ultimate accomplishment.
