ties of iron, particularly if it should be found to serve likewise as a flux. 
The fossils in the upper beds are better preserved than in the lower, but 
good cabinet specimens are difficult to obtain. That locality alluded to 
before as Grubb’s quarry, in the southern part of the county, abounds in 
fossils, and I recommend it as a promising field for paleontological ree 
search. It was but little opened at the time of my visit, but as the stone 
obtained seemed to answer well for building purposes, it will doubtless 
be further developed and furnish many fossils, and possibly some that 
are new to science.

THE NIAGARA FORMATION. 
This designation, as well as many others in our geology, including the 
Bubject of the last paragraph—the Clinton—are derived from the account 
of the geology of the State of New York published some years since, and 
are taken from the occurrence of these strata in well known localities in 
that State. 
The Niagara formation is not exposed very extensively in Clinton. 
county, and dips far under the surface in Fayette. It lies immediately 
on the iron-stone or ore just referred to at Babb’s quarry, on Todd’s Tork. 
Here, proceeding from the upper strata of Clinton in the bed of the creek, 
near Babb’s quarry, we find, commencing at the Clinton, thence upward:

The best Niagara building stone in the county—smooth, fine-grained, even-bedded 
limes!one—approaching in qaality some sorts of marble. 
The supply of this building stone, however, is limited and much be 
low the demand. In the infe ior strata no trace of organic remains were 
found, their fine, even texture suggesting that they may have been de 
posited as calcareous mud in quiet water. In no part of the twelve or 
fifteen feet here exposed were organic remains found, except in the most 
meager quantity, here and there occurring a small mass of coral which 
is completely incorporated in the substance of the stone, being unbroken
