DELAWARE COUNTY. 295 
separation between the blue Delaware limestone and the Delhi limestone 
seems to cross the Scioto at or near Bellepoint, perhaps a little south of 
that village. . 
About three-quarters of a mile below Sulphur Spring Station, Wild 
Cat Run joins the Scioto from the east. It is deeply and almost aston- 
ishingly : ut into the hard limestone beds, across which it keeps a fresh 
section «f the layers finely exposed. At the top of the bluff, where one 
reaches tlie general level by ascending the bed of this ravine (dry the 
most of the year), Mr. Peter Burlet has a fine quarry in the Delaware 
beds of the Corniferous. Near him Fred. Burlet has another. From the 
latter there is a continuous exposure to the level of the Scioto, where 
Mr. Richard Colvin’s quarry and kilns for lime-burning are operated by 
Charles G. Schmidt. Uniting all these exposures, the following section 
may be made out, in descending order :

““ 2. Heavy layers of Delhi stone; thin-bedded when weath- 
ered. Sixteen or seventeen years ago’these beds were 
extensively wrought for the abutments and piers of 
the railroad bridge over the Scioto, near here. Very 
heavy, large blocks were taken out, yet these layers 
are generally seen but 3 or 4 inches thick where 
weathered. Fred. Burlet’s quarry is just on the top 
of these layers, including 3 feet of the Delaware stone.

Colvin’s quarry is in the Delhi beds of the Lower Corniferous, near the 
bottom. The common fossils are seen here in the usual abundance. The 
* Perhaps Nos. 3 and 4 should be in one, the fossils and bituminous matter varying 
from one horizon to the other, causing the difference in lithological aspect.
