About 1% miles farther up the railroad, at Peck, are the exten- 
sive quarry and mill of the Waverly Stone Co., which also obtains 
its stone from the Berea sandstone. There is also a small quarry 
located on the eastern side of the valley, called Peck’s quarry. 
Mr. I. Combs, the superintendent of the Southern Ohio 
Stone Co. has not seen the Waverly brown sandstone, which 
occurs near the base of the Cuyahoga shales, overlying the Sun- 
bury shale, in the hills bordering Crooked Creek ; but the locality 
east of the river, where it caps the hill on the Gregg farm, is 
well known to him. He also reported excellent outcrops of it 
farther north on the eastern side of the river, about one mile 
below the Omega river bridge. Dr. Orton reported this sand- 
stone as 10 feet in thickness on his section of the ‘‘Waverly Sys- 
tem in Pike and Ross counties” with 35 feet of blue shales 
between it and the top of the Waverly | Sunbury ] black slate.? 
He correlated it with the stone obtained high in the bluffs on 
the northern side of the Ohio river near Buena Vista and called 
it the Buena Vista stone,? which correlation is restated in his 
last account of the geological scale of Ohio. 
Buena Vista—TYhe extensive quarries near the head of an 
east branch of Lower Twin Creek, some five miles northwest of 
Beuna Vista, were studied. A tramway extends from the town 
to the quarries, and a highway may be followed to No. 4 on 
the tramway, within about one mile of the older quarries, which 
are no longer worked. On the bank of the creek, just above 
No. 5 of the tramway, is a good exposure of the upper part of 
the Ohio shale, which begins at creek level and extends up the 
bank for 24 feet, when the shales are covered by soil. Two 
species of Lingua were found near the top of these shales, the 
most common one resembling quite closely Lingula Wilhamsana 
Girty, while a larger species is also found lower in the bank. 
A sandstone ledge in the lower part of the Bedford is shown 
not much farther up the bank.
