No. 7. Heavier beds (6 to 20 inches'), but of the same texture as the 

 last; fossiliferous ; blue; the horizon of the best quarries 

 at Delaware, showing the usual fossils and lithological 



characters (Hamilton?) 6 feet. 



" 8. Crinoidal beds, fossiliferous, of a lighter color ; not showing 

 blue ; generally massive, or 8 to 36 inches, but weathering 



into beds of 3 to 5 inches (Corniferous limestone) 6 " 



" 9. Heavy or massive beds of crinoidal limestone, which weath- 

 ers off by crumbling into angular pieces of an inch or two ; 

 light gray, or bnff ; with large concretions of chert be- 

 tween it and the last. This seems to contain all the fos- 

 sils characterizing the Lower Corniferous, as that term has 

 been used in reports on other counties. Below, becoming 

 more bituminous, less crinoidal, but equally fossiliferous 

 (Corniferous limestone), seen 11 "

There is a strong dip here to the east. Mr. Case's quarry is in No. 7. 

 From this place to near the county line the Delaware limestone is ex- 

 posed frequently along the right bank of the river, hut nowhere afford- 

 ing so complete a section as that at Case's, till finally it entirely goes 

 below the water, and the shale and slate take its place in the banks. 



About a mile and a quarter south of Bellepoint, on the west side of the 

 Scioto, the Upper Corniferous is opened by W. T. Ropp, M.D , and Wil- 

 liam Cutler. The amount exposed is about three feet, though a ' : sink- 

 hole" in the center of Dr. Ropp's quarry, which allows the disappear- 

 ance of a considerable stream in freshet time, affords the means of an 

 imperfect inspection of about ten feet more. Beds lie nearly horizontal, 

 or show a slight dip north. Dr. Ropp's well, fifty rods north of his 

 quarry, struck the same limestone. After passing fifteen or eighteen 

 feet into the blue stone, the beds quarried at Delhi were encountered. 

 At the river, directly east of Cutler's quarry, the lower poition of the 

 Corniferous is seen on Dr. Ropp's land exposed about ten feet. About 

 midway up the bank, intermediate between the quarry and the river, 

 the Delhi beds are seen in prominent outcrop on the land of Dr. Ropp. 

 About half a mile south of Cutler's quarry the heirs of Leander Stone 

 own a quarry in similar limestone. One mile still further south Mr. 

 Perry Marsh has another quarry in the same beds, situated in a ravine 

 tributary to the Scioto. Beds from four to six inches. Brainerd Willis 

 has a quarry three-quarters of a mile south of Bellepoint, about a quar- 

 ter of a mile east of the Scioto, said to be in the blue limestone. Elijah 

 Kent has a blue stone quarry opposite the sulphur spring, on the east 

 side of the Scioto, situated half a mile from the river. The line of the
