DELAWARE COUNTY. 299 



oto, one mile above Millville. The stone church near this place is made 

 of the layers of No. 3 of the section at Colvin's lime-kilns. 



Samuel Perry's lime-kiln is situated about two miles above Millville, 

 and a mile east of the Scioto. It is one of that series known as the Delhi 

 kilns. His quarry affords an exposure of ten feet in the Delhi stone. 

 The stone is not strictly white, nor even buff, on fracture, but in con- 

 trast with the blue beds of the Delaware stone it has been denominated 

 white. It is a light gray, with brownish mottlings, caused by bitumi- 

 nous matter, weathering buff. The strike of these beds can be traced 

 by the topography north from Perry's quarry, and they are exposed so 

 as to induce more or less lime-burning on the land of William Lawrence, 

 William P. Jones, V. Dildine, John Powell, and P. Jones, and have a 

 gentle dip generally to the east or south-east. The quarry of Philip 

 Jones is so situated as to include about six feet of the bluish stone seen 

 at Colvin's lime-kilns lying below the Delhi beds. The upper portion 

 of his quarry is in the Delhi beds, as follows : 



No. 1. Delhi beds 4 ft. 



" 2. Blue beds, much resembling the Upper Corniferous, but less 

 fossiliferous, and more apt to be bituminous. They are hard 

 and crystalline, with frequent small deposits of calcite G ",

The gravel pike from Delhi to Middletown runs on the strike of the 

 Lower Corniferous, from a mile north of Delhi to Middletown, indicated 

 by a series of gravel knolls and ridges, which have a common direction, 

 about north-west. 



Ascending Mill Creek from Bellepoint, the Lower Corniferous is fre- 

 quently exposed. About half a mile from Bellepoint, on Richard Fry's 

 farm, and on those of Samuel and Homer Cole, nearly a mile further, 

 are bluffs of the heavy, even beds of the Lower Corniferous, which have 

 been compared to the Onondaga limestone of New York State. At Cole's 

 the section is as follows, in descending order : 



Section on Mill Ceeek. 



No. 1. Very fossiliferous, bituminous beds, 2 to 4 inches, with 



Strornatopora, Ccenostroma, Chxtetes, Favosites, etc., seen.. 4 ft. 6 in. 



" 2. Heavy, non-fossiliferous, magnesian beds, buff when dry ; 



suited for a cut-stone 18 " 



" 3. Conglomerate, embracing pebbles, sometimes four inches 

 in diameter, of Waterlime. These are water-worn and 

 embraced in a matrix of arenaceous magnesian lime- 

 stone; no quartz pebbles seen. (Oriskany) 1 " 6 "
