666 GEOLOGY OF OHIO. 



It is, however, probably the Coal No. 3, and from eighty to ninety feet 

 above the Maxville limestone, judging from the sections given by Prof. 

 Andrews in the Report of Progress for the year 1869. It is substantially 

 on this horizon that the Calcareous iron ore, containing fossils, is found, 

 which has been mined northwest of New Lexington, and taken to the 

 Zanesville furnaces. 



The interval between the coal and cherty limestone above referred to, 

 is disclosed in a well sunk near the base of the limestone, and a short 

 distance from the depot at New Lexington. It is there a thin-bedded 

 sandstone, passing into sandy shale upon approaching the coal below- 

 The limestone coal above it shows an outcrop from two to two and one- 

 half feet, not of good quality. The limestone above is from two to four 

 feet, cherty, in places passing into black flint, andwasheretninedby the 

 aborigines for the manufacture of flint implements. Their old excava- 

 tions are to be seen just north of the railroad at New Lexington. The 

 limestone is capped with an iron ore which is thin at the places of 

 exposure, but further explorations should be made for it on this horizon. 



About twenty feet above this limestone is a thin coal of no value, and 

 eighty feet above this, according to Mr. Nichols' measurements, is the coal 

 called here the Lower Moxahala, which reaches, in places, a maximum 

 thickness of five and one-half feet ; is a hard, dry-burning coal, of light 

 specific gravity, containing some sulphur, and yielding a white ash. 

 This coal is also mined at Cherry Station, where it is dry-burning, of 

 good quality, and five feet thick. 



The Great Vein coal, twenty to twenty-five feet above the last, is also 

 mined at Cherry Station, where it is four feet to four feet nine inches 

 thick, more bituminous than it is further south, and with too much sul- 

 phur for a smelting coal. At an exposure in Section 13, Pike township, 

 the upper bench is cut out and the middle and lower benches measure 

 ten inches, and from twenty to thirty inches respectively. Near north- 

 west quarter of Section 17, Bearfield township, the upper bench is twenty 

 inches, middle bench twelve inches, lower bench twenty-six inches; 

 upper bench quite shaly. In the south-west quarter of the same section 

 the coal is five and one-half feet thick, with six feet of carbonaceous 

 shale above. The changes that occur in the coal southward are indi- 

 cated by the following section near the North Tunnel of the Atlantic and 

 Lake Erie Railroad : 



Drab shale at top. 



Shaly coal 14 inches. 



Shale 2—4 " 



Coal 12 " 



Shale 1—2 "
