138 GEOLOGY OP OHIO. 



and at Zoar Station. In all this section it is rarely more than two feet 

 in thickness. In the south-western corner of Stark, however, in Sugar 

 Creek township, it becomes a bright, clean, and excellent coal, partially 

 open-burning, from three to three and one-half feet in thickness, and is 

 the seam mined at Fisher's bank, on the Tuscarawas Valley Railroad. 



In Holmes county Coal No. 3 becomes locally of much value. It is 

 the seam worked at Mast's, Collier's, and Chambers's mines; is about 

 four feet thick ; a semi-cannel, and good. At Harger's mill, in the eastern 

 part of Holmes county, it is five feet thick, part cannel, part bituminous. 

 In Mechanic township it is a true cannel, said to be eight feet thick ; 

 but is not worked, nor so exposed that its value can be determined. 



In descending the Tuscarawas river the coal seam under consideration 

 is seen at a great number of localities, which will be found described in 

 the reports on Coshocton and Muskingum counties. It dips nearly with 

 the fall of the stream, and is seen for the last time at the water level in 

 the base of Putnam Hill, near Zanesville, where it is an impure cannel 

 from six inches to one foot in thickness. Throughout this region the lime- 

 stone which overlies it is nearly continuous, and is often very cherty. 



In southern Ohio Coal No. 3 is a less constant feature in the geology 

 than further north. Its horizon is apparently marked, however, by a 

 limestone which, in Licking, Muskingum, Perry, Vinton, and Jackson 

 counties, lies from 120 to 170 feet above the Jackson coal. The coal 

 itself, however — of which the place is below the limestone — is generally 

 wanting, and where present is very thin. Nearer the Ohio, in Lawrence 

 and Scioto counties, as I learn from the reports of Prof. Andrews, both 

 the coal and limestone have disappeared.
