and adds materially to the wealth and economic resources of the 

 State. Jackson County owes much of its development to the presence 

 of this bed which has been mined for over fifty years. 



At its southern limit in Scioto County, the Quakertown coal lies 

 half-way between the Anthony coal below, and the Bear Run coal 

 above, the average interval in each case being 35 feet. Northward 

 in Jackson County the latter interval varies from 20 to 30 feet, while 

 that between the Quakertown coal and the Sciotoville clay averages 

 40 feet. * In Muskingum County the horizon measures from a few 

 to 70 feet above the base of the Pennsylvanian system, the variation 

 being due to the irregular upper surface of the Mississippian rocks. 2 

 At the extreme northeastern extension of the Pottsville formation 

 in Mahoning County, the Quakertown varies from 50 to 80 feet above 

 the Sharon coal. 3 



The Quakertown coal reaches its maximum development in Coal 

 and Milton townships, Jackson County, where it is mined over an 

 area of forty square miles. Among the principal mining centers 

 are Wellston, Coalton, and Glenroy. The bed reaches a thickness 

 of 4 feet in places, but averages for the county 2 feet 6 inches. It is 

 of excellent quality, and for the most part is free from shaly partings, 

 though shales form the roof of the coal except where they are occasion- 

 ally replaced by sandstone. The productive field extends northward 

 into southern Vinton County as far as Allensville, Elk Fork, and 

 Vinton Furnace. To the north and south the bed becomes thin and 

 of slight economic value although it is mined in places for local domestic 

 use. In Scioto County it is often wanting, but where present reaches 

 a maximum thickness of 1 foot 10 inches, while in Muskingum County 

 the average thickness measures 1 foot 8 inches. Its value in the 

 latter county, however, is lessened by shaly partings % to 6 inches 

 thick. Farther northward carbonaceous shales with very thin coal 

 layers mark the horizon, while in Mahoning County, Dr. Newberry 

 reports that the member consists of alternating gray and black shales 

 and sandstones with an occasional thin coal bed. 4 



The shales which form the roof of the Quakertown coal in Jackson 

 County have been found to be very sparingly fossiliferous. A diligent 

 search in the shales associated with the Quakertown coal at various 

 localities in southern Ohio was rewarded by only a few crushed speci- 

 mens, all of the same species, from three places in Coal Township, 

 Jackson County. With the exception of Lingulas from one locality 

 in Summit County, these forms constitute the only fossils discovered 

 on the horizon.
