THE LOWER COAL MEASURES. 245 
covered in parts of Harrison, Washington and Center townships, but 
its horizon is reached in other portions of these townships. 
In Augusta, East and Fox townships there is a moderate develop- 
ment of the series, especially of the Upper Freeport coal. The coal as 
worked here is the extension of the Salineville field. It is on the edges 
of that basin, however, and is not only thinner than the coal of the Big 
Vein at Salineville, but it suffers much more frequent interruptions, 
long stretches of barren ground occurring between the small areas of 
productive coal. Only country banks are to be found throughout this 
portion of the county, except on the very eastern boundary of Fox, 
where the coal has been opened by the Salineyille operators. It proved 
too thin for any large business here, scarcely exceeding 3 feet. 
THE DELL Roy Coat FIELD. 
The one coal field of the county that has so far attained any im- 
portance as a mining center is that which is known as the Dell Roy or 
Sherrodsville field. It has recently been developed in connection with 
the building of the Connotton Valley Railroad, but at Leesburg, and 
also at Bowerston the same seam has long been worked to a considerable 
extent (see chapter I, pages 77-78-79). 
This field occupies the contiguous and connected portions of Center, 
Union, Monroe and Orange townships. It also extends into Monroe 
township of Harrison county. The coal seam on which its value 
depends is the Upper Freeport coal, and the field makes the second of 
the important basins of this seam so far found. The horizon of the 
coal extends beyond the boundaries named, it is true, but on the northern 
and western margins of this district in Brown and Rose townships, as 
also in Sandy and Fairfield townships, of Tuscarawas county, its chief 
interest and value are transferred to another element, viz., iron. It 
here supports the great Blackband deposits that have made the region 
famous. 
The Dell Roy coal field may be counted as beginning in Center 
township, in the vicinity of Carrollton. One mile southwest of Carroll- 
ton a number of mines have long been in operation for the supply of 
the town and the adjoining country. They all lie a little above the 
Indian Fork of Connotton or its several tributaries, in the valleys of 
which they are reached.
