206 : GEOLOGY OF OHIO. 
Where the clay is mined, the coal is secured at little additional outlay, 
and consequently more of it comes to use than’ would be worked on its 
own account. Its quality here is generally very poor. It runs below 
3 feet in thickness. 
The Middle Kittanning is a thin seam, ranging from 20 to 32 inches 
in thickness, but its quality is excellent, and it is consequently much 
sought for. Dry Run, above East Liverpool, is a locality from which 
a large amount of this seam, thin though it is, has been taken out. 
The coal is bright, strong and clean. It mines large, and is consequently 
known as the “Block Vein” quite widely. It is the main reliance of 
the adjacent country for household fuel, for which purpose it is happily 
adapted. | 
The Fredericktown Anticlinal lifts this series a good deal above 
the river at Liverpool, and as far as Wellsville. “The Dry Run 
coal is not largely worked in this space, though it is generally found. 
Openings to it have been made on almost all of the farms. At Liver- 
pool, the Lower Freeport (Roger) coal is found in moderate develop- 
ment, and has been worked for a long time. The seam is but 30 inches 
thick, but its quality is fair. The following section is obtained at 
Liverpool:

The same seam is mined by Riley McKinnon, by Basil Sims, 
Phanuel Sims, and by Martin, Fisher, James, and Golden at different 
points along the valley. 
Several mines are opened in the Upper Freeport seam, two miles 
back of Wellsville. One of the largest is on the McGough farm. The 
section is as follows:
