These elements cannot all be found in any one section, but in some 
particular locality in the county each isa well-marked horizon. The 
differences of level between these elements vary greatly ; a characteristic 
section for all the central part of the county is given on page 95 of this 
volume from the Beech Hollow mines near Coshocton. 
CoaL SEAMS. 
The coal seams which are of economic importance are the Upper 
Mercer (No. 3a), the Brookville (No. 4), the Lower Kittanning 
(No. 5), and the Middle Kittanning (No. 6). Coshocton county has but 
small importance at the present time as a coal producing center, only 
80,000 tons being credited to it in 1883. The railroad trade is confined 
to a few banks only, but these are of very fair capacity ; the rest of the 
county at present supplies the demands of home consumption alone, 
waiting increased facilities and increased inducements to open up in the 
large way. In Tiverton, Newcastle, and Perry townships, on the 
western edge of the county, many efforts have been made to use the 
local streaks of the so-called No. 1 or Sharon coal, which lies at the top 
of the Waverly and at the bottom of the heavy Massillon sandstone. 
In no case has any degree of success been attained, though banks have 
been kept running for a year or two at a time. The coal is thin, of poor 
quality, and constantly liable to sandstone “ cut-outs.” 
The Lower Mercer Horizon furnishes here, as elsewhere, one of the 
most constant and certain guides in a study of stratigraphical order, but 
its usefulness is confined to that. In no instance in Coshocton county 
has coal from this horizon been found thick enough to mine, by the 
investigations of the present survey. 
The Upper Mercer Horizon. 
The Upper Mercer Horizon, though not so very stable as an 
element in the scale, is developed in one district in a very noticeable 
way, and will doubtless become a source of some revenue to the county.
