' COAL MINES OF LICKING COUNTY. 909 
Flint Ridge has always been counted one of the most anomalous 
and at the same time one of the most interesting formations in Ohio. 
Its approximate areas, for it consists of more than one outlier, are laid 
down upon map No. 5, being here represented for the first time. 
Though the boundaries are laid down distinctly on the map, the letter- 
ing is quite obscure, but the Ridge can be recognized as constituting 
the only shaded areas in Hopewell township of Licking, and also in 
Hopewell township of Muskingum county. By an inspection of the 
map it will be seen that the Ridge isa remnant left from long con- 
tinued erosion. That large areas of the formation have been removed 
is attested by the enormous quantities of flint that cover the slopes, as 
well as by the situation of the remaining masses of the Ridge. The 
flint appears toe belong to the Ferriferous limestone horizon. The 
thickness of the sheet it is hard to determine, as there are few distinct 
sections of it to be found, but most of it would probably keep within an 
outside limit of 10 feet. 
The cannel horizon lies about 100 feet below the flint. The section 
including it is about as follows:

The coal is opened near the western boundary of the basin. The 
land is high enough to hold the seam for several miles to the westward, 
but there are no indications of its presence. 
In fact, in the westernmost entries of the present mines, the coal 
seemed to come to an abrupt termination. The field extends to the east 
and south, but just how far there has not been exploration enough to 
determine. The probabilities are in favor of a considerable tract. 
Some of the parties best acquainted with the territory estimate the pro- 
ductive area to be not less than 1000 acres. A shaft sunk + mile east 
of the present mines found 3 feet of good cannel. Two miles to the 
eastward of the mines, Capt. John M. Loughman reports 2 feet 8 inches
