356 GEOLOGY OF OHIO. 
The most important opening in this coal in the county is that of the 
Licking Cannel Coal Company, in the western part of Hopewell town-- 
ship. The coal, by my barometer, is one hundred feet, and by report of 
railroad engineers, one hundred and four feet below Flint Ridge. It 1s 
capped by a thick bed of limestone, presenting with the coals, shales, 
and fire-clays, the following section:

Fire-clay. 
The limestone is highly fossiliferous, the lower part burning into a 
good quick-lime. The lower part of the fire-clay above the main body of 
the coal passes into an indurated fire-clay shale, which, in most places, 
makes a strong roof. The coal is of excellent quality, bright, compact, 
containing a moderate quantity of sulphur, and makes an excellent 
grate fuel and a superior gas coal. Fora time it was extensively used 
for the production of coal oil, the following average yield being obtained 
from the distillation of one ton of coal:

When crude petroleum fell to two cents per igs in 1861-2, the work 
was suspended, and, I believe has not since been resumed; the cost of the 
crude oil obained by distillation being about six cents per gallon. It is 
evident that our cannel coals and bituminous shales are capable of pro- 
ducing an abundant supply of cheap illuminating oils if that from a 
leum should fail. 
Nearly one-half the surface of Hopewell township is high eee: 
to contain this coal, but it is not persistent over all this area, and where 
present, it will probably not be always found thick enough to be profit- 
ably mined.
