746 GEOLOGY OF OHIO. 
The strata have a rapid dip to the south and west from Croxon’s Run, 
and local dips were reported as high as eighty feet in two hundred 
yards. | 
SLOAN’S STATION. 
About a quarter of a mile above Sloan’s Station are the fire-brick 
works of John Francy. Coal No. 3 here lies about twen:y-three feet be- 
low the railroad. It is from thirty to forty inches in thickness, and of 
somewhat better quality than where mined further up the river. It is 
overlain by a stratum of micaceous sandstone twelve to fifteen feet in 
thickness, which forms a remarkably smooth and firm roof throughout 
most of the mine. Below the coal is soft, plastic fire-clay, thirteen feet 
in thickness, which supplies the material for the factory. Under this is 
a hard, silicious clay, of unknown thickness, not worked. In one part of 
the excavation made to remove the fire-clay, it was found to assume 
locally the hard, non-plastic character of the Mineral Point and Mt. Say- 
age clays. This phase of our fire-clays is much less uncommon than is 
generally supposed, as most of them exhibit some local manifestation of 
it, and although most characteristic of the clay under Coal No. 5, in Tus- 
carawas county, is only local there, and can not be trusted as a means for 
identifying clay seams at distant points. Mr. Francy’s works are among 
the most extensive on this side of the river, producing about two million 
bricks annually. 
The section of the strata in the hills above Sloan’s Station is as follows:
