TUSCARAWAS COUNTY. 73° 
feet in thickness. It lies, by barometer, just one hundred feet above 
Coal No. 6, or one hundred and fifty feet above the railroad at Uhrichs- 
ville., Passing southward over the hill, its outcrop may be again seen 
near the house of Mr. Job Gatchell. Further up the Stillwater, eight 
miles above Uhrichsville, Coal No. 7 is seen on the farm of Mr. Wallace, 
where it may be directly connected with No. 6. About twenty feet 
- below it, is coal No. 6a, two to three feet thick, part cannel; and sixty 
feet below this, ten to twelve feet above the creek, is the No. 6, for- 
merly worked for boiling brine and making copperas—a locality refer- 
red to in the notes on Coal No. 6.. About a mile south, Mr. William 
Houck has opened Coal No. 7, where it appears better than at any other 
place examined in the county. It is four feet ten inches thick, very 
clean, bright and black, and apparently free trom impurities. On the 
east side of the Stillwater, near by, is what seems to be a good exposure 
of blackband iron ore, to which reference will be made further on. 
Higher up in the valley of the Stillwater, and beyond the Harrison line 
at Tippecanoe and Freeport, Coal No. 7 is extensively worked, and chiefly 
supplies the demand for fuel in this vicinity. 
In going north-east from Dennison toward Leesburg, the rapid easterly dip 
of the rocks brings Coal No.7 under good cover before crossing the county 
line. It is here of unusual thickness, ranging from four to six feet, but 
is generally divided by one or two partings, and is not of first quality. 
From these facts, it wiil be seen that Coal No. 7, though widely dis- 
tributed, through the county, is only of local importance, and that its 
chief interest.is derived from the iron ore vse which it is so goperelly 
associated. 
In the south-eastern part of: the county, a thin coal is found above No. 
7, but it is nowhere of workable thickness, so that the bed we are consid- 
ering may be reckoned as the highest workable coal of the lower series. 
As will be seen by reference to the general description of the carbon- 
iferous system, and the reports on Harrison and Belmont counties, above 
Coal No. 7 is a mass of shales and sandstones, with a few thin seams of 
coal, which constitute what have been called the Barren Measures. 
Above these lie, first, the Pittsburgh coal, with its associated heavy lime- 
stones, and then the other members of another and higher group of coals. 
A striking feature in the Barren Measures is formed by beds of red or 
mottled shales; and it may be worth while to remember that no such 
strata are ever found below Coal No. 7; so that, wherever these red shales 
are seen, it may be inferred that all the workable coals are below and 
none above them. 
There is also found in many localities above Coal No. 7, a more or less
