80 GEOLOGY OF OHIO. 
styled Coal No. 7, but the same seam becomes Coal No. 6 at Sherrods- 
ville, Dell Roy and Carrollton. Traced down the Connotton Valley, it 
is found in the border hills on the Bartholomew farm, 1 mile below 
Sherrodsville, 108 feet above the valley. Two miles below this point, 
at Moughimon’s Mills, the Kittanning coals are both found, in alto- | 
gether normal relations, the Lower seam being at the level of the stream. 
From this point they are followed in clear and definite sections to Zoar 
Station and Mineral Point. 
To these same localities the general series has been followed, as it 
will be remembered, from the Pennsylvania line. From Zoar Station 
to the southward and westward, the series has been traced without in- 
terruption or question, so far as the main elements are concerned, through 
the deep valleys of the Tuscarawas and the Muskingum to Zanesville. 
Through all of this district, Newberry’s Tuscarawas county section applies 
without essential modification, and we could pass at once across the 
three counties that occupy the interval without losing our hold on the 
series, but it will be well to give a few typical sections that occur here. 
One digression, it is, however, necessary to make. The Cambridge 
coal field is one of the most important of the State, and its series rests 
to some extent under the ambiguity of the double numbers. It has 
been identified by Stevenson as No. 7 of Newberry’s series in Tus- 
carawas county. This refers it to the Blackband or Upper Freeport 
horizon, and here, as will be clearly shown, it belongs. 
The district can be reached most advantageously by the line of the 
Wheeling and Lake Erie Railroad, formerly the Cleveland and Marietta 
Railroad, which leaves the Tuscarawas Valley at New Comerstown. 
At this last-named place, we find the following section. It extends 
from the Lower Mercer limestone, which is shown at Suydam’s Lock, 
to one of the coal banks that is worked for the supply of New Comers-
