280 GEOLOGY OF OHIO. 
In Sugar Creek township a coal seam has been somewhat worked 
in past years that has been variously identified as Coal No. 3a (Upper 
Mercer), or Coal No. 36 (Tionesta). The interval between these coals 
is small, but from the facts given in regard to the occurrence of the 
last-named seam in Lawrence township, it seems more probable that 
the Winkelpleck, Yoedder and Nead coals, found near the certer of the 
township, should be referred to the Tionesta horizon. Whatever the 
seam may prove to be, it is not likely to add very much to the fuel 
supply of the township, at least for some time to come. A good thick- 
ness is reported in several of these old openings, the coal ranging from 
3 ft. to 4 ft. 2 in., but the seam is nowhere worked at the present time, 
so far as known. In other words, it does not appear able to maintain 
itself in competition with the upper seam of this same region. 
The Middle Kittanning coal may be fairly inferred to extend 
throughout Bucks township, without serious interruption, as it is found 
in good development both to the west and east of the township. The 
land lies mostly in high, dividing ridges, that rise far above the horizon 
of the coal. 
THE FREEPORT COALS IN TUSCARAWAS COUNTY. 
Reference has been already made, in passing, to the several elements 
of the Freeport Group as they have come into view in the general sections 
that have been reported. Attention has been repeatedly called to the 
fact that the Upper Freeport coal is far less important in Tuscarawas 
county than the blackband ore that accompanies or replaces it in the 
central townships. The ore of this horizon will be treated of in another 
chapter, and a few statements will suffice for the coal. 
The group as a whole is shown with great distinctness in all the 
townships of the county, except the four following, viz., Lawrence, 
Franklin, Wayne and Sugar Creek. Even in these there are occasional 
outliers that contain good exposures of the series, but the series shows 
no economic value, so far as is known. 
The Upper Freeport horizon embraces, as will be remembered, a 
coal seam, a limestone and a clay deposit, in addition to the local ac- 
cumulation of iron ore, to which reference has just been made. Of 
these the limestone and the clay are the most persistent. The former, 
indeed, is everywhere found at its proper level, constituting the best 
known of the buff limestones of the county.
