lain with a heavy bed of blackband ore. The area is small, and coal 
and ore were worked out of it a number of years ago. On the Gibler 
farm adjoining, and also on the Samuel Creighton farm, the blackband 
- has been opened and worked quite largely. On the Rhinehart land the 
section is as follows:

The elevation above Lake Erie assigned to the Upper Freeport 
coal is slightly in excess of the true measure, as the coal seam which we 
use as a base has been carried downwards somewhat by the dip, before 
it comes to be used in the new section, but the true elevation is not 
less than 590 feet above Lake Erie. 
On the Rhinehart farm, the distance from the Middle Kittanning 
coal (No. 6 of Tuscarawas) to the Upper Freeport coal is 130 feet. On 
the Creighton farm, the same interval measures 142 feet.! 
The Upper Freeport limestone is found at points without number 
at this same general elevation. It is frequently burned into lime for 
local supply. 
The Lower Freeport sandstone, No. 7 of the previous section, be- 
comes an element of great importance in all of this part of the country. 
It is quite coarse, and at times even conglomeritic throughout Stark, 
Tuscarawas, Holmes, and Coshocton counties, and this fact has helped 
to the wrong identification of it with the Mahoning sandstone. The 
latter stratum is also distinctly conglomeritic throughout this same 
region. Where the Lower Freeport sandstone has been counted the 
Mahoning, it has been found necessary to give a new name to the true 
‘Mahoning sandstone. This is called the Stillwater sandstone in the 
valley of the same name. ‘The fact that the true Mahoning sandstone 
is more decidedly a conglomerate than the Lower Freeport sandstone, is 
remarked by Newberry in vol. II, p. 153.
