furnish the best clay of this whole district, the clay being hauled for 
long distances to the Muskingum county potteries. The seam of clay 
is 5 feet thick. On the D. Crossen farm, Section 27, the clay is said to 
assume its hard and non-plastic condition, but there are not any open- 
ings to it at present. 
On the Chilcote farm, now A. E. Henderson’s, Section 27, both the 
coals are worked, on a large scale, for country banks. The Middle Kit- 
tanning or upper seam has been mined for many years to supply fuel to. 
a considerable scope of country to the westward. The quality of the 
coal is good, and the seam is of full thickness. Its structure and 
dimensions are shown in the appended figure:

The lower seam has also been worked here to a considerable extent.. 
It measures 4 feet 6 inches in thickness, and shows no partings. It is 
counted equal in value to the upper seam. Its structure is shown in
