the fossiliferous black slate stands for the Putnam Hill limestone, and 
the sandstone ledge below is in the place of the Homewood sandstone 
of the east. The main objection to this identification is the distance of 
the coal from the Ferriferous limestone. To the north and east, the 
interval between the Putnam Hill limestone and the Ferriferous (Baird 
ore) has always been found smaller, but on Monday Creek it rises to 
35 feet, and a gain of 15 feet in so considerable a distance is not outside 
of a reasonable range. 
A few facts are subjoined to show the distribution and development 
of the seam. On Section 31, Washington township, on the farm of G. 
Niman, the coal shows the structure represented below:

Another exhibition of the seam is given in the following diagram. 
These figures stand for the best of the seam, and are not known to 
represent a wide area. A seam like this is fairly mineable, if persistent. 
The quality is pronounced good :

This measure is obtained from Mr. L. Reddick’s farm, Section 
29, Washington township. The same structure and thickness are also 
shown on the Heinlein farm, Section 33, and at numerous other points 
near Mt. Pleasant, and also on Jasper Allen’s farm, Section 16. It is
