This point is about 3 mile above the mouth of King’s Creek. The 
Roger coal is worked at many points in this valley, and is quite widely 
known as the King’s Creek coal. It can be traced on every farm. 
At the Tarr Brothers’ farm, 2 miles above the mouth of the creek, 
the following satisfactory section was found:

The Lower Freeport limestone is also shown at intervals along the 
creek. The coal ranges from 3 ft. 6 in. to 5 ft. Its structure, as given 
above, is modified somewhat in different mines. A mine, ¢ mile below 
the Tarr Brothers’ mine, shows the following structure: |
