THE LOWER COAL MEASURES. 299 
_ The Middle Kittanning coal is mined near the well’s mouth, but 
about 40 feet above it. On the farm of Anderson Gibbs, near by, the 
Gray or Putnam Hill limestone is found 72 feet below the above named 
coal seam, but in the next township this interval ranges from 87 to 100 
feet. In drilling the wells to which reference has been made, a blue 
limestone has been repeatedly struck, about 70 feet below the Gray 
limestone. This matches well to the Lower Mercer horizon, as found 
in the northern outcrops. The bottom of the seam in question is about 
80 feet below this last-named limestone. These facts can be combined 
and shown in tabular form as follows:

According to this scheme, the stratum in question would be not far 
from the place of the Sharon coal to the northward. The interval 
would be shorter than we should expect, but while questionable, this 
interpretation would not be entirely inadmissible. 
The actual section, as shown in the records of the Norris well, does 
not, however, match well to this scheme. The section is as follows,
