in its bituminous portion, but the cannel block is also taken down in 
the entries. The coal lies on an uneven floor, the hills rising fully 20 
feet above the swamps. The quality is not high, and mining has not 
been carried on with any great profit. 
The seam is found here 29 feet below the grade of the railroad, 
and it does not rise to day again until the westward sweep of the valley 
of the Middle Fork brings it just above the water between Robbins’s 
and New Lisbon. Another seam is due above it throughout a consider- 
able part of the territory already traversed, viz., the Lower Kittanning 
coal. Its place is 30 to 50 feet above the Canfield cannel seam. It is 
not known on this line north of Green Station, where it is found 15 feet 
above the railroad. This seam has hitherto been mistaken for the Can- 
field seam, which is always in its own place below the Kittanning coal. 
In other words, we have two seams of mineable coal south of Green 
Station, where, according to the system of naming the coals above 
referred to, only one is due. When the Kittanning coal receives the 
designation of No. 4, the Clarion coal has been styled No. 3, but why 
it should not have been called No. 3a is not apparent. The valuable 
section found at Walters’s mine, on the south line of Green township, 
has already been given (see page 33). At this point both the Lower 
Kittanning and Clarion coals have been worked together. 
The coal of the west side of Beaver township is certainly the Upper 
Clarion seam. The registers of two borings, cited by Newberry in 
vol. III, pp. 808-9, prove very interesting. They are as follows:
