rock, and the Upper Freeport coal is mined extensively at Armstrong’s 
on the railroad. Above the Armstrong coal (No. 6 of Newberry) an- 
other seam is found, 3 feet in thickness, and of good quality, but under 
too light cover to be worked to advantage. The interval is not more 
than 12 feet at this place, and probably less. Being the next seam above 
No. 6 in this neighborhood, it is designated coal No. 7, but it is scarcely 
probable that it is the equivalent of the Brush Creek coal of Pennsyl- 
vania, which is the true extension of Newberry’s No. 7. 
These facts are represented in Fig. XII.
