At Berlin village there are two coal seams, which lie, after allowing 
for considerable local dip, about 35 and 75 feet above a gray limestone. 
They have been designated Nos. 6 and 7. The upper is probably 6a if 
the lower is 6. The similarity of the section, however, to those in 
German and Walnut Creek townships (see Fig. V), raises the question 
whether these are not the Kittanning coals, 5 and 6. But as sufficient 
examination of the region has not been made to warrant a change, the 
lower seam will be discussed as No. 6. It has a sandstone roof, though 
shales sometimes intervene. The ash is purple, and there is an inconstant. 
middle parting of sulphurous matter. It is 33 inches thick, and is 
mined by Dr. P. P. Pomerine and George Hott.. Dr. Pomerine’s mine 
was sampled with the following result:
