resting on fireclay, not measured, to the Pottsville. The Clarion was not 

 seen in this shaft, but Mr d'Invilliers saw if at other localities 15 to 25 

 feet above the Brookville. The Gorman coal bed of the southern counties 

 appears occasionally. The Upper Freeport consists of Bony coal 4 to 8 

 inches and 5 feet of good coal, with midway a slate 2 to 3 inches thick ; 

 but the Upper Kittanning, roofed by 2 feet of slaty cannel, is the more 

 important bed, being available in a larger area. A long narrow strip of 

 Allegheny occupies the easterly division of the basin in the southeast 

 part of the county, where the Lower Freeport, worthless in Snowshoe, is 

 worked and has this structure : 



Feet. Inches 



Bone coal 2 to 4 



Coal 6 to 12 



Cannel 2 to 3 



Coal 4 to 5 



and sometimes a thin streak of cannel in the main coal. Xo limestone 

 was seen in any portion of this area.* 



In Clearfield county one has Doctor Chance's partial section at Morris- 

 dale, about 12 miles southwest from Snowshoe and on the westerly side 

 of the basin. The Lower Freeport and Johnstown Cement limestones 

 are here. The coal bed identified with the Upper Freeport is insignifi- 

 cant, but that taken to be the Lower Freeport is important and has the 

 exact structure of the Upper Freeport at Snowshoe, thus :

Bone 2 to 8 



Coal 3 to 2 C 



Slate 1 to 2 



Coal 1 3 to 2
