ALLEGHENY FORMATION IN WEST VIRGINIA 133 



Pittsburg and 295 below the Ames limestone. The Brookville is at 105 

 feet lower, or 712 feet below the Pittsburg and 538 feet above the red 

 shale of the Lower Carboniferous. At Philippi, 4 miles farther south- 

 east, a boring shows the Lower Freeport at 106 feet above the Brooke 

 ville, the latter at 522 feet above the red shale. There the Lower Kit- 

 tanning is 3 feet thick and 25 feet above the Brookville. Doctor White 

 gives a combined exposure and record just below Philippi, thus :

making the interval from Upper Freeport to Brookville 140 feet and the 

 whole thickness of the Allegheny 155 feet. The relation of the Brook- 

 ville to the Pottsville is the same as at Webster and Moatsville, as well as 

 at Newburg, in Preston county, 10 or 12 miles east from Webster. The 

 Freeport sandstone overlying the Upper Kittanning is coarse and much 

 of it is pebbly. A limestone is present at a few feet above the Brook- 

 ville coal at Webster, Moatsville, Valley Furnace, and at Meriden below 

 Philippi. It was used as a flux at Valley Furnace, where it is 10 feet 

 above the coal; this is suggestive of the Putnam Hill horizon. The 

 Roaring Creek sandstone, about 60 feet thick, is continuous with the 

 lower sandstones in much of the area southward, and, forming bold 

 cliffs, makes easy the tracing of the coal bed. The Brookville (Arden, 

 Roaring Creek) coal bed retains its place at 10 to 15 feet above the 

 sandstone, constantly rising, so that near the southern border of Barbour 

 county it is 200 feet or more above the Valley river. The structure is 

 complex, there being nine layers of coal and shale, in all 14 feet thick, 

 with one bench of coal 3 feet 1 inch.* 



From this locality southward the Brookville is high up in the hills 

 and no detailed section of the rocks above it is available until one reaches 

 the Kanawha waters. The bed retains its tendency to divide and is 

 from 6 to 10 feet thick in Randolph south from Barbour. In Webster, 

 south from Randolph, it is from 5 to 7 feet thick and its top bench is
