The interval between the Upper Washington and Franklin limestones 

 is 36 feet. The section from the Dnnkard coal bed to the Upper Wash- 

 ington limestone is shown at a mile and a half above Jollytown. If the 

 limestone, Number 12, be the same with that seen at Jollytown, which 

 seems to be practically certain, the interval between the Jollytown coal 

 bed and the Jollytown limestone is 74 feet less than the interval in 

 eastern Perry, 114 feet less than ia Jefferson township. The interval 

 between the Dunkard and Nineveh coals was not obtained by direct 

 measurement; it is 172; at White Cottage, 6 miles north, in Jackson, 

 it is 127 ; but in Aleppo, 8 miles northwest, it is 200 feet. The Gilmore 

 sandstone is reached at the head of Dunkard creek, 30 feet thick and 30 

 feet above the Jackson limestone. The whole interval to the Dunkard 

 coal bed, 300 feet, is without detailed exposures. These high rocks 

 are reached on the divide between Dunkard and Pish creeks, over which 

 one crosses into Springhill township. 



Fish creek descends rapidly toward the west, so that within a mile 

 one is below the Nineveh limestone. Everything between the Gilmore 

 sandstone and that limestone is concealed in by far the greater part 

 of the township, but there are frequent exposures of lower l)eds. The 

 interval between the Nineveh limestone and Dunkard coal bed, measured 

 directly at several places, varies from 120 to 150 feet, being greatest 

 near the West Virginia border at the west. In the eastern part of the 

 township a coal bed, 1 foot 1 inch thick, is at 45 feet below the Nineveh 

 limestone and 80 feet above the Dunkard coal bed, and at 30 to 40 feet 

 lower is an impure limestone. The coal bed is probably that termed 

 Hostetter by Doctor White. Toward the west side of the township the 

 Fish Creek sandstone, overlying the Dunkard coal bed, becomes contin- 

 VLOus with a higher sandstone and extends almost to the Nineveh lime- 

 stone, replacing the other beds. The Nineveh limestone retains its 

 thickness to the western line, but becomes earthy. The JoUjiiown lime- 

 stone is rarely exposed and it seems to be quite impure. As seen at one 

 place, it is 6 feet thick and 165 feet below the Nineveh. A trace of
