line to the most easterly exposure of its place. The Upper Washington is 

 270 feet above the Washington coal bed at Waynesburg, and an almost 

 direct measurement by Doctor White in Jefferson 6 or 7 miles east makes 

 the interval 254 feet. The Franklin limestone is always present at 30 

 to 35 feet above the JoUytown coal bed, which rarely exceeds 1 foot, 

 but is always present. The Middle Washington limestone is absent, 

 but the Blacksville and Lower Washington persist, though they rarely 

 are more than 3 feet thick. The Waynesburg A and B coal beds seem 

 to be continuous and the Colvin limestone is prominent. The Wa3mes- 

 burg sandstone, shown in Franklin and Jefferson and thence eastward 

 to the Monongahela river, is sometimes 75 feet thick, more or less 

 shaly or flaggy above, but massive and at times is slightly conglomerate 

 below. The Cassville shale, carrying no limestone, is somewhat irregu- 

 lar in occurrence, but at several places is rich in plant impressions. The 

 interval between the Washington and Waynesburg coal beds is 173 

 feet in eastern Franklin, and the greatest interval is 180 feet on the 

 eastern edge of the county. 



Washington and Morgan townships are north from Franklin, on the 

 Washington coimty border. The Middle Washington was seen in the 

 former at 98 feet below the Upper Washington, and a thin coal bed, 

 perhaps at the JoUytown horizon, is at 83 feet below the latter limestone. 

 A direct measurement between the Nineveh and Upper Washington lime- 

 stones in Morgan gives 180 feet. This is 2 miles south from Ten-mile 

 village, in Amwell of Washington county, and the Nineveh limestone 

 was seen at many places along the northern border where there is a coal 

 bed at 50 feet below it. A dark limestone, probably the Ten-mile, is 

 40 feet above the Upper Washington, and the Boyd coal bed, 30 inches 

 thick, 15 feet above the Upper Washington, is mined on Boyd run, in 

 Washington township. The Franklin limestone and the JoUytown coal 

 bed persist, but the Washington coal bed and the other limestones are 

 insignificant. The Waytesburg A and B and the Colvin limestone arc 

 here and the Washington coal bed is 160 feet above the Waynesburg.* 



The southern townships from the Monongahela river westward along 

 the West Virginia border are Dunkard, Perry, AVayne, Gilmore, and 

 Springhill. In the first the exposed section reaches to little above the 

 Washington A coal bed, which is very thin. The Waynesburg sandstone 

 is prominent and at many exposures' rests on the Waynesburg coal, but oc- 

 casionally the Cassville shale, carrying no limestone, is present, 3 to 7 

 feet thick and crowded in the lower portion with fine impressions of
