part of the township, where the Washington, 190 feet above the Union- 

 town, is double and 2 feet 3 inches, including a clay parting of 3 inches. 

 In the extreme southern part of the county, on the river and about 

 2 miles west from Sistersville, in West Virginia, the interval is still 190 

 feet and only a trace of the Waynesburg A remains. A massive sand- 

 stone overlies Waynesburg A and underlies 35 feet of red shale.* 



On the western border of Washington county, south from Monroe, 

 the Waynesburg sandstone, 240 feet above the Pittsburg coal bed and 

 30 to 50 feet thick, is 40 to 60 feet above the Uniontown (Hobson) coal 

 bed. In Decatur township this sandstone overlies a trace of the Waynes- 

 burg coal, and in Fairchild there is an impure limestone at 10 feet above 

 it. Along the northern border of the county Professor Andrews's sec- 

 tions extend to only a few feet above the Uniontown coal, except in 

 one case, where a limestone in red shale is noted at 91 feet above the 

 Waynesburg coal, which is 147 feet above the Upper Sewickley. This is 

 the red sometimes found under the Washington coal. In Liberty town- 

 ship, about 14 miles west from the Ohio river, Mr Minshall measured

The interval, Uniontown to Washington, is 160 feet, 10 feet less than 

 in Center of Monroe, 16 miles north, and 30 feet less than at Baresville, 

 while that between Washington and Jollytown is only 9 feet less than 

 at Baresville, 14 miles northeast. On the Ohio river about 2 miles 

 south from the Monroe county line and almost due east from Mr Min- 

 shall's section, Professor Andrews found
