8'8 J. J. STEVENSON CARBONIFEROUS OF APPALACHIAN BASIN 



Here one is 18 miles southeast from Pine grove, in Wetzel county. 

 The Uniontown coal bed is almost 268 feet above the Pittsburg. At 

 Browns the interval is 265, and at Cherry Camp 287 feet. The top of 

 the Gilboy sandstone at Browns is 385, at Cherry Camp about 400, and 

 at Sedalia 371 feet above the Pittsburg. At Sedalia there is a little 

 black shale at 388, and at Browns the Waynesburg coal bed is at 400, 

 underlying a sandstone which at Salem is 405 feet above the Pittsburg. 

 The elements of the section are the same throughout and the varying 

 intervals are but sums of variations in the subordinate intervals. The 

 great sandstone at Sedalia is the Gilboy of earlier records, increased 

 downward so as to embrace most of the underlying shale at Browns. The 

 interval decreases westwardly, and at 10 miles from Sedalia the Union- 

 town is 250 feet above the Pittsburg, with no coal in 168 feet above to 

 the top of the well. The Waynesburg is evidently gone, as no trace of 

 it appears in intervening records. Here one is on the border of T}der 

 county and about 11 miles southwest from Smithfield, in Wetzel, where 

 the Waynesburg is present, and 350 feet above the Pittsburg. 



Long run, on the Baltimore and Ohio railroad, is 7 miles west from 

 Cherry Camp. A well record gives the Pittsburg as 3 feet thick, but 

 no clear record is given above that coal bed. Along the railroad from 

 Long run westward to West Union, midway in the county, one often 

 sees a coal bed underlying a massive pebbly sandstone. The structure 

 of the bed is remarkably like that of the Waynesburg farther north, and 

 for that reason Stevenson correlated it with that bed, regarding the over- 

 lying plant shales as equivalent to those now known as the Cassville. 

 The section at Smithton is :

The material here available may not suffice to justify positive correla- 

 tion of this bed, but it can hardly be the Waynesburg, for that bed seems 

 not to extend so far south, while the conditions at Long run and in 

 counties beyond seem to justify the assertion that it must be very near 

 the place of the Uniontown, as Doctor White has suggested. Its re- 

 semblance in structure to the Uniontown of Monroe coujity, Ohio, is 

 very remarkable. Detailed records are too few in Doddridge county to
