Here the Stockton coal bed is 728 feet below the Pittsburg coal bed. 

 Traces of coal were found at 75 and 180 feet below the Stockton ; that 

 at 180 feet answers to the bed at 142 in the boring northwest from 

 Philippi, for the interval to the first coal below has increased 35 feet. 

 The horizon of the Campbells Creek coal is not reached, as it lies beneath 

 the great sandstone. 



Not far from the line of Webster the section changes, and a new series 

 of coal beds comes in between the sandstone overlying the Stockton and 

 the Pottsville, for at Valley Falls, 6 or 8 miles north from Webster, several 

 coal beds are shown, which are practically continuous thence to the 

 Pennsylvania line. A complete section at Morgantown, about 8 miles 

 from the state line, is given by Doctor White. From the Pittsburg coal 

 bed to the Upper Freeport coal is exposed ; from that below to the Potts- 

 ville sandstone was obtained by measuring a diamond-drill core ; the 

 Pottsville is exposed.* The Conemaugh is much thinner here.
