resting on the Pocono sandstone, 215 feet. We have here the upper 

 shales, 165 feet ; the upper hmestone, 140 feet ; the " Pencil," 5 feet ; the 

 silicious limestone, 85 feet, and the lower shale, 50 feet ; in all, the lime- 

 stone is 230 feet. Comparing this with the measurements on Rich moun- 

 tain by Taft and Brooks, one observes a decrease in the shales from 600 

 to 165 feet, which is what might be expected, since Mr Darton gives 

 1,250 feet for the shales farther east in Pendleton county. The lime- 

 stone has decreased, though not to the same extent, there being, accord- 

 ing to Messrs Taft and Brooks, 850 feet in Rich mountain. If Stevenson's 

 figures for Rich mountain be accepted, the decrease in the limestone 

 would be comparable with that in the shale. From what has been 

 learned of conditions in the western counties, it is probable that the de- 

 crease is mainly in the upper limestone, for thus far the silicious lime- 

 stone tends to hold its own. At this locality one is on the east side of 

 the Chestnut Hill anticlinal, which has become so gentle that it is 

 crossed b}^ the Pittsburg coal bed. The section may be compared with 

 that obtained by Doctor White under this axis on Cheat river. There 

 the shales are 299 feet and the limestone 140 feet, including the silicious 

 limestone; the shale has decreased, while the limestone has increased. 



With this Lewis record may be compared that of a well drilled near 

 Sutton, in Braxton county, about 35 miles southwest of the last and 

 about an equal distance northwest from the Stamping Creek locality in 

 Pocahontas county. It is very nearly on the strike with the well in 

 Lewis county. The succession is
