170 J. J. STEVENSON — CARBONIFEROUS OF APPALACHIAN BASIN 



The measurement number 20 was obtained in a boring. Number 2 

 is identified by Doctor White with the Winnifrede. It is in 4 thin 

 benches separated by shale, and the coal is mostly splint. The War- 

 field bed is clearly taken by him to be the Campbells Creek, and the 

 suggestion is made that the limestone number 12 may represent the 

 Campbells Creek limestone. The interval here between the Campbells 

 Creek and Winnifrede is 246 feet ; in Logan it is 300. These are coals 

 1 and 3 of the Kentucky column, which in an earlier part of this paper 

 have been identified with the Sharon and Mercer horizons of Ohio and 

 Pennsylvania. A well record on the West Virginia side of the river 

 shows the Eagle coal bed at about 100 feet below the Campbells Creek 

 (Warfield) coal bed and 320 feet above the Nuttall (Sharon) sandstone, 

 evidencing a remarkable uniformity of conditions over a great area. 

 The Lower Pottsville is but 378 feet to the first red beds, about one-fourth 

 of the thickness in Fayette county, 60 miles eastward. 



Dingess, in Mingo county, of West Virginia, is about 10 miles south 

 of east from Warfield. There Doctor White combined the exposed sec- 

 tion with a well record as follows : *

 thick, and its section may be compared with that obtained opposite 

 Warfield
