180 J. J. STEVENSON CARBONIFEROUS OF APPALACHIAN BASIN 



in all, 615 feet ; but before discussing further the relations of these beds 

 it will be wise to take up another line, beginning at Charleston, in the 

 Kanawha, and meeting at Philippi, in central Barbour, the one followed 

 thus far.* 



Doctor White has given a practically complete section at Charleston, 

 extending from the Pittsburg coal bed to the Lower Carboniferous. The 

 portion below the Stockton coal has been quoted already ; it is necessary 

 only to give the portion above, and then to summarize the whole. Con- 

 densed, it is

The interval from the Pittsburg to the sandstone, number 5, is 566 feet, 

 and to the Mason coal bed 651 feet. Numbers 5 to 8 are the Charleston 

 sandstone of Campbell, here very much thicker than at Huntingdon, 

 The interval between the Mason and Stockton is 147 feet in this section, 

 but at a little way farther up the Kanawha it is somewhat greater. The 

 number 5 Block coal bed is from 40 to 65 feet above the Stockton, and 

 usually a thin coal bed rests on the Flint. If Doctor White's suggestion 

 be accepted and the Mason be taken as the Upper Freeport of Penn- 

 sylvania, the division of the column would be

The subdivision is only approximate for Allegheny and Pottsville, 

 but it may be taken tentatively for the study. In tracing the section 

 the Stockton will be used as the key-bed. At Charleston the thickness 

 from Stockton to Lower Carboniferous is about 1,150 feet, almost equally 

 divided between Kanawha and Lower Pottsville. The Campbells Creek
