SYNONYMY 207 



southern Anthracite fields of Pennsylvania, but 

 does not extend into other parts of that state or 

 into northern West Virginia. 



Sewanee coal bed Wanting in Ohio, in Pennsylvania, except southern 



(J. M. Safford.) and middle Anthracite fields, and in most of West 



Virginia north from the Kanawha; wanting in 

 northern Kentucky, but present in southern Ken- 

 tucky, where it is probably the Main of Lesley ; 

 Main Sewanee of Safford, Coal Creek, Harriman, 

 Rockwood, etcetera, of authors in Tennessee; 

 present but not mined or named in northern Ala- 

 bama ; Sewell in Kanawha region of West Virginia. 



Bonair sandstone Wanting in Pennsylvania bituminous areas, in north- 



(M. R. Campbell.) era West Virginia, in Ohio, in most of Kentucky; 



Bonair of Campbell, Main of Safford in Tennessee ; 

 Upper Conglomerate of McCalley, Second Con- 

 glomerate of Gibson in Alabama ; Raleigh of Camp- 

 bell in West Virginia. 



Cas hie coal bed Wanting in Pennsylvania bituminous, in most of 



(A. M. Gibson.) northern West Virginia, in Ohio, in Kentucky ; not 



named in most of Tennessee ; Sewanee of Colton 

 in southern Tennessee and of McCalley in Ala- 

 bama; is very near place of Campbell's Beckley 

 coal in southern West Virginia; a still lower bed 

 in Tennessee and Alabama is at the place of Fon- 

 taine's Quinnimont. 



Etna sandstone On west side of basin extends northward only to 



(J. M. Safford.) middle of Tennessee, on east side to probably 50 



miles north from New river in West Virginia ; Cliff 

 sandstone and Lower Etna conglomerate of Safford 

 in Tennessee ; Cliff sandstone and Millstone grit of 

 McCalley in Alabama; probably the sandstone 

 underlying Quinnimont coal bed in southern West 

 Virginia. 



Etna coal bed On west side extends northward only to middle of 



(J. M. Safford.) Tennessee; represented in West Virginia south 



from New river by one of the Clark formation beds ; 

 Cliff, Main Etna of Safford in Tennessee ; Castle- 

 rock of Georgia ; Cliff of Alabama. 



Lower horizons of much importance are present along the eastern line 

 of outcrop in Tennessee and the Virginias northward to New river, but 

 one may not attempt to make correlations, as the sections in most of 

 Tennessee and Virginia are somewhat indefinite and details are prac- 

 ticall} 7, wanting until one reaches West Virginia. Here belongs the 

 " Pocahontas" coal bed, which is followed without difficulty for more 

 than 75 miles in Virginia and West Virginia.
