ly is here reached 120 feet below the last mentioned zone. As the 

 southern element in the dip is here quite appreciable, it would be an 

 ample allowance to estimate this horizon at 150 feet below the last 

 named, or 320 feet below the lowest fo.ssiliferous zone of the Waverly. 

 Near Summit on the Baltimore and Ohio R. R., we find the follow- 

 ing section : 



6. 



Shaly freestone 10-15 ^^' 



Blue shale 4 ft. 



Grey calcarous sandstones 12 in. 



Blue shale lo ft. 



Unexposed 70 ft. 



Black "Ohio" shale 30ft. 



The entire unfossiliferous part of the Waverly may therefore be 

 estimated at less than 350 feet, and the Waverly series in Licking Co. 

 at less than 570 feet. Probably 550 feet would about cover it. 



A generalized section of the Waverly in Licking Co. is as follows: 



Carboniterous conglomerate. 



14. Upper Waverly, shales and flags with few fos- 

 sils. Phillipsia meramacensis, Productus arcu- 

 atus. Prod, semireticulatus, Aviculopecten sp., 



etc about 100 ft. 



Best exposed at Bald Hill and i mile north of Newark. 



13. Shales, soft, with few small fossils 



12. Conglomerate II. Spirifer Winchelli 



II. Shale, " Allorisma layer," Spirophyton 



10. Freestone (Berea?) many fossils . 



9. Shales, barren 



8. Conglomerate I 



7. Shale " Lamellibranch layer" 



6. vShales, same fauna, less prolific 



Flags 



5. Shales, barren 



4. Flags, with Rhynchonella sappho, Leiopte- 



ria ortoni, Strebloteria media, etc 



3. Shales, bairen 



2. Shales, with Spirifer marionensis 



I. Shales, barren, "j 



Flags and black I about 350 ft. 



bituminous shale j 

 Black shale. 

 All below congl. I. is spoken of as division I, la being that portion of this 

 division over 40 feet below this zone, lb the upper 40 feet. Division II includes 

 all between congl. I and II, and division III, the remainder.
