BULLETIN OF THE LABORATORIES 
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 fossiliferous zone of the Waverly. 
Near Summit on the Baltimore and Ohio R. R., we find the follow- 
ing section : 
6. Shaly freestone 10-15 ft. 
5. Blue shale 4 ft. 
4. Grey calcarous sandstones 12 in. 
3. Blue shale 10 ft. 
2. Unexposed 70 ft. 
I. 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 too ft. 
Best exposed at Bald Hill and i mile north of Newark. 
13- 
Shales, soft, with few small fossils.

All below congl. I. is spoken of as division I, la being that portion of this 
division over 40 feet below this zone, Ib the upper 40 feet. Division II includes 
all between congl. I and II, and division III, the remainder.
