275 10) N of Berea to RR cut & stream b. Crossing 2 3/4 mi. N of Berea, The dip as shown by Dev = 33 ft. in two miles going southward. Near Berea the dark brown recrystallized rock of S.M sections, reveals the cleety Dev. This bed was not noticed at RR cut. nor was the cleaty layer near there. The RR cut is 2 1/2 mi's N of Berea. The Devonian limestone is here 5 ft thick; 20 inches above the base fish teeth are very common in the bottoms of one of the limestone layers. Fish plates are also common. 4 ft of greenish slaty clay are ex- pried below the Dev. The total thickness of this clay is believed to vary between 10 1/2 and 13 1/2 feet judging from the absence of limestone exposures at this level along the RR. 13 feet of limestone with interca- lated clay beds Section along the RR + less reliable than would be a vertical section. Differs as leads: 1 ft Limest layer with Platystrophia biforata, Streptinlynelmus, plant form corals. Relicites and shell tus. Large crinoid beads. 3 1/2 6 in reddish brown limestone in clay at top are large crinoid beads Stelf-- 1670 tubasina calyculata, Madison top at 939. 274 Near Berea 1/2 mi. N of railroad to Corrife, or l. is 8 1/2 ft thick. Near top it becomes very cleety. Towards the base it is not very sparingly cleety. Overlying the same cleaty layer at tooths is this recrystallized dark blue Dev limestone. Judging from beds dev scattered in the fields the thick- ess of this recrystallized rock nearly, is not quite, equals 5 ft. Exposures on west side of RR, north of a culvert, where a stream passes beneath a culvert. 275 bis At the RR cut 2 1/2 mi. N of Berea there is no recrystallized place by the Dev discernible; nor is there any cleaty bed. There is not a trace of crust present at mine corral? Nothing resembling the heavy cleety beds seen near Berea. The total Dev line is 5 ft thick
