276 11. RR cut 2 mi. S. of White's Station. Black shale. 3 in. Dev. blue argillaceous gritty limestone with fish teeth. 3 ft. limestone with shaly partings. 10 in. blue shale. 7 ft. 6 in. limestone with shaly partings. 2 ft. 8 in. blue shale, 1 ft 4 in. more solid layer with Orinid leads + Mint fields. 3 ft. limestone with shaly partings. 12ft. 6 in. Base of upper beds with only a few large crinoid leads, landing dry from to 3 ft. more fluid limestone with shaly partings. 4 ft 4 in. massive layer at base. Madison beds, only 2 feet exposed near RR, more in field NE of RR cut. Dip of rock is southward, hence Madison appears in field above the level of base of Clinton in RR cut. 277. On Kingston and Boone Gap Turnpike. Berea 1000 ft. Base of Black shale 952 feet above. 1 mile N. of centre of Berea, in thin bed. Lingula is common near base of Black shale, in the stream bed according to Fischer. 4 in. chert with cup crags, radiating, same as S. of Lebanon; 3/4 coral. 8 ft. Dev. limestone, Upper part with large characteristic crinoid stems. 278. The greenish blue clay shale underlying the Corniferous is not well exposed in previous section. About 2 1/4 miles N.E. of Berea, where Joe's Lick Fork crosses the pike, an exposure can be seen by mile west of the road, south of the fork, east of Bever Terrell's house. Here about 13 feet of blue clayy shale underlies the Devonian limestone. A large reddish brown limestone with calcite crystal and nodules is assumed to belong to the upper part of the Clinton, Primory dolomite line modelled out from in P.
