The upper [illegible] consist of a dark lamin rick, The Coniferous is overlaid by Black Shale. 124 cont. 10. Continued- layers of clint 2-3 inches thick intercal- ulated. at the locality here de- scribed, there are 10 feet 6in. of Clint or exposed. About 11 feet are not exposed. About 8 feet of this proba- bly consisted of Lower Osgood shale, and the remainder of the grey crinoidal Conifer- ous. About 15 inches of this grey Coniferous are actually exposed. 12 inches of dark lamin Coniferous lie above. Above this lies the Black Shale. 13. 123 About two thirds of a mile west of Raywick on the road to Gleamings and Howard town, just before reaching Prather Creek, the top of the Lower Silurian is exposed at 840. This is overlaid by 8 ft. 4 in. of Clinton, and this in turn by Lower Os- good clay. 122 840- ? Less than half a mile beyond Prather Creek, the top of the Osgood Clay is seen at 863. The thickness of the Osgood beds is not known here and therefore the level of the top of the Lower Silurian can not be definitely ascertained but it is estimated at 840 or less. On the Osgood Clay rests # 8 ft of grey crinoidal Coniferous and 8 inches of dark fine grained limestone. Above this is Black Shale. 121.- Nearly a mile beyond Pra- ther Creek, the road to Glean- ings turns off southward and within two thirds of a mile, elicits the north- nern bank of Rolling Fork. The top of the Lower Silu- rion is here at 840, and is formed by 1 foot of hard rock overlying the Madis- Son bed. The Clinton is 7 feet thick. Over it lies the Osgood clay. See next section.
