The Laurel limestone here is 9 ft 2 in. thick and is directly overlaid by Black Shale, nor Crn- ciferus being visible. 119 About half a mile further less, a high bluff partly concealed by the woods, shows the Black Shale- Cruciferous contact at 890. Nor Cruciferous is exposed. The Laurel limestone here is 16 feet thick. The Upper Ozgood clay is 1ft 6 in thick and the Ozgood limestone is 1 ft 8 in thick. 93 The top of the Lower Silurian is estimated at 835 118 L8 840. A quarter of a mile further the road crosses Rolling Fork, and a little over a mile westward connects with another road. In the south east angle of the road the bottom of the Black Shale is seen at 875. Nor Cruf. nous is exposed. The Lau- rel limestone is 4 ft 8 in. thick. The Upper Ozgood clay is 2 ft 4 in. thick. The Os- good limestone is 1-1½ feet t thick. The top of the Lower Silurian is calculated at 840 feet. A little over a mile and a half, northwestward, a short distance after crossing Rolling Fork westwards the north, the bottom of the Black Shale is seen at 875. Nor Cruciferous is 2m The Laurel limestone are is 7 ft 6 in thick. The top of the Lower Silurian is calculated to be about 840.
