Nearly two miles westward, a road turns off to the left, and a short distance fur- ther on the Raywick pike the top of the Lower Silu- nion is seen at 938. The Upper part of the Lower Silurian is difficult to dis- tinguish from the Clinton but it does not cut dire- ctly. On the contrary masses of crystalline calcite are not in carbon and some of them seem to have replaced Tetra- dinum specimens. See S.L. Directly in the Black Shale lie 2 ft 8 inches of Columnaria. The lower grey crinoidal Coniferous is 2 ft thick.
