The Clinton is overlaid by 1ft of rotten basal Niagara, and above this are 16 feet of very typical Lower Osgood clay shale, 16 feet thick. Along the road the rocks dip strongly northward; south of the road they dip south- ward \ , and the trough of the synclinal dips west- ward so much that at the top of the hill eastward there is no Clinton or Os- good shale exposed. Towards the west the trough must dip eastward since here the Clinton is found high up in the hill. Owing to the trough the Osgood clay was preserved here. It is not seen for miles west- ward.
West of the creek at Wheat- ley's, the top of the Colum- baria bed is seen at 1240.
East of the creek it is seen at 1170. This is probably due to the trough formation above mentioned. About

About 2 miles west of Wheat- ley's Branch, 1/2 mile east of Mc Intire's store, the fol- lowing Clinton fossils are found in fine Clinton clay:
The Clinton probably runs just along the road level.
Oterinea luiza
Artus bifurcata
Artus elegantula
Artus flabella
Strophomena patenta.
Clinton level at 1260.

The Clinton - Lower Silurian junction is here at 1262.
The Clinton is 7 feet thick.
The Lower Osgood Clay is 4½ ft thick. It is immediately over- laid by a great abundance of weathered cherty Orvis ferns fragments. The Clinton con- tains Artus flabella.
