In the stream bed south of the hill, and along the north western lens of the hill the densely fossiliferous Cincin- nati &mp shaly limestones (Pulham beds) are well exposed. Thickness probably 30 feet. The Columnaria bed and the Madison beds were not present. A small thickness of thin arenaceous shaly limestone, evenly bedded, is exposed, north east of the hill, east of the stream. Its geological loci- gic is unknown but I am inclined to regard it as the beginning of the following period. Thickness possibly 6ft. About 100 feet south of the Last Cincinnati Group by- passes on the west side of the hill and also at a point near the fence, east of the creek near the house, are exposures of a brownish arenaceous limestone rock which contains numerous small fragments of fossil shells. A well preserved valve of Orthus bifurcatus with about 5 articulations in the me- dian fold was seen in the same west of the hill, and a less perfect fragment of the same shell was seen east of the creek. At both ex- pasures, fish remains occur. This suggests erosion of rock down to Richmond beds previous to deposition of presumably Devonian rocks. Thickness 13 in. Not continuous exposure of similar rocks, west of hill - 9 feet. Along the south west side of the hill and also east of the stream, a dark blue rock forming massive even bedded layers was once quarried. It has a very archaeaus appearance and very irreg- ular crumpled folding planes lined occasionally with concentrically quartz masses may through the ex- posed surfaces of the rock in the quarried faces
