Laona sandstone in a field quarry 50 rods north; also in a small quarry 5 miles southwest from Brocton near the lake road, in the sides of a small ravine and in a quarry similarly situated 1 mile farther southwest. The sandstones in this horizon are constantly thinner bedded and less compact in the exposures southwest from Forestville, and they appear in the Portland gray conlfretlon^and uPPer part of the cliffs on the lake shore northeast from Barcelona (Port- land Harbor) as a band of flags and thin sandstones and disappear under the waters of Lake Erie about a mile southwest from the mouth of Chautau- qua creek and 9 miles northeast from the Pennsylvania line. The sandstones of the Shumla horizon are exposed in the sides of Chautauqua creek ravine in the village of Westfield near the milldam, and in the cliffs along the lake shore from 1% to 3 miles north of the state line, and they come down to the lake level under the gravelly beach y-2 mile north of the state line. Fossils of any description are exceed- ingly rare in the shales and flags be- tween the horizons of the Laona and the Shumla sandstones along the lake Cashaqua shale Middlesex shale shore, the onlv ones found being a few Dunkirk black shale Silver Creek light soft shales Angola soft shales with concretions Rhinestreet black shale Bfi= sj Genesee shale Fig. 13 Section on Lake Erie from top of Hamilton to top of Laona sandstone. Stations 50- 64 small brachiopods in the intermediate beds on Chautauqua creek and in about the same horizon in the bed of a small creek that flows into the lake near a fishing station 4 miles southwest from Westfield. At Northeast Pa. Chemung brachiopods were found in small calcareous masses on the uneven upper side of a 4 inch flag and on the lower surface of a similar flag 5 feet higher, both of which are exposed in the bed of Twelve Mile creek, % mile from the lake and abo
