48 cent [illegible] found 17 ft 4 in below the upper part of. Spirifera Clinton horizon. I immediately overlying the fossil found Clinton are between 2 and 3 feet of light brown arenaceous lime- atone, breaking up into pieces 4 to 6 in. square a end. lm. Above this lie the Spier Osmond clayey shales. The ladder rock, between the clayey shale and the Clin- ton is perfectly the equiv- alent of the basal Niagara of Indiana sections. The total thickness of the basal Niagara and the same Osmond shale is here 38 feet 4 inches. This thickness was measured on the eastern side of the creek, where the road, after turning southward from the bridge, bends to the east. The clayey shale is best ex- posed on the eastern side of the creek half way between the turn bridge and the rail- road bridge, when the creek crosses the road. The shale 48 cent in here seem to be very clayey, is composed of fine fissile a shaly layers, and varies in color from brown to dark blue, purple, and green below. The same richly colored parts are banded with those colors. The Osmond limestone is a brown arenaceous limestone due to the weathering out of the more calcareous ingredi- eats. Its thickness is 1 foot 4 inches. It is firmly strati- fied. The fossils found in it are: Calymene Blumenbachia, pygidium + glabellum. Platyistoma Miagarense, alittle below medium or Stephanura reductidalis; Stephanura with raised beaks or flat valve and medium sized plication, as in Dayton Clinton. Spirifer Miagarensis, smooth with medium fold and sinuos. Ferestella, fine branches, com- mon.
