Near the middle of the Trenton, at the footfalls of Rocky Brook we again saw distinct beds, but far or thay at Taylor Tally. Late along with large Orthoceras, Trachymera, Raphistoma. Hydra appear rarely Cyclaspis fisulenta. Labor thought down the Frankfurt by Orthos reminding of O. gracile. Onerosus reams rough In the afternoon rode about four miles east to Weststone brook to see the Utica and the higher Cincinnati series. The Utica is the normal Haell shale with some large Treachters feeli n large specimens. Endromus juteiforme is abundant. Inaptiles are rarely seen and other forms. These Haell shales fans into green gritty sandy shales that hidden of introduce more and more thin sandstones (from 1/2 to 2 inches thick) and more thinner than is a persistent sandstone some, all in shale. nearly thin sandy limestone in the latter abound in Bygon dolmanella, or large Plectan trills, rarely Ru- also Contrita. And two Phragma alternata, Gygopina cincinnatensis. In the thin sandstones the same forms occur but more often Dolmanella, Plectan trills, Byssomychia radiata, Orditepisis modistaris and other smaller forms. Also saw little Cornulites (always simple) or Tentaculits. Saw me Scrovinus subcrassus and jukely Eotemronius. Splytremains columnals are
