July 18th Thursday. Trifles easy and write letters. Left Martinsburg at 3.17 and arriving at Cumberland at 9. Stopping at Sandons. Noble and Reeds at Mrs. Roberts, July 19th Friday. Cumberland, Md. Collected all morning up to 1.30 at East Valley. The section begins in the lower Martins shales and some limestone [illegible] about 75 feet thick. The fossils collected are amalgam for the upper ten feet, a few are marked as from lower layers, there are from about the middle.) Then follows a series of heavy bedded limestone with some Charnia for 30 feet. One limestone of the same nature contains for 25 feet abundantly in Favosites & Phyphyllum and Stromatolites. All of these beds are Martinsburg. Apparently nothing 30 feet thick Above is coral gone but Reeds and Noble found it of the field and rejected an area across limestone with sandstone. Can not determine the origin. In talking to Gordon of this horizon he thinks it should go with the Ordovician, above has some [illegible], Then follows the Lower Ordovician.
