"Washington, D.C. Dec. 31-1929 Tuesday Spent the morning at the U.S.G.S., mostly with Mr. Jonas, and some with Strze. Talked general stratigraphy around the Taconic Disturbance. Strze has my fossils in the Juniata, but in the white Tusca- nora about 70 above base he has Artinoglypheus. In the Martinistry not far below the Tuscarora contact he has others with the deep kies grapholiths, Pyllographus, Te- tropagaphus etc., about 10 species. Higher come the Chor- marshfield grapholiths and the regular Martinistry into Eden and the Maysville faunas. Follows Illinois in that the Juniata = Queenston = Pi-Richmondian. As the Juniata goes further east, into the Tuscarora - Medina the former cannot be late Ordovician < Richmondian. Had lunch with Mr. Jonas and then back to Brandman Hotel and at 3 o'clock I start for St. Augustine Florida. It is the Miamician along the Atlantic coast to Miami, Florida. A soft balmy day.
