2nd day. - Stop 1. Looked for cephs. Fragment of baculite given me by Drake. He also mentioned a Maryland locality with abundant Sphenodiscus with shell material. Collected only the Choristothyris as we have ample of other stuff. Stop 2. Here the 'black' Red Bank- overlies Navesink. Coll. from Shell bed in Navesink - big Exogyres and Gyppeccs, Belamnitella and others. Kept a large Exo for forums in its fill. The fossils are packed amazingly, one set within the other. Mithed valves very rare. Some phosphatic nodules in this section near the supposed Navesink-Red Bank contact. Lower Red Bank? Stop 3. Harwoodtown - Triton contact. Sphenodiscus found in darker glauconitic Sand of T.R.B. - which resembles the Red Bank, Critical locality which demonstrates that spheno-bearing beds - presumably Triton but could be Red Banks - continue S. of New Egypt. The Rickards-Stzlc Geologist school holds to old belief that these do not occur south of New Egypt.
