August 7 continued The tide was unusually low this morning and one could easily walk across the rocky bar uniting Mt Joli and Pierce Rock. Cooper made it as 150 feet across. To the E of Mt Joli he saw 135' more of the same Mt. Joli formation, that is all covered by high tide. To the Pierce Rock series must be added about 200-225' feet more distal aug. At low tide this morning Cooper collected some fossils in the "Dipterus" beds beside the Pierce cove. The strike is N.40 W., dip 55 S.E. This is at or near the strike of Mt Joli and Cape Barre beds. I think he has Spirifer eminens but appears to have fewer plications. These fossils are Helderbergian. The crasis are the same as occur at the base of the Joli series. asked and Cecil Kindle showed us a very large Stormotoma (about 7 or 8 inches lay) he collected in the Richmondian of the gorge visited yesterday. He also had Catagysa leadi from another locality than he one on the mountain road.
