Saturday June 11-1910 Dunham Rained hard all morning. In the afternoon visited the eastern quarries from Barnie's in the south to the Drip quarry at the north. Collected in the upper five feet of the Transition Series to the Creymans having Sphinctula solcata (go through the 13 foot) In these five feet got L. alve, L. crunucensis, Tc sycacanthus, Phtherodonta variistriata, the small Alphichonella described by Barham, Plocdenia and Plocdenella pennsylvanica, Beyartmia. It seems to me that these are the beds or about the beds in which I collected the crinoids at Litchfield. In the quarries just east of the village and a little north of the cemetery one sees the following succession: Creymans a cattle thin layered heavy textured grey limestone that does not weather into clumps on the beds. The 12 feet of dark blue to black marl a less irregular trilobed limestone holding at the top the fossils mentioned above. Then the Tataraculite series or Charlevoix. At the top 30 and thick, followed by 7 feet (in 3 layers) that will weather into thin beds, then 8 feet of beds in 4 to 6 inch layers followed by one foot of this plate clots abounding in Tetraculites. Then a heavy bed, 3 feet thick followed by a dark clayey layer also from the mud on the base of the quarry, about 3/10" thick
