Sunday June 12-1910 Shore's Care in the afternoon. Drive 3 miles from Johnshaws to Shore's Care Cement works. Great quarries here in the Marlins and Coegmans. The latter is here all 135 feet thick. At the top beds become thick bedded. Below is the transition series with the usual appearance of Ochshawe Directly into Marlms the heavy bedded Coegmans contain any physical line of value in stratigraphy to separate from the Transition series. In the lower 2 feet of the Coegmans, the same fauna as that of the Trans- sition is present. In the next higher layer I at least 10 notes them at that. The first trace of normal Coegman fauna (one specimen of R. complicata) and six inches higher come the first Spicula selecta. This then is the faunal line to separate the Marlins from the Coegmans and must be regarded as the physical line as well. On physical grounds alone the Coegmans will begin with the first heavy bedded grey crinoidal limestone. In the 2 feet of debatable basal Coegmans occur single beds of Spm not apparently forst above here. Saw a single Ammatysora head about 8 feet above the physical base of the Coegmans.
