Grand Brere Aug 18 Friday
D2068 Mr Daniel Gare showed me a bed of fossils in the woods of his farm and it formed like the typical Ordovician horizon, the same one Clarke and I found five years ago at a lower level in the topography beside the small brook. Cracked rock are showing and reveal a good lot of material. The commonest species is Rhynchonella harandi. Other common forms are Spirifer crurichioni, Pholidomella musculosa, Hoffeningya procerinus (rare), Rineselaria (a large lenticular form), Ariculopsetta (many of these are one form by a thick hygrogram), etc.
In other closely adjoining layers found new Spirifer armatus, Meristella, Codolpina con- cara
This layer is not far above the hard clay near the top. I guess and I estimate this goes like several hundred feet below the beds on Davis Beach in them angles the true Ordovician horizon is several hundred & below the top of the (at least not less than 400 to 600 feet)
