Oct. 2 Spent the day at Partridge Point which is said to be six miles south of Alpena but I do not believe it is more than four along the shore. On the north side of the point near where Mr. Me Calla's fisherman house the shaly Hamilton beds come to the surface. Their thickness here is not more than a foot or two all above being loose material worn well thrown up by the lake surf. At this place I secured a number of fine braggan slabs and ten specimens of Dolatocrinus. Brachiopods are rare, The only recognizable corals are Farretia placenta a Diphyphyllum and Cystiphyllum. See Oct. 9th. Also picked up three Cordaster and one Anulocrinous. At Stoney Point north of Part. Point the rocks are too small worn for me.
