Saturday June 4, 1910. And Cumberland. Spend most of the morning at th D.B.B section. Looked into North for seeing sections. Just before noon visited th Compassville quarry. The lower part of the quarry n in the First Stromatopora bed and a little below it, the middle of the quarry takes in the ridge of the D.B.B. B. At the top in a thin irregular zone from 0 to 2 inches of decomposed residual clay and limestone pellets. Then there is the base of the New Yorkland, the beds below being the Creymans as at th D.B.B. Above the residual clay about 11 feet of the B. calarta beds followed by the Macrophleura beds. Just below the latter there in a thin zone I recent residual clay the place borders and hardly got them free New Yorkland foots. One sees here 15 feet of macrophleura beds making limestone. The D.B.B ridge, 6 feet thick is here 8' 6" thick. Upward above the macrophleura beds the hill steeply descends or then comes the shale is here permitting this easier access. The macrophleura beds can not be more than 1 foot thick when the shale must come in. The First Stromatopora bed is here 43 feet below the residual clay zone. Mr. A has a more detailed section. Thanks then one time back at th residual clay and again just beneath it.
