October 23, Thursday, Ardmore. At 7.30 it was still dark and very threatening. By 8.30 it seemed to be clearing and by ten in was a bright day. Started at 8.30 first south to a place one mile south of Ardmore to see a Frasulina li, beside the road and a quarries. The li is 20 feet thick and is 15,000 feet above the base of the Pennsylvanian (= Osmanella), or 3000 feet beneath the top of the same series. In places the li is earthy and where the Fraslinian occurs is a fine li. But few other species occur. See the small list. Crinoidal matter is common. He then went to the D.P.Y Lee 12, T.O.S. R.IE or one mile east and four miles south of Ardmore. Here about six wide thick occurs a living sandstone standing on edge, and of a white color. It is replete with specific gravel, crystalline and some other species. See the list collected. The whole sandstone zone is 6 feet thick. This zone is about 13,000 feet beneath the top or 10,000 beneath the Frasulian zone previously described. In another locality hereabouts the zone is a limestone, and in still another place it is a limestone conglomerate. This fossil is the best guide as far seen. Keyes calls it D. condr. or S. tornensis.
