Sept. 29, 1940
Pegram on Mill Creek, N of Topsy, Tennessee. TVA Topsy [[square symbol]]

Point out in paper if any of Pegram is really Onondaga there must have been big interval between Lower Onondaga (Camden) and Upper Onondaga [[underlined]] Sp. acuminatus [[/underlined]] zone to have produced the Camden and Clear Creek Cherts, which generally are chert wherever known.

The Pegram on Buffalo River in bluff on west side of mouth of Mill Creek, north of Topsy is about 6' thick of hard light to dark gray crystalline limestone, irregularly bedded in layers from one to two inches up to nearly a foot. Contains many styliolites. Basal layer in bottom few inches contains concretions and a green mineral probably glauconite. Fossils are scarce throughout. Saw nothing while collecting to indicate anything of Onondaga age. In basal bed occurs tavosites turbinatus suggestive of Beechwood with a large wrinkled Schuchertella. In middle of formation saw possible Vitulina (or dorsals of Cyrtina). Near top Cypricardinia is common. All fossils seen suggest a Hamilton age for whole layer rather than any Onondaga.

Sp. gregarius is only real Onondaga fossil in Pegram reported by Peoples. It could be a Delaware form. In paper show Nucleocrinus vernenili also of Hamilton type. [[underlined]] Pegram may all be Hamilton. [[/underlined]]
