1 On the southern side of the run I had a good chance to break the limestone, It had un- mistakable Rochester fossils in the upper 3 rods, while at the very base I got large Athyra reticularis and Cheirotina citida. Therefore this limestone compares with the Rochester shale but may represent the so-called Clinton limestone in the Niagara fossile. Will see later about it. It is undoubtedly of the Clinton li. of the Niagara Base.
