May 21 - drove 1/4 mile north to Jeffors Williams mill locality. This is at a bridge crossing the Big Sandy creek about half C. The exposed horizon is on the bottom side, seemed quite all lignite peats. The exposure is about 30 feet and is are a blue shale. This the Belthyme shale as exposed in New York. The lowest layers hold main Atypus reticularis followed by Anastrophus beds and then the Orthus beds. It is in the center of the Orthus bed that this Anastrophus occurs. The Phlepsi's are found for the Anastrophus have exposures and also the Josephines. It is my belief that the Allen mills beds are below them.
