Wednesday. A. 19 ½ feet above river to a layer with small specimens of Sabellaria + Tetradinae. B. 15 ½ feet of limestone layers and clay layers in about equal pro- portion well interbedded. The layers about 3-4 inches thick. Here I found Stephanomena alternata, Crustellaria festivalis, Pterinea demissa. Orthis bifurcata, a form with scars by any large line. The uppermost layers contain good Sabellaria + Tetradinae. C. 11 ½ feet of massive limestone well exposed. D. These massive clayey beds with a few fossils, resemble the Madison beds in many ways but differ in containing fossils. At the very top is a bed with very many Orthis bifurcata. E. 11 feet of some kind of massive beds. Orthis occidentalis found within 6 inches of Black Shale. The base of the Black shale rested upon this massive bed and Prof. Miller dug out shale resting upon Orthis bifurcata, n and a manner that an impression of this fossil was preserved in the lower face of the Black Shale. Wednesday. F. 14 ft from limestone, with not many small crinoid heads + a few spirifers. Declined to break up into shaly fragments. G. 22 feet of massive white limestone, with gerdes, specially near the top = St. Louis according to Prof. Miller. At Rosena, The lower Richmond beds, 20 feet exposed on Sairo- pill side, about a horizon 1 feet just below Madison! &? 12.
