White fine grained fss. limest. 4-6 in. layer with nodules 6-10 in. 10 3/4 ft. Black slate 2-3 inches hard dark phosphate 4 ft. about. Waldron shale 33 1/2 ft Samuel limestone, trip orbito- base with 14 1/2 ft. Asgrod clay rock + clay shale D. 6 1/2-7 ft. Clinton light pink siliceous 8ft. Massive Madisim contorted B. 8 ft. banded Madison. A. 40 ft. Madison beds, banded clay rock in 4 ft. layers and limestone one (thicker) interbedded, guessed at. 20 ft. guessed at, Thin bedded Mad. shales, Q. occidentalis in layer near middle Richmond beds, Certhis ltp. Stmph. alternata, Rh. dentata. C. Later than as on next page. Cherty, Cherty 3 1/2-4 ft. Are the 3 ft of siliceous rock, underneath, See section west of Safayette. CmT the 40 ft. Madison beds belonging to the Madison series they show that the Madison beds change feathery into limestones SW. A. This is not disproved by the 8 ft. banded Madison which evidently, is only the upper part of the series below. Near the middle it contains limestone, but the fossils can not be readily recognized, being brand mix fragments, yet well preserved. The underlying this layer is the top of the 40 foot series, containing: Strophomena thin alternata, crummi in abrupt. Septuena zonicea, Cyclammina, canellibranchus, including byri- grains. The ride of the 8 ft. layer 8 ft., A., is fluid even when fresh and more clayey than calcareous in appearance? Samuelbranch in clay. B. The great 8 ft layer has a very even base and top not withstanding the fact that the layer itself is ap- parently very much contorted. It is still a thinish rock of clayey character like the rocks below. C. The Clinton is bedded, very much like some of the Madison beds but its color is more whitish or light pink, and it has the appearance of the siliceous limestones of Indio- ana. Near the middle+ This very fossil forms + cherty.
