5) Clintn with Halysites ctenulatus many Stepheloceras large & small, Lyellia antinlmutus. At top are several thin layers (= 1 foot?) with Whitfieldella? + Penn. Stocklandisina? Meanur thickness of oosgro clay is 38 ft but owing to slope of the rock it is probably at least 45 ft thick. B one of Devonian seen. Fish- tooth layer = about 8 inches, Wint Tooth & lower bed, Weathering not 8 inches. Marine bed (1/2 foot) 38 22 1/2 ft. drive Clinton thin s 15 1/2 ft. limestone layers. Not collected? 6 S. of J.T. Elphins along Rm. From Clinton base to top of marine continuous exposures 10 ft 6 in. 5 1/2 ft chiefly clay & some limestone, 2 inches larger limestone. 8 ft clay, soft. 4-6 in solid brown limestone 5-ft stuffy clay 2-4 inches brown limestone, 12 ft blue clay 1 ft solid brown limestone. The distinction of this layer unknown. 1 3/4 ft unknown. 3 3/4 ft. Cherty Criniforms. 3 ft Black shale base is a clay rock. Tirezille black shale above. Further south at lowest point of around the line of Clinton is clearly seen resting of clay shale, Clinton to layer with large oozoid beads = 14 1/2 feet. The layer in which the beads occur disintegrates readily as do also other layers above the middle. The lower 6 1/2 to 8 1/2 feet are more solid. The layer taken as base of Osgood is more solid, unsbedded 6 in. More limestone up to 2 feet. 6 ft blue shale mixed with small limestone and rubble. 6 inch limestone, about 33ft to top.
