Actual thickness about 44 inches Dip 40° ⑦ Thin-bedded, platy, light-greenish dolomitic limestone that across the strike measure 26 feet. Dip about 40°. Upon two-thirds has gone with Martinia glabra. About 4 feet of actual depth from this is the zone of Productus described by Beede. This Productus zone is about 2 feet thick with them crowded in layers. Productus beds are also well seen in Huff. ⑧ Soft thin bedded greenish rotten magnesian li- mestone in which there is some comminuted crinoidal material along with Productus, Martinia, Spirifuria Pupray and other forms. Actual thickness 32 inches. Seen in Huff; also all the layers below this one. ⑨ Still softer greenish material like the above but breathers out as a shale. Saw a fine large Leminula calcareous a Composita. Fossils must be looked for here very carefully, occurs as free forms. Actual thickness 25 inches. ⑩ One bed of similar material but stands out as a dolomitic hard layer. Ten inches thick. ⑪ Soft blue-greenish shales down to next harder dolomitic layers. Estimated thickness 7 feet, 6 inches. Strike N., 62° W. magnetic. Dip 53° N.N.E. ⑫ Thin bedded grayish dolomitic limestone tending to pass below into either lards. have actin and coming out into at
