152 About 2 miles Northeast of Seb- (105) an in the Brad fordville LS road, the head waters of a nor- them branch of Cany Creek cross the road. North east of the road is Mr. Drye's farm. On the hill side west of the fence are sever- al exposures. The Black slate is present. Below the slate are 9 ft 4 in. of Devonian rock. The upper part of the Devonian has a dark brown color. This color is due to weathering, and the breccia- ted appearance is due to the frag- ments of fossils present. Good fossils are weathered out Cincinnati group fossils, both loose and in thin limestone, are common about 7 to 8 feet below the Devonian. A blue clay layer with nodular mas- ses of limestone, is found 1 a 1/2 feet above the cithly fossiliferous part. The interval between this blue clay and the Devonian is occu- pied by brown clay shales only a small part of the Madison section remaining. Pre-Devonian erosion is the probable cause. 153 About 3 miles Southeast of (989) Sebastian where the branch just mentioned enters Cany Creek West of the road corners is the farm house of Geo. Raley. The black slate is seen between the house and the old mill. The Coniferous is 11 1/2 feet thick. The upper 2 1/2 feet consist of the dark brown brecciated layer. The part immediately beneath contains some chert than the middle and lower parts of the De- vonian section. Lower Silurian fossils, both loose and in thin limestones, are seen in situ, very abundant, 1 foot below the Devonian. They restably directly underly the Devonian 1 foot not ledgy ex- pured. Columnaferia celtica was occured 1 foot below the De- vonian. At second visit it was seen that 7 ft 8 in of limestone, full of fossils, lay over the thin bedded Madison sand under the Coniferous.
