172-Nearly two miles south- east of Perrice the road crosses the railroad just beyond a curve North of the track, at the Curve the Black Shale rests in the Cornifer- ous at 1210. The Cornif- erous is 11½ feet thick. 173-Half a mile eastward, just before reaching the Riley-Bradfordville road, the Black Shale rests in the Corniferous at 1055. The Cornif- erous rests directly on the Madison, but the Mad- isom is not thick so that a slant cut it once below the very fossiliform lime- stones come in. On Mad. son shows a strong dip southward. 174-a little over a mile southward on the Riley-Brad. fordville road this Black Shale rests directly on the Lower Silurian for a long stretch at 1[illegible] The exposures are good, li- ing along along the left side west of the creek. The Black Shale rests in 15 feet of Madison rock, at the base of which are 3 feet with Columnariaphora alve- lata, Tetradinum + plenty of Lower Silurian fossils. Below this is another great thickness of Madison beds. The Madison beds dips 175-Two miles south of the Railroad, the Lower Silurian rocks in the branch dip gently south- ward. 176-A mile and a half Eastward up the Northen Branch of Rolling Fork, north of the residence of Robert Hendley, the Black Shale rests in the Corniferous at 1086. The Corniferous is dark brown and is 3 feet thick. It lies directly on Lower Silurian in the Column- ariaphora alveolata and Cellus- ta.
