86 Less than half a mile east- ward, just east of North Forke, 18 feet of the Lower Os good clay shale are ex- pired. The total section is not exposed. 87 Two fifth of a mile east- ward the Black shale rests in the Coniferous at (923 - I forgot to take a reference point.) The Coniferous is less than 2 feet thick. 88 Half a mile south of New Hope, the Lower Os good clay is seen to be at least 22 feet thick. The total thickness may be 25 feet. The Chintm is of the Bardstown type. Chest is found at all levels: small amount. A fairly heavy (3 in ch) chest bed about 5 feet below the Os- good shale contains fossils on its upper sur- face. The following is the list: Illaenus ambiguus, pen. Platy stroma Magareuse Arthis flabella Arthis elegantula Arthis biforata Plectambonites, elegantula Strephomena refulvida, Strephomena Hanoverensis. Streptorama calycula. Favrites fassus, medium Stromatopora concentrica. A single specimen of Plec- tambonites elegantula was found in the Lynest Clinton layer. The Chintm is a grey-blue silicene rock. Tetradinum occurs quite abundantly in the 3 feet of Lower Silurian rock im- mediately underlying the Chintm. The typical Madison rock is found immediately beneath. The trip of the Lower Si- lurian is at (856 - I for- got to take a reference point.)
