21. Col. Woodward' $ farm — now occupied by another family. 

 Going from Tippecanoe two miles east on the New Carlisle road, and 

 then south about a quarter of a mile, the house on the west side of the 

 road, is reached. South of the house is a shallow ditch exposing the 

 Clinton with Heliolites subtubulatus Halysites catenulatus, FenesteUa 

 [ifemiirypa ?) , Rhinopora verrucosa, Pachydictya instabilis, Orfhis clcgan- 

 tu/a, RhychoneUa scobina, and Platyceras (Platystoma) niagarense. 



The total section of the Clinton at this point was almost 23 feet. 

 This being about the highest exposure on the hill, the original Clinton • 

 at this point may have been somewhat thicker. See the Charleston 

 Falls section. At the base of the Clinton there is a white, fine- 

 grained layer, more sandy in texture, and about 7 inches thick, here 

 included with the Clinton. 



Beneath is a hard greenish layer, 3 inches thick, then 8 inches of 

 a soft, clayey, greenish shale. Then about 8 or 9 feet where there 

 is no exposure. Next, 23 inches of a very fine grained light brown 

 limestone including some thin blue more argillaceous layers, breaking 

 up into shaly fragments. Below this were about 6 feet without 

 exposure, underlaid by a series of thin bluish or brownish shales. 



22. Troy High Banks — three miles south of Troy, and two 

 miles north of Tippecanoe, along the western side of the Dayton and 

 Michigan railroad track. At the top of the banks the Clinton is 

 exposed. Its color exteriorly is brownish, owing to long continued 

 weathering but interiorly it is seen to be a whitish, coarsely grained 

 limestone, practically unfossiliferous. Beneath it are six and two- 

 thirds feet of a light brown rock, more massive than the shales 

 beneath, in layers two and a half and three inches thick, frequently 

 crossed by cracks, and unfossiliferous. It is more unlike the Belfast 

 bed as seen farther eastward and southeastward than the exposures at 

 Goe's Station and Donnelsville, but it has the same thickness and 

 occupies the- same position. Beneath the more massive rock are 

 twelve feet of blue thin shales, with annelid teeth towards the top. 

 Below are one and a third feet of a very fine grained limestone, 

 underlaid by the same thickness of blue shale, beneath which is a 

 foot in thickness of limestone layers, of Cincinnati age, as shown by 

 the presence of Orthis occidentalis and other fossils. Beneath this a e
