Three and one fourth miles w. n. w. of West Fulton in school 

 district no. 7 the main branch of Panther creek turns sharply to 

 the north; but the section follows the highway toward Summit 

 and the smaller branch of the creek up the hill to the west. Some 

 490 feet higher than West Fulton, on the south side of the road 

 after crossing the west branch of Panther creek and passing the 

 road on which the schoolhouse is located, are quite thin, bluish, 

 argillaceous shales (C 2 ) certain layers of which contain abundant 

 specimens of the very mucronate form of Spirifer m u c r o - 

 n a t u s (Con.) Bill, associated with C h o n e t e s eoronatus 

 (Con.) Hall. These shales are clearly in the Hamilton forma- 

 tion. The following species were collected : 



1 Chonetes eoronatus (Con.) Hall a 



2 Spirifer inucronatus (Con.) Bill, a 



3 Cyrtina hamiltonensis Hall rr 



4 Cainarotoeehia congregata (Con.) H. d C. rr 



5 Maerodon hamiltoniae Hall (?) rr 



Imperfectly preserved. 



6 Orthonota undulata Con. rr 



7 Prothyris laneeolata Hall rr 



For 50 feet the hillside is covered, when another outcrop of 

 coarser and more arenaceous shales (O 8 ) are reached which also 

 contain abundant Hamilton fossils. The shales are capped by 

 very thin bedded, even sandstones and the zone is clearly in the 

 Hamilton.

2 S. audaculus (Con.) H. d C. c 



3 Camarotoeehia congregata (Con.) H. d C. c 



4 Pterinea flabellum (Con.) Hall rr 



5 Liopteria bigsbyi Hall (?) r 



Broken and poorly preserved. 



On the hillside 55 feet above C 3 , or approximately 595 feet 

 higher than West Fulton, are thin, bluish gray sandstones (C 4 ) 

 in which a few fossils occur. This ledge is about on a level with 

 the small cemetery on the north side of the road, and is appar- 

 ently in the Hamilton formation. 40 feet higher is a ledge of 

 thin bedded, bluish gray sandstone five feet in thickness. A little 

 below this stratum are loose fossils which seem to have come from 

 this outcrop and apparently show its Hamilton age. At the edge 

 of the woods on the south side of the road are ledges of rather 

 coarse grained, thin bedded, grayish sandstone (C 5 ). There are 

 from 15 to 20 feet of these sandstones exposed, which apparently 

 occur on the north side of the road at a little higher elevation. 

 No fossils were found except plant stems; but there are numerous 

 clay pebbles in some of the layers. This zone is probably near 

 the dividing line between the Hamilton and Sherburne forma- 

 tions and it is a matter of some uncertainty to which formation
