About 5 of a mile soiitlioast of Marcellus village is DiiiiR'a 

 hill, a knoll 10 or 50 ftn't lnj.-li. The A*,^ouiiitjle liiiK'stone 

 iipiH'ars hen* in a j^rade euttiiij;' on the west «itle of the hill 

 ami ajjain in a Ih'ld on tho »onth side, and over a 

 considerable area it is coveii'd h\ only a lliin hi.vcr of t^oW. Its 

 thickness is 2 feet fJ inches in two layers. In tli<' immediate 

 vicinity of this locality iwv otlicr ontcrops wliicli the searcher 

 foi- the inlcicsiin;^ fossils of the limestone wonhl «lo well to 

 exploit. It may be noted however, that frequently the rock is too 

 deeply seamed and etched by weathering:: to justify the labor, 

 often j?reat, of altemptinj,^ to collect from it. It is not only of 

 impure character, but the purer calcareous nmttci- is arranj^ed 

 in spots and patches in such a way as to afford least resistance 

 to decomposing agencies. This is notably the nature of the 

 rock in the exposures in J)unk's hill. Another small outcrop 

 occurs in the side of the road about a mile farther toward Cedar- 

 vale and again across the valley toward the southwest, where 

 the rock is very com])act and lies clos«^ to the surface over a 



large area. 



Slate hill is situated about 'i of a mile southeast of Mar- 

 cellus village, having the valley of Nine-mile creek on the 

 west. It is composed of black and dark blue shales and shows 

 on the north side along the road at its base a slight exposure 

 of the Agoniatite limestone, and the dark <alcareous shales 

 beneath are exposed for a thickness of about 3 feet, on the south 

 side of a neighboring depression. On the dugway road up the 

 hill, black fetid shales are exposed to a 'thickness of about 20 

 feet, and above them on the west sIoih' of the hill the ui)per 

 blue black shales are shown. We shall observe in more west- 

 ward sections that the hori/on of the Statlord limestone is 

 approximated at the junction of these bitumiiions beds with 

 the blue black shales above.
