Three miles southeast of 503 A, by the highway between the villages 

 of New Berlin and Morris, are a series of outcrops, which have been 

 called 503 B. These ledges begin near the foot of the long hill, the 

 first a half mile or more beyond Fink's sawmill. The rock consists of 

 rather coarse, blue, argillaceous shales, w^eathering greenish, alternating 

 with thin, fine-grained sandstones, and all iron -stained after weathering. 

 Fossils are extremely rare, none being found in ihe exposures which 

 were hastily examined. 



A mile farther up the hill from 503 B, north of the highway and 

 just above a small creek, is an old quarry, not worked at present. This 

 exposure, 503 C, is considerably higher than 503 B. The quarry stone 

 is a blue, fine-grained sandstone, weathering to a brown, showing the 

 presence of considerable iron. Thin sandstones and argillaceous shales, 

 similar to those of 503 B, lie above the massive stone which forms the 

 lowest exposures in the quarry. The only fossils found in the quarry 

 were fragments of plant stems in a poor sandstone of the upper part. 

 In the soil just above the rock were large, flat angular stones containing 

 numerous fossils. These slabs had been probably carried but little 

 distance from their place of occurrence. The fossils are mostly Spiri- 

 fers and Rhynchonellas, but weathering and other causes have nearly 

 obliterated the finer charactej's. Chonetes and fragments of Lamelli- 

 branch shells were also noticed. 



503 D is a small exposure by the roadside at almost the summit of 

 the hill, and one-fourth of a mile from the quarr3\ These shales are
