E. and strike N". 32°. Toward tlic top the shales are more bluish and, in 

 slightly irregular layers of bluish to greenish shales are some fossils as 

 BucMola retrostriata v. Buch, Pterochaenia fragilis (Hall), and a small 

 Orthoceras. In the upper part of the cut there is a sandstone stratum over 

 2 feet in thickness with thinner sandstones above, followed by olive shales. 

 The sandstone weathers to a dark brown color on the edges of the outcrop 

 and the shales, frequently, to a yellowish-brown. These rocks are very 

 similar in lithological characters to many exposures of the Portage stage 

 in central, or the Sherburne sandstone in eastern New York. They are 

 referred to the lower part of the Woodmont which forms the lower member 

 of the Jennings formation in ^Maryland. About 4% miles north of this 

 locality in Southampton Township, Bedford County, Pa., Professor 

 Stevenson described " laminated brown to olive shales " on the road from 

 McLewees' Gap across Polish Mountain which he stated " may be regarded 

 as Portage." ' 



From the Woodmont as exposed from Town Creek along the jSTational 

 Eoad to the second turn on the lower part of Polish Mountain Dr. J. M. 

 Clarke has identified the following species: Bachiola conversa Clarke, 

 Buchiola liconiae Clarke, Buchiola retrostriata v. Buch, Pterochaenia 

 fragilis (Hall), StylioUna fissurella (Hall), Bactrites aciculus (Hall), 

 Orthoceras filosum Clarke, Proheloceras lutheri ( ?) Clarke. 



No. 5. On the National Eoad at the second turn east of Town. Creek 

 near the lower part of the western slope of Polish Mountain are fine, 

 olive, argillaceous shales with an occasional thin sandstone stratum. 

 These shales are moderately fossiliferous, containing Chonetes lepidi- 

 formis Clarke, Camarotocchia eximia Hall, Leptodesma, and some other 

 species, and breaking into very thin pieces soon cnjsh into powder on the 

 road, although they are used for road material. Up the mountain beyond 

 this point are shales and thin sandstones in Avhich fossils occur infre- 

 quently, but about 100 yards ahove the turn specimens of a small Spirifer 

 and large Camarotocchia were found. 



By the roadside above the second turn is a similar exposure of olive 

 shales with an occasional thin sandstone. Some of these shales are
