abundant remains in certain layers. The rock dips N. 25° W. 10°, and 

 shows cleavage planes dipping at a high angle to the southeast (1,477 A8 

 of C. S. P.). 



Farther up the Neversink valley, a short distance north of Rose Point, 

 along the west side of the railroad, are coarse blue arenaceous shales, with 

 sandstones one foot or more in thickness. The dip is 45° W. and the strike 

 N. 8(»° E. Fossils are common (1,478 Al of C. S. P.). 



Prosser's most northerly station of Hamilton rocks in the township is 

 northwest of Cuddebackville and one mile northeast of Rose Point, where 

 the black argillaceous and arenaceous shales crop out at the base of the 

 hill. The ledges farther up the hill contain abundant Hamilton fossils ( 1,47s 

 Bl of C. S. P.). 



Following the road westward from Huguenot over the hills to Hones- 

 ville, the following beds were observed. 



A short distance west of Huguenot (66) were black indurated shales and 

 sandstones of Hamilton age, in layers about one inch thick. They strike 

 N. 40° E. and dip 80° AY. 



About one mile farther (67), at 700 feet A. T., coarse sandstones, striking 

 N. 50° E. and dipping 80° W. were met. They are thinly bedded and con- 

 tain numerous plant stems, as well as fair specimens of Lepidodendron 

 gaspian urn. A mile and one half west of Huguenot, at a bend in the road (69), 

 and 710 feet A. T., with the strike and dip the same as before, are calcareous 

 sandstones with an abundance of fossils in certain layers. 



The remains are closely packed together. Those determinable were: 

 Spirifer muoronaPus (very common), Spirifer granulifer, Spirifer fimbriatus 

 (showing the dermal spines), Spirifer audaculus, Leptodesma Rogersi, ( 'honetes, 

 a small form of C. eoronata or syrtaMs, Ohonetes scitula, J\ r iicuJit<-.s triqueter 

 (small form), Spirifer mesastri<iUx, Leptodesma, sp., Microdot/, sp., Tropi- 

 doUptus, sp., PJmcops rcma, Goniophora, sp., Aihyris sp., Tropidoh ptit* 

 cwmatus, Leda dwersa, Nuculites oblongatu.s, Grant in ysia sp., Lingula, sp., 

 Leiorhynchus, sp., plant stems. The plant steins occur in the same layers 

 w ith the shells, and concretions are not uncommon. 1 regard this outcrop 

 as of Hamilton age. 



At the summit of the ridge (70), 1,265 feet A. T., the bluish grey sand- 

 stones appear and, a little farther on, interbedded red shales which strike 

 nearly north and south, and dip 20° W. These red shales crop out along the 

 load through the woods to the west at several points. This region is an 

 elevated flat-topped ridge covered with a thick grow th of scrub-oak.
