on the road to the Old Perry furnace near the residence of 

 Mr. G-eorge Meek. r rhis outcrop is produced by a small 

 fault which brings up the sandstone of the south side of 

 Crawley hill after il has sunk below the surface. Its ex- 

 tent is small and it will be found described with the other 

 faults. See section. 



The fifth outcrop of the Hamilton sandstone will be 

 found a few hundred yards south of that last mentioned. 

 This, which is also anticlinal, is less compressed than the 

 two preceding, and as it continues to the west-southwest it 

 gradually opens and discloses by erosion the Lower Hamil- 

 ton and Marcellus shales, and farther west the Oriskany 

 sandstone and Lewistown limestone. It thus forms two 

 nearly parallel monoclinal ridges meeting at an apex at the 

 eastern end. These are known in the district as the Fur- 

 nace hills, north and south, and afford beautiful views of 

 mountain and woodland scenery to the traveler driving or 

 walking along what is well named the Tape- worm road. On 

 a smaller scale the view resembles that in the Cove, but 

 there the geological structure is synclinal while here it is 

 anticlinal. The two however produce similar results on the 

 landscape. 



The Sixth outcrop of the Ham ill on sandstone and the 

 most southerly in Centre township is in the range of Dick's 

 hill. This, the highest and boldest ridge in the township, 

 is about four miles in length, reaching from a point one 

 mile and a half west of Loslrs Run station to the old road 

 from New Bloomfield to Carlisle. This, like Mahanoy 

 ridge and the Buffalo hills, is monoclinal. the northern half 

 of the anticline, of which it was once a part, being con- 

 cealed by the grea! Perry county faults, an account of 

 which will be found in another chapter. 



Dick's hill is a rough wooded ridge steeper on the north- 

 western than on the southeastern slopes, and rising near the 

 western end to an altitude of about :><><> feel above New 

 Bloomfield. Only one gap exists through it. the picturesque 

 Montebello narrows, through which passes the Little Juni- 

 ata. Alter flowing nearly parallel to the range along its 

 whole Length and gradually approaching it. this stream
