stone render it conspicuous to the eye when used for build- 

 ing and walls composed of it in combination with the yellow 

 Oriskany, the Medina and Hamilton sandstones, the Ore 

 sandrock, the green Marcellus, and the blue Lower Helder- 

 berg limestones resemble a piece of patchwork on a large 

 scale. 



The outcrop of the stony Hamilton lower shale above de- 

 scribed closely accompanies that of the Hamilton sandstone 

 which is here much more shaly than at its southeastern ex- 

 posure. The two are consequently less easily distinguished 

 than usual. The broad area formed by the low undulations 

 mentioned above in the southwest of the township, is owned 

 for the most part by Captain Andrew Loy, and is known as 

 Captain Loy's tract. 



The Hamilton sandstone, (VIII.) 



Entering the township from Juniata the Hamilton sand- 

 stone makes a bold outcrop in the Buffalo hills. But the 

 bed gradually growing more shaly and its dip gently flat- 

 tening the boldness of the ridge as slowly disappears, and 

 in the west of the township it forms no conspicuous feat- 

 ure. 



The set of small folds described in the report on Madison 

 township and already alluded to in this report influences 

 the Hamilton sandstone, which, in consequence, exhibits a 

 series of very gentle undulations and exposes a great sur- 

 face. So much has been said of this part of the township, 

 under the head of the Lower Hamilton shales, that more is 

 unnecessary. 



The gap cut through this sandstone by the main stream 

 of the Buffalo creek and the romantic scenery thus pro- 

 duced have been alluded to in the general description at 

 the head of this chapter. The dip of the rocks at this place 

 is about 30°-4()°, and the ravine is excavated from the 

 longest of the small synclinal folds which have been already 

 mentioned several times. In this township the ridge is 

 known as Bilman ridge. Further east in Tuscarora town- 

 ship it bears the name of Raccoon ridge.
