northern part of which consists of the Hamilton sandstone 

 of South furnace hill, and the southern of the limestone and 

 Oriskany sandstone brought up by the fault. It is evident, 

 therefore, that its throw is much less than further east where 

 the Chemung was brought against the same limestone. Es- 

 ti mating the thickness as before, the total displacement can- 

 not here exceed 1300 or 1400 feet thus distributed : 



Hamilton sandstone, 600 feet. 



Hamilton lower shale, 400 " 



Marcel 1 us shale and limestone, 200 " 



L. H. limeshale and limestone, 200 " 



1400 " 



Continuing to the southwestward the direction of the fault 

 is not quite parallel to the strike of the beds, being rather 

 more nearly east and west. Consequently it cuts continu- 

 ally deeper and deeper into the Hamilton sandstone, thus 

 thinning down its outcrop until at the distance of about two 

 miles the sandstone is altogether cut out. The South Fur- 

 nace hill composed of this outcrop of sandstone therefore 

 becomes lower and lower and ultimately disappears, and the 

 shales between it and the limestone come together. Fur- 

 ther than this I have been unable to follow it, there being 

 no hard rocks except the Oriskany sandstone, the line of 

 outcrop of which shows very little, perhaps no, displace- 

 ment. Moreover the Oriskany itself is largely eroded along 

 the line of the fault. 



The Little Germany fault. {PL XXXIX.) 



A fault develops itself near the hamlet of Little Germany, 

 in Spring township, and runs east-northeast into Centre for 

 nearly six miles. Though far inferior in length and throw 

 to the greal Perry county fault, it yet produces much com- 

 plication and several note-worthy changes in the topography 

 and Landscape. The mosl Important of these lie in Centre 

 township, 1 > 1 1 1 several musi be noticed here. The most 

 western point :it which I have been able to detect the fault 

 is on the hill west of Little Germany where it produces a 

 foik in the ( Oriskany sandstone, one ridge continuing on its
