working anywhere in Perry county. Most of the ore taken 

 from it was mined during the years following the war when 

 the price of iron was high. 



The Hamilton Upper shale, (VIII.) 



These shales may be found exposed in their usual posi- 

 tion—over the Hamilton sandstone- -wherever the ore has 

 been opened. At Girty's Notch the Paracyclas shales have 

 been largely excavated in mining the ore and abundance of 

 the characteristic fossils may be obtained in the spoil-bank. 

 This is the richest locality with which I have met in the 

 county for these fossils. 



The same fossils may be found at the other two outcrops 

 of the fossil ore but less abundantly, less shale having been 

 taken out. 



Near the last of the three outcrops alluded to when writ- 

 ing of the fossil ore the Tropedoleptus bed may be found 

 about 100 yards to the southward showing its typical color 

 and fossils. 



The Genes see- Portage-Chemung shale, VIII 



This group as shown on the map occupies a broad belt of 

 the township extending from the Juniata to the Susque 

 hanna. The breadth of this belt of ground, however, indi- 

 cates nothing in regard to the thickness of the rocks. It is 

 impossible to measure them here, in consequence of the 

 numerous folds and flexures they exhibit. The cliffs along 

 the road by the Juniata river show nothingbut a succession 

 of rocks dipping at varying angles from vertical to horizontal, 

 and a series of anticlinal arches sometimes only a few feet, 

 sometimes many yards across. It is consequently quite im- 

 possible to establish any subdivision in the great mass of 

 olive shales and sandstones without much more expendi- 

 ture of time than, the exigency of the survey allowed. 



It is, however, quite certain that the rocks of this group 

 thin down to the southeast. Careful measurement with 

 approximate allowance for repetition by folding would not, 

 I think, give them here more than one half the thickness 

 they have at Newport, only six miles away.
