100 F\ REPORT OF PROGRE89. E. W. OLAYPOLE. 



Buffalo Mountain syncline ; and near Manorsville it has 

 been mined under cover for some distance, but the roof of 

 the opening has fallen in. 



From this point east it may betraced by openings on 

 ii in several places — near the old Juniata furnace on 

 Inoculate run; again south of Newport; and at Gerty's 

 Notch on the Susquehanna river, where it was mined by 

 the Messrs. McCormick. 



Returning along the south side of Half Falls mountain 

 to the Juniata, where several hundred tons were once taken 

 out, it follows the south side of Mahanoy ridge and has been 

 dug on the farms of Messrs. Cook and Petermann. It makes 

 a small show near New Bloomfield ; but west of that town 

 it seems to be absent ; nor do we find it again until it reap- 

 pears on the south side of Crawley hill near the school-house 

 north of the Perry furnace. Here it is fair in quality and 

 quantity and has been mined to some extent. 



Prom here to where it is cut off by the fault it does not 

 appear, but on the other side of the fault in Wheatfield town- 

 ship on the south side of Dick's hill it is found again, better 

 in quality and quantity, on the farms of Messrs. Dachter- 

 man, Lickel, and Rathvon. It was mined here some years 

 ago by the Duncannon Iron Company. Here the bed is 

 double, or even triple, part of the Hamilton upper shale 

 becoming ferruginous. See report on Wheatfield township. 



Thence south westward along the south side of Pisgah 

 hill it makes but slight show, but reappears in full force 

 along the north slope of Little mountain, as tne Hamilton 

 sandstone returns along the other side of the Oak Grove 

 • Stony creek) syncline toward the Susquehanna river. 



Bere it 1ms been opened at several places, chiefly by the 

 Messrs. Seidel, of Marysville, and appears to be thicker and 

 1 letter than anywhere else in the county. 



I have observed no signs of any changes below drainage 

 level such as were mentioned in the reviews of the other 

 iron ores of Perry county, and it is probable that this ore 

 continues unchanged to greater depths. But the large 

 amount of lime it exhibits near Marysville suggests the pos- 

 sibility of its passing like the others into a ferriferous
