if a man is thus saved the expense of seeking what he will 

 never find lie is so far a gainer. 



The first and most striking feature of the map is the ex- 

 tension of long tongues of the Oriskany sandstone through 

 the Lewistown limestone. Between the northern and 

 southern lines three such tongues may be counted. The 

 first comes down from the northeast, at the road-junction 

 near the Old Juniata furnace and runs for about two miles. 

 In this trough or syncline the Marcellus ore bed must lie, 

 but in this part of its course no ore is worked, nor can I 

 learn that any has been discovered. The ground is low for 

 the most part at the northeastern end, and the ore may be 

 deeply buried beneath superficial wash. About a mile to 

 the southwest, however, a considerable quantity was mined 

 under cover some years ago and washed in the stream about 

 half a mile away. Farther west than this no ore probably 

 exists. The syncline becomes narrow and close, and after 

 running as a single ridge for nearly a mile, is finally cut 

 out by erosion near Poplar Hill cemetery. 



Immediately south of the last and running southwest is 

 another syncline also narrow bu t yielding ore in much grea ter 

 profusion. Immense quantities were taken out to supply 

 the Juniata furnace when in blast. The holes still remain 

 on both sides of the road. Narrowing rapidly this trough 

 of sandstone thins out and ends in a point about a mile 

 from the road. But in this Y-shaped place are situated 

 Keeder's ore works, from which more is extracted than 

 from any other in Perry county at the present time. The 

 tunnel by which access is gained is situated on the north 

 side of the ridge of Oriskany sandstone, through which it 

 has been driven to reach the syncline containing the ore. 

 In this way good drainage is secured for the workings, and 

 the removal of the ore rendered easy. Further details may 

 be found in Chapter V, on the iron ores and in the account 

 of the Marcellus ore bed in Centre township. 



This syncline is cut out by erosion at a short distance 

 further southwest, then faintly reappears, but shows itself 

 much more distinctly on the road from New Bloomfield to 

 M a rkelsvi lie, where it forms an open synclineand contains the
