3. CENTRE TOWNSHIP F 8 . 195 



No other attempt lias been made so far as I am aware to 

 open and work the ore along this line of outcrop. 



Another small outcrop of the limestone ore occurs near 

 the Perry furnace in the southwest corner of the township. 

 It runs in a curve round the furnace between the Oriskany 

 sandstone and the black shales, but is of very small extent, 

 and so far as I am aware was never worked in the township 

 though a small opening exists a short distance over the line 

 in Spring township. 



Another outcrop of the Marcellns ore occurs about a mile 

 north of New Bloomfield, where in one of the long, narrow 

 synclinal folds running southwestwardly from the old Ju- 

 niata, works it has been mined in the woods under cover. 

 This outcrop may be traced on the ma]3 of the county north 

 of Bloomfield. The works are now abandoned and have 

 fallen in. The ore was hauled half a mile to the stream in 

 Dorran's narrows for washing. 



The outcrop at the old Juniata furnace is the last of which 

 mention need be made. This is at the same time the oldest 

 and most productive in the township and second to few in 

 the county in these respects. It was worked for the fur- 

 nace half a century ago and immense quantities of ore were 

 extracted at great cost, especially in the eastern portion of 

 the works where the cutting is about twenty-five feet deep 

 and open. Traces of the old works may be found scattered 

 through the woods on the west of the road nearly half a 

 mile distant. These works were abandoned about forty 

 years ago, when the introduction of coal and coke ruined 

 the charcoal-iron industry and they lay idle for many years. 

 They have, however, been reopened by driving a tunnel 

 through the Oriskany sandstone ledge on the north side of 

 the syncline. whereby access has been obtained to the ore 

 beds lying within it and a considerable quantity of ore ex 

 tracted and hauled to Xewport by Mr. Reeder. 



The position of Mr. Reeder s works and tunnel is shown 

 in Plate XVII, page 178, Fig. 1.
