At the time that iron was mined in this region, the emery was 

 not recognized, and it is stated that it caused much trouble in 

 the blast furnaces on account of its infusibility. It was evi- 

 dently mistaken for iron, and charged into the furnaces. 



The emery outcrops on the hillsides, hence the mines are shallow 

 openings or quarries.
