Schofield mine. Ore was mined here between the years 1828 

 and 1845 and used in the forges at Schroon. The openings extend 

 for several hundred feet along Skiff mountain near the base, trend- 

 ing about northwest and southeast. Apparently the excavations 

 do not reach much over 100 feet in depth. The ore is rich, but 

 does not average above 3 feet in thickness. A large quantity of 

 waste rock has been taken out in working the deposit. The fol- 

 lowing analysis by J. B. Britton is reported by Maynard:
