6.  Jefferson Furnace, 1838, eight feet bosh, thirty feet high; on Beaver Creek at Jefferson Station; built by Arnold Plumer and S. F. Plumer, the latter became sole proprietor; managed by John Haslett.  It was run very irregularly; produced in 1845, 800 tons; in 1856, about 600 tons of forge metal out of limestone and bog ores; abandoned in 1858, chiefly on account of lack of timber.
