Spearman
Furnaces, owned and
operated by the Spearman Iron Company, were built in 1872. There are two
stacks, each sixty-three feet high and having fourteen foot bosh. No. 1
was blown in January 15, 1873, and No. 2, September 20, 1875. They were
remodeled in 1882 and 1885, respectively. Three Whitwell hot-blast
stoves are in use. The fuel consists of coke, and the product is foundry
pig iron, made from Lake Superior ore. J. J.
Spearman, of Sharon, organized the company, and superintended the
erection of the furnaces, and has ever since been the general manager.
