St Maurice Forges
Were situated on the river St. Maurice, about nine
miles above Three Rivers, Quebec. Iron ore was discovered on the banks
of the St. Maurice in 1667, but the mines were not systematically worked
until 1733, when a company was formed and forges established. Since that
date and until 1883, under different ownership, they were in active
operation, being the oldest blast-furnace, on the continent of America.
