The loss in iron and other metals, owing to the same cause, is utterly incalculable. The recent discoveries in magnetism point to the solution of the problem and the utilization of the waste. It is not impossible that the electro-magnet contains more gold for its fortunate inventors than all the mines of the earth will yield to operators during a single year.
