This is the iron age. It is displacing brick for building and wood for
ships. And yet how much goes to waste! Stoves, pots, kettles, rails,
machinery, wagon springs, car wheels, pillars, girders, and a multitude
of other forms of this valuable metal go to waste. The junk shop is a
mine. Manufacturers will pay you fifty cents per 100 pounds. The fact is
not generally known, but many junk dealers have become rich.
