Child Mine Workers

In this 1910 photo by child labor reformer Lewis Hine, a young boy carries an armful of steel rods known as "spragging irons" along the elevated track at the Bessie Mine of the Sloss-Sheffield Steel and Iron Company, Jefferson County. The iron bars were used to "sprag," or brace, the rear axles of wagons to prevent them from rolling backwards.
