Freaks of a Cannon Ball. – A ball fired from a cannon which was being tried on Saturday at the Tredegar Iron Works, made a circuit in the air and came down through the roof of the city pump-house a long distance off. Passing through two floors and a floor beam, it narrowly grazed one of the large water-wheels, and then spent its force against the rocks forming the foundation of the building. The ball passed through a room in which the officers of the pump-house very often assemble, but luckily it was unoccupied at the time.
