A group portrait of 'The Engineer Force,' the division of firemen, machinists, coal passers, and engineering officers who kept a coal-fired warship's boilers and propulsion machinery running. Posed beneath the ship's boats and beside a deck gun, this image captures one of the essential -- if less glamorous -- departments of a turn-of-the-century U.S. Navy cruiser, circa 1898-1910s.
