Donkey Boiler Demonstration on Hyde Street Pier, circa 1979
Images of park staff with the circa 1920s donkey boiler engine preparing for demonstration at Hyde Street Pier. These portable, steam-powered winches
were common along the San Francisco waterfront from the 1880s into the 1920s; they were used to lift heavy objects from the pier to the deck of the ship.
