Shipbuilding. "Liberty" ships. This is a travograph-oxy-acetylene machine, a cutter which treads its own pattern. Here it is cutting two identical floor plates for a tank section at the bottom of a new member of the "Liberty Fleet." The work is done at what was formerly a freight car plant now a large Eastern plant. All parts are prefabricated in this huge Eastern plant which formerly turned out freight cars. The completed sections are then carried six miles to the ways on flatcars. Bethlehem-Fairfield Shipyards Inc., Baltimore, Maryland
