Shipbuilding. "Liberty" ships. This maze of rolling cranes, at a large Eastern shipyard is a typical scene in many large shipyards at work on ships for Uncle Sam's Navy and merchant fleet. Stocks of material are piled up for the cranes to take to vessels under construction so there is no delay in production while waiting for sections or materials. All parts are prefabricated in this Eastern plant which formerly turned out freight cars. The completed sections are then carried six miles to the ways on flat cars.
