A poster comes to life. "This is what I call warm hospitality," said Chief Radioman Evans in his dry Georgia manner as the three men stood in 140 degrees of heat looking into the door of an electric furnace. The furnace makes silica steel which is used to make transformer cores. Some of Evans' radio equipment, back at his base, uses transformers whose cores may well have come from this furnace. Allegheny Steel, Pittsburgh, Pennsylvania
