THE COVER: A fire in an abandoned factory on Chicago'_s South Side in February went to a fifth alarm with two specials. The fire was tho ght to be arson, since six separate fires were observed by the first-arriving, still-alarm companies. Intense heat drove fire fighters back over 500 feet and blistered windshields and paint on apparatus. Photo shows Chicago's Big John in action.
