From a discarded passenger automobile of one of its municipal departments, the city of Troy, N. Y., has created a well-equipped emergency car for use in air raids. Painted white, it has red blinker lights like those of ambulances and police cars. In the rear seat and trunk and on the roof are packed acetylene torches, steel helmets, water pumps, gas masks, lanterns, ropes, chains, fire extinguishers, ladders, pike poles, battering rams and various other paraphernalia.
