In the planing mill is made everything from patrol wagons to the various sections of Swiss-chalet bungalows and skyscrapers. The painters supply the realistic touches, which are given finish by wall paper and designers' department. All kinds of mechanical devices are made in the machine shops, and in the garage the scores of autos used in the Keystone's activities are housed and maintained. Many touches of humor are added to the comedies by the sign painters' staff. The plumbing department provided water and sewerage connections.
