D. M. Steward Manufacturing Company, of Chattanooga, Tenn., have issued a very neat and effective illustrated catalogue and price-list of their specialties, including their well-known lava electric insulators, which have stood such remarkable tests in practical work, at the hands of various companies. The insulators are fire-proof and water-proof, do not warp and are extremely hard, resisting all mechanical injury.
