The D. M. Steward Manuafacturing Company, of Chattanooga, Tenn., reported that their trade in patent lava insulation during the last four months of 1889 was a long way in advance of that of any other similar period. They received a number of single orders for 100,000 pieces, and hundreds for from 1,000 to 25,000 pieces. Among their regular and largest customers are such concerns as the Thomson-Houston Company, Bergmann & Co., the Western Electric Company, the Sperry Electric Company, the Detroit Eleectric Company, etc. "We never lose a customer," the company say. "Our insulation stands a greater heat than anything used for insulating purposes, and we make pieces to fit to one-thoudandth of an inch. No other insulator that stands heat can be worked so close to size. We have recently bought a newly discovered mine of the very best grade of crude material we ahve ever seen for insulators, and have tested it by working up about ten car-loads. We are more than pleased with it. As a test we have heated an insulator to a white heat, and plunged it into cold water without cracking or injuring it in the least."
