Dowager Queen Alexandra--and the Princess received from Mr. Johnson as a souvenir a tiny electric chandelier fashioned like a bouquet of fern leaves and flowers, the buds being some of the first miniature incandescent lamps ever made. The first item in the first Bulletin dealt with the "Fire Question," and all through the successive issues runs a series of significant items on the same subject. Many of them are aimed at gas, and there are several grim summaries of death and fires due to gas-leaks or explosions. A tendency existed at the time to assume that electricity was altogether safe, while its opponents, predicating their attacks on arc-lighting casualties, insisted it was most dangerous. Edison's problem in educating the public was rather difficult, for while his low-pressure, direct-current system has always been absolutely without danger to life, there has also been the undeniable fact that escaping electricity might cause a fire just as a leaky water-pipe can flood a house. The important question had arisen, therefore, of satisfying the fire underwriters as to the safety of the system. He had foreseen that there would be an absolute necessity for special devices to prevent fires from occurring by reason of any excess of current flowing in any circuit; and several of his earliest detail lighting inventions deal with this subject. The insurance underwriters of New York and other parts of the country gave a great deal of time and study to the question through their most expert representatives, with the aid of Edison and his associates, other electric-light companies cooperating; and the knowledge thus gained was embodied in insurance rules to govern wiring for electric lights, formulated during the latter part of 1881, adopted by the New York Board of Fire Underwriters, January 12, 1882, and subsequently endorsed by other boards in the various insurance districts. Under temporary rulings, however, a vast amount of work had already been done, but it was obvious that as the industry grew there would be less and less possibility of supervision except through such regulations, insisting upon the use of the best devices and methods. Indeed, the direct superintendence soon became unnecessary, owing to the increasing knowledge and greater skill acquired by the installing staff; and this system of education was notably improved by a manual written by Mr. Edison himself. Copies of this brochure are as scarce to-day as Firs
