| This is why the world has not heard so much of Mr. Tesla during the past year. Those of his friends who have been permitted to witness his late ex- periments at the new laboratory on East Houston street say that he has made some remarkable discoveries which will soon be announced
 had pleasant chat with Mr. Tesla the other day, and learned from him that he has about perfected his new Phosphorescent light, which will come as near artificial daylight as anything yet attempted. There will be no fla ment in the glass bulb; nevertheless, it will glow with all the brilliancy of an are light. The current employed will be of low voltage, but it will be changed into one of high potential by induction coils. In this way three Improvements will be effected over the present in- candescent lamps-brighter illumina- tion, no deadly wires and cheaper cost.
 Mir. Tesla is not yet ready to give to the public the details of his wonderful invention, but those who have seen the rev light say that will work a revolu- tion in methods of illumination. Some remarkable photographs have already been obtained from it. It is stated that the cost will be scarcely one-half of the rates that at present prevail.
 The third electrician who is grap- ping with the problem of cheap illu- Iuinatien is Dr. D. McFarlan Moore, who claims to have solved the secret of the firetly. Following close upon the heels of Roentgen rays, the discovery promises to work revolution in cleo. trie illumination, and foreshadows an era of one unbroken day.
 Mr. Moore is comparatively up- known to fame. For several years past he has been quietly at work in his Newark laboratory-whieh, curiously | enough, is within R stones throw of Edison's old place-and success seems at last to have crowned his efforts He calls the new kind of illumination 'ether lighting for want of better name, and employs only the most sim pie apparatus to manufacture it. IR- deed, like Roentgen.s rays, the wonder | is that some electrician has not before this time hit upon Mir. Moore's discov- cry. It is certainly as simple as it is remarkable in the effect produced. Not only is it the nearest approach to the production of light without heat that the world has yet seen, but the whole illumination is obtained from an ordinary current of low voltage.
 There are no hairpin filaments in Mir. Moore's system. as with the incan- descent lamp, and the illumination agent is distributed through pipes and tubes, just as we now distribute water and gas.
 MT, Moore's invention involves a new principle in molecular vibration. He separates the several divisions of energy, and employs only the illumi- mating clements. He hopes to get as much light with d one-volt current as Tesla now does with d million volts. In short, the new light promises to turn things topsy-turvey. We are cer- tainly on the eve of a revolution in elec- tric lighting, if Tesla, Edison and Moore are to be believed.
 Mir. Moore's new light, owing to the absence of heat, requires little power to generate it, and can be produced from a battery the size of that which rings tine front doorbeH. In other words an ordinary glass jar, contain ing pieces of zinc and carbon immersed in acid, will furnish current sufficient to produce a good illumination.
 Mr. Moore's apparatus is not much bigger than an ordinary-sized teacup, he, Ice !. circuit and corresponds to the electric bell is not bigger than ones finger.
 1 had occasion to visit Mir. Moore's laboratory the other day. Some of the experiments I witnessed were beauti- ful, and the light was certainly as good as one could wish. One experiment. struck me particularly After we en- tered the dark room the inventor hand ed me a long glass tube, about as big as a broom stick, and then ordered the lights out. In a few seconds, streams of light began playing through the tube from one end to the other.
 Of course I asked Mir. Moore to ex- plain.
 Tt is only a manifestation of elec- tricai induction,' he replied. smiling. "The current from the diminutive vi- orator is connected with small piece if tin on the ceiling, and the electric waves pass through the intervening air space to your body"
 If what A1r. Moore says is true, the possibilities of this enc feature of the new light are simply enormous. If, instead of piece of tin, metallic paint were put on the walls or ceiling and made part of the circuit, the same ef- fleets would be produced. The tube be- comes a yeritable stick of daylight. No wires or connections are needed. All that IS necessary is a glass tube in which the light can manifest itself. No matches, no oil, no gas, no buttons to press-all you need is a glass much like a walking stick. This new light prom ises to be bonanza to club man. h icrl4
