Tim omaha Sunday bee: November 11, no?. 4 ; In the Field of Electricity A Serine hy Eleetrtelty. INMOST simultaneously from two different places in tha United States the Invention of a device for seeing at a distance by elec trical means is announced by twj uirrerent Inventors. The name adopted by each Inventor for his device la "Tele vue." The naniea of the two Inventors are given In Cssslcr's Magazine ae J. B. Fowler and William II. Thompson. A description of Mr. Fowler's device In one of the electrical papers shows a woman speaking Into a telephone transmitter, while at the side of the transmitter Is a projection akin to that of a hand stereo scope. The Idea la that tfie apparition of the person at the distant end of the wire will be seen vithln this prci-"p It la said that four wires are at present required to accomplish the speaking; and seeing, but that eventually two wires only will be necessary. It is also said ' that natural colors are reproduced In the ap paratus. Complete details of the operation of this Interesting apparatus are. withheld. It Is aid, for reasons connected with patent office matters. In the meantime, however, it la reported that a company has been or ganized to push the scheme and stock In the company will be offered to the public. Mr. Thompson does not appear to have progressed so far with hla Invention as Mr. Fowler, but It Is stated on Mr. Thomp son's behalf that his device will be an im provement on the other one. In the absence of details It is obvious that no opinion can be expressed as to the valu of the claims of these gentlemen. It Is well established that the problem whloh they have set out to solve Is not an easy one Attempts have been made to solve it by men well equipped for the purpose, but thus fsr without success. Not long ngo M. A. Nlsco of Belgium made a careful study of many of the methods that have been proposed for see ing at a distance electrically, and con-, rluded that noro of the devices thus far experimented with possesses the necessary requirements for successful operation. . In the majority of the methods for. transmitting bight to a distance that property of selonlum by which Its electrical resistance varies with the Intensity of the light thrown upon it has been employed, but this use of the substance has not hitherto met the expectations of inventors. Wireless for Railroad Sis-nail insr. The Idea of applying wireless telegraphy to railway use Is not new, if one include under this Item the early 'attempts of Phelps, Sniltlv Brown and others with the so-called induction system. So far n actual use Is being made of the few system of communication for controlling railway trains, but Dr. E. Nesber describes in a Berlin technical journal some interesting experiments made qn this field, near Berlin. A station was equipped with aparatus of the Telcfunken system, and a horizontal aerial was adopted, 'about 210 feet long, 190 feet of which was stretched between two telegraph, poles , twejve Inches below ; the telegraph wires, the remainder of the length being made up of the connections to the sending apparatus. A car attached to a steam-hauled train was fitted up with pendent says. It would turn a parlor into a morgue or a seance room. But recently It is reported that German chemists have overcome this dlfflcultp by putting Into the electrons other metals be sides mercury, thus changing the character of the light and making It approach the light of common day. Zino with 10 per cent of bismuth and a trace of sodium Is used for this purpose. If this proves prsctlral we, shall have our houses cheaply lighted "by softly glowing tubes arranged In all sorts of artistic de signs oh the walls and ceilings Instead of one or more points of light too bright to look at directly. Prodartlna of Alasnlaam. At the meeting In New Tork of the Elec trochemical society Dr. Charles F. Chand ler, Mitchell, professor of chemistry, gave a review of the work performed by C. M. Hall In connection with the discovery of an electrical process for the production of aluminum. A striking feature of Oils process. Prof. Chandler said, was the de vice thought out by Mr. Hall for the pro tection of the workmen from th scorch ing Irradlance of the melted cryolite, which enters as one of the most Important factors in the process. He has found that Dulverlzed charcoal refused to mix with the seething mass of metal, although as a rule ' powders have the tendency to become In extricably fused with metals under such oondltlons. The charcoal. Prof. Chandler j said, "sheds the cryolite as the duck sheds water, and no matter 'how well the mass 1 Is stirred the powder comes to the surface j again, to form a distinct and easily ab ' stracted top layer." Huch a layer Is now Introduced by Mr. Hall for the double purpose of screening the workmen from ) the rays of the melted metal and to carry a stratum of powdered aluminum ready for mixture with the cryolite when, needed. And by another very Ingenious device a small Incandescent light, suspended over the jar. Is made to signalise the absorp tion of the aluminum already put In and the reed for more. Is -4- Electrlclty ta the . Hotheur An astonishing invention by Mr. B. H. Thwalte, a British engineer, for the Culti vation of plants by electricity has certain features which are both new and original. In the patent specification Mr. Thwalte says: ','My Invention consists In harnessing the Intentional and consequential products of a combined suction of pressure-producer gas engine and elsctrto energy generating plant for providing all the denned and ben eficial Influences on plant life in, an eoo nomlo and effective 'manner. I utilize the Jacket water of. the gas engln for heating the conservatory or glass house. I also utilize the carbon dl-oxlde of the gas en gine exhaust gases for feeding the leaves, first purifying such gases before allowing them to enter Into the immediate environ ment of the plants." Mr. Thwaite's re sume of his discovery is certainly both in teresting and suggestive. He says: "It is remarkable that the most sconomlo method of Converting the heat of coal fuel rnto work is also the moat perfectly applicable to the electrical, thermal and chemical ' stlrrrulatlon of organlo vegetable Ufa.

The operation of the system wss found In no way to interfere with that of ,the ordi nary telegraph lines running along the road. Evolatloa of the Electric Light. Fireflies are still In advance of mankind In the matter of economical light-producing. The phoHphorescwnt glow which they give off Is nearly pure Itpht. Vry little of the energy Is wnsted In heat, whilo in the case of the lighting devised by n-.an more power Is used up in producing heat, which is usually not wanted, than is con- verted into visible light. " The nearest we have yet come to follcw. ing the fireflies is the mercury vapor light developed by American Inventors, which. in the form of long, glowing tubes, has coal.

"Third The carbon dl-oxlde of the per fect products of combustion of the power gas. i "Fourth Their sensible heat, all being available and efficiently utilized In addition to the electricity transformed power, to effect the object in view." ' ' ' New Element Discovered. It is reported that 3. R. Rydberg, pro fessor in physics at the university In Lund, Sweden,' has a new theory about chemical element. In working on the same he came to tha conclusion that there must be an element having less atomic weight than any element heretofore known; in fact, only a small fraction of the atomic weight of hydrogen. It Is further stated that such an clement, the electron, was known be fore, but that Professor Rydberg has dis covered that it does not consist of any separate kind of material. It Is thought been seen In our shop windows as advertise- that lhe consequence of this will be very ments for two years or more. Thry produce more light at less cost than any otlwr practical method of Illumi nation and would bo extensively used if it were not for the color of th light. It contains no red rays, but is strongest in the violet end of the spectrum, extending far beyond the limits of visibility In that direction and including an abundance of rays that we can photograph, but cannot see. This mercury glow light has made the "wlille you wait photography" of tha pleas use parks a possibility, but it is too ghastly for common use. As the New York Inde- lmportant, and will lead to the discovery that metals are not simply elements but are composed of electrons. It will follow, also, tha). electron aa the new element Is called by Professor Rydberg Is a universal gas, which at all events forms an atmos phere which prwalls throughout our solar system. It is also expected that 'the new dlaoovery will lead to full sclentlfla ex planations of many things which up to Jute have remained doubtful or unex plained, ss, for Instance, the magnetic storms in connection with the sungpot periods, the northern lights, the terrestla. magnetism, etc. Little Stories for Little People Little Urrs. WANT to wear my while dress, mother." ' Myra ' was , being dressed for afternoon. M,l I think your pink one is better for today. Tha rosebud dress. you call It," said mother. "No, I want to wear the white siis." In sisted Myra. "I've a new ribbon for your liair that just matches the rosebud," mother adiled, as she brushed the curly locks. But Myra stood with a cloudy face while she was made clean and sweet in the pretty dress, with the pink ribbon in her hair. Then, without a kiss or a "thank you" for her kind mot lie r, she turned away and went upstairs, saying to her self: "She never let's iu do as I want to. I wish I could find another plats to live. I'm going to try. I'd better take soms of my dolls with me, so that I'll not bs lonesome." Picking up Lady Rose and old black Dir.ih. . she crept softly downstairs and out of the door. Up the street she went a Utile way and stopped before a house. "I think I 11 try tbls one," she said. So she cttmbi the steps and rang the bell. Tli floor opened, and she looked up Into the faee of a lady. "Have you any children?" she asked. "No, dear: what 'would rou like?" sad the lady. "I would like to be' your little girl, and live with you." Myra said. "What will your mother say about HtT" asked the lady. "Oh, she's tired of me, I guei I like you very much; hadn't you better ke-;p me!" "Welt, you may come in," she said. So Myra made herself at home and began housekeeping with ber dulls, in the bay window. The lady had met Myra's mother, and she at ouce sent tier maid to her with a note telling a!out Myra. . ...

Many others which aneady have the underground mileuge will have acquired much of it. The Ideul Is a con duit system reaching every block In the city, with a maximum of trtnch worn. Hut again there are likely to be local con ditions modifying such a scheme. Some times, for example, It may be belter engi neering to go some distance out of the way to avoid blasting a ledge or laying a conduit over a bed of quickrand. A thorough rwltchbourd study must he made in order that the complex system of lines may be properly Interconnect' d. This is bused on the types now prevailing In the lieil system, for tiie engineers recog nize that whatever inty bo eald In favor of the so-cullej "automatic" switchboard for very tiuail exchanges In rural neigh borhoods, it is unlikely to play an Im portant part in the future. .

Building plans follow. These must be so designed ttiat the switchboards and their operators will be adequately housed. Of fices must be provided for an executive force, with departments of tralMc, con struction and maintenance, the size of thefe dtpendlng upon tho probable devel opment of the district, it Is also learned from the number of lines and from a study of the future traffic, about how many operators will be needed. The last named investigation concerns the probable tele phone use of the community, including the growing Importance jif toll communications arid the changing cfianuter of services, the lower grades of which tend to disappear as the telephone habit b comes fixed In a community, Huch studies are an essential part of the culeuisilons, for one operator wilh luO lines at one exchange may be overburdened, whll another with too at an exchange of different type may have Just an ordinary load. Not only is tne number of operators predetermined but the extent of floor space which will be required for their lunch rooms, rest rooms and lockers. 'Tho slxe of the accounting departments is also forecasted, for the number of clerks and bookkeepers needed is pro portioned to the lines Involved and the messages handled. The specifications for exchanges which have thus bten formu lated, sometimes more than a decade in advance, are held in readiness to be turned over, with such emendations as have been necessitated, to an architect when the occasion for building arrives. The theoretical plans, based on a long term of years, do not complete the tele phone census. There then comes up the question of how much of the ultimate study must be utilised right away and how much can be left until demanded by the expanding business. That Involves a second set of elaborate studies, generally based upon a period three years ahead. Considerable sums of money will havj to be set aside out of the savings of the American people in the next few years, in order to give them the telephone ser vice for which they are clamoring.
