1DI I T""3I TP fa i 1 u Id u Jo i 1 Coat of Mn(r Trains. 'aw I the economy of operating motor Jdlary and feeding sections of A j-unk railroad. In comparison v . ..o expense of maintaining and work lug similar lines by steam locomoUvea and short trains, have been furnished by the TaftT Vale railroad la Great Britain. The running cost per train mile by motor car equals 4.19 cents, as compared with 10.63 cents by steam locomotive and four carriages of the ordinary type. The cost of repair and renewals of the motor car Is much less than that of the other system, being only 2.92 cents per train mllo, its against 12.44 cents for the steam-propelled train. The wages represent 8.S6 cents in the former case, and 6.34 cents In the latter Instance. Taken on the whole, therefore, It will be observed that the total cost per train mile of the motor car works out at only 10.96 cents, while the cost for the locomotive and carriages is 30 cents per train mile, representing a saving In the case of the former of 19.04 cents, or some 60 per cent cheaper. The economy thereby effected Is ' very appreciable, and represents quite a considerable sum In the course of a yoar's operation. This result Is highly encourag ing and will lead to a more extensive de velopments of the motor-car system of handling short-distance traffic. Already several of the other trunk rail roads of the country. Impressed with the figures obtained by the Taff Vale railroad, are completing arrangements for the intro duction of motor-propelled coaches upon their systems In those sections whore the capacity of the traffic does not sufficiently warrant the employment of a locomotive and train, and wherein the working of the latter at present represents a heavy loss. Telephones (or Farmers. Progressive farmers In different parts of the country are availing themselves of the opportunities that make life worth living In the country In these days. The agri culturists of Genesee county, 'New York, are thoroughly up-to-date. Not content with the benefits of the free rural delivery system, they are enjoying the luxury of a telephone system. It Is of Incalculable benefit to many an Isolated farmer. One man connected with the family of a neighbor by telephone. From this it grew tmtil fifteen farmers connected their homes. Finally they formed a stock com pany and spread the 'phone system throughout the county, making also long distant connections. No one who has once had the telephone will do without it will ingly. Now 200 farmers of the county enjoy the bervice. It enables them to keep con stantly In touch with the markets and to gather news of all kinds, to talk with the grocer, the preacher and In fact to be In instant communication with the outer world. The original fifteen fanners still control the ptock company, and now furnish telephones to their fellows at as low a rate as Is possible. For convenience, and to Insure perfect working1 of the line, the farmers are divided Into sections and the number of telephones In a district Is limited. The telephone and mall eer- . vice and the great Improvements being made along good roads augur well for the future social and business outlook of those who dwell so near to nature. Electric Pan Novelties. The newest thing In electric fans Is a little one that can be attached to any electric light fixture In place of a lamp. Tou simply unscrew a lamp bulb and Screw Into Its place tho little fan and turn the key and the fan starts buzzing. Another new small fan is an electrlo vaporizer, used for spraying perfume, or disinfectant. Still another little elcctrio fan may now be found installed In telephone booths, to make those often confined and clone lit tle compartments more comfortable to the person using the telephone. Many improvements have been made In electric fans since their first Introduction, and they are now made In very great va riety. Now there are fans attached to their support by a swivel, on which the fan can be turned sideways, while the fan motor Is supported on trunnions, on which It can be Inclined to any angle, upward or downward, from the vertical; so that the fan can be made to deliver Its breeses In any desired direction without moving Its support. And there are now fans which as they run revolve continuously on their support, throwing off the air currents In all, di rections. There are also oscillating fans, that swing constantly back and forth within any aro of a circle. There are fans with the fan set In a horizontal plane to deliver the air verti cally where the direct currents would be disturbing, as in dining rooms. Jfew Wireless Telegraph Heeelver. According to LEclalrage Eleetrtque of Paris, a new receiver for wireless teleg raphy has been Invented by a French elec trician, which Is described as follows: "As Is well known, the surface tension at the surface of contact between mercury and acidulated water Is affected by the passage of an electric current from the one to the other. This action may be made to cause the mercury to shift Its position In the tube, and In this way close a local circuit. The apparatus consists simply of a capil ' lary tube partially filled with mercury, having the part above the mercury filled with acidulated water, and having its lower end dipping Into a similar solution. The antenna is connected to a wire lead ing Into the upper part of this tube, and connection is made to the ground from the vessel by means of a wire, good conduc tivity being secured by a layer of mercury on the bottom of this vessel. Two wire from a local signalling circuit are led Into the capillary tube, one being below and the other Just above the normal position of the upper surface of the mercury. When elec tric waves encounter the' antenna, the changes in potential set tip at the surface of the mercury cause tfce latter to rise and, close the local circuit, thus giving the sig nal. A variation of this device consists of two capillary tubes, both sealed into a glass vessel, which Is partially filled with a acidulated water, and covered with a flex ible diaphragm. The diaphragm la then covered by a second vessel from which two rubber tubes are led off. The oscillations of the mercury, due to electric waves, are thus communicated to the diaphragm, and the latter converts them Into audible sig nals which can be heard by applying the tubes to the ear." Electric Wiring- Herniations. After a long delay tho commissioners have at last adopted a code of regulations governing the practice In electric wiring In the District of Columbia based upon an act of congress, . the securing of which was marked by much difficulty. Tho growth of the electrical Installments outstripped tho legal safeguards until It Is known there were some very bad examples of wiring, perhaps highly dangerous. Under the new regulations It will bo possible for the com missioners to overhaul all such bad work and to set up new standards to be reached by all equipments, whether old or new. The electrical science has now progressed to the point at which It Is possible to re duce the danger from this source to an al most negtlgiblo minimum. Enough is known of the character and the tendencies of the eleetrlcal current and of the methods to be adopted for its safe confinement to enable skilled workmen, using proper materials, to wire a residence, store, theater or other largo establishment so that no danger need aver be apprehended. It Is, however, a suggestive fact that whenever a lire of mysterious origin occurs ine first assump tion of the authorities Is that It was caused by electric wires. If such are on the prem ises. For it Is well known that In tba early days of the use of electricity for lighting and power purposes, and even during tha late days of insufficient regulation, sues bad work was done and such poor ma terials were used that the chances of lira being caused in this way are high. Of course much depends upon the thorough ness with which tha regulations ara en forced and upon the spirit in which tha property owners meet them. A Telephone Paradox Explained. An engineer explaining the apparent paradox that the moro business a tele phone company does the less profit Is makes per subscriber, says that the switch board in the exchange is built In sections, each of which contains on an average tha terminals of the lines of 200 Incoming sub scribers. These terminals are called "Jacks," and the panel containing them Is called the answering panel. In addi tion to these 200 incoming Jacks, each section must contain the outgoing Jacks of each subscriber In the exchange. This Is necessary In order that tho operator in each section may be able to connect any of the incoming sulscribers In a section with any other subscriber in the exchange. The panel containing theBe outgoing Jacks is called the multiple panel. On the above basis the switchboard In an exchange of 2,0(4 subscribers would contain ten sec tions, that of a 5,000 exchange, twenty-live sections, and that of a 10,000 exchange fifty sections; consequently each section In exchanges of these capacities would contain respectively 2,200 Jacks, 6,200 Jacks and 10,200 Jacks. The total number of Jacks In a 2,000 exchange Is therefor 22,000. Tha average mind would at once arrive at the conclusion that the total number of Jaoks In a 6,000 switchboard would be two and one-half times that of a 2,000 (or 65,000), and that tba total number in a 10,000 switchboard fives times that of the 2,000. A 5.000 capacity switchboard, how ever, would contain twenty-five sections of 6,200 Jacks each, or a total of 130,000, while a 10,000 capacity switchboard with Its fifty sections of 10,200 Jacks each would contain 610,000 Jacks. For sake of argument we will say that each jack with Its connection and labor represents a cost of IL Kach new subscriber added to a 2.000 exchange has to be "multiplied" Into ten sections, neces sitating ten jacks; but each new subscriber added to a 6,000 exchange has to be "multi plied" Into twenty-five sections, requiring twenty-five Jacks; while each new sub scriber added to s 10,000 exchange has to be multiplied into fifty sections, requiring fifty Jacks. Now, as to the number of "hello girls" necessary to operate exchanges of the size mentioned: While one operator can take care of each section of a 2,000 capacity switchboard, the larger exchanges require three or more operators per section, besides assistants, relief operators and monitors. It Is, therefore, evident that a company starting out with 2,000 subscribers, on a basis of say $50 per year for service, makes less profit on each 200 subscribers added; and such Is the decrease In the profit as the exchange mounts up to 5,000 or 10,000 that the company must either Increase its rates or quit. One of the most Interesting exhibits In the St. Louis exposition Is that of the Invention of a German named Kallcr, who has succeeded In eliminating the mul tiple feature, not only from automatic prac tice, but also from present manual prac tice. Elect rte Heatlotr and Cooking; As to the cost of electric domestic heat ing and cooking, an authority makes the point that while low rates for current will be necessary to popularize the electrlo method generally. It has a wide field at higher cost than Its competitor, gas, and for the same reasons that gas has had such general recognition, although it costs more than coal. Klectrlc lighting, too. It may be called to mind, costs more than gas dirsctly, bnt Its many advantages, such as cleanliness, convenience and safety, ore gains that aro now appreciated to have a cash value. In houses where the work is In the hands of the Ignorant "help," there Is not a good field today for electric cook ing, but In (he home whore the mistress la the cook, entirely, or In part, and In small houses In suburban towns and the smaller cities, the field Is wider. Tha freedom from heat, offensive products of combustion and leaky valves; the Inevitable soot, dirt and chance explosions Incident to gas and the absence of all cooking devices between periods of use. owing to the portability of electric healers, are tangible advantages In addition to the more perfect results ob tained. In thousands of homes gas Is used as an auxiliary to the coal range for soma of the lighter meals at all seasons, and for much of the general cooking In summer, when the range Is not required to be put In oommh'sion for other purposes. For all such purposes, this authority states, elec tric cooking Is not only possible but mora attractive and satisfactory, all things con sidered, than any other method. Electric lrimn(lTri, Evidently the electric locomotive Is soon to appear on tho steam railroad for general use, as well as for hauling trains through tunnels and where smoke and cinders be come partlcul:irly objectionable. According; to a report published In New York, the New York Central company Is having several big electric locomotives constructed on plans prepared by a commission of railroad and electrical expert These ma chines will weigh nearly 190,000 pounds each, and will possess on Indicated horse power of from 2,200 to 2.SC0, or considerably more than the big steam locomotives which haul the company's fast express trains. It is understood that while these huga electric motors will be available for any service on any part of tho Central's sys tem, they will be used st first on tha Hudson river division, and presumably In hauling express trains, for they will have a poBFlble speed of seventy-five miles an hour. Why Ills INoe Was Red. A man fom Mexico, Jacques Forbes by name, at the Gait house last night, claims to have a typical mother-in-law. Inflicted with that strange and almost universal womanly failing of asking promiscuous questions. "It was only a few weeks ago," said Mr. Forbes, "that, a dilapidated-looking tramp, with a long, strikingly red nose, one of those all-abluzo noses applied at the back door of my mother-in-law's homo for food. " 'Sure,' sold my mother-in-law, In re sponse to his request for food, 'I'll give you something to eat, but my good man, won't you please tell me what makes your nose so very red? " 'Not the least objection, madam,' re plied the tramp, 'it's simply blooming With pride that it doesn't stick Itself Into other people's business. Good day, madam.' "Louisville Herald. A Bachelor's Reflections Everybody would have a good deal mora money If It wasn't any use to him. The best way to make a girl understand bow much you love her Is to tell her how lovable she Is. There doesn't Sfem to be much sense In, the way a girl's hair musses up Just be cause you are kissing her. A bachelor can save a lot of money by spending so much on horse races that be can't afford to get married. A man thinks he Is ambitious to go out Into the world and do something when bo is only anxious to get a vacation from home. New York Press.
