means Of hempen rope, and are braced | apart by a needle or spar of wood. The
 wireless telephone. just as the wireless
 telegraph, depends upon the projection Of
 electric waves that pass through the at
 mosphere, and solid substances as well
 with the velocity of light. which Is 1sOOOO
 miles a second or more than seven times the circumference of the globe. :
 The mechanical principles upon which the wireless telephone depend seem to be simple enough. although there fs
 great difference of opinion as to the act ual explanation of the phenomena of
 wireless telephony. Speech is the to-rna-
 ton of very rapid complex and ever-varv- ing series Of vibrations of the air and
 their measurement by the nerves of the
 ear. Owing to the resistance of the att
 mosphere. these vibrations grow weaker
 and at last disappear as we get further
 from the source of disturbance. Tels- phony is the art of translating these
 vibrations Of the air into vibrations Of ether whose lesser resistance enables
 them to be carried to great distances for translation into air vibrations again, as only the air vibrations can be measured by the ear In the wireless telephone the air waves are translated into tha vibration Of can electrical dischargs which oscillates the ether.
 One exceptionally valuable feature Q, the wireless telephone, which the United States Government is utilizing as rapidly as possible, is its adaptability to the lighthouse and lightship service. Because of the absence of wire maintenance charges 1t costs no more to talk from shore to lighthouse or a lightship than it would cost to talk between two blocks Of a congested city district. and the light house keeper or lightship people need have no expert training in order to oper- ate the apparatus.
 Government Shows Its Appreciation.
 At every turn the Government has shown its appreciation Of the invention, which, in addition to having been tn- stalled on the thirty odd battleships, cruisers and torpedo-boat destroyers of the Pacific feet before they started o1 their voyage around the world. has also been installed at Fortress Monroe, Mare Island and other army posts.
 SuH another feature of the invention, or rather the benefit that may be derived from it. is for the supplying of music and other forms of entertainment to passengers traveiing on the passenrer vessels A service Of this kind. aided by a huge receiver so that all of the uassen- gers gathered in a large salon could near the music CT operatic airs simu!taae- ously, should prove a most weIco-ns innovation for steamship travellers. t is wichin the range of possibilities. ct an early date, that the traveller by Great Lakes steamer may be able to spend his evenings listening to the voicAs oS Carlso or 2Ielba simultaneously wish the audien- cc5 who see the singers in person a. Covent Garden, London, or the Melro- poiitan or Manhattan Opera Houses in New York.
 With the first great ioEg d'starce wireless station nearing completion ct Toledo. with twenty-Gve other long dis tance stations already contracted for along the lake front. v.tn work going ahead on seventy-Ave small CT shore stations and with fifty odd moro alr ly projected, there i5 reason to ex- pect that, by the time Great Lakes navi- gation opens in the Spring for the season of 1909. the wireless telephone system will be in full operation on the Great Lakes with neasiF 2Co stations in use.
 The central station of the system 7siII be located at Sault Ste Marie. a contract for it's construction already having been let. Chicago. Cleveland. Detroit, sEilwau- kee, Duluth, Buffalo. Erie and Pittsburg are among the cities being provided with iong-dlstance stations, while among other places for which minor stations are either planned or under construction are Sandusky. Lorain.
