 Little Rock, March 23.-Almost overnight we have awakened to the fact that the most marvellous inven- tion of all time is in practical use | all over the world. For several years 1t has been known that it is pos sible to transmit sound without wires and some remarkable instances are on record of experiments in the field of l radio transmission.
 But, before the public is scarce aware, the world finds itself in an era of marvels that is almost unbelieve- able even by those of middle age who have witnessed the development of the moving picture, the wireless tele- graph, the photograph, the electrical light, the airplane, radium and many other marvels which were consider ed wholly in the realm of the fan tastic and the impossible 50 years ago.
 There have already been a number of successful experiments in Little Rock, Pine Bluff, Fort Smith and other places in Arkansas in radio telephony. It is predicted that with in a year or more, when the system has been perfected, it will be possible to have installed in any home in the state or elsewhere, receiving sets through which the owners may re- ceive news of any character, enter tainments, speeches or concerts of any kind broadcasted from remote cen- ters.
 One night last week 20c members of the First Christian church were assembled in the basement of the church in Little Rock and heard con- certs and speeches which originated thousands of miles away. A single 50 foot wire stretched above the roof of the church acted as an agency to intercept the sound waves which were carried through wire into the in- strument in the basement and there disseminated audiby by means of a photograph horn. During half hour demonstration, che audience sat spellbound as they listened to t"Ave Maria" sung by Marie Rappold in Newark, N. J.; "The Rosary" sung by an artist in Pittsburgh, Pa., and an address on modern chemistry and the song Danny Deever" broadcasted from the office of the Detroit News in Detroit, Mich. The operator of the apparatus turned the dial of the ma chine until he tuned in" on the sound waves sent out by the various stations and then the sounds of what ever nature were clear and audible throughout the room. Only a few nights before the same apparatus had received an address delivered by Will liam Jennings Bryan in Pittsburgh, Pa. In the midst of his speech, his audience in Arkansas, as we'll as hun dreds of thousands of others who were listening in' all over the union, heard the great commoner say, With in a few days l expect to visit that wonder state of the union, Arkansas" The well known, resonant tones of Americas most eminent private cit izen were easily distinguished and un consciously his far-away audience broke int applause when he took oc- casion to compliment Arkansas.
 The device is still more or less in an incomplete state, although the period of experimentation has passed. All that remains is for inventors to overcome the harshness and inter ruptions and the metallic sound which all remember in connection with the early models of the phonogroph. That this can be done, there is no doubt, through the medium of ampli- fiers, wave controllers, and devices that will overcome static interfer- ference.
 The possibilities of the invention are limitless. For instance Within short time it will be possible for newspaper offices, public halls, busi- ness houses or private residences to have their individual receiving sets which may be tuned in' on broad casting apparatus in Little Rock and every play in baseball game can be announced; a concert may be heard; an entire church service, including prayer, song and sermon may be re- produced; news of any kind may be disseminated.
 Radio enthusiasts all over Arkan- sas are forming clubs, both amateur and professional, to experiment with the new system of sound transmission. It is rapidly passing the period of be- ing a hobby or an idle amusement and is entering the field of practical busi- ness life.
