Show THE SATT LAKE TRIBUTE, SUNDAY MORXINfi, JUNE 6 By Frank Stockbridge Words Across the Sea repaid for all the labor i have expended upon it" That service to humanity will always be radio's exclusive field. Ships keep on their courses by radio compass, determine their positions and find their way to port by radio direction signals. In the air, they are guided to landing fields by radio beacons, talk with earth from a mile high. Dr. E. T. W. Alexan-derso- n In Schenectady showed me his radio sounding device, automatically telling the pilot his altitude by a reflected radio wave. Radio guides airplanes without a pilot; we can picture commercial airways of the new world traversed by freight planes with no human hand at the controls.

So far as that goes, the only demonstration of actual- television, as we understand the term, was made over telephone - 1 Marconi's first transatlantic radio message, in 1903, was the first step in our modern march of leading to our present network of wire and wireless channels and to the vision of cveii greater ' in the future.

A short time ago In Bchenectady a dozen men grouped around a microphone chatted bt radio with Australia, half a world away, with Java listening in to the spoken words and occasionally taking part In the conversation. "The wire are doomed, ay say. But wires the unthinking and cable, for telegraphy and telephony, have multiplied faster since the war than ever before and are still pushing their line Into the corner of the earth.

Televtsion as yet Is not much more than a laboratory experiment; when It will get out of the laboratories and into general use, nobody knows. Sending a picture over the wires or by radio is a simple trick. It is being done and paid for every day. Sending a motion picture Is a good deal more of a trick. Or. Herbert E. Ives, probably the world's foremost investigator in the field of optics, has done it experimentally by wire; I have been unable to learn that it ha been done by radio at all. Television seeing what Is actually happening at the other end of the circuit and not merely a photograph of it ha been achieved in an extremely limited way. on a very small scale, experimentally, by means of both wire and radio. Observers in New York a little while ago saw Herbert Hoover' lips move as he talked into the telephone In Washington: the Image was three' or four inches across less than life size.

It with the human eye. Compared with the ear. the eye it an" inefficient organ.. The ear selects a single tone, hkrmony or sequence of sounds from amid a confusion ol noises. The eye must get its Impression clearly and. alone, in a single glance. To send a picture over an electric circuit you must reflect to a photoelectric cell the ligHt from the object to be pictured. The cell Is. In effect, an electric Ught bulb which works backward. In an ordinary blub you put in light and get out electric current. The amount of current flowing througtj the radio or wire circuit depends upon the amount of llghUreflected to the cell from the object that is being pictured. At the other end the current is translated back into light again, and it is easy enough. Illuminating the original by a moving pencil of powerful light, to make a similar moving light reflect all the shadows and high lights upon a photographic film. But that process takes time more time than the eye will adapt Itself to a minute or more to transmit even a small photograph.

One principle stands out clearly: Whatever ccn be done by radio can be done better by wires, wherever it and whenever it pays to run wires or it is physically possible to run them. In the new world of tomorrow we shall see radio occupy only the fields which the wires can't occupy; they are crowding today close upon radio' heels, waiting to sefee each field as soon as the growth of population and wealth makes it economical to do so. In their, laboratories research workers have discovered how to make a telephone cable which will carry the voice by wire to England: when the traffic becomes heavy enough to pay the interest on its cost, the telephone cable will be laid.
