his own voice come back to him around the world.

 

The immediate long-distance problem is, of course, to talk from New York to the Pacific.

The two oceans are now only three and a half days apart by rail. Seattle is clamoring for a wire to the East. San Diego wants one in time for her Panama Canal Exposition in 1915.

The wires are already strung to San Francisco, but cannot be used in the present stage of the art.

And Vail’s captains are working now with almost breathless haste to give him a birthday present of a talk across the continent from his farm in Vermont.

 

“I can see a universal system of telephony for the United States in the very near future,” says Carty. “There is a statue of Seward standing in one of the streets of Seattle. The inscription upon it is, `To a United Country.’ But as an Easterner stands there, he feels the isolation of that Far Western State, and he will always feel it, until he can talk from one side of the United States to the other. For my part,” continues Carty, “I believe we will talk across continents and across oceans. Why not? Are there not more cells in one human body than there are people in the whole earth?”

 

Some future Carty may solve the abandoned problem of the single wire, and cut the copper bill in two by restoring the grounded circuit.

He may transmit vision as well as speech. He may perfect a third-rail system for use on moving trains. He may conceive of an ideal insulating material to supersede glass, mica, paper, and enamel. He may establish a universal code, so that all persons of importance in the United States shall have call-numbers by which they may instantly be located, as books are in a library.

 

Some other young man may create a commercial department on wide lines, a work which telephone men have as yet been too specialized to do. Whoever does this will be a man of comprehensive brain. He will be as closely in touch with the average man as with the art of telephony.

He will know the gossip of the street, the demands of the labor unions, and the policies of governors and presidents. The psy-chology of the Western farmer will concern him, and the tone of the daily press, and the methods of department stores. It will be his aim to know the subtle chemistry of public opinion, and to adapt the telephone service to the shifting moods and necessities of the times. HE WILL FIT

TELEPHONY LIKE A GARMENT AROUND THE HABITS OF THE

PEOPLE.

 

Also, now that the telephone business has become strong, its next anxiety must be to develop the virtues, and not the defects, of strength.

Its motto must be “Ich dien”—I serve; and it will be the work of the future statesmen of the telephone to illustrate this motto in all its practical variations. They will cater and explain, and explain and cater. They will educate and educate, until they have created an expert public.

They will teach by pictures and lectures and exhibitions. They will have charts and diagrams hung in the telephone booths, so that the person who is waiting for a call may learn a little and pass the time more pleasantly. They will, in a word, attend to those innumerable trifles that make the perfection of public service.

 

Already the Bell System has gone far in this direction by organizing what might fairly be called a foresight department. Here is where the fortune-tellers of the business sit.

When new lines or exchanges are to be built, these men study the situation with an eye to the future. They prepare a “fundamental plan,” outlining what may reasonably be expected to happen in fifteen or twenty years.

Invariably they are optimists. They make provision for growth, but none at all for shrinkage.

By their advice, there is now twenty-five million dollars’ worth of reserve plant in the various Bell Companies, waiting for the country to grow up to it. Even in the city of New York, one-half of the cable ducts are empty, in expectation of the greater city of eight million population which is scheduled to arrive in 1928.

There are perhaps few more impressive evidences of practical optimism and confidence than a new telephone exchange, with two-thirds of its wires waiting for the business of the future.

 

Eventually, this foresight department will expand. It may, if a leader of genius appear, become the first real corps of practical sociologists, which will substitute facts for the present hotch-potch of theories. It will prepare a “fundamental plan” of the whole United States, showing the centre of each industry and the main runways of traffic. It will act upon the basic fact that WHEREVER THERE IS INTERDEPENDENCE, THERE IS BOUND TO BE TELEPHONY; and it will therefore prepare maps of interdependence, showing the widely scattered groups of industry and finance, and the lines that weave them into a pattern of national cooperation.

 

As yet, no nation, not even our own, has seen the full value of the long-distance telephone.

Few have the imagination to see what has been made possible, and to realize that an actual face-to-face conversation may take place, even though there be a thousand miles between. Neither can it seem credible that a man in a distant city may be located as readily as though he were close at hand. It is too amazing to be true, and possibly a new generation will have to arrive before it will be taken for granted and acted upon freely. Ultimately, there can be no doubt that long-distance telephony will be regarded as a national asset of the highest value, for the reason that it can prevent so much of the enormous economic waste of travel.

 

Nothing that science can say will ever decrease the marvel of a long-distance conversation, and there may come in the future an Interpreter who will put it before our eyes in the form of a moving-picture. He will enable us to follow the flying words in a talk from Boston to Denver.

We will flash first to Worcester, cross the Hudson on the high bridge at Poughkeepsie, swing southwest through a dozen coal towns to the outskirts of Philadelphia, leap across the Susquehanna, zigzag up and down the Alleghenies into the murk of Pittsburg, cross the Ohio at Wheeling, glance past Columbus and Indianapolis, over the Wabash at Terre Haute, into St. Louis by the Eads bridge, through Kansas City, across the Missouri, along the corn-fields of Kansas, and then on—on—on with the Sante Fe Railway, across vast plains and past the brink of the Grand Canyon, to Pueblo and the lofty city of Denver. Twenty-five hundred miles along a thousand tons of copper wire! From Bunker Hill to Pike’s Peak IN A SECOND!

 

Herbert Spencer, in his autobiography, alludes to the impressive fact that while the eye is reading a single line of type, the earth has travelled thirty miles through space. But this, in telephony, would be slow travelling. It is simple everyday truth to say that while your eye is reading this dash,—, a telephone sound can be carried from New York to Chicago.

 

There are many reasons to believe that for the practical idealists of the future, the supreme study will be the force that makes such miracles possible. Six thousand million dollars—one-twentieth of our national wealth—is at the present time invested in electrical development. The Electrical Age has not yet arrived; but it is at hand; and no one can tell how brilliant the result may be, when the creative minds of a nation are focussed upon the subdual of this mysterious force, which has more power and more delicacy than any other force that man has been able to harness.

 

As a tame and tractable energy, Electricity is new. It has no past and no pedigree. It is younger than many people who are now alive.

Among the wise men of Greece and Rome, few knew its existence, and none put it to any practical use. The wisest knew that a piece of amber, when rubbed, will attract feathery substances.

But they regarded this as poetry rather than science. There was a pretty legend among the Phoenicians that the pieces of amber were the petrified tears of maidens who had thrown themselves into the sea because of unrequited love, and each bead of amber was highly prized. It was worn as an amulet and a symbol of purity.

Not for two thousand years did any one dream that within its golden heart lay hidden the secret of a new electrical civilization.

 

Not even in 1752, when Benjamin Franklin flew his famous kite on the banks of the Schuylkill River, and captured the first CANNED LIGHTNING, was there any definite knowledge of electrical energy. His lightning-rod was regarded as an insult to the deity of Heaven. It was blamed for the earthquake of 1755. And not until the telegraph of Morse came into general use, did men dare to think of the thunderbolt of Jove as a possible servant of the human race.

 

Thus it happened that when Bell invented the telephone, he surprised the world with a new idea. He had to make the thought as well as the thing. No Jules Verne or H. G. Wells had foreseen it. The author of the Arabian Nights fantasies had conceived of a flying carpet, but neither he nor any one else had conceived of flying conversation. In all the literature of ancient days, there is not a line that will apply to the telephone, except possibly that expressive phrase in the Bible, “And there came a voice.”

In these more privileged days, the telephone has come to be regarded as a commonplace fact of everyday life; and we are apt to forget that the wonder of it has become greater and not less; and that there are still honor and profit, plenty of both, to be won by the inventor and the scientist.

 

The flood of electrical patents was never higher than now. There are literally more in a single month than the total number issued by the Patent Office up to 1859. The Bell System has three hundred experts who are paid to do nothing else but try out all new ideas and inventions; and before these words can pass into the printed book, new uses and new methods will have been discovered. There is therefore no immediate danger that the art of telephony will be less fascinating in the future than it has been in the past. It will still be the most alluring and elusive sprite that ever led the way through a Dark Continent of mysterious phenomena.

 

There still remains for some future scientist the task of showing us in detail exactly what the telephone current does. Such a man will study vibrations as Darwin studied the differentiation of species. He will investigate how a child’s voice, speaking from Boston to Omaha, can vibrate more than a million pounds of copper wire; and he will invent a finer system of time to fit the telephone, which can do as many different things in a second as a man can do in a day, transmitting with every tick of the clock from twenty-five to eighty thousand vibrations. He will deal with the various vibrations of nerves and wires and wireless air, that are necessary in conveying thought between two separated minds. He will make clear how a thought, originating in the brain, passes along the nerve-wires to the vocal chords, and then in wireless vibration of air to the disc of the transmitter. At the other end of the line the second disc re-creates these vibrations, which impinge upon the nerve-wires of an ear, and are
