The History of the Telephone Part 8

An exhibition instrument was placed in his house, without cost, in 1878, while he was still a member of Congress. Neither Cleveland nor Harrison, for temperamental reasons, used the magic wire very often. Under their regime, there was one lonely idle telephone in the White House, used by the servants several times a week. But with McKinley came a new order of things. To him a telephone was more than a necessity. It was a pastime, an exhilarating sport. He was the one President who really revelled in the comforts of telephony. In 1895 he sat in his Canton home and heard the cheers of the Chicago Convention. Later he sat there and ran the first presidential telephone campaign; talked to his managers in thirty-eight States. Thus he came to regard the telephone with a higher degree of appreciation than any of his predecessors had done, and eulogized it on many public occasions. "It is bringing us all closer together," was his favorite phrase.

To Roosevelt the telephone was mainly for emergencies. He used it to the full during the Chicago Convention of 1907 and the Peace Conference at Portsmouth. But with Taft the telephone became again the common avenue of conversation. He has introduced at least one new telephonic custom a long-distance talk with his family every evening, when he is away from home. Instead of the solitary telephone of Cleveland-Harrison days, the White House has now a branch exchange of its own--Main 6--with a sheaf of wires that branch out into every room as well as to the nearest central.

Next to public officials, bankers were perhaps the last to accept the facilities of the telephone. They were slow to abandon the fallacy that no business can be done without a written record. James Stillman, of New York, was first among bankers to foresee the telephone era. As early as 1875, while Bell was teaching his infant telephone to talk, Stillman risked two thousand dollars in a scheme to establish a crude dial system of wire communication, which later grew into New York's first telephone exchange. At the present time, the banker who works closest to his telephone is probably George W. Perkins, of the J. P. Morgan group of bankers. "He is the only man," says Morgan, "who can raise twenty millions in twenty minutes." The Perkins plan of rapid transit telephony is to prepare a list of names, from ten to thirty, and to flash from one to another as fast as the operator can ring them up. Recently one of the other members of the Morgan bank proposed to enlarge its telephone equipment. "What will we gain by more wires?" asked the operator. "If we were to put in a six-hundred pair cable, Mr. Perkins would keep it busy."

The most brilliant feat of the telephone in the financial world was done during the panic of 1907. At the height of the storm, on a Sat.u.r.day evening, the New York bankers met in an almost desperate conference.

They decided, as an emergency measure of self-protection, not to s.h.i.+p cash to Western banks. At midnight they telephoned this decision to the bankers of Chicago and St. Louis. These men, in turn, conferred by telephone, and on Sunday afternoon called up the bankers of neighboring States. And so the news went from 'phone to 'phone, until by Monday morning all bankers and chief depositors were aware of the situation, and prepared for the team-play that prevented any general disaster.

As for stockbrokers of the Wall Street species, they transact practically all their business by telephone. In their stock exchange stand six hundred and forty one booths, each one the terminus of a private wire. A firm of brokers will count it an ordinary year's talking to send fifty thousand messages; and there is one firm which last year sent twice as many. Of all brokers, the one who finally accomplished most by telephony was unquestionably E. H. Harriman. In the mansion that he built at Arden, there were a hundred telephones, sixty of them linked to the long-distance lines. What the brush is to the artist, what the chisel is to the sculptor, the telephone was to Harriman. He built his fortune with it. It was in his library, his bathroom, his private car, his camp in the Oregon wilder-ness. No transaction was too large or too involved to be settled over its wires. He saved the credit of the Erie by telephone--lent it five million dollars as he lay at home on a sickbed. "He is a slave to the telephone," wrote a magazine writer.

"Nonsense," replied Harriman, "it is a slave to me."

The telephone arrived in time to prevent big corporations from being unwieldy and aristocratic. The foreman of a Pittsburg coal company may now stand in his subterranean office and talk to the president of the Steel Trust, who sits on the twenty-first floor of a New York skysc.r.a.per. The long-distance talks, especially, have grown to be indispensable to the corporations whose plants are scattered and geographically misplaced--to the mills of New England, for instance, that use the cotton of the South and sell so much of their product to the Middle West. To the companies that sell perishable commodities, an instantaneous conversation with a buyer in a distant city has often saved a carload or a cargo. Such caterers as the meat-packers, who were among the first to realize what Bell had made possible, have greatly accelerated the wheels of their business by inter-city conversations.

For ten years or longer the Cudahys have talked every business morning between Omaha and Boston, via fifteen hundred and seventy miles of wire.

In the refining of oil, the Standard Oil Company alone, at its New York office, sends two hundred and thirty thousand messages a year. In the making of steel, a chemical a.n.a.lysis is made of each caldron of molten pig-iron, when it starts on its way to be refined, and this a.n.a.lysis is sent by telephone to the steelmaker, so that he will know exactly how each potful is to be handled. In the floating of logs down rivers, instead of having relays of shouters to prevent the logs from jamming, there is now a wire along the bank, with a telephone linked on at every point of danger. In the rearing of skysc.r.a.pers, it is now usual to have a temporary wire strung vertically, so that the architect may stand on the ground and confer with a foreman who sits astride of a naked girder three hundred feet up in the air. And in the electric light business, the current is distributed wholly by telephoned orders. To give New York the seven million electric lights that have abolished night in that city requires twelve private exchanges and five hundred and twelve telephones. All the power that creates this artificial daylight is generated at a single station, and let flow to twenty-five storage centres. Minute by minute, its flow is guided by an expert, who sits at a telephone exchange as though he were a pilot at the wheel of an ocean liner.

The first steams.h.i.+p line to take notice of the telephone was the Clyde, which had a wire from dock to office in 1877; and the first railway was the Pennsylvania, which two years later was persuaded by Professor Bell himself to give it a trial in Altoona. Since then, this railroad has become the chief beneficiary of the art of telephony. It has one hundred and seventy-five exchanges, four hundred operators, thirteen thousand telephones, and twenty thousand miles of wire--a more ample system than the city of New York had in 1896.

To-day the telephone goes to sea in the pa.s.senger steamer and the wars.h.i.+p. Its wires are waiting at the dock and the depot, so that a tourist may sit in his stateroom and talk with a friend in some distant office. It is one of the most incredible miracles of telephony that a pa.s.senger at New York, who is about to start for Chicago on a fast express, may telephone to Chicago from the drawing-room of a Pullman. He himself, on the swiftest of all trains, will not arrive in Chicago for eighteen hours; but the flying words can make the journey, and RETURN, while his train is waiting for the signal to start.

In the operation of trains, the railroads have waited thirty years before they dared to trust the telephone, just as they waited fifteen years before they dared to trust the telegraph. In 1883 a few railways used the telephone in a small way, but in 1907, when a law was pa.s.sed that made telegraphers highly expensive, there was a general swing to the telephone. Several dozen roads have now put it in use, some employing it as an a.s.sociate of the Morse method and others as a complete subst.i.tute. It has already been found to be the quickest way of despatching trains. It will do in five minutes what the telegraph did in ten. And it has enabled railroads to hire more suitable men for the smaller offices.

In news-gathering, too, much more than in railroading, the day of the telephone has arrived. The Boston Globe was the first paper to receive news by telephone. Later came The Was.h.i.+ngton Star, which had a wire strung to the Capitol, and thereby gained an hour over its compet.i.tors.

To-day the evening papers receive most of their news over the wire a la Bell instead of a la Morse. This has resulted in a specialization of reporters--one man runs for the news and another man writes it. Some of the runners never come to the office. They receive their a.s.signments by telephone, and their salaries by mail. There are even a few who are allowed to telephone their news directly to a swift linotype operator, who clicks it into type on his machine, without the scratch of a pencil.

This, of course, is the ideal method of news-gathering, which is rarely possible.

A paper of the first cla.s.s, such as The New York World, has now an outfit of twenty trunk lines and eighty telephones. Its outgoing calls are two hundred thousand a year and its incoming calls three hundred thousand, which means that for every morning, evening, or Sunday edition, there has been an average of seven hundred and fifty messages.

The ordinary newspaper in a small town cannot afford such a service, but recently the United Press has originated a cooperative method. It telephones the news over one wire to ten or twelve newspapers at one time. In ten minutes a thousand words can in this way be flung out to a dozen towns, as quickly as by telegraph and much cheaper.

But it is in a dangerous crisis, when safety seems to hang upon a second, that the telephone is at its best. It is the instrument of emergencies, a sort of ubiquitous watchman. When the girl operator in the exchange hears a cry for help--"Quick! The hospital!" "The fire department!" "The police!" she seldom waits to hear the number. She knows it. She is trained to save half-seconds. And it is at such moments, if ever, that the users of a telephone can appreciate its insurance value. No doubt, if a King Richard III were worsted on a modern battlefield, his instinctive cry would be, "My Kingdom for a telephone!"

When instant action is needed in the city of New York, a General Alarm can in five minutes be sent by the police wires over its whole vast area of three hundred square miles. When, recently, a gas main broke in Brooklyn, sixty girls were at once called to the centrals in that part of the city to warn the ten thousand families who had been placed in danger. When the ill-fated General Sloc.u.m caught fire, a mechanic in a factory on the water-front saw the blaze, and had the presence of mind to telephone the newspapers, the hospitals, and the police. When a small child is lost, or a convict has escaped from prison, or the forest is on fire, or some menace from the weather is at hand, the telephone bells clang out the news, just as the nerves jangle the bells of pain when the body is in danger. In one tragic case, the operator in Folsom, New Mexico, refused to quit her post until she had warned her people of a flood that had broken loose in the hills above the village. Because of her courage, nearly all were saved, though she herself was drowned at the switchboard. Her name--Mrs. S. J. Rooke--deserves to be remembered.

If a disaster cannot be prevented, it is the telephone, usually, that brings first aid to the injured. After the destruction of San Francisco, Governor Guild, of Ma.s.sachusetts, sent an appeal for the stricken city to the three hundred and fifty-four mayors of his State; and by the courtesy of the Bell Company, which carried the messages free, they were delivered to the last and furthermost mayors in less than five hours.

After the destruction of Messina, an order for enough lumber to build ten thousand new houses was cabled to New York and telephoned to Western lumbermen. So quickly was this order filled that on the twelfth day after the arrival of the cablegram, the s.h.i.+ps were on their way to Messina with the lumber. After the Kansas City flood of 1903, when the drenched city was without railways or street-cars or electric lights, it was the telephone that held the city together and brought help to the danger-spots. And after the Baltimore fire, the telephone exchange was the last force to quit and the first to recover. Its girls sat on their stools at the switchboard until the window-panes were broken by the heat. Then they pulled the covers over the board and walked out.

Two hours later the building was in ashes. Three hours later another building was rented on the unburned rim of the city, and the wire chiefs were at work. In one day there was a system of wires for the use of the city officials. In two days these were linked to long-distance wires; and in eleven days a two-thousand-line switchboard was in full working trim. This feat still stands as the record in rebuilding.

In the supreme emergency of war, the telephone is as indispensable, very nearly, as the cannon. This, at least, is the belief of the j.a.panese, who handled their armies by telephone when they drove back the Russians.

Each body of j.a.panese troops moved forward like a silkworm, leaving behind it a glistening strand of red copper wire. At the decisive battle of Mukden, the silk-worm army, with a million legs, crept against the Russian hosts in a vast crescent, a hundred miles from end to end. By means of this glistening red wire, the various batteries and regiments were organized into fifteen divisions. Each group of three divisions was wired to a general, and the five generals were wired to the great Oyama himself, who sat ten miles back of the firing-line and sent his orders.

Whenever a regiment lunged forward, one of the soldiers carried a telephone set. If they held their position, two other soldiers ran forward with a spool of wire. In this way and under fire of the Russian cannon, one hundred and fifty miles of wire were strung across the battlefield. As the j.a.panese said, it was this "flying telephone" that enabled Oyama to manipulate his forces as handily as though he were playing a game of chess. It was in this war, too, that the Mikado's soldiers strung the costliest of all telephone lines, at 203 Metre Hill.

When the wire had been basted up this hill to the summit, the fortress of Port Arthur lay at their mercy. But the climb had cost them twenty-four thousand lives.

Of the seven million telephones in the United States, about two million are now in farmhouses. Every fourth American farmer is in telephone touch with his neighbors and the market. Iowa leads, among the farming States. In Iowa, not to have a telephone is to belong to what a Londoner would call the "submerged tenth" of the population. Second in line comes Illinois, with Kansas, Nebraska, and Indiana following closely behind; and at the foot of the list, in the matter of farm telephones, are Connecticut and Louisiana.

The first farmer who discovered the value of the telephone was the market gardener. Next came the bonanza farmer of the Red River Valley--such a man, for instance, as Oliver Dalrymple, of North Dakota, who found that by the aid of the telephone he could plant and harvest thirty thousand acres of wheat in a single season. Then, not more than half a dozen years ago, there arose a veritable Telephone Crusade among the farmers of the Middle West. Cheap telephones, yet fairly good, had by this time been made possible by the improvements of the Bell engineers; and stories of what could be done by telephone became the favorite gossip of the day. One farmer had kept his barn from being burned down by telephoning for his neighbors; another had cleared five hundred dollars extra profit on the sale of his cattle, by telephoning to the best market; a third had rescued a flock of sheep by sending quick news of an approaching blizzard; a fourth had saved his son's life by getting an instantaneous message to the doctor; and so on.

How the telephone saved a three million dollar fruit crop in Colorado, in 1909, is the story that is oftenest told in the West. Until that year, the frosts in the Spring nipped the buds. No farmer could be sure of his harvest. But in 1909, the fruit-growers bought smudge-pots--three hundred thousand or more. These were placed in the orchards, ready to be lit at a moment's notice. Next, an alliance was made with the United States Weather Bureau so that whenever the Frost King came down from the north, a warning could be telephoned to the farmers. Just when Colorado was pink with apple blossoms, the first warning came. "Get ready to light up your smudge-pots in half an hour." Then the farmers telephoned to the nearest towns: "Frost is coming; come and help us in the orchards." Hundreds of men rushed out into the country on horseback and in wagons. In half an hour the last warning came: "Light up; the thermometer registers twenty-nine." The smudge-pot artillery was set ablaze, and kept blazing until the news came that the icy forces had retreated. And in this way every Colorado farmer who had a telephone saved his fruit.

In some farming States, the enthusiasm for the telephone is running so high that ma.s.s meetings are held, with lavish oratory on the general theme of "Good Roads and Telephones." And as a result of this Telephone Crusade, there are now nearly twenty thousand groups of farmers, each one with a mutual telephone system, and one-half of them with sufficient enterprise to link their little webs of wires to the vast Bell system, so that at least a million farmers have been brought as close to the great cities as they are to their own barns.

What telephones have done to bring in the present era of big crops, is an interesting story in itself. To compress it into a sentence, we might say that the telephone has completed the labor-saving movement which started with the McCormick reaper in 1831. It has lifted the farmer above the wastefulness of being his own errand-boy. The average length of haul from barn to market in the United States is nine and a half miles, so that every trip saved means an extra day's work for a man and team. Instead of travelling back and forth, often to no purpose, the farmer may now stay at home and attend to his stock and his crops.

As yet, few farmers have learned to appreciate the value of quality in telephone service, as they have in other lines. The same man who will pay six prices for the best seed-corn, and who will allow nothing but high-grade cattle in his barn, will at the same time be content with the shabbiest and flimsiest telephone service, without offering any other excuse than that it is cheap. But this is a transient phase of farm telephony. The cost of an efficient farm system is now so little--not more than two dollars a month, that the present trashy lines are certain sooner or later to go to the junk-heap with the sickle and the flail and all the other cheap and unprofitable things.

CHAPTER VII. THE TELEPHONE AND NATIONAL EFFICIENCY

The larger significance of the telephone is that it completes the work of eliminating the hermit and gypsy elements of civilization. In an almost ideal way, it has made intercommunication possible without travel. It has enabled a man to settle permanently in one place, and yet keep in personal touch with his fellows.

Until the last few centuries, much of the world was probably what Morocco is to-day--a region without wheeled vehicles or even roads of any sort. There is a mythical story of a wonderful speaking-trumpet possessed by Alexander the Great, by which he could call a soldier who was ten miles distant; but there was probably no subst.i.tute for the human voice except flags and beacon-fires, or any faster method of travel than the gait of a horse or a camel across ungraded plains. The first sensation of rapid transit doubtless came with the sailing vessel; but it was the play-toy of the winds, and unreliable. When Columbus dared to set out on his famous voyage, he was five weeks in crossing from Spain to the West Indies, his best day's record two hundred miles.

The swift steams.h.i.+p travel of to-day did not begin until 1838, when the Great Western raced over the Atlantic in fifteen days.

As for organized systems of intercommunication, they were unknown even under the rule of a Pericles or a Caesar. There was no post office in Great Britain until 1656--a generation after America had begun to be colonized. There was no English mail-coach until 1784; and when Benjamin Franklin was Postmaster General at Philadelphia, an answer by mail from Boston, when all went well, required not less than three weeks. There was not even a hard-surface road in the thirteen United States until 1794; nor even a postage stamp until 1847, the year in which Alexander Graham Bell was born. In this same year Henry Clay delivered his memorable speech on the Mexican War, at Lexington, Kentucky, and it was telegraphed to The New York Herald at a cost of five hundred dollars, thus breaking all previous records for news-gathering enterprise. Eleven years later the first cable established an instantaneous sign-language between Americans and Europeans; and in 1876 there came the perfect distance-talking of the telephone.

No invention has been more timely than the telephone. It arrived at the exact period when it was needed for the organization of great cities and the unification of nations. The new ideas and energies of science, commerce, and cooperation were beginning to win victories in all parts of the earth. The first railroad had just arrived in China; the first parliament in j.a.pan; the first const.i.tution in Spain. Stanley was moving like a tiny point of light through the heart of the Dark Continent. The Universal Postal Union had been organized in a little hall in Berne. The Red Cross movement was twelve years old. An International Congress of Hygiene was being held at Brussells, and an International Congress of Medicine at Philadelphia. De Lesseps had finished the Suez Ca.n.a.l and was examining Panama. Italy and Germany had recently been built into nations; France had finally swept aside the Empire and the Commune and established the Republic. And what with the new agencies of railroads, steams.h.i.+ps, cheap newspapers, cables, and telegraphs, the civilized races of mankind had begun to be knit together into a practical consolidation.

To the United States, especially, the telephone came as a friend in need. After a hundred years of growth, the Republic was still a loose confederation of separate States, rather than one great united nation.

It had recently fallen apart for four years, with a wide gulf of blood between; and with two flags, two Presidents, and two armies. In 1876 it was hesitating halfway between doubt and confidence, between the old political issues of North and South, and the new industrial issues of foreign trade and the development of material resources. The West was being thrown open. The Indians and buffaloes were being driven back.

There was a line of railway from ocean to ocean. The population was gaining at the rate of a million a year. Colorado had just been baptized as a new State. And it was still an unsolved problem whether or not the United States could be kept united, whether or not it could be built into an organic nation without losing the spirit of self-help and democracy.

It is not easy for us to realize to-day how young and primitive was the United States of 1876. Yet the fact is that we have twice the population that we had when the telephone was invented. We have twice the wheat crop and twice as much money in circulation. We have three times the railways, banks, libraries, newspapers, exports, farm values, and national wealth. We have ten million farmers who make four times as much money as seven million farmers made in 1876. We spend four times as much on our public schools, and we put four times as much in the savings bank. We have five times as many students in the colleges. And we have so revolutionized our methods of production that we now produce seven times as much coal, fourteen times as much oil and pig-iron, twenty-two times as much copper, and forty-three times as much steel.

There were no skysc.r.a.pers in 1876, no trolleys, no electric lights, no gasoline engines, no self-binders, no bicycles, no automobiles. There was no Oklahoma, and the combined population of Montana, Wyoming, Idaho, and Arizona was about equal to that of Des Moines. It was in this year that General Custer was killed by the Sioux; that the flimsy iron railway bridge fell at Ashtabula; that the "Molly Maguires" terrorized Pennsylvania; that the first wire of the Brooklyn Bridge was strung; and that Boss Tweed and h.e.l.l Gate were both put out of the way in New York.

The Great Elm, under which the Revolutionary patriots had met, was still standing on Boston Common. Daniel Drew, the New York financier, who was born before the American Const.i.tution was adopted, was still alive; so were Commodore Vanderbilt, Joseph Henry, A. T. Stewart, Thurlow Weed, Peter Cooper, Cyrus McCormick, Lucretia Mott, Bryant, Longfellow, and Emerson. Most old people could remember the running of the first railway train; people of middle age could remember the sending of the first telegraph message; and the children in the high schools remembered the laying of the first Atlantic Cable.

The grandfathers of 1876 were fond of telling how Webster opposed taking Texas and Oregon into the Union; how George Was.h.i.+ngton advised against including the Mississippi River; and how Monroe warned Congress that a country that reached from the Atlantic to the Middle West was "too extensive to be governed but by a despotic monarchy." They told how Abraham Lincoln, when he was postmaster of New Salem, used to carry the letters in his c.o.o.n-skin cap and deliver them at sight; how in 1822 the mails were carried on horseback and not in stages, so as to have the quickest possible service; and how the news of Madison's election was three weeks in reaching the people of Kentucky. When the telegraph was mentioned, they told how in Revolutionary days the patriots used a system of signalling called "Was.h.i.+ngton's Tele-graph," consisting of a pole, a flag, a basket, and a barrel.

So, the young Republic was still within hearing distance of its childhood, in 1876. Both in sentiment and in methods of work it was living close to the log-cabin period. Many of the old slow ways survived, the ways that were fast enough in the days of the stage-coach and the tinder-box. There were seventy-seven thousand miles of railway, but poorly built and in short lengths. There were manufacturing industries that employed two million, four hundred thousand people, but every trade was broken up into a chaos of small compet.i.tive units, each at war with all the others. There were energy and enterprise in the highest degree, but not efficiency or organization. Little as we knew it, in 1876 we were mainly gathering together the plans and the raw materials for the building up of the modern business world, with its quick, tense life and its national structure of immense coordinated industries.

In 1876 the age of specialization and community of interest was in its dawn. The cobbler had given place to the elaborate factory, in which seventy men cooperated to make one shoe. The merchant who had hitherto lived over his store now ventured to have a home in the suburbs. No man was any longer a self-sufficient Robinson Crusoe. He was a fraction, a single part of a social mechanism, who must necessarily keep in the closest touch with many others.

A new interdependent form of civilization was about to be developed, and the telephone arrived in the nick of time to make this new civilization workable and convenient. It was the unfolding of a new organ. Just as the eye had become the telescope, and the hand had become machinery, and the feet had become railways, so the voice became the telephone. It was a new ideal method of communication that had been made indispensable by new conditions. The prophecy of Carlyle had come true, when he said that "men cannot now be bound to men by bra.s.s collars; you will have to bind them by other far n.o.bler and cunninger methods."

Railways and steams.h.i.+ps had begun this work of binding man to man by "n.o.bler and cunninger methods." The telegraph and cable had gone still farther and put all civilized people within sight of each other, so that they could communicate by a sort of deaf and dumb alphabet. And then came the telephone, giving direct instantaneous communication and putting the people of each nation within hearing distance of each other. It was the completion of a long series of inventions. It was the keystone of the arch. It was the one last improvement that enabled interdependent nations to handle themselves and to hold together.

To make railways and steamboats carry letters was much, in the evolution of the means of communication. To make the electric wire carry signals was more, because of the instantaneous transmission of important news.

But to make the electric wire carry speech was MOST, because it put all fellow-citizens face to face, and made both message and answer instantaneous. The invention of the telephone taught the Genie of Electricity to do better than to carry mes-sages in the sign language of the dumb. It taught him to speak. As Emerson has finely said:

"We had letters to send. Couriers could not go fast enough, nor far enough; broke their wagons, foundered their horses; bad roads in Spring, snowdrifts in Winter, heat in Summer--could not get their horses out of a walk. But we found that the air and the earth were full of electricity, and always going our way, just the way we wanted to send.

WOULD HE TAKE A MESSAGE, Just as lief as not; had nothing else to do; would carry it in no time."

As to the exact value of the telephone to the United States in dollars and cents, no one can tell. One statistician has given us a total of three million dollars a day as the amount saved by using telephones.

This sum may be far too high, or too low. It can be no more than a guess. The only adequate way to arrive at the value of the telephone is to consider the nation as a whole, to take it all in all as a going concern, and to note that such a nation would be absolutely impossible without its telephone service. Some sort of a slower and lower grade republic we might have, with small industrial units, long hours of labor, lower wages, and clumsier ways. The money loss would be enormous, but more serious still would be the loss in the QUALITY OF THE NATIONAL LIFE. Inevitably, an untelephoned nation is less social, less unified, less progressive, and less efficient. It belongs to an inferior species.

How to make a civilization that is organized and quick, instead of a barbarism that was chaotic and slow--that is the universal human problem, not wholly solved to-day. And how to develop a science of intercommunication, which commenced when the wild animals began to travel in herds and to protect themselves from their enemies by a language of danger-signals, and to democratize this science until the entire nation becomes self-conscious and able to act as one living being--that is the part of this universal problem which finally necessitated the invention of the telephone.
