Those were hard times for Vail and the partners back of him. The telephone war had cut the price of service to a point where neither company could show a profit. Bell, now married, returned from England with word that he had been unable to establish the telephone business there, and that he must have a thousand dollars at once to pay his most pressing debts. He was ill, and he wrote from the Massachusetts General Hospital, “Thousands of telephones are now in operation in all parts of the country, yet I have not yet received one cent from my invention. On the contrary, I am largely out of pocket by my researches, as the mere value of the profession that I have sacrificed during my three years’ work amounts to twelve thousand dollars.”

At this juncture a young Bostonian named Francis Blake wrote to Vail, announcing that he had invented a transmitter that was the equal of Edison’s, and offering to sell it for stock in the company. The purchase was made, and the claim of the inventor proved true. The Bell telephone was again as good as that of the Western Union Company. A new company, called the National Bell Telephone Company, was organized, with a capital of $850,000, and Colonel Forbes of Boston became its first president.

There have been few patent struggles to compare with that which was waged over the telephone. McCormick fought for years to uphold his rights to the invention of the reaper, but he fought a host of competitors, and the warfare was of the guerrilla order. The Bell Company fought alone against the Western Union, and it was a struggle of giants. The Western Union was certain that it could find patents antedating Bell’s, and it went on that assumption, even after its own expert had reported, “I am entirely unable to discover any apparatus or method anticipating the invention of Bell as a whole, and I conclude that his patent is valid.” It claimed that Gray was the original inventor, and instructed its lawyers to bring suits against the Bell Company for infringing on Gray’s patents.

The legal battle began in the autumn of 1878, and continued for a year. Then George Gifford, the leading counsel for the Western Union, told his clients that their claim was baseless, and advised that they come to a settlement. The Western Union saw the wisdom of this course, and went to the Bell Company with an offer of compromise. An agreement was finally reached, to remain in force for seventeen years, and the terms were that the Western Union should admit that Bell was the original inventor, that his patents were valid, and should retire from the telephone business. On the other side, the Bell Company agreed to buy the Western Union telephone system, to pay them a royalty of twenty per cent. on all their telephone rentals, and to keep out of the telegraph business.

That ended the great war. It converted a powerful rival into an ally, it gave the Bell Company fifty-six thousand new telephones in fifty-five cities, and it made that company the national system of the United States. In 1881 there was another reorganization; the American Bell Telephone Company was created, with a capital of six million dollars. The following year there was such a telephone boom that the Bell Company’s system was doubled, and the gross earnings reached more than a million dollars.

The four men who had taken hold of Bell’s invention in its infancy and brought it to maturity were ready to surrender its care into the hands of the able business men who headed the Bell Company. Sanders sold his stock in the company for a little less than a million dollars, Watson, when he resigned his interest, found himself sufficiently rich to build a ship-building plant near Boston and employ four thousand workmen to build battle-ships. Gardiner G. Hubbard retired from active business life, and transferred his remarkable energy to the affairs of the National Geographical Society. Bell had presented his stock in the company to his wife on their wedding-day, and he now took up afresh the work of his boyhood and youth, the teaching of deaf-mutes. But he was no longer unheeded nor unrewarded. In 1880 the government of France awarded him the Volta prize of fifty thousand francs and the Cross of the Legion of Honor. With the Volta prize he founded the Volta Laboratory in Washington for the use of students. In Washington he has made his home, and there scientists of all lands call to pay their respects to the patriarch of American inventors.

Shortly after the first appearance of the telephone at the Centennial Exposition men were accustomed to laugh at the new invention, and call it a freak, a scientific toy. Its mechanism was so incomprehensible to most people that they refused to regard it seriously. A Boston mechanic expressed the general ignorance when he stoutly maintained that in his opinion there must be “a hole through the middle of the wire.” And the telephone is still to most people a mystery, far more so than the telegraph or the incandescent light or the other uses to which electricity has been put. It is one thing to send a message by the mechanical process of dots and dashes made by breaking and joining a current. It is quite another to reproduce in one place the exact inflection, tone, and quality of a voice that is speaking hundreds of miles away, across rivers and mountains. There is real magic in that, the wonder that might be found in a Genii’s spell in the Arabian Nights. How can people be blamed for laughing at such pretensions, and believing that even if such a thing were true it was more fit for an exposition than for public use?

Yet this thing of magic has outdistanced every other mode of communication. It is estimated that in the United States as many messages are sent by telephone as the combined total of telegrams, letters, and railroad passengers. The telephone wires are eight times greater than the telegraph wires, and their earnings six times as great. It is true that the telephone is vastly more used in America than in other parts of the world, and yet it is figured that in the world at large almost as many messages are now telephoned as are sent by post.

And the mystery of the telephone grows no less the more one studies it. You speak against a tiny disc of sheet-iron, and the disc trembles. It has millions and millions of varieties of trembles, as many as there are sounds in the universe. A piece of copper wire, connected with an electric battery, stretches from the disc against which you have spoken to another disc miles and miles away. The tremble of your disc sends an electric thrill along the wire to that other disc and makes it tremble exactly as yours did. And that trembling sounds the very note you spoke, the very note in millions of possible notes, and as accurately as if the sound wave had only traveled three feet through clear air. That is what happens when you telephone, but when you realize it the mystery gains rather than decreases.
