In appearance, Enos M. Barton closely resembles ex-President Eliot, of Harvard. He is slow in speech, simple in manner, and with a rare sagacity in business affairs. He was not an organizer, in the modern sense. His policy was to pick out a man, put him in a responsible place, and judge him by results. Engineers could become bookkeepers, and bookkeepers could become engineers. Such a plan worked well in the earlier days, when the art of telephony was in the making, and when there was no source of authority on telephonic problems. Barton is the bishop emeritus of the Western Electric to-day; and the big industry is now being run by a group of young hustlers, with H. B. Thayer at the head of the table. Thayer is a Vermonter who has climbed the ladder of experience from its lower rungs to the top. He is a typical Yankee--lean, shrewd, tireless, and with a cold-blooded sense of justice that fits him for the leadership of twenty-six thousand people. So, as we have seen, the telephone as Bell invented it, was merely a brilliant beginning in the development of the art of telephony. It was an elfin birth--an elusive and delicate sprite that had to be nurtured into maturity. It was like a soul, for which a body had to be created; and no one knew how to make such a body. Had it been born in some less energetic country, it might have remained feeble and undeveloped; but not in the United States. Here in one year it had become famous, and in three years it had become rich. Bell's invincible patent was soon buttressed by hundreds of others. An open-door policy was adopted for invention. Change followed change to such a degree that the experts of 1880 would be lost to-day in the mazes of a telephone exchange. The art of the telephone engineer has in thirty years grown from the most crude and clumsy of experiments into an exact and comprehensive profession. As Carty has aptly said, "At first we invariably approached every problem from the wrong end. If we had been told to load a herd of cattle on a steamer, our method would have been to hire a Hagenbeck to train the cattle for a couple of years, so that they would know enough to walk aboard of the ship when he gave the signal; but to-day, if we had to ship cattle, we would know enough to make a greased chute and slide them on board in a jiffy." The telephone world has now its own standards and ideals. It has a language of its own, a telephonese that is quite unintelligible to outsiders. It has as many separate branches of study as medicine or law. There are few men, half a dozen at most, who can now be said to have a general knowledge of telephony. And no matter how wise a telephone expert may be, he can never reach perfection, because of the amazing variety of things that touch or concern his profession.
