It is characteristic of the best telephone management that while it cannot always perfectly forecast the direction of immediate growth, it should be built far enough ahead of present requirements to have a pair of wires ready for each new customer. The fact that New York and other large American cities have a considerable investment in telephone plant constructed to meet a prospective demand, is the price which must be paid by any telephone management which really supplies the wants of the American people. Every additional subscriber that is connected with the system, requires sooner or later an outlay of new capital for his proportionate share of the whole plant, including equipment, wires, poles, cables, switchboards and real estate. In America the new subscriber finds his need anticipated and the facilities provided. [Illustration: THIS PRIVATE SWITCHBOARD, IN ONE AMERICAN HOTEL, IS LARGER THAN MANY A SWITCHBOARD ABROAD, WHICH SERVES A WHOLE CITY] It is characteristic of private management that plans can be made for the future with reasonable assurance that the necessary funds will not be arbitrarily withheld, or that the work of the past will not be ruthlessly cast aside. Another factor of telephone service in America is promptness. Local connections are made in a few seconds. In the case of interurban and long-distance calls, to prevent the long waiting for a turn, which abroad sometimes is a matter of hours, the American engineer provides enough long-distance trunks, so that, except in cases of accident, customers at the busiest times of the day are connected with distant points without delay. The First Transcontinental Line. The opening of the first transcontinental line between New York and San Francisco on January 25, 1915, was an epoch-making event in telephone history. The line is 3,400 miles long. It crosses thirteen states; it is carried on 130,000 poles. Four hard-drawn copper wires, .165 of an inch in diameter, run side by side over the entire distance, establishing two physical and one phantom circuit. The ordinary telephone connection consists of two wires technically called a telephone circuit, each wire constituting one “side” of the circuit. A phantom circuit is a circuit superimposed on two ordinary circuits by so connecting the two wires or “sides” of each ordinary circuit that they can be used as one side of the phantom circuit. In this way three practical talking circuits can be obtained from four wires. One mile of single wire used in the transcontinental line weighs 435 pounds, the weight of the wires in the entire line being 5,920,000 pounds, or 2,960 tons.
