Book excerpt: Excerpt from Annual Report of the Directors of American Telephone and Telegraph Company to the Stockholders for the Year Ending December 31, 1913 Type after type of cable was installed only to be withdrawn in a few years and replaced by something better. By 1887 the introduction of the twisted pair underground conductor began. This meant the abandonment of the entire underground plant of the Bell System and the intro duction of the new type, without which the telephone system as we know it to-day would be an impossibility. Millions of dollars were spent in this construction and reconstruction and experimental work. By 1902 the art had so far advanced by the use of the Pupin loading coils and other improvements, that a loaded cable for subur ban service was successfully installed between New York and Newark. By 1905 we had a loaded cable twenty miles long ex tending from New York in the direction of Philadelphia, and by 1906 a cable 90 miles long was successfully operated between those two cities, but in the then state Of the art this cable could not be used beyond Philadelphia or New York. By 1911 our experiments, researches, and improvements in manufacture had SO advanced that we were enabled to design an underground cable, capable of giving a satis factory conversation between Washington and Boston. By 1912 a section of this new cable was laid from Washington to Philadelphia, there connecting with the earlier type of cable to New York. During 1913 a section of the new cable was laid between New Haven and Providence, connecting at New Haven to an earlier type of cable extending to New York, and connecting at Providence to an earlier type extending to Boston.
