A scene on Broadway, New York, in 1890, The same scene after the overhead wires were showing the density of overhead wires replaced by undergroundcables Improvements The history of the telephone is a record of constant improvement. Only by numerous inventions and ceaseless re search for new and better ways has the present standard been reached. Two-score years ago the telephone could hardly carry the human voice across a city. Now it carries it distinctly across this great continent. The once familiar network of overhead wires in large cities has been replaced by systems of underground cables, each cable con taining thousands of slender, sensitive wires. Switchboards, once primitive devices, called upon to handle only a few con nections and limited in their workings, have now become great and precise mechanisms through which the volume and complexity of telephone traffic is handled with mechanical perfection. With the continued growth in the num ber of telephone users, there is a con tinued increase in the problems of speed, accuracy and speech transmission. These are the problems forever before the scientists and engineers of the Bell System; and the solution of these prob lems, in advance of necessity, is the ob jective of this great body of specially trained experts. The Bell System will continue the improvements necessary to maintain its standard of service, which is the best and cheapest telephone service in the world.
