Since the invention of the Morse system more than fifty years ago, telegraphy has grown by law of natural evolution to meet the demands of an increasing business. The Morse system has been the measure of the potential of the telegraph wires and of the operator. To handle a continuously increasing business, telegraph managements have been compelled to stretch annually new copper wires and to employ new operators, because the present wire systems have been worked continuously to their capacity and operators to their highest efficiency under the conditions imposed by Morse methods. It is evident that this indefinite extension of wire systems and the force of operators involves the consequent investment of enormous capital and increases indefinitely annual maintenance charges.
