AUTOMATIC SWITCHBOARDS 415 of the service compels the telephone engineer to embrace readily any available method of improving it. An open mind to the possibilities of new methods is essential. But a mind which is open to those possibilities and closed to the experience of the past is a danger. The 1887 switchboard committee, from whose records I have already freely quoted, discussed the following question : Some systems or organisations of central office apparatus, as we know, are extremely sim...ple in the office and throw the complication outside on to the lines and subscribers' apparatus. Is this advantageous, or should we aim as far as possible to keep such complications in apparatus and operation as seems unavoid- able under the control of the central station ? [and unanimously agreed that] it was decidedly advantageous to keep all the com- plication necessary at a telephone exchange as close to headquarters as possible. This question had no direct relation to automatic apparatus. The comparative merits of varied manual systems only were being considered, but the importance of the decision as a matter of general policy cannot be overlooked.
