Measures are being taken to modernize, popularize, and speed up the Inland Telegraph Service. Instruments and machinery new to the Service have been introduced with unprecedented rapidity. Teleprinters, typewriters, copper-oxide rectifiers, rotary convertors, thermionic valves, voice-frequency signalling, and band conveyors, are the main features of the reorganized system. Each of these items- receives notice in the paper. Panel-mounted apparatus is a novel departure that has created considerable interest among telegraph engineers. In the circumstances it may be some time before technical literature giving a comprehensive account of the methods employed is available; the paper, therefore, describes the standard equipment in detail. A new class of technical officers for testing and maintenance duties has been created; the personnel is chosen from the general body of telegraph operators and receives training in an engineering school.A telegraph exchange service, “ The Telex,” has been made available to subscribers to the telephone service, for whom the necessary apparatus is installed on rental terms. The renters are able to transmit and receive printed communications in addition to the usual telephone facilities. They may also transmit messages to the Post Office, creating a new class of traffic designated “Printergrams.” We have telegrams, phonograms, and now printergrams. The supply of underground conductors is now more than adequate for the requirements of the public services, and channels of communication are offered to the public, on rental terms, for the purpose of private-wire circuits. The ascertained results of the reorganization, still far from complete, are in the direction of increased stability and accuracy. In addition, recent figures show an improvement in the financial position. In another direction there is evidence that the changes have not been entirely unfruitful as regards increased comfort and convenience of the army of workers who staff the telegraph instrument rooms of this country.
