The defense emergency has, ofcourse, tremendously stimulated thework of the Bell System engineeringgroups. An immediate survey wasmade in 1939, based on a study of ma-terials particularly used in the BellSystem, and a list of critical materialsdeveloped. The list initially consistedmainly of critical materials which werepurchased outside of the United States,or the sources of which were beyondcontrol. Looking to the future. WesternElectrics engineers are consideringthe use of sisal and ixtle, fibrous ma-terials readily obtainable in this hemi-sphere, in place of jute and burlap forcable construction. In compliance with an order of theDirector of Priorities and in view ofthe necessity of conserving the supplyof rubber. Western Electric plans agradual reduction of its use of cruderubber which will reach a level of 19^1 Telephones and Defense 199

Even Sweepings Are Collected Gathered in railroad cars, trucks, operation departments, and from other System sources, this scrap will charge a blastfurnace at Nassau Smelting and Refining Company, and will yield copper to be rolled and drawn into telephone wire more than 20 per cent by the end ofthe year. This saving will be accom-plished chiefly by the use of more re-claimed rubber in rubber compoundand reduction in the use of hard rub-ber by the judicious use of materialshaving similar properties. For the purposes of the emergency,temporary manufacturing informationpermits the manufacturing departmentto proceed with rapid introduction ofsubstitutes. Because of the many fac-tors involved—processing, engineer-ing, materials and new procedures—manufacturing costs inevitably willrise as a direct result of the use ofsubstitute materials. Nor are manu-facturing conditions relieved by the fact that the defense program hasgreatly stimulated current telephonebusiness, as well as plant ex
