In formulating an export policy for the period following World War II era, Congress doubtless has been influenced by the post war inflation. The Export Control Act of 1949, in granting the President power to prohibit or curtail the exportation of certain materials, including technical data,[339] made explicit the Congressional intent to protect the domestic economy from the excessive drain of scarce materials and to reduce the inflationary impact of abnormal foreign demand.[340] _Domestic Conservation_: With a view to stabilizing prices and encouraging the conservation of deposits of crude oil situated within the United States Congress in 1935 prohibited the interstate shipment of contraband oil (i.e., oil produced in excess of state imposed quotas).[341] Two different provisions of the Second War Powers Act of 1942 related to conservation of strategic materials. Section 801 empowered the President to direct the Administrator of the Federal Security Agency to assign the manpower of the Civilian Conservation Corps to the extent necessary to protect the munitions, aircraft, and other war industries, municipal water supply, power and other utilities, and to protect resources subject to the hazards of forest fires.[342] Section 1201 permitted the Director of the Mint to vary the metallic composition of five cent pieces to conserve strategic metals.[343] _Priorities and Allocation_: In late May 1941, Congress provided that whenever the President was satisfied that the fulfillment of requirements for the defense of the United States would result in a shortage in the supply of any material for defense or for private account or for export, the President could allocate the material in whatever manner he deemed necessary or appropriate in the public interest and to promote the national defense.[344] This provision was retained in the Second War Powers Act of 1942.[345] In a joint resolution of March 1947 declaring the need for maintenance of a technologically advanced and rapidly expandable domestic rubber-producing industry and for a Congressional study of the problem, Congress provided that in the interim, pending the enactment of permanent legislation, the government should continue allocation, specification, and inventory controls of natural and synthetic rubber.[346] A year later this power was continued. The President was authorized to exercise allocation, specification, and inventory controls of natural rubber and synthetic rubber to insure the consumption of general-purpose synthetic rubber as a part of the estimated total annual consumption of natural rubber.[347]
