The committee reports that it will be necessary to continue for a considerable period after the war some portion of the control of home and foreign trade in order to secure adequate supplies of foodstuffs and raw material. It does not regard it as practical to attempt to make the empire self-supporting in respect of numerous raw materials. It notes that the Board of Trade already has set up a committee to investigate the question of the supply of cotton and it recommends special inquiries as regards each commodity. "The object to be kept in view should be that the empire may be capable in an emergency of being independent in respect of the supply of every essential commodity of any single foreign country." The committee advises against the exclusion of foreign (other than present enemy) capital from sharing in the development of the empire's resources, but recommends: (a) Complete disclosure, as far as is practicable, of the extent of foreign holdings in any particular case. (b) That mineral and other properties are not secured by foreign concerns in order to prevent the development of those properties, and to check competition in supply; and (c) That in the case of commodities of great imperial importance, the local Government concerned should have some measure of control over the working of the properties. These principles, if accepted, should be brought to the notice of the Governments of other parts of the empire, with a view to the adoption of a uniform policy. ALIENS IN BUSINESS The committee expresses the opinion that it would not be desirable to impose special restrictions against the participation of aliens in commercial and industrial occupations. It recommends, however, that such occupations as pilot and patent agent should be confined to British-born subjects, and suggests that foreign commercial travelers operating in the United Kingdom should be registered and hold licenses, that the registration of title to property should be compulsory, and that such registration should involve a declaration of the nationality of the owner. The committee deems it unwise to restrain the establishment or the continuance of agencies or branches of foreign banks or insurance companies in the United Kingdom, but foreign insurance companies should be required to make a deposit proportionate to the business done. Foreign banks should be required to pay the income tax. The committee considers it necessary to impose special restrictions on the subjects of enemy countries, and that this can best be done by means of stringent permit and police regulations, but it does not believe that attempts should be made to prevent enemy subjects from establishing agencies or holding interests in commercial or industrial undertakings. A plan for the maintenance and development of industries essential to national safety, called "Key Industries," is proposed, as follows:
