The general success of international attempts to allocate mineral supplies during the war suggests the lines along which results might be accomplished during peace. The process is essentially a matter of getting at the facts, and then discussing the situation around a table,—thus eliminating the long delays and misunderstandings arising from the procedure through the older established diplomatic channels. How far such a procedure might be possible without the compelling common interest of war is debatable.
The great powers of the Reparations Committee, previously noted, and of the recently formed European coal commission, already indicate the general nature of the machinery for international control which might be exercised through a league of nations. It is not our purpose to argue for international control or for any specific plan of control, but rather to outline the problem. The question is not an academic one. Various kinds of international control are present facts, and the problem relates to the possibilities of more effective organization of existing agencies.
CONSERVATION IN ITS INTERNATIONAL RELATIONS
The interests of conservation, considering both its physical and its human energy phases (p. 362), seem to call for an international understanding in the use of mineral resources which will result in the minimum hindrance to their free movements along natural channels of trade. The essential fact of the concentration of mineral supplies in comparatively few world localities, and the fact that no nation is supplied with enough of all varieties of minerals, mean that artificial barriers to their distribution cannot but impose unnecessary handicaps on certain localities, which may be anti-conservational from a world standpoint. If the few countries possessing adequate supplies of high-grade ferro-alloy minerals, for instance, were to restrict their distribution by tariffs or other measures, the resulting cost to civilization through the handicapping of the steel industry would be a large one. Or if, for the general purpose of making the United States entirely self-supporting in regard to mineral supplies, sufficiently high import tariffs were imposed on these minerals to permit the use of the low-grade deposits in the United States, earlier
