(4) The Coal Commission already established by the Allies should become an appanage of the League of Nations, and should be enlarged to include representatives of Germany and the other States of Central and Eastern Europe, of the Northern Neutrals, and of Switzerland. Its authority should be advisory only, but should extend over the distribution of the coal supplies of Germany, Poland, and the constituent parts of the former Austro-Hungarian Empire, and of the exportable surplus of the United Kingdom. All the States represented on the Commission should undertake to furnish it with the fullest information, and to be guided by its advice so far as their sovereignty and their vital interests permit. _Tariffs_.--A Free Trade Union should be established under the auspices of the League of Nations of countries undertaking to impose no protectionist tariffs[160] whatever against the produce of other members of the Union, Germany, Poland, the new States which formerly composed the Austro-Hungarian and Turkish Empires, and the Mandated States should be compelled to adhere to this Union for ten years, after which time adherence would be voluntary. The adherence of other States would be voluntary from the outset. But it is to be hoped that the United Kingdom, at any rate, would become an original member. * * * * * By fixing the Reparation payments well within Germany's capacity to pay, we make possible the renewal of hope and enterprise within her territory, we avoid the perpetual friction and opportunity of improper pressure arising out of Treaty clauses which are impossible of fulfilment, and we render unnecessary the intolerable powers of the Reparation Commission. By a moderation of the clauses relating directly or indirectly to coal, and by the exchange of iron-ore, we permit the continuance of Germany's industrial life, and put limits on the loss of productivity which would be brought about otherwise by the interference of political frontiers with the natural localization of the iron and steel industry.
