It will be seen that the production of this necessity for the military establishments of our country and its allies during the war was reduced by more than 96 per cent. This, however, does not tell the full story of the loss. All rubber imported into the United States from Mexico can be brought by railroad. All other rubber imported required the use of ocean tonnage which was so precious after our entrance into the war. As the result of the destruction of rubber production in Mexico, many millions of pounds, to offset the loss, had to be brought in by the use of much maritime tonnage which might, of course, have been used for other most necessary purposes.
