With the outbreak of war a striking and artificial change, a totally uneconomic and unnatural factor, came to transform the situation and leave the United States for all practical purposes in contact with only two of her really large customers. We have no merchant marine and cannot therefore avail ourselves of our neutral status to trade with the belligerents. We shall be compelled (for a time at least) to ship in English bottoms to such ports as English ships can make--which will practically be limited to England, France, Portugal, Spain, and the Mediterranean ports. The ordinary commercial roads to Russia through the Baltic are automatically closed by the location of the German fleet, and probably England and France, deprived of other outlets for their own trade, will nearly monopolize the trade with Russia through the Mediterranean and the Black Sea. On the other hand, the mobilization of armies and fleets in Europe will draw millions of men from the field and factories where they have been accustomed to make what we have usually bought. The war will vastly diminish and in many cases stop altogether the stream of imports to the United States. These millions of men in the field and on the sea will not possess most of the economic wants they had in time of peace and will become conscious of many which they usually did not feel. The war will diminish and in many cases entirely stop the stream of ordinary American exports to Europe. Because of the stoppage of the European supply of things we have usually bought of them, and the cessation of a European demand for things we have usually sold to them, the conditions of the home market, both in regard to what we must buy in it, and to what we must sell in it, will be vitally changed. When our present supplies of European importations are exhausted, we shall be obliged to make for each other and buy from each other the things which we happen to be no longer able to import or export. A great readjustment of the economic fabric in the United States will take place if the war lasts longer than a comparatively short time. How long a time that must be will depend entirely upon the sharpness of the break in the economic life of Europe, and the amount of supplies they have on hand, which, as they will not now need them at home, they will be anxious to sell in the United States. Indeed, it would not be surprising if there was for a short time a glut of English and French manufactured goods in the United States market. Europe May Depend On Us.
