By an act of March 3rd, 1815, so much of the several acts as imposed higher duties on the tonnage of foreign vessels and on the manufactures and productions of foreign nations when imported into the United States in foreign vessels than when imported in vessels of the United States were repealed so far as respected the manufactures and productions of the nation to which such vessels belonged, on the condition that the repeal should take effect only in favor of any foreign nation when the Executive should be satisfied that such discriminating duties to the disadvantage of the United States had likewise been repealed by such nation. By this act a proposition was made to all nations to place our commerce with each on a basis which it was presumed would be acceptable to all. Every nation was allowed to bring its manufactures and productions into our ports and to take the manufactures and productions of the United States back to their ports in their own vessels on the same conditions that they might be transported in vessels of the United States, and in return it was required that a like accommodation should be granted to the vessels of the United States in the ports of other powers. The articles to be admitted or prohibited on either side formed no part of the proposed arrangement. Each party would retain the right to admit or prohibit such articles from the other as it thought proper, and on its own conditions. When the nature of the commerce between the United States and every other country was taken into view, it was thought that this proposition would be considered fair, and even liberal, by every power. The exports of the United States consist generally of articles of the first necessity and of rude materials in demand for foreign manufactories, of great bulk, requiring for their transportation many vessels, the return for which in the manufactures and productions of any foreign country, even when disposed of there to advantage, may be brought in a single vessel. This observation is the more especially applicable to those countries from which manufactures alone are imported, but it applies in great extent to the European dominions of every European power and in a certain extent to all the colonies of those powers. By placing, then, the navigation precisely on the same ground in the transportation of exports and imports between the United States and other countries it was presumed that all was offered which could be desired. It seemed to be the only proposition which could be devised which would retain even the semblance of equality in our favor.
