The policy of the United States in their commercial intercourse with other nations has always been of the most liberal character.  In the mutual exchange of their respective productions they have abstained altogether from prohibitions; they have interdicted themselves the power of laying taxes upon exports, and when ever they have favored their own shipping by special preferences or exclusive privileges in their own ports it has been only with a view to countervail similar favors and exclusions granted by the nations with whom we have been engaged in traffic to their own people or shipping, and to the disadvantage of ours.  Immediately after the close of the last war a proposal was fairly made by the act of Congress of March 3rd, 1815, to all the maritime nations to lay aside the system of retaliating restrictions and exclusions, and to place the shipping of both parties to the common trade on a footing of equality in respect to the duties of tonnage and impost.  This offer was partially and successively accepted by Great Britain, Sweden, the Netherlands, the Hanseatic cities, Prussia, Sardinia, the Duke of Oldenburg, and Russia.  It was also adopted, under certain modifications, in our late commercial convention with France, and by the act of Congress of January 1st, 1824, it has received a new confirmation with all the nations who had acceded to it, and has been offered again to all those who are or may here after be willing to abide in reciprocity by it.  But all these regulations, whether established by treaty or by municipal enactments, are still subject to one important restriction.

The removal of discriminating duties of tonnage and of impost is limited to articles of the growth, produce, or manufacture of the country to which the vessel belongs or to such articles as are most usually first shipped from her ports.  It will deserve the serious consideration of Congress whether even this remnant of restriction may not be safely abandoned, and whether the general tender of equal competition made in the act of January 8th, 1824, maynot be extended to include all articles of merchandise not prohibited, of what country so ever they may be the produce or manufacture.  Propositions of this effect have already been made to us by more than one European Government, and it is probable that if once established by legislation or compact with any distinguished maritime state it would recommend itself by the experience of its advantages to the general accession of all.

The convention of commerce and navigation between the United States and France, concluded on June 24th, 1822, was, in the understanding and intent of both parties, as appears upon its face, only a temporary arrangement of the points of difference between them of the most immediate and pressing urgency.  It was limited in the first instance to two years from January 10th, 1822, but with a proviso that it should further continue in force ’til the conclusion of a general and definitive treaty of commerce, unless
