With the Government of the Netherlands the mutual abandonment of discriminating duties had been regulated by legislative acts on both sides. The act of Congress of the 20th of April, 1818, abolished all discriminating duties of impost and tonnage upon the vessels and produce of the Netherlands in the ports of the United States upon the assurance given by the Government of the Netherlands that all such duties operating against the shipping and commerce of the United States in that Kingdom had been abolished. These reciprocal regulations had continued in force several years when the discriminating principle was resumed by the Netherlands in a new and indirect form by a bounty of 10 per cent in the shape of a return of duties to their national vessels, and in which those of the United States are not permitted to participate. By the act of Congress of 7th January, 1824, all discriminating duties in the United States were again suspended, so far as related to the vessels and produce of the Netherlands, so long as the reciprocal exemption should be extended to the vessels and produce of the United States in the Netherlands. But the same act provides that in the event of a restoration of discriminating duties to operate against the shipping and commerce of the United States in any of the foreign countries referred to therein the suspension of discriminating duties in favor of the navigation of such foreign country should cease and all the provisions of the acts imposing discriminating foreign tonnage and impost duties in the United States should revive and be in full force with regard to that nation. In the correspondence with the Government of the Netherlands upon this subject they have contended that the favor shown to their own shipping by this bounty upon their tonnage is not to be considered as a discriminating duty; but it can not be denied that it produces all the same effects. Had the mutual abolition been stipulated by treaty, such a bounty upon the national vessels could scarcely have been granted consistently with good faith. Yet as the act of Congress of 7th January, 1824, has not expressly authorized the Executive authority to determine what shall be considered as a revival of discriminating duties by a foreign government to the disadvantage of the United States, and as the retaliatory measure on our part, however just and necessary, may tend rather to that conflict of legislation which we deprecate than to that concert to which we invite all commercial nations, as most conducive to their interest and our own, I have thought it more consistent with the spirit of our institutions to refer the subject again to the paramount authority of the Legislature to decide what measure the emergency may require than abruptly by proclamation to carry into effect the minatory provisions of the act of 1824.
