It affords me peculiar satisfaction to state that the Government of Spain has at length yielded to the justice of the claims which have been so long urged in behalf of our citizens, and has expressed a willingness to provide an indemnification as soon as the proper amount can be agreed upon. Upon this latter point it is probable an understanding had taken place between the minister of the United States and the Spanish Government before the decease of the late King of Spain; and, unless that event may have delayed its completion, there is reason to hope that it may be in my power to announce to you early in your present session the conclusion of a convention upon terms not less favorable than those entered into for similar objects with other nations. That act of justice would well accord with the character of Spain, and is due to the United States from their ancient friend. It could not fail to strengthen the sentiments of amity and good will between the two nations which it is so much the wish of the United States to cherish and so truly the interest of both to maintain. By the first section of an act of Congress passed on July 13th, 1832 the tonnage duty on Spanish ships arriving from the ports of Spain previous to October 20th, 1817, being five cents per ton. That act was intended to give effect on our side to an arrangement made with the Spanish Government by which discriminating duties of tonnage were to be abolished in the ports of the United States and Spain on he vessels of the two nations. Pursuant to that arrangement, which was carried into effect on the part of Spain on May 20th, 1832, by a royal order dated April 29th, 1832, American vessels in the ports of Spain have paid five cents per ton, which rate of duty is also paid in those ports by Spanish ships; but as American vessels pay no tonnage duty in the ports of the United States, the duty of five cents payable in our ports by Spanish vessels under the act above mentioned is really a discriminating duty, operating to the disadvantage of Spain. Though no complaint has yet been made on the part of Spain, we are not the less bound by the obligations of good faith to remove the discrimination, and I recommend that the act be amended accordingly. As the royal order above alluded to includes the ports of the Balearic and Canary islands as well as those of Spain, it would seem that the provisions of the act of Congress should be equally extensive, and that for the repayments of such duties as may have been improperly received an addition should be made to the sum appropriated at the last session of Congress for refunding discriminating duties.
