Whereas by an act of the Congress of the United States of the 24th of May, 1828, entitled "An act in addition to an act entitled 'An act concerning discriminating duties of tonnage and impost' and to equalize the duties on Prussian vessels and their cargoes," it is provided that, upon satisfactory evidence being given to the President of the United States by the government of any foreign nation that no discriminating duties of tonnage or impost are imposed or levied in the ports of the said nation upon vessels wholly belonging to citizens of the United States or upon the produce, manufactures, or merchandise imported in the same from the United States or from any foreign country, the President is thereby authorized to issue his proclamation declaring that the foreign discriminating duties of tonnage and impost within the United States are and shall be suspended and discontinued so far as respects the vessels of the said foreign nation and the produce, manufactures, or merchandise imported into the United States in the same from the said foreign nation or from any other foreign country, the said suspension to take effect from the time of such notification being given to the President of the United States and to continue so long as the reciprocal exemption of vessels belonging to citizens of the United States and their cargoes, as aforesaid, shall be continued, and no longer; and Whereas satisfactory evidence has lately been received by me from His Majesty the King of the Hawaiian Islands, through an official communication of His Majesty's minister of foreign relations under date of the 10th of December, 1866, that no other or higher duties of tonnage and impost are imposed or levied in the ports of the Hawaiian Islands upon vessels wholly belonging to citizens of the United States and upon the produce, manufactures, or merchandise imported in the same from the United States and from any foreign country whatever than are levied on Hawaiian ships and their cargoes in the same ports under like circumstances: Now, therefore, I, Andrew Johnson, President of the United States of America, do hereby declare and proclaim that so much of the several acts imposing discriminating duties of tonnage and impost within the United States are and shall be suspended and discontinued so far as respects the vessels of the Hawaiian Islands and the produce, manufactures, and merchandise imported into the United States in the same from the dominions of the Hawaiian Islands and from any other foreign country whatever, the said suspension to take effect from the said 10th day of December and to continue thenceforward so long as the reciprocal exemption of the vessels of the United States and the produce, manufactures, and merchandise imported into the dominions of the Hawaiian Islands in the same, as aforesaid, shall be continued on the part of the Government of His Majesty the King of the Hawaiian Islands.
