Whereas it appears by a proclamation of the lieutenant-governor of His Britannic Majesty's Province of New Brunswick bearing date the 10th day of April last, and officially communicated by his envoy extraordinary and minister plenipotentiary residing in the United States to this Government, that the regulations on the subject of the trade in plaster of paris, prohibiting the exportation thereof to certain ports of the United States, which were in force in the said Province at the time of the enactment of the act of the Congress of the United States entitled "An act to regulate the trade in plaster of paris," passed on the 3d day of March, 1817, have been and are discontinued: Now, therefore, I, James Monroe, President of the United States, do hereby declare that fact, and that the restrictions imposed by the said act of Congress shall from the date hereof cease and be discontinued in relation to the said Province of New Brunswick. Given under my hand, at the city of Washington, this 4th day of July, A.D. 1818, and in the forty-third year of the Independence of the United States. JAMES MONROE. By the President: John Quincy Adams, _Secretary of State_. BY THE PRESIDENT OF THE UNITED STATES OF AMERICA. A PROCLAMATION. Whereas by an act of the Congress of the United States of the 3d of March, 1815, so much of the several acts imposing duties on the ships and vessels and on goods, wares, and merchandise imported into the United States as imposed a discriminating duty of tonnage between foreign vessels and vessels of the United States and between goods imported into the United States in foreign vessels and vessels of the United States were repealed so far as the same respected the produce or manufacture of the nation to which such foreign ship or vessel might belong, such repeal to take effect in favor of any foreign nation whenever the President of the United States should be satisfied that the discriminating or countervailing duties of such foreign nation so far as they operate to the disadvantage of the United States have been abolished; and Whereas satisfactory proof has been received by me from the burgo-masters and senators of the free and Hanseatic city of Bremen that from and after the 12th day of May, 1815, all discriminating or countervailing duties of the said city so far as they operated to the disadvantage of the United States have been and are abolished:
