Whereas by an act of Congress of the United States of the 25th of May, 1832, entitled "An act to exempt the vessels of Portugal from the payment of duties of tonnage," it was enacted as follows: "No duties upon tonnage shall be hereafter levied or collected of the vessels of the Kingdom of Portugal: Provided, always, That whenever the President of the United States shall be satisfied that the vessels of the United States are subjected in the ports of the Kingdom of Portugal to payment of any duties of tonnage, he shall by proclamation declare the fact, and the duties now payable by vessels of that Kingdom shall be levied and paid as if this act had not been passed;" and

Whereas satisfactory evidence has been received by me not only that the vessels of the United States are subjected in the ports of the said Kingdom of Portugal to payment of duties of tonnage, but that a discrimination exists in respect to those duties against the vessels of the United States:

Now, therefore, I, Martin Van Buren, President of the United States of America, do hereby declare that fact and proclaim that the duties payable by vessels of the said Kingdom of Portugal on the 25th day of May, 1832, shall henceforth be levied and paid as if the said act of the 25th of May, 1832, had not been passed.

Given under my hand, at the city of Washington, the 11th day of October, 1837, and of the Independence of the United States the sixty-second.

M. VAN BUREN.

By the President:
JOHN FORSYTH,
Secretary of State.
