The colony of Newfoundland, having enacted the laws required by the treaty of the 5th of June, 1854, is now placed on the same footing in respect to commercial intercourse with the United States as the other British North American Provinces. The commission which that treaty contemplated, for determining the rights of fishery in rivers and mouths of rivers on the coasts of the United States and the British North American Provinces, has been organized, and has commenced its labors, to complete which there are needed further appropriations for the service of another season. In pursuance of the authority conferred by a resolution of the Senate of the United States passed on the 3d of March last, notice was given to Denmark on the 14th day of April of the intention of this Government to avail itself of the stipulation of the subsisting convention of friendship, commerce, and navigation between that Kingdom and the United States whereby either party might after ten years terminate the same at the expiration of one year from the date of notice for that purpose. The considerations which led me to call the attention of Congress to that convention and induced the Senate to adopt the resolution referred to still continue in full force. The convention contains an article which, although it does not directly engage the United States to submit to the imposition of tolls on the vessels and cargoes of Americans passing into or from the Baltic Sea during the continuance of the treaty, yet may by possibility be construed as implying such submission. The exaction of those tolls not being justified by any principle of international law, it became the right and duty of the United States to relieve themselves from the implication of engagement on the subject, so as to be perfectly free to act in the premises in such way as their public interests and honor shall demand. I remain of the opinion that the United States ought not to submit to the payment of the Sound dues, not so much because of their amount, which is a secondary matter, but because it is in effect the recognition of the right of Denmark to treat one of the great maritime highways of nations as a close sea, and prevent the navigation of it as a privilege, for which tribute may be imposed upon those who have occasion to use it. This Government on a former occasion, not unlike the present, signalized its determination to maintain the freedom of the seas and of the great natural channels of navigation. The Barbary States had for a long time coerced the payment of tribute from all nations whose ships frequented the Mediterranean. To the last demand of such payment made by them the United States, although suffering less by their depredations than many other nations, returned the explicit answer that we preferred war to tribute, and thus opened the way to the relief of the commerce of the world from an ignominious tax, so long submitted to by the more powerful nations of Europe.
