The commerce of the United States with the north of Europe, heretofore much vexed by licentious cruisers, particularly under the Danish flag, has latterly been visited with fresh and extensive depredations. The measures pursued in behalf of our injured citizens not having obtained justice for them, a further and more formal interposition with the Danish Government is contemplated. The principles which have been maintained by that Government in relation to neutral commerce, and the friendly professions of His Danish Majesty toward the United States, are valuable pledges in favor of a successful issue. Among the events growing out of the state of the Spanish Monarchy, our attention was imperiously attracted to the change developing itself in that portion of West Florida which, though of right appertaining to the United States, had remained in the possession of Spain awaiting the result of negotiations for its actual delivery to them. The Spanish authority was subverted and a situation produced exposing the country to ulterior events which might essentially affect the rights and welfare of the Union. In such a conjuncture I did not delay the interposition required for the occupancy of the territory west of the river Perdido, to which the title of the United States extends, and to which the laws provided for the Territory of Orleans are applicable. With this view, the proclamation of which a copy is laid before you was confided to the governor of that Territory to be carried into effect. The legality and necessity of the course pursued assure me of the favorable light in which it will present itself to the Legislature, and of the promptitude with which they will supply whatever provisions may be due to the essential rights and equitable interests of the people thus brought into the bosom of the American family. Our amity with the powers of Barbary, with the exception of a recent occurrence at Tunis, of which an explanation is just received, appears to have been uninterrupted and to have become more firmly established. With the Indian tribes also the peace and friendship of the United States are found to be so eligible that the general disposition to preserve both continues to gain strength.
