Our differences with Spain remain still unsettled, no measure having been taken on her part since my last communications to Congress to bring them to a close. But under a state of things which may favor reconsideration they have been recently pressed, and an expectation is entertained that they may now soon be brought to an issue of some sort. With their subjects on our borders no new collisions have taken place nor seem immediately to be apprehended. To our former grounds of complaint has been added a very serious one, as you will see by the decree a copy of which is now communicated. Whether this decree, which professes to be conformable to that of the French Government of November 21, 1806, heretofore communicated to Congress, will also be conformed to that in its construction and application in relation to the United States had not been ascertained at the date of our last communications. These, however, gave reason to expect such a conformity.

With the other nations of Europe our harmony has been uninterrupted, and commerce and friendly intercourse have been maintained on their usual footing.

Our peace with the several states on the coast of Barbary appears as firm as at any former period and as likely to continue as that of any other nation.

Among our Indian neighbors in the northwestern quarter some fermentation was observed soon after the late occurrences, threatening the continuance of our peace. Messages were said to be interchanged and tokens to be passing, which usually denote a state of restlessness among them, and the character of the agitators pointed to the sources of excitement. Measures were immediately taken for providing against that danger; instructions were given to require explanations, and, with assurances of our continued friendship, to admonish the tribes to remain quiet at home, taking no part in quarrels not belonging to them. As far as we are yet informed, the tribes in our vicinity, who are most advanced in the pursuits of industry, are sincerely disposed to adhere to their friendship with us and to their peace with all others, while those more remote do not present appearances sufficiently quiet to justify the intermission of military precaution on our part.

The great tribes on our southwestern quarter, much advanced beyond the others in agriculture and household arts, appear tranquil and identifying their views with ours in proportion to their advancement. With the whole of these people, in every quarter, I shall continue to inculcate peace and friendship with all their neighbors and perseverance in those occupations and pursuits which will best promote their own well-being.

The appropriations of the last session for the defense of our seaport towns and harbors were made under expectation that a continuance of our peace would permit us to proceed in that work according to our convenience. It has been thought better to apply the sums then given toward the defense of New York, Charleston, and New Orleans chiefly, as most open and most likely first to need protection, and to leave places less immediately in danger to the provisions of the present session.

The gunboats, too, already provided have on a like principle been chiefly assigned to New York, New Orleans, and the Chesapeake. Whether our movable force on the water, so material in aid of the defensive works on the land, should be augmented in this or any other form is left to the wisdom of the Legislature. For the purpose of manning these vessels in sudden attacks on our harbors it is a matter for consideration whether the seamen of the United States may not justly be formed into a special militia, to be called on for tours of duty in defense of the harbors where they shall happen to be, the ordinary militia of the place furnishing that portion which may consist of landsmen.

The moment our peace was threatened I deemed it indispensable to secure a greater provision of those articles of military stores with which our magazines were not sufficiently furnished. To have awaited a previous and special sanction by law would have lost occasions which might not be retrieved. I did not hesitate, therefore, to authorize engagements for such supplements to our existing stock as would render it adequate to the emergencies threatening us, and I trust that the Legislature, feeling the same anxiety for the safety of our country, so materially advanced by this precaution, will approve, when done, what they would have seen so important to be done if then assembled. Expenses, also unprovided for, arose out of the necessity of calling all our gunboats into actual service for the defense of our harbors; of all which accounts will be laid before you.

Whether a regular army is to be raised, and to what extent, must depend on the information so shortly expected. In the meantime I have called on the States for quotas of militia, to be in readiness for present defense, and have, moreover, encouraged the acceptance of volunteers; and I am happy to inform you that these have offered themselves with great alacrity in every part of the Union. They are ordered to be organized and ready at a moment's warning to proceed on any service to which they may be called, and every preparation within the Executive powers has been made to insure us the benefit of early exertions.

I informed Congress at their last session of the enterprises against the public peace which were believed to be in preparation by Aaron Burr and his associates, of the measures taken to defeat them and to bring the offenders to justice. Their enterprises were happily defeated by the patriotic exertions of the militia whenever called into action, by the fidelity of the Army, and energy of the commander in chief in promptly arranging the difficulties presenting themselves on the Sabine, repairing to meet those arising on the Mississippi, and dissipating before their explosion plots engendering there. I shall think it my duty to lay before you the proceedings and the evidence publicly exhibited on the arraignment of the principal offenders before the circuit court of Virginia. You will be enabled to judge whether the defect was in the testimony, in the law, or in the administration of the law; and wherever it shall be found, the Legislature alone can apply or originate the remedy. The framers of our Constitution certainly supposed they had guarded as well their Government against destruction by treason as their citizens against oppression under pretense of it, and if these ends are not attained it is of importance to inquire by what means more effectual they may be secured.
