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 wherever 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 defeat 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 pretence of it; and if these ends are not attained, it is of importance to inquire by what means, more effectual, they may be secured.

The accounts of the receipts of revenue, during the year ending on the thirtieth day of September last, being not yet made up, a correct statement will be hereafter transmitted from the treasury. In the meantime, it is ascertained that the receipts have amounted to near sixteen millions of dollars, which, with the five millions and a half in the treasury at the beginning of the year, have enabled us, after meeting the current demands and interest incurred, to pay more than four millions of the principal of our funded debt. These payments, with those of the preceding five and a half years, have extinguished of the funded debt twenty-five millions and a half of dollars, being the whole which could be paid or purchased within the limits of the law and of our contracts, and have left us in the treasury eight millions and a half of dollars. A portion of this sum may be considered as a commencement of accumulation of the surpluses of revenue, which, after paying the instalments of debts as they shall become payable, will remain without any specific object. It may partly, indeed, be applied toward completing the defence of the exposed points of our country, on such a scale as shall be adapted to our principles and circumstances. This object is doubtless among the first entitled to attention, in such a state of our finances, and it is one which, whether we have peace or war, will provide security where it is due. Whether what shall remain of this, with the future surpluses, may be usefully applied to purposes already authorized, or more usefully to others requiring new authorities, or how otherwise they shall be disposed of, are questions calling for the notice of Congress, unless indeed they shall be superseded by a change in our public relations now awaiting the determination of others. Whatever be that determination, it is a great consolation that it will become known at a moment when the supreme council of the nation is assembled at its post, and ready to give the aids of its wisdom and authority to whatever course the good of our country shall then call us to pursue.

Matters of minor importance will be the subjects of future communications; and nothing shall be wanting on my part which may give information or despatch to the proceedings of the legislature in the exercise of their high duties, and at a moment so interesting to the public welfare.

SPECIAL MESSAGE.—November 23, 1807.

To the Senate and House of Representatives of the United States:—

Agreeably to the assurance in my message at the opening of the present session of Congress, I now lay before you a copy of the proceedings, and of the evidence exhibited on the arraignment of Aaron Burr, and others, before the circuit court of the United States, held in Virginia, in the course of the present year, in as authentic form as their several parts have admitted.

SPECIAL MESSAGE.—December 18, 1807.

To the Senate and House of Representatives of the United States:—

The communications now made, showing the great and increasing dangers with which our vessels, our seamen, and merchandise, are threatened on the high seas and elsewhere, from the belligerent powers of Europe, and it being of great importance to keep in safety these essential resources, I deem it my duty to recommend the subject to the consideration of Congress, who will doubtless perceive all the advantages which may be expected from an inhibition of the departure of our vessels from the ports of the United States.

Their wisdom will also see the necessity of making every preparation for whatever events may grow out of the present crisis.
