As soon as the war in Europe had embraced those powers with whom the United States have the most extensive relations there was reason to apprehend that our intercourse with them might be interrupted and our disposition for peace drawn into question by the suspicions too often entertained by belligerent nations.  It seemed, therefore, to be my duty to admonish our citizens of the consequences of a contraband trade and of hostile acts to any of the parties, and to obtain by a declaration of the existing legal state of things an easier admission of our right to the immunities belonging to our situation.  Under these impressions the proclamation which will be laid before you was issued.

In this posture of affairs, both new and delicate, I resolved to adopt general rules which should conform to the treaties and assert the privileges of the United States.  These were reduced into a system, which will be communicated to you.  Although I have not thought myself at liberty to forbid the sale of the prizes permitted by our treaty of commerce with France to be brought into our ports, I have not refused to cause them to be restored when they were taken within the protection of our territory, or by vessels commissioned or equipped in a warlike form within the limits of the United States.

It rests with the wisdom of Congress to correct, improve, or enforce this plan of procedure; and it will probably be found expedient to extend the legal code and the jurisdiction of the courts of the United States to many cases which, though dependent on principles already recognized, demand some further provisions.

Where individuals shall, within the United States, array themselves in hostility against any of the powers at war, or enter upon military expeditions or enterprises within the jurisdiction of the United States, or usurp and exercise judicial authority within the United States, or where the penalties on violations of the law of nations may have been indistinctly marked, or are inadequate—­these offenses can not receive too early and close an attention, and require prompt and decisive remedies.

Whatsoever those remedies may be, they will be well administered by the judiciary, who possess a long-established course of investigation, effectual process, and officers in the habit of executing it.

In like manner, as several of the courts have doubted, under particular circumstances, their power to liberate the vessels of a nation at peace, and even of a citizen of the United States, although seized under a false color of being hostile property, and have denied their power to liberate certain captures within the protection of our territory, it would seem proper to regulate their jurisdiction in these points.  But if the Executive is to be the resort in either of the two last-mentioned cases, it is hoped that he will be authorized by law to have facts ascertained by the courts when for his own information he shall request it.
