Whilst it is the duty of the President "from time to time to give to Congress information of the state of the Union," I shall not refer in detail to the recent sad and bloody occurrences at Harpers Ferry. Still, it is proper to observe that these events, however bad and cruel in themselves, derive their chief importance from the apprehension that they are but symptoms of an incurable disease in the public mind, which may break out in still more dangerous outrages and terminate at last in an open war by the North to abolish slavery in the South.

Whilst for myself I entertain no such apprehension, they ought to afford a solemn warning to us all to beware of the approach of danger. Our Union is a stake of such inestimable value as to demand our constant and watchful vigilance for its preservation. In this view, let me implore my countrymen, North and South, to cultivate the ancient feelings of mutual forbearance and good will toward each other and strive to allay the demon spirit of sectional hatred and strife now alive in the land. This advice proceeds from the heart of an old public functionary whose service commenced in the last generation, among the wise and conservative statesmen of that day, now nearly all passed away, and whose first and dearest earthly wish is to leave his country tranquil, prosperous, united, and powerful.

We ought to reflect that in this age, and especially in this country, there is an incessant flux and reflux of public opinion. Questions which in their day assumed a most threatening aspect have now nearly gone from the memory of men. They are "volcanoes burnt out, and on the lava and ashes and squalid scoria of old eruptions grow the peaceful olive, the cheering vine, and the sustaining corn." Such, in my opinion, will prove to be the fate of the present sectional excitement should those who wisely seek to apply the remedy continue always to confine their efforts within the pale of the Constitution. If this course be pursued, the existing agitation on the subject of domestic slavery, like everything human, will have its day and give place to other and less threatening controversies. Public opinion in this country is all-powerful, and when it reaches a dangerous excess upon any question the good sense of the people will furnish the corrective and bring it back within safe limits. Still, to hasten this auspicious result at the present crisis we ought to remember that every rational creature must be presumed to intend the natural consequences of his own teachings. Those who announce abstract doctrines subversive of the Constitution and the Union must not be surprised should their heated partisans advance one step further and attempt by violence to carry these doctrines into practical effect. In this view of the subject, it ought never to be forgotten that however great may have been the political advantages resulting from the Union to every portion of our common country, these would all prove to be as nothing should the time ever arrive when they can not be enjoyed without serious danger to the personal safety of the people of fifteen members of the Confederacy. If the peace of the domestic fireside throughout these States should ever be invaded, if the mothers of families within this extensive region should not be able to retire to rest at night without suffering dreadful apprehensions of what may be their own fate and that of their children before the morning, it would be vain to recount to such a people the political benefits which result to them from the Union. Self-preservation is the first instinct of nature, and therefore any state of society in which the sword is all the time suspended over the heads of the people must at last become intolerable. But I indulge in no such gloomy forebodings. On the contrary, I firmly believe that the events at Harpers Ferry, by causing the people to pause and reflect upon the possible peril to their cherished institutions, will be the means under Providence of allaying the existing excitement and preventing further outbreaks of a similar character. They will resolve that the Constitution and the Union shall not be endangered by rash counsels, knowing that should "the silver cord be loosed or the golden bowl be broken ... at the fountain" human power could never reunite the scattered and hostile fragments.

I cordially congratulate you upon the final settlement by the Supreme Court of the United States of the question of slavery in the Territories, which had presented an aspect so truly formidable at the commencement of my Administration. The right has been established of every citizen to take his property of any kind, including slaves, into the common Territories belonging equally to all the States of the Confederacy, and to have it protected there under the Federal Constitution. Neither Congress nor a Territorial legislature nor any human power has any authority to annul or impair this vested right. The supreme judicial tribunal of the country, which is a coordinate branch of the Government, has sanctioned and affirmed these principles of constitutional law, so manifestly just in themselves and so well calculated to promote peace and harmony among the States. It is a striking proof of the sense of justice which is inherent in our people that the property in slaves has never been disturbed, to my knowledge, in any of the Territories. Even throughout the late troubles in Kansas there has not been any attempt, as I am credibly informed, to interfere in a single instance with the right of the master. Had any such attempt been made, the judiciary would doubtless have afforded an adequate remedy. Should they fail to do this hereafter, it will then be time enough to strengthen their hands by further legislation. Had it been decided that either Congress or the Territorial legislature possess the power to annul or impair the right to property in slaves, the evil would be intolerable. In the latter event there would be a struggle for a majority of the members of the legislature at each successive election, and the sacred rights of property held under the Federal Constitution would depend for the time being on the result. The agitation would thus be rendered incessant whilst the Territorial condition remained, and its baneful influence would keep alive a dangerous excitement among the people of the several States.

Thus has the status of a Territory during the intermediate period from its first settlement until it shall become a State been irrevocably fixed by the final decision of the Supreme Court. Fortunate has this been for the prosperity of the Territories, as well as the tranquillity of the States. Now emigrants from the North and the South, the East and the West, will meet in the Territories on a common platform, having brought with them that species of property best adapted, in their own opinion, to promote their welfare. From natural causes the slavery question will in each case soon virtually settle itself, and before the Territory is prepared for admission as a State into the Union this decision, one way or the other, will have been a foregone conclusion. Meanwhile the settlement of the new Territory will proceed without serious interruption, and its progress and prosperity will not be endangered or retarded by violent political struggles.

When in the progress of events the inhabitants of any Territory shall have reached the number required to form a State, they will then proceed in a regular manner and in the exercise of the rights of popular sovereignty to form a constitution preparatory to admission into the Union. After this has been done, to employ the language of the Kansas and Nebraska act, they "shall be received into the Union with or without slavery, as their constitution may prescribe at the time of their admission." This sound principle has happily been recognized in some form or other by an almost unanimous vote of both Houses of the last Congress.

All lawful means at my command have been employed, and shall continue to be employed, to execute the laws against the African slave trade. After a most careful and rigorous examination of our coasts and a thorough investigation of the subject, we have not been able to discover that any slaves have been imported into the United States except the cargo by the Wanderer, numbering between three and four hundred. Those engaged in this unlawful enterprise have been rigorously prosecuted, but not with as much success as their crimes have deserved. A number of them are still under prosecution.

Our history proves that the fathers of the Republic, in advance of all other nations, condemned the African slave trade. It was, notwithstanding, deemed expedient by the framers of the Constitution to deprive Congress of the power to prohibit "the migration or importation of such persons as any of the States now existing shall think proper to admit" "prior to the year 1808." It will be seen that this restriction on the power of Congress was confined to such States only as might think proper to admit the importation of slaves. It did not extend to other States or to the trade carried on abroad. Accordingly, we find that so early as the 22d March, 1794, Congress passed an act imposing severe penalties and punishments upon citizens and residents of the United States who should engage in this trade between foreign nations. The provisions of this act were extended and enforced by the act of 10th May, 1800.

Again, the States themselves had a clear right to waive the constitutional privilege intended for their benefit, and to prohibit by their own laws this trade at any time they thought proper previous to 1808. Several of them exercised this right before that period, and among them some containing the greatest number of slaves. This gave to Congress the immediate power to act in regard to all such States, because they themselves had removed the constitutional barrier. Congress accordingly passed an act on 28th February, 1803, "to prevent the importation of certain persons into certain States where by the laws thereof their admission is prohibited." In this manner the importation of African slaves into the United States was to a great extent prohibited some years in advance of 1808.

As the year 1808 approached Congress determined not to suffer this trade to exist even for a single day after they had the power to abolish it. On the 2d of March, 1807, they passed an act, to take effect "from and after the 1st day of January, 1808," prohibiting the importation of African slaves into the United States. This was followed by subsequent acts of a similar character, to which I need not specially refer. Such were the principles and such the practice of our ancestors more than fifty years ago in regard to the African slave trade. It did not occur to the revered patriots who had been delegates to the Convention, and afterwards became members of Congress, that in passing these laws they had violated the Constitution which they had framed with so much care and deliberation. They supposed that to prohibit Congress in express terms from exercising a specified power before an appointed day necessarily involved the right to exercise this power after that day had arrived.
