Hence, while the General Government, as well by the enumerated powers granted to it as by those not enumerated, and therefore refused to it, was forbidden to touch this matter in the sense of attack or offense, it was placed under the general safeguard of the Union in the sense of defense against either invasion or domestic violence, like all other local interests of the several States. Each State expressly stipulated, as well for itself as for each and all of its citizens, and every citizen of each State became solemnly bound by his allegiance to the Constitution that any person held to service or labor in one State, escaping into another, should not, in consequence of any law or regulation thereof, be discharged from such service or labor, but should be delivered up on claim of the party to whom such service or labor might be due by the laws of his State.

Thus and thus only, by the reciprocal guaranty of all the rights of every State against interference on the part of another, was the present form of government established by our fathers and transmitted to us, and by no other means is it possible for it to exist. If one State ceases to respect the rights of another and obtrusively intermeddles with its local interests; if a portion of the States assume to impose their institutions on the others or refuse to fulfill their obligations to them, we are no longer united, friendly States, but distracted, hostile ones, with little capacity left of common advantage, but abundant means of reciprocal injury and mischief. Practically it is immaterial whether aggressive interference between the States or deliberate refusal on the part of any one of them to comply with constitutional obligations arise from erroneous conviction or blind prejudice, whether it be perpetrated by direction or indirection. In either case it is full of threat and of danger to the durability of the Union.

Placed in the office of Chief Magistrate as the executive agent of the whole country, bound to take care that the laws be faithfully executed, and specially enjoined by the Constitution to give information to Congress on the state of the Union, it would be palpable neglect of duty on my part to pass over a subject like this, which beyond all things at the present time vitally concerns individual and public security.

It has been matter of painful regret to see States conspicuous for their services in founding this Republic and equally sharing its advantages disregard their constitutional obligations to it. Although conscious of their inability to heal admitted and palpable social evils of their own, and which are completely within their jurisdiction, they engage in the offensive and hopeless undertaking of reforming the domestic institutions of other States, wholly beyond their control and authority. In the vain pursuit of ends by them entirely unattainable, and which they may not legally attempt to compass, they peril the very existence of the Constitution and all the countless benefits which it has conferred. While the people of the Southern States confine their attention to their own affairs, not presuming officiously to intermeddle with the social institutions of the Northern States, too many of the inhabitants of the latter are permanently organized in associations to inflict injury on the former by wrongful acts, which would be cause of war as between foreign powers and only fail to be such in our system because perpetrated under cover of the Union.

Is it possible to present this subject as truth and the occasion require without noticing the reiterated but groundless allegation that the South has persistently asserted claims and obtained advantages in the practical administration of the General Government to the prejudice of the North, and in which the latter has acquiesced? That is, the States which either promote or tolerate attacks on the rights of persons and of property in other States, to disguise their own injustice, pretend or imagine, and constantly aver, that they, whose constitutional rights are thus systematically assailed, are themselves the aggressors. At the present time this imputed aggression, resting, as it does, only in the vague declamatory charges of political agitators, resolves itself into misapprehension, or misinterpretation, of the principles and facts of the political organization of the new Territories of the United States.

What is the voice of history? When the ordinance which provided for the government of the territory northwest of the river Ohio and for its eventual subdivision into new States was adopted in the Congress of the Confederation, it is not to be supposed that the question of future relative power as between the States which retained and those which did not retain a numerous colored population escaped notice or failed to be considered. And yet the concession of that vast territory to the interests and opinions of the Northern States, a territory now the seat of five among the largest members of the Union, was in great measure the act of the State of Virginia and of the South.

When Louisiana was acquired by the United States, it was an acquisition not less to the North than to the South; for while it was important to the country at the mouth of the river Mississippi to become the emporium of the country above it, so also it was even more important to the whole Union to have that emporium; and although the new province, by reason of its imperfect settlement, was mainly regarded as on the Gulf of Mexico, yet in fact it extended to the opposite boundaries of the United States, with far greater breadth above than below, and was in territory, as in everything else, equally at least an accession to the Northern States. It is mere delusion and prejudice, therefore, to speak of Louisiana as acquisition in the special interest of the South.

The patriotic and just men who participated in that act were influenced by motives far above all sectional jealousies. It was in truth the great event which, by completing for us the possession of the Valley of the Mississippi, with commercial access to the Gulf of Mexico, imparted unity and strength to the whole Confederation and attached together by indissoluble ties the East and the West, as well as the North and the South.

As to Florida, that was but the transfer by Spain to the United States of territory on the east side of the river Mississippi in exchange for large territory which the United States transferred to Spain on the west side of that river, as the entire diplomatic history of the transaction serves to demonstrate. Moreover, it was an acquisition demanded by the commercial interests and the security of the whole Union.

In the meantime the people of the United States had grown up to a proper consciousness of their strength, and in a brief contest with France and in a second serious war with Great Britain they had shaken off all which remained of undue reverence for Europe, and emerged from the atmosphere of those transatlantic influences which surrounded the infant Republic, and had begun to turn their attention to the full and systematic development of the internal resources of the Union.
