"The open manner in which disunion, secession, or a separation of the States, is suggested and recommended in some parts of the country, naturally calls on those to whom are confided the power and trust of maintaining the Constitution, and seeing that the laws of the United States be faithfully executed, to reflect upon the duties which events not yet indeed probable, but possible, may require them to perform. In the Northern and Eastern States, these sentiments of disunion are espoused principally by persons of heated imaginations, assembling together and passing resolutions of such wild and violent character as to render them nearly harmless. It is not so in other parts of the country. There are States in the South in which secession and dismemberment are proposed or recommended by persons of character and influence, filling stations of high public trust, and, it is painful to add, in some instances, not unconnected with the Government of the United States itself. Legislatures of some of the States have directed the government of those States to reassemble them in the contingency of the passage of certain laws by Congress. While these occurrences do not constitute an exigency calling for any positive proceeding either by the Executive Government of the United States or by Congress, yet they justly awaken attention, and admonish those in whose hands the administration of the government is placed, not to be found either unadvised, surprised, or unprepared, should a crisis arrive. The Constitution of the United States is founded on the idea of a division of power between the general government and the respective State governments; and this division is marked out and defined by the Constitution of the United States with as much distinctness and accuracy as the nature of the subject and the imperfection of language will admit. The powers of Congress are specifically enumerated, and all other powers necessary to carry these specified powers into effect are also expressly granted. The Constitution was adopted by the people in the several States, acting through the agency of conventions chosen by themselves; the Legislatures of the States had nothing to do with this proceeding, but to regulate the time and manner in which these conventions thus chosen by the people, the true source of all power, should assemble. The Constitution of the United States purports to be a perpetual form of government; it contains no limits for its duration, and suggests no means and no form of proceeding by which it can be dissolved, or its obligations dispensed with; it requires the personal allegiance of every citizen of the United States, and demands a solemn oath for its support from every man employed in any public trust, whether under the Government of the United States, or any State government. This obligation and this oath are enjoined in broad and general terms without qualification or modification, and with reference
