The Union of the United States of America was intended by its authors to last as long as the States themselves shall last. "The Union shall be perpetual" are the words of the Confederation. "To form a more perfect Union," by an ordinance of the people of the United States, is the declared purpose of the Constitution. The hand of Divine Providence was never more plainly visible in the affairs of men than in the framing and the adopting of that instrument. It is beyond comparison the greatest event in American history, and, indeed, is it not of all events in modern times the most pregnant with consequences for every people of the earth? The members of the Convention which prepared it brought to their work the experience of the Confederation, of their several States, and of other republican governments, old and new; but they needed and they obtained a wisdom superior to experience. And when for its validity it required the approval of a people that occupied a large part of a continent and acted separately in many distinct conventions, what is more wonderful than that, after earnest contention and long discussion, all feelings and all opinions were ultimately drawn in one way to its support? The Constitution to which life was thus imparted contains within itself ample resources for its own preservation. It has power to enforce the laws, punish treason, and insure domestic tranquillity. In case of the usurpation of the government of a State by one man or an oligarchy, it becomes a duty of the United States to make good the guaranty to that State of a republican form of government, and so to maintain the homogeneousness of all. Does the lapse of time reveal defects? A simple mode of amendment is provided in the Constitution itself, so that its conditions can always be made to conform to the requirements of advancing civilization. No room is allowed even for the thought of a possibility of its coming to an end. And these powers of self-preservation have always been asserted in their complete integrity by every patriotic Chief Magistrate by Jefferson and Jackson not less than by Washington and Madison. The parting advice of the Father of his Country, while yet President, to the people of the United States was that the free Constitution, which was the work of their hands, might be sacredly maintained; and the inaugural words of President Jefferson held up "the preservation of the General Government in its whole constitutional vigor as the sheet anchor of our peace at home and safety abroad." The Constitution is the work of "the people of the United States," and it should be as indestructible as the people.
