Was there ever a nation upon which the sun of heaven has shone which has exhibited so much of prosperity as our own? At the commencement of this government, our population amounted to about four millions. It has now reached upwards of twenty millions. Our territory was limited chiefly and principally to that bordering upon the Atlantic Ocean, and that which includes the southern shores of the interior lakes of our country. Our territory now extends from the northern provinces of Great Britain to the Rio Grande and the Gulf of Mexico; from the Atlantic Ocean on the one side to the Pacific on the other—the largest extent of territory under one government existing upon earth, with only two solitary exceptions. Our tonnage, from being nothing, has risen to a magnitude and amount to rival that of the nation which has been proudly called the mistress of the ocean.

We have gone through many wars; one with that very nation from whom in 1776 we broke off, as weak and feeble colonies, when we asserted our independence as a member of the family of nations. And, sir, we came out of that struggle—unequal as it was, armed as she was at all points in consequence of the long struggles of Europe, and unarmed as we were at all points, in consequence of the habits and nature of our country and its institutions—we came out of that war without the loss of any honor whatever; we emerged from it gloriously. In every Indian war—we have been engaged in many of them—our arms have been triumphant, and without speaking at all as to the causes of the recent war with Mexico, whether they were right or wrong, and abstaining from the expression of any opinion as to the justice or propriety of the war when it commenced, all must unite in respect to the gallantry of our arms and the glory of our triumphs.

There is no page—there are no pages of history which record more brilliant successes. With respect to the one in command of an important portion of our army, I need say nothing in praise of him who has been borne by the voice of his country to the highest station in it, mainly on account of his glorious military career. 2 But of another military commander, less fortunate in other respects, I must take the opportunity of saying that for skill, for science, for strategy, for bold and daring fighting, for chivalry of individuals and of masses, that portion of the Mexican War which was conducted by the gallant Scott, as chief commander, stands unrivaled either by the deeds of Cortes himself or by those of any other commander in ancient or modern times.

Our prosperity is unbounded. Nay, Mr. President, I sometimes fear that it is the very wantonness of our prosperity that leads us to these threatening ills of the moment—that restlessness and these erratic schemes throughout the whole country, some of which have even found their way into legislative halls. We want, I fear, the chastising wand of heaven to bring us back to a sense of the immeasurable benefits and blessings which have been bestowed upon us by providence. At this moment, with the exception of here and there a particular department in the manufacturing business of the country, all are prosperous and happy—both the rich and the poor. Our nation has grown to a magnitude in power and in greatness to command the respect, if it does not call for the apprehensions, of all the powers of the earth with which we can come into contact. Sir, do I depict with colors too lively the prosperity which has resulted to us from the operation of the Constitution under which we live? Have I exaggerated in any degree?

Such is the Union, and such are its glorious fruits. We are told now, and it is rung throughout this entire country, that the Union is threatened with subversion and destruction. Well, the first question which naturally arises is, supposing the Union to be dissolved—having all the causes of grievance which are complained of—how far will dissolution furnish a remedy for those grievances? If the Union is to be dissolved for any existing causes, it will be dissolved because slavery is interdicted or not allowed to be introduced into the ceded territories; because slavery is threatened to be abolished in the District of Columbia; and because fugitive slaves are not returned, as in my opinion they ought to be, and restored to their masters. These, I believe, will be the causes, if there be any causes, which can lead to the direful event to which I have referred.

Well, now, let us suppose that the Union has been dissolved. What remedy does it furnish for the grievances complained of in its united condition? Will you be able to push slavery into the ceded Territories? How are you to do it, supposing the North—all the States north of the Potomac, and which are opposed to it—in possession of the navy and army of the United States? Can you expect, if there is a dissolution of the Union, that you can carry slavery into California and New Mexico? You can not dream of such a purpose. If it were abolished in the District of Columbia, and the Union were dissolved, would the dissolution of the Union restore slavery in the District of Columbia? Are you safer in the recovery of your fugitive slaves, in a state of dissolution or of severance of the Union, than you are in the Union itself?

But, I must take occasion to say that, in my opinion, there is no right on the part of one or more of the States to secede from the Union. War and the dissolution of the Union are identical and inseparable. There can be no dissolution of the Union except by consent or by war. No one can expect, in the existing state of things, that that consent would be given, and war is the only alternative by which a dissolution could be accomplished. And, Mr. President, if consent were given—if possibly we were to separate by mutual agreement and by a given line, in less than sixty days after such an agreement had been executed, war would break out between the free and slave-holding portions of this Union—between the two independent portions into which it would be erected in virtue of the act of separation.

Yes, air, sixty days—in less than sixty days, I believe, our slaves from Kentucky would be fleeing over in numbers to the other side of the river, would be pursued by their owners, and the excitable and ardent spirits who would engage in the pursuit would be restrained by no sense of the rights which appertain to the independence of the other side of the river, supposing it, then, to be the line of separation. They would pursue their slaves; they would be repelled, and war would break out. In less than sixty days war would be blazing forth in every part of this now happy and peaceable land.

But how are you going to separate them? In my humble opinion, Mr. President, we should begin at least with three confederacies—the Confederacy of the North, the Confederacy of the Atlantic Southern States (the slave-holding States), and the Confederacy of the Valley of the Mississippi. My life upon it, sir, that vast population that has already concentrated, and will concentrate, upon the headquarters and tributaries of the Mississippi, will never consent that the mouth of that river shall be held subject to the power of any foreign State whatever. Such, I believe, would be the consequences of a dissolution of the Union. But other confederacies would spring up, from time to time, as dissatisfaction and discontent were disseminated over the country. There would be the Confederacy of the Lakes—perhaps the Confederacy of New England and of the Middle States.

I said that I thought that there was no right on the part of one or more of the States to secede from this Union. I think that the Constitution of the thirteen States was made, not merely for the generation which then existed, but for posterity, undefined, unlimited, permanent, and perpetual—for their posterity, and for every subsequent State which might come into the Union, binding themselves by that indissoluble bond. It is to remain for that posterity now and for ever. Like another of the great relations of private life, it was a marriage that no human authority can dissolve or divorce the parties from; and, if I may be allowed to refer to this same example in private life, let us say what man and wife say to each other: “We have mutual faults; nothing in the form of human beings can be perfect. Let us then be kind to each other, forbearing, conceding; let us live in happiness and peace.”

Mr. President, I have said what I solemnly believe—that the dissolution of the Union and war are identical and inseparable; that they are convertible terms.

Such a war, too, as that would be, following the dissolution of the Union! Sir, we may search the pages of history, and none so furious, so bloody, so implacable, so exterminating, from the wars of Greece down, including those of the Commonwealth of England, and the Revolution of France—none, none of them raged with such violence, or was ever conducted with such bloodshed and enormities, as will that war which shall follow that disastrous event—if that event ever happens—of dissolution.

And what would be its termination? Standing armies and navies, to an extent draining the revenues of each portion of the dissevered empire, would be created; exterminating wars would follow—not a war of two, nor three years, but of interminable duration—an exterminating war would follow, until some Philip or Alexander, some Cæsar or Napoleon, would rise to cut the Gordian knot, and solve the problem of the capacity of man for self-government, and crush the liberties of both the dissevered portions of this Union.

Can you doubt it? Look at history—consult the pages of all history, ancient or modern; look at human nature, look at the character of the contest in which you would be engaged in the supposition of a war following the dissolution of the Union, such as I have suggested—and I ask you if it is possible for you to doubt that the final but perhaps distant termination of the whole will be some despot treading down the liberties of the people?—that the final result will be the extinction of this last and glorious light, which is leading all mankind, who are gazing upon it, to cherish hope and anxious expectation that the liberty which prevails here will sooner or later be advanced throughout the civilized world?

Can you, Mr. President, lightly contemplate the consequences? Can you yield yourself to a torrent of passion, amid dangers which I have depicted in colors far short of what would be the reality, if the event should ever happen? I conjure gentlemen—whether from the South or the North—by all they hold dear in this world—by all their love of liberty—by all their veneration for their ancestors—by all their regard for posterity—by all their gratitude to Him who has bestowed upon them such unnumbered blessings—by all the duties which they owe to mankind, and all the duties they owe to themselves—by all these considerations I implore them to pause—solemnly to pause—at the edge of the precipice before the fearful and disastrous leap is taken in the yawning abyss below, which will inevitably lead to certain and irretrievable destruction.

And, finally, Mr. President, I implore, as the best blessing which heaven can bestow upon me on earth, that if the direful and sad event of the dissolution of the Union shall happen, I may not survive to behold the sad and heartrending spectacle.
