And what does all this demonstrate? That the sin of this nation is not geographical—is not specially Southern—but deep-seated and universal. "The whole head is sick, and the whole heart faint." We are "full of wounds, and bruises, and putrifying sores." It proves, too, the folly of all plasters and palliatives. Some men are still talking of preventing the spread of the cancer, but leaving it just where it is. They admit that, constitutionally, it has now a right to ravage two-thirds of the body politic—but they protest against its extension. This in moral quackery. Even some, whose zeal in the Anti-Slavery cause is fervent, are so infatuated as to propose no other remedy for Slavery but its non-extension. Give it no more room, they say, and it may be safely left to its fate. Yes, but who shall "bell the cat?" Besides, with fifteen Slave States, and more than three millions of Slaves, how can we make any moral issue with the Slave Power against its further extension? Why should there not be twenty, thirty, fifty Slave States, as well as fifteen? Why should not the star-spangled banner wave over ten, as well as over three millions of Slaves? Why should not Nebraska be cultivated by Slave labour, as well as Florida or Texas? If men, under the American Constitution, may hold slaves at discretion and without dishonour in one-half of the country, why not in the whole of it? If it would be a damning sin for us to admit another Slave State into the Union, why is it not a damning sin to permit a Slave State to remain in the Union? Would it not be the acme of effrontery for a man, in amicable alliance with fifteen pickpockets, to profess scruples of conscience in regard to admitting another pilfering rogue to the fraternity? "Thou that sayest, A man should not steal, dost thou steal," or consent, in any instance, to stealing? "If the Lord be God, serve Him; but if Baal, then serve him." The South may well laugh to scorn the affected moral sensibility of the North against the extension of her slave system. It is nothing, in the present relations of the States, but sentimental hypocrisy. It has no stamina—no back-bone. The argument for non-extension is an argument for the dissolution of the Union. With a glow of moral indignation, I protest against the promise and the pledge, by whomsoever made, that if the Slave Power will seek no more to lengthen its cords and strengthen its stakes, it may go unmolested end unchallenged, and survive as long as it can within its present limits. I would as soon turn pirate on the high seas as to give my consent to any such arrangement. I do not understand the moral code of those who, screaming in agony at the thought of Nebraska becoming a Slave Territory, virtually say to the South: "Only desist from your present designs, and we will leave you to flog, and lacerate, and plunder, and destroy the millions of hapless wretches already within your grasp. If you will no longer agitate the subject, we will not." There is no sense, no principle, no force in such an issue. Not a solitary slaveholder will I allow to enjoy repose on any other condition than instantly ceasing to be one. Not a single slave will I leave in his chains, on any conditions, or under any circumstances. I will not try to make as good a bargain for the Lord as the Devil will let me, and plead the necessity of a compromise, and regret that I cannot do any better, and be thankful that I can do so much. The Scriptural injunction is to be obeyed: "Resist the devil, and he will flee from you." My motto is, "No union with slaveholders, religiously or politically." Their motto is "Slavery forever! No alliance with Abolitionists, either in Church or State!" The issue is clear, explicit, determinate. The parties understand each other, and are drawn in battle array. They can never be reconciled—never walk together—never consent to a truce—never deal in honeyed phrases—never worship at the same altar—never acknowledge the same God. Between them there is an impassable gulf. In manners, in morals, in philosophy, in religion, in ideas of justice, in notions of law, in theories of government, in valuations or men, they are totally dissimilar.

I would to God that we might be, what we have never been—a united people; but God renders this possible only by "proclaiming liberty throughout all the land, unto all the inhabitants thereof." By what miracle can Freedom and Slavery be made amicably to strike hands? How can they administer the same Government, or legislate for the same interests? How can they receive the same baptism, be admitted to the same communion-table, believe in the same Gospel, and obtain the same heavenly inheritance? "I speak as unto wise men; judge ye." Certain propositions have long since been ceded to be plain, beyond contradiction. The apostolic inquiry has been regarded as equally admonitory and pertinent: "What concord hath Christ with Belial? or what fellowship hath light with darkness?" Fire and gunpowder, oil and water, cannot coalesce; but, assuredly, these are not more antagonistical than are the elements of Freedom and Slavery. The present American Union, therefore, is only one in form, not in reality. It is, and it always has been, the absolute supremacy of the Slave Power over the whole country—nothing more. What sectional heart-burnings or conflictive interests exist between the several Free States? None. They are homogeneous, animated by the same spirit, harmonious in their action as the movement of the spheres. It is only when we come to the dividing line between the Free States and the Slave States that shoals, breakers and whirlpools beset the ship of State, and threaten to engulf or strand it. Then the storm rages loud and long, and the ocean of popular feeling is lashed into fury.

While the present Union exists, I pronounce it hopeless to expect any repose, or that any barrier can be effectually raised against the extension of Slavery. With two thousand million dollars' worth of property in human flesh in its hands, to be watched and wielded as one vast interest for all the South—with forces never divided, and purposes never conflictive—with a spurious, negro-hating religion universally diffused, and everywhere ready to shield it from harm—with a selfish, sordid, divided North, long since bereft of its manhood, to cajole, bribe and intimidate—with its foot planted on two-thirds of our vast national domains, and there unquestioned, absolute and bloody in its sway—with the terrible strength and boundless resources of the whole country at its command—it cannot be otherwise than that the Slave Power will consummate its diabolical purposes to the uttermost. The Northwest Territory, Nebraska, Mexico, Cuba, Hayti, the Sandwich Islands, and colonial possessions in the tropics—to seize and subjugate these to its accursed reign, and ultimately to re-establish the foreign Slave Trade as a lawful commerce, are among its settled designs. It is not a question of probabilities, but of time. And whom will a just God hold responsible for all these results? All who despise and persecute men on account of their complexion; all who endorse a slaveholding religion as genuine; all who give the right hand of Christian fellowship to men whose hands are stained with the blood of the slave; all who regard material prosperity as paramount to moral integrity, and the law of the land as above the law of God; all who are either hostile or indifferent to the Anti-Slavery movement; and all who advocate the necessity of making compromises with the Slave Power, in order that the Union may receive no detriment.

In itself, Slavery has no resources and no strength. Isolated and alone, it could not stand an hour; and, therefore, further aggression and conquest would be impossible.

Says the Editor of the Marysville (Tenn.) Intelligencer, in an article on the character and condition of the slave population:

"We of the South are emphatically surrounded by dangerous class of beings—degraded, stupid savages—who, if they could but once entertain the idea that immediate and unconditional death would not be their portion, would re-enact the St. Domingo tragedy. But the consciousness, with all their stupidity, that a ten-fold force, superior in discipline, if not in barbarity, would gather from the four corners of the United States and slaughter them, keeps them in subjection. But, to the non-slaveholding States, particularly, we are indebted for a permanent safeguard against insurrection. Without their assistance, the while population of the South would be too weak to quiet that insane desire for liberty which is ever ready to act itself out with every rational creature."

In the debate in Congress on the resolution to censure John Quincy Adams, for presenting a petition for the dissolution of the Union, Mr. Underwood, of Kentucky, said:

"They (the South) were the weaker portion, were in the minority. The North could do what they pleased with them; they could adopt their own measures. All he asked was, that they would let the South know what those measures were. One thing he knew well; that State, which he in part represented, had perhaps a deeper interest in this subject than any other, except Maryland and a small portion of Virginia. And why? Because he knew that to dissolve the Union, and separate the different States composing the confederacy, making the Ohio River and the Mason and Dixon's line the boundary line, he knew as soon as that was done, Slavery was done in Kentucky, Maryland and a large portion of Virginia, and it would extend to all the States South of this line. The dissolution of the Union was the dissolution of Slavery. It has been the common practice for Southern men to get up on this floor, and say, 'Touch this subject, and we will dissolve this Union as a remedy.' Their remedy was the destruction of the thing which they wished to save, and any sensible man could see it. If the Union was dissolved into two parts, the slave would cross the line, and then turn round and curse the master from the other shore."

The declaration of Mr. Underwood as to the entire dependence of the slave masters on the citizens of the nominally Free States to guard their plantations, and secure them against desertion, is substantially confirmed by Thomas D. Arnold, of Tennessee, who, in a speech on the name subject, assures us that they are equally dependent on the North for personal protection against their slaves. In assigning his reasons for adhering to the Union, Mr. Arnold makes use of the following language:

"The Free States had a majority of 44 in that House. Under the new census, they would have 53. The cause of the slaveholding States was getting weaker and weaker, and what were they to do? He would ask his Southern friends what the South had to rely on, if the Union were dissolved? Suppose the dissolution could be peaceably effected (if that did not involve a contradiction in terms), what had the South to depend upon? All the crowned heads were against her. A million of slaves were ready to rise and strike for freedom at the first tap of the drum. If they were cut loose from their friends at the North (friends that ought to be, and without them, the South had no friends), whither were they to look for protection? How were they to sustain an assault from England or France, with the cancer at their vitals? The more the South reflected, the more clearly she must see that she has a deep and vital interest in maintaining the Union."
