7. Assuming that there is in Congress a discretionary or sovereign power to govern the territories, sound policy requires such government to be administered in that "spirit of amity and mutual deference and concession," in which the Constitution itself was conceived and adopted; and the absolute prohibition of slavery in all the national territory in which Free States and Slave States have a common right and common interest, is in direct conflict with the spirit of the Constitution.

Lastly—Compromise is demonstrated to be the principle of the Constitution and the policy of the Federal government in regard to slavery. A Congressional geographical line is not the true mode of compromise, as such a line implies the right of slavery to exclusive possession on one side of the geographical line, and is therefore in favor of slavery and against freedom. The question as a constitutional one, is not a question between freedom and slavery, but a question of constitutional authority, growing out of the clear and fundamental distinction in the Constitution, between the powers of legislation for local or domestic purposes and the like powers for national or Federal purposes. The true principle of compromise on the part of the Federal government is neutrality, non-interference, non-intervention, or the leaving of the question to be fairly determined in the local jurisdiction where it arises. A geographical line is arbitrary and not adapted to varying circumstances or events; the principle of local sovereignty involved in that of national non-intervention, is self-adjusting and of universal application; it applies to all cases and all times, and is in itself, the only principle consistent with the theory of the government, which is that the people of each State and community have the right and capacity to regulate their own internal affairs, subject only to their respective fundamental laws or Constitutions of government and to the nation's organic law. This principle was the basis of the compromise laws of 1850, and of the erasure of the Missouri line in 1854, and has been endorsed by large majorities of the people both North and South.

Now, how do the parties and candidates seeking from the people the power to control the Federal government, stand on this great subject that divides the nation?

I shall not presume to weary your patience by dwelling on this question. Men who read and think with calm unbiased minds, cannot fail to see how they stand.

I have now only to say:

1. Looking to the men who formed it, and who lead it, the platform on which it stands, and the end which it contemplates, I regard the organization headed by Breckinridge and Lane as essentially a sectional slavery extension party, bound through the Federal judiciary, backed by the Federal government, to extend slavery into all the territories of the United States, with or without the assent of the people, and if need be to accomplish this end, bound to legalize slavery under the Federal Constitution in every State of the Union, and to open the floodgates of the African slave trade under the protection of the national banner. This is the logical end of the Breckinridge and Lane platform. Its practical end will be the destruction of the American Union, for no man in his senses can believe that the Federal government, either through its President, or its Congress, or its Supreme Court, can ever make negro slavery lawful for one hour, where the free white people of any State will that it shall not be. If slaveholders are ever to reach the throne of national power on this continent, which the Breckinridge party are aiming to erect for them, they will wade to that throne through battle fields flowing with human blood.

This Breckinridge and Lane party holds within its bosom the rankest disunionists and most ultra advocates of the African slave trade. Its true watch cry, whatever it may pretend in the North, is "National Slavery or Disunion."

With this view of the Breckinridge party, I cannot therefore say that I admired the good taste or consistency of my Republican friends, when in this city a few nights ago, they encouraged by loud applause, the virulent harangue of Jesse D. Bright, the Indiana leader of the Breckinridge faction, not I presume because they approved his sentiments, but because he abused Stephen A. Douglas.

2. Looking to the men who formed it, and who now represent it as its leading oracles, Seward, Hale, Sumner, Wilson, Chase, Giddings, Wade, Lovejoy, not forgetting John A. Andrews of Massachusetts, with his negro guard of wide-awakes, nor excepting John Brown, the martyr, nor excepting the comparatively unknown Abraham Lincoln, whom the crisis of the divided house has made famous—and looking also to the Philadelphia and Chicago platforms on which the party stands, with their logical inconsistencies, and the end which those platforms, as well as the public addresses and working machinery of their advocates contemplate—I regard the so-called Republican party, whose candidates are Lincoln and Hamlin, as essentially a sectional, slavery prohibition and slavery abolition party, bound by political action, through the power of the Federal government; first, to prohibit slavery in all the territories of the United States; second, to admit no more Slave States, and ultimately by State action and Federal action too, when the Free States have become three-fourths of the whole, and sufficiently powerful to make the Federal Constitution what they please, to abolish slavery in all the States, so that, to use the language of William H. Seward at Chicago, on 2d October instant, "Civilization may be maintained and carried on, on this continent by Federal States, based on the principles of free soil, free labor, free speech, equal rights and universal suffrage." This is the creed of the Republican party as declared by Mr. Seward, and he affirms that it is a positive party that will take no more compromises in geographical lines or squatter sovereignties.

This is the logical end of the platforms of the Republican party; the practical end, following the attempt to realize the other, will be disunion, with all the dire results portrayed by Daniel Webster, when in that great effort of his majestic intellect, his defence of the American Union, he prayed that when "his eyes should be turned to behold for the last time the sun in heaven, he might not see him shining on the broken and dishonored fragments of a once glorious Union; on States dissevered, discordant, belligerent; on a land rent with civil feuds, or drenched, it may be, in fraternal blood!"
