Every one knows that the "Madison Papers" contain a Report, from the pen of James Madison, of the Debates in the Old Congress of the Confederation and in the Convention which formed the Constitution of the United States. We have extracted from them, in these pages, all the Debates on those clauses of the Constitution which relate to slavery. To these we have added all that is found, on the same topic, in the Debates of the several State Conventions which ratified the Constitution: together with so much of the Speech of Luther Martin before the Legislature of Maryland, and of the Federalist, as relate to our subject; with some extracts, also, from the Debates of the first Federal Congress on Slavery. These are all printed without alteration, except that, in some instances, we have inserted in brackets, after the name of a speaker, the name of the State from which he came. The notes and italics are those of the original, but the editor has added two notes on [page 38], which are marked as his, and we have taken the liberty of printing in capitals one sentiment of Rufus King's, and two of James Madison's—a distinction which the importance of the statements seemed to demand—otherwise we have reprinted exactly from the originals.

These extracts develop most clearly all the details of that "compromise," which was made between freedom and slavery, in 1787; granting to the slaveholder distinct privileges and protection for his slave property, in return for certain commercial concessions on his part toward the North. They prove also that the Nation at large were fully aware of this bargain at the time, and entered into it willingly and with open eyes.

We have added the late "Address of the American Anti-Slavery Society," and the Letter of FRANCIS JACKSON to Governor BRIGGS, resigning his commission of Justice of the Peace—as bold and honorable protests against the guilt and infamy of this National bargain, and as proving most clearly the duty of each individual to trample it under his feet. The clauses of the Constitution to which we refer as of a pro-slavery character are the following :—

ART. 1, SECT. 2.—Representatives and direct taxes shall be apportioned among the several States, which may be included within this Union, according to their respective numbers, which shall be determined by adding to the whole number of free persons, including those bound to service for a term of years, and excluding Indians not taxed, three-fifths of all other persons.

ART. 1, SECT. 8.—Congress shall have power ... to suppress insurrections.

ART. 1, SECT. 9.—The migration or importation of such persons as any of the States now existing, shall think proper to admit, shall not be prohibited by the Congress, prior to the year one thousand eight hundred and eight: but a tax or duty may be imposed on such importation, not exceeding ten dollars for each person.

ART. 4, SECT. 2.—No person, held to service or labor in one State, under the laws thereof, escaping into another, shall, in consequence of any law or regulation therein, be discharged from such service or labor; but shall be delivered up on claim of the party to whom such service or labor may be due.

ART. 4, SECT. 4.—The United States shall guarantee to every State in this Union a republican form of government; and shall protect each of them against invasion; and, on application of the legislature, or of the executive, (when the legislature cannot be convened) against domestic violence.

The first of these clauses, relating to representation, confers on a slaveholding community additional political power for every slave held among them, and thus tempts them to continue to uphold the system: the second and the last, relating to insurrection and domestic violence, perfectly innocent in themselves—yet being made with the fact directly in view that slavery exists among us, do deliberately pledge the whole national force against the unhappy slave if he imitate our fathers and resist oppression—thus making us partners in the guilt of sustaining slavery: the third, relating to the slave-trade, disgraces the nation by a pledge not to abolish that traffic till after twenty years, without obliging Congress to do so even then, and thus the slave-trade may be legalized to-morrow if Congress choose: the fourth is a promise on the part of the whole Nation to return fugitive slaves to their masters, a deed which God's law expressly condemns and which every noble feeling of our nature repudiates with loathing and contempt.
