3. It has been conceded by the citizens of the District. A petition for the gradual abolition of slavery in the District, signed by nearly eleven hundred of its citizens, was presented to Congress, March 24, 1837. Among the signers to this petition, were Chief Justice Cranch, Judge Van Ness, Judge Morsel, Prof. J.M. Staughton, Rev. Dr. Balch, Rev. Dr. Keith, John M. Munroe, and a large number of the most influential inhabitants of the District. Mr. Dickson, of New York, asserted on the floor of Congress in 1835, that the signers of this petition owned more than half of the property in the District. The accuracy of this statement has never been questioned.
This power has been conceded by grand juries of the District. The grand jury of the county of Alexandria, at the March term 1802, presented the domestic slave trade as a grievance, and said, "We consider these grievances demanding legislative redress." Jan. 19, 1829, Mr. Alexander, of Virginia, presented a representation of the grand jury in the city of Washington, remonstrating against "any measure for the abolition of slavery within said District, unless accompanied by measures for the removal of the emancipated from the same;" thus, not only conceding the power to emancipate slaves, but affirming an additional power, that of excluding them when free. See Journal H.R. 1828-9, p. 174.
4. This power has been conceded by State Legislatures. In 1828 the Legislature of Pennsylvania instructed their Senators in Congress "to procure, if practicable, the passage of a law to abolish slavery in the District of Columbia." Jan. 28, 1829, the House of Assembly of New York passed a resolution, that their "Senators in Congress be instructed to make every possible exertion to effect the passage of a law for the abolition of Slavery in the District of Columbia." In February, 1837, the Senate of Massachusetts "Resolved, That Congress having exclusive legislation in the District of Columbia, possess the right to abolish slavery and the slave trade therein, and that the early exercise of such right is demanded by the enlightened sentiment of the civilized world, by the principles of the revolution, and by humanity." The House of Representatives passed the following resolution at the same session: "Resolved, That Congress having exclusive legislation in the District of Columbia, possess the right to abolish slavery in said District, and that its exercise should only be restrained by a regard to the public good."
November 1, 1837, the Legislature of Vermont, "Resolved, that Congress have the full power by the constitution to abolish slavery and the slave trade in the District of Columbia, and in the territories." The Legislature of Vermont passed in substance the same resolution, at its session in 1836.
May 30, 1836, a committee of the Pennsylvania Legislature reported the following resolution: "Resolved, That Congress does possess the constitutional power, and it is expedient to abolish slavery and the slave trade within the District of Columbia."
In January, 1836, the Legislature of South Carolina "Resolved, That we should consider the abolition of slavery in the District of Columbia as a violation of the rights of the citizens of that District derived from the implied conditions on which that territory was ceded to the General Government." Instead of denying the constitutional power, they virtually admit its existence, by striving to smother it under an implication. In February, 1836, the Legislature of North Carolina "Resolved, That, although by the Constitution all legislative power over the District of Columbia is vested in the Congress of the United States, yet we would deprecate any legislative action on the part of that body towards liberating the slaves of that District, as a breach of faith towards those States by whom the territory was originally ceded, and will regard such interference as the first step towards a general emancipation of the slaves of the South." Here is a full concession of the power, February 2, 1836, the Virginia Legislature passed unanimously the following resolution: "Resolved, by the General Assembly of Virginia, that the following article be proposed to the several states of this Union, and to Congress, as an amendment of the Constitution of the United States: 'The powers of Congress shall not be so construed as to authorize the passage of any law for the emancipation of slaves in the District of Columbia, without the consent of the individual proprietors thereof, unless by the sanction of the Legislatures of Virginia and Maryland, and under such conditions as they shall by law prescribe.'"
Fifty years after the formation of the United States constitution the states are solemnly called upon by the Virginia Legislature, to amend that instrument by a clause asserting that, in the grant to Congress of "exclusive legislation in all cases whatsoever" over the District, the "case" of slavery is not included!! What could have dictated such a resolution but the conviction that the power to abolish slavery is an irresistible interference from the constitution as it is. The fact that the same legislature passed afterward a resolution, though by no means unanimously, that Congress does not possess the power, abates not a tittle of the testimony in the first resolution. March 23d, 1824, "Mr. Brown presented the resolutions of the General Assembly of Ohio, recommending to Congress the consideration of a system for the gradual emancipation of persons of color held in servitude in the United States." On the same day, "Mr. Noble, of Indiana, communicated a resolution from the legislature of that state, respecting the gradual emancipation of slaves within the United States." Journal of the United States Senate, for 1824-5, p. 231.
The Ohio and Indiana resolutions, by taking for granted the general power of Congress over the subject of slavery, do virtually assert its special power within its exclusive jurisdiction.
5. The power of Congress to abolish slavery in the District, has been conceded by bodies of citizens in the slave states. The petition of eleven hundred citizens of the District of Columbia, in 1827, has been already mentioned. "March 5, 1830, Mr. Washington presented a memorial of inhabitants of the county of Frederick, in the state of Maryland, praying that provision may be made for the gradual abolition of slavery in the District of Columbia." Journal H.R. 1829-30, p. 358.
March 30, 1828. Mr. A.H. Shepperd, of North Carolina, presented a memorial of citizens of that state, "praying Congress to take measures fur the entire abolition of slavery in the District of Columbia." Journal H.R. 1829-30, p. 379.
