6. Distinguished statesmen and jurists in the slaveholding states, have
conceded the power of Congress to abolish slavery in the District. The
testimony of Messrs. Doddridge, Powell, and Alexander, of Virginia,
Chief Justice Cranch, and Judges Morsell and Van Ness, of the District,
has already been given. In the debate in Congress on the memorial of the
Society of Friends, in 1790, Mr. Madison, in speaking of the territories
of the United States, explicitly declared, from his own knowledge of the
views of the members of the convention that framed the constitution, as
well as from the obvious import of its terms, that in the territories
"Congress have certainly the power to regulate the subject of slavery."
Congress can have no more power over the territories than that of
"exclusive legislation in all cases whatsoever," consequently, according
to Mr. Madison, "it has certainly the power to regulate the subject of
slavery in the" _District_. In March, 1816, John Randolph introduced a
resolution for putting a stop to the domestic slave trade within the
District. December 12, 1827, Mr. Barney, of Maryland, presented a
memorial for abolition in the District, and moved that it be printed.
Mr. McDuffie, of South Carolina, objected to the printing, but
"expressly admitted the right of Congress to grant to the people of the
District any measures which they might deem necessary to free themselves
from the deplorable evil."--(See letter of Mr. Claiborne, of
Mississippi, to his constituents, published in the Washington Globe, May
9, 1836.) The sentiments of Henry Clay on the subject are well known. In
a speech before the U.S. Senate, in 1836, he declared the power of
Congress to abolish slavery in the District "unquestionable." Messrs.
Blair, of Tennessee, Chilton, Lyon, and Richard M. Johnson, of Kentucky,
