all blacks and people of color that shall be born within the District of
Columbia, or whose mothers shall be the property of any person residing
within said District, shall be free, the males at the age of ----, and
the females at the age of ----. The main question being taken that the

of its alleged _inexpediency_ alone, and not because Congress lacked the

appointed to inquire into the existence of an inhuman and illegal
traffic in slaves, carried on in and through the District of Columbia,
and to report whether any and what measures are necessary for _putting a

Messrs. Barney of Md., Armstrong of Va., A.H. Shepperd of N.C., Blair of
Tenn., Chilton and Lyon of Ky., Johns of Delaware, and others from slave
states.

the United States, has by the constitution exclusive jurisdiction over
the District, and has power upon this subject, (_slavery_) as upon all
other subjects of legislation, to exercise _unlimited discretion_."
