"The only two clauses in the Constitution which point to this race treat them as persons whom it was _morally_ lawful to deal in as articles of property and to hold as slaves. "The change in public opinion and feeling in relation to the African race which has taken place since the adoption of the Constitution cannot change its construction and meaning, and it must be construed and administered now according to its true meaning and intention when it was formed and adopted. "The plaintiff, having admitted (by his demurrer to the plea in abatement) that his ancestors were imported from Africa and sold as slaves, he is not a citizen of the State of Missouri according to the Constitution of the United States, and was not entitled to sue in that character in the Circuit Court. "The clause in the Constitution authorizing Congress to make all needful rules and regulations for the government of the territory and other property of the United States applies only to territory within the chartered limits of some of the States when they were colonies of Great Britain, and which was surrendered by the British Government to the old Confederation of States in the treaty of peace. It does not apply to territory acquired by the present Federal Government, by treaty or conquest, from a foreign nation. "The United States, under the present Constitution, cannot acquire territory to be held as a colony, to be governed at its will and pleasure. But it may acquire and may govern it as a Territory until it has a population which, in the judgment of Congress, entitles it to be admitted as a State of the Union. "During the time it remains a Territory Congress may legislate over it within the scope of its constitutional powers in relation to citizens of the United States--and may establish a territorial government--and the form of this local government must be regulated by the discretion of Congress--but with powers not exceeding those which Congress itself, by the Constitution, is authorized to exercise over citizens of the United States, in respect to their rights of persons or rights of property. "The Territory thus acquired is acquired by the people of the United States for their common and equal benefit, through their agent and trustee, the Federal Government. Congress can exercise no power over the rights of persons or property of a citizen in the Territory which is prohibited by the Constitution. The government and its citizens, whenever the Territory is open to settlement, both enter it with their respective rights defined and limited by the Constitution. "Congress has no right to prohibit the citizens of any particular State or States from taking up their home there, while it permits citizens of other States to do so. Nor has it a right to give privileges to one class of citizens which it refuses to another. The territory is acquired for their equal and common benefit--and if open to any it must be open to all upon equal and the same terms.
