" No free Negro, or Mulatto, not residing in this state at the time of the adoption of this constitution, shall come, reside, or be within this state, or hold any real estate, or make any contracts, or maintain any suit therein; an the Legislative Assembly shall provide by penal laws, for the removal, by public officers, of all such Negroes, and Mulattos, and for their effectual exclusion from the state, and for the punishment of persons who shall bring them into the state, or employ, or harbor them.”
Oregon Constitution 1833 - Article I Section 35 (The free Negro clause was repealed, November 3, 1926.)
