This recital would appear to have been carefully introduced, in order to prevent any misunderstanding of the motive which induced the Legislature to pass the law, and places it distinctly upon the interest and convenience of the white population--excluding the inference that it might have been intended in any degree for the benefit of the other. And in the act of 1784, by which the issue of slaves, born after the time therein mentioned, were to be free at a certain age, the section is again introduced by a preamble assigning similar motive for the act. It is in these words: "Whereas sound policy requires that the abolition of slavery should be effected as soon as may be consistent with the rights of individuals, and the public safety and welfare"--showing that the right of property in the master was to be protected, and that the measure was one of policy, and to prevent the injury and inconvenience, to the whites, of a slave population in the State. And still further pursuing its legislation, we find that in the same statute passed in 1774, which prohibited the further importation of slaves into the State, there is also a provision by which any negro, Indian, or mulatto servant, who was found wandering out of the town or place to which he belonged, without a written pass such as is therein described, was made liable to be seized by any one, and taken before the next authority to be examined and delivered up to his master--who was required to pay the charge which had accrued thereby. And a subsequent section of the same law provides, that if any free negro shall travel without such pass, and shall be stopped, seized, or taken up, he shall pay all charges arising thereby. And this law was in full operation when the Constitution of the United States was adopted, and was not repealed till 1797. So that up to that time free negroes and mulattoes were associated with servants and slaves in the police regulations established by the laws of the State. And again, in 1833, Connecticut passed another law, which made it penal to set up or establish any school in that State for the instruction of persons of the African race not inhabitants of the State or to instruct or teach in any such school or institution, or board or harbor for that purpose, any such person, without the previous consent in writing of the civil authority of the town in which such school or institution might be.
