“ The Constitution of the United States does not purport to secure the blessings of liberty to all men within the limits of the Union, but to the people who established it, and their posterity. It could not have done more; for the slaveholding States could not, and ought not, to have entered a Union which would have conferred freedom upon men incapable of receiving it, or which would have required those States to surrender to a central and insufficient power that trust of custody and care which, in the providence of God, had been cast upon their more effectual local authority. ”
