One of these clauses reserves to each of the thirteen States the right to import slaves until the year 1808, if it thinks proper. And the importation which it thus sanctions was unquestionably of persons of the race of which we are speaking, as the traffic in slaves in the United States had always been confined to them. And by the other provision the States pledge themselves to each other to maintain the right of property of the master, by delivering up to him any slave who may have escaped from his service, and be found within their respective territories. By the first above-mentioned clause, therefore, the right to purchase and hold this property is directly sanctioned and authorized for twenty years by the people who framed the Constitution. And by the second, they pledge themselves to maintain and uphold the right of the master in the manner specified, as long as the Government they then formed should endure. And these two provisions show, conclusively, that neither the description of persons therein referred to, nor their descendants, were embraced in any of the other provisions of the Constitution; for certainly these two clauses were not intended to confer on them or their posterity the blessings of liberty, or any of the personal rights so carefully provided for the citizen. No one of that race had ever migrated to the United States voluntarily; all of them had been brought here as articles of merchandise. The number that had been emancipated at that time were but few in comparison with those held in slavery; and they were identified in the public mind with the race to which they belonged, and regarded as a part of the slave population rather than the free. It is obvious that they were not even in the minds of the framers of the Constitution when they were conferring special rights and privileges upon the citizens of a State in every other part of the Union. Indeed, when we look to the condition of this race in the several States at the time, it is impossible to believe that these rights and privileges were intended to be extended to them.
