The delegates from South Carolina and Georgia distinctly avowed that, without this guarantee of protection to their property in slaves, they would not yield their assent to the Constitution; and the freemen of the North, reduced to the alternative of departing from the vital principle of their liberty, or of forfeiting the Union itself, averted their faces, and with trembling hand subscribed the bond.

Twenty years passed away—­the slave markets of the South were saturated with the blood of African bondage, and from midnight of the 31st of December, 1807, not a slave from Africa was suffered ever more to be introduced upon our soil.  But the internal traffic was still lawful, and the breeding States soon reconciled themselves to a prohibition which gave them the monopoly of the interdicted trade, and they joined the full chorus of reprobation, to punish with death the slave-trader from Africa, while they cherished and shielded and enjoyed the precious profits of the American slave-trade exclusively to themselves.

Perhaps this unhappy result of their concession had not altogether escaped the foresight of the freemen of the North; but their intense anxiety for the preservation of the whole Union, and the habit already formed of yielding to the somewhat peremptory and overbearing tone which the relation of master and slave welds into the nature of the lord, prevailed with them to overlook this consideration, the internal slave-trade having scarcely existed while that with Africa had been allowed.  But of one consequence which has followed from the slave representation, pervading the whole organic structure of the Constitution, they certainly were not prescient; for if they had been, never—­no, never would they have consented to it.

The representation, ostensibly of slaves, under the name of persons, was in its operation an exclusive grant of power to one class of proprietors, owners of one species of property, to the detriment of all the rest of the community.  This species of property was odious in its nature, held in direct violation of the natural and inalienable rights of man, and of the vital principles of Christianity; it was all accumulated in one geographical section of the country, and was all held by wealthy men, comparatively small in numbers, not amounting to a tenth part of the free white population of the States in which it was concentrated.

In some of the ancient, and in some modern republics, extraordinary political power and privileges have been invested in the owners of horses; but then these privileges and these powers have been granted for the equivalent of extraordinary duties and services to the community, required of the favoured class.  The Roman knights constituted the cavalry of their armies, and the bushels of rings gathered by Hannibal from their dead bodies, after the battle of Cannae, amply prove that the special powers conferred upon them were no gratuitous grants.  But in the Constitution
