Daniel Webster on the Slave Trade

I deem it my duty on this occasion to suggest, that the land is not yet wholly free from the contamination of a traffic, at which every feeling of humanity must for ever revolt, - I mean the African slave-trade. Neither public sentiment, nor the law, has hitherto been able entirely to put an end to this odious and abominable trade. At the moment when God in his mercy has blessed the Christian world with a universal peace, there is reason to fear, that, to the disgrace of the Christian name and character, new efforts are making for the extension of this trade by subjects and citizens of Christian states, in whose hearts there dwell no sentiments of humanity or of justice, and over whom neither the fear of God nor the fear of man exercises a control.

In the sight of our law, the African slave-trader is a pirate and a felon; and in the sight of Heaven, an offender beyond the ordinary depth of human guilt. There is no brighter page of our history, than that which records the measures which have been adopted by the government at an early day, and at different times since, for the suppression of this traffic; and I would call on all the true sons of New England to cooperate with the laws of man, and the justice of Heaven.

If there be, within the extent of our knowledge or influence, any participation in this traffic, let us pledge ourselves here, upon the rock of Plymouth, to extirpate and destroy it. It is not fit that the land of the Pilgrims should bear the shame longer. I hear the sound of the hammer, I see the smoke of the furnaces where manacles and fetters are still forged for human limbs. I see the visages of those who by stealth and at midnight labor in this work of hell, foul and dark, as may become the artificers of such instruments of misery and torture. Let that spot be purified, or let it cease to be of New England. Let it be purified, or let it be set aside from the Christian world; let it be put out of the circle of human sympathies and human regards, and let civilized man henceforth have no communion with it.
