This habit of setting up man's law, instead of God's law, as the standard of conduct, is strikingly manifested in the fact, that on the ground, that the Federal Constitution binds the citizens of the United States to perpetuate slavery, or at least, not to meddle with it, we are, both at the North and the South, called on to forbear from all efforts to abolish it. The exertions made to discover in that instrument, authority for slavery, and authority against endeavors to abolish it, are as great, anxious, and unwearied, as if they who made them, thought that the fortunate discovery would settle for ever the great question which agitates our country--would nullify all the laws of God against slavery--and make the oppression of our colored brethren, as long as time shall last, justifiable and praiseworthy. But this discovery will never be made; for the Constitution is not on the side of the slaveholder. If it were, however, it would clothe him with no moral right to act in opposition to the paramount law of God. It is not at all necessary to the support of my views, in this communication, to show that the Constitution was not designed to favor slavery; and yet, a few words to this end may not be out of place. A treaty between Great Britain and Turkey, by the terms of which the latter should be prohibited from allowing slaves to be brought within her dominions, after twenty years from its date, would, all will admit, redound greatly to the credit of Great Britain. To be sure, she would not have done as much for the cause of humanity, as if she had succeeded in bringing the further indulgence of the sin within the limits of a briefer period, and incomparably less than if she had succeeded in reconciling the Sublime Porte to her glorious and emphatically English doctrines of immediate emancipation. But still she would deserve some praise--much more than if she had done nothing in this respect. Now, for my present purpose, and many of our statesmen say, for nearly all purposes, the Federal Constitution is to be regarded as a treaty between sovereign States. But how much more does this treaty do for the abolition of slavery, than that on which we were, a moment since, bestowing our praise! It imposes a prohibition similar to that in the supposed treaty between Great Britain and Turkey, so that no slaves have been allowed to be introduced into the United States since the year 1808. It goes further, and makes ample provision for the abolition and prevention of slavery in every part of the nation, save these States; so that the District of Columbia and the national territories can be cleared forever of slavery, whenever a majority of the parties, bound by the treaty, shall desire it. And it goes still farther, and clothes this majority with the power of regulating commerce between the States, and consequently, of prohibiting their mutual traffic in "the bodies and souls of men." Had this treaty gone but one step farther, and made an
