... The general then said he would make a few observations on the objections which the gentleman had thrown out on the restrictions that might be laid on the African trade after the year 1808. On this point your delegates had to contend with the religious and political prejudices of the Eastern and Middle States, and with the interested and inconsistent opinion of Virginia, who was warmly opposed to our importing more slaves. I am of the same opinion now as I was two years ago, when I used the expressions the gentleman has quoted—that, while there remained one acre of swampland uncleared of South Carolina, I would raise my voice against restricting the importation of negroes. I am so thoroughly convinced as that gentleman is, that the nature of our climate, and the flat, swampy situation of our country, obliges us to cultivate our lands with negroes, and that without them South Carolina would soon be a desert waste.
You have so frequently heard my sentiments on this subject that I need not now repeat them. It was alleged, by some of the members who opposed an unlimited importation, that slaves increased the weakness of any state who admitted them; that they were a dangerous species of property, which an invading enemy could easily turn against ourselves and the neighboring states; and that, as we were allowed a representation for them in the House of Representatives, our influence in government would be increased in proportion as we were less able to defend ourselves. "Show some period," said the members from the Eastern States, "when it may be in our power to put a stop, if we please, to the importation of this weakness, and we will endeavor, for your convenience, to restrain the religious and political prejudices of our people on this subject." The Middle States and Virginia made us no such proposition; they were for an immediate and total prohibition. We endeavored to obviate the objections that were made in the best manner we could, and assigned reasons for our insisting on the importation, which there is no occasion to repeat, as they must occur to every gentleman in the house; a committee of the states was appointed in order to accommodate this matter, and, after a great deal of difficulty, it was settled on the footing recited in the Constitution.
By this settlement we have secured an unlimited importation of negroes for twenty years. Nor is it declared that the importation shall be then stopped; it may be continued. We have a security that the general government can never emancipate them, for no such authority is granted; and it is admitted, on all hands, that the general government has no powers but what are expressly granted by the Constitution, and that all rights not expressed were reserved by the several states. We have obtained a right to recover our slaves in whatever part of America they may take refuge, which is a right we had not before. In short, considering all circumstances, we have made the best terms for the security of this species of property it was in our power to make. We would have made better if we could; but, on the whole, I do not think them bad.[570]
Mr. Madison said in the Virginia ratifying Convention, June 17, 1787:
Mr. Chairman—I should conceive this clause to be impolitic, if it were one of those things which could be excluded without encountering greater evils.—The southern states would not have entered into the union of America, without the temporary permission of that trade. And if they were excluded from the union, the consequences might be dreadful to them and to us. We are not in a worse situation than before. That traffic is prohibited by our laws, and we may continue the prohibition. The union in general is not in a worse situation. Under the articles of confederation, it might be continued forever: But by this clause an end may be put to it after twenty years. There is therefore an amelioration of our circumstances. A tax may be laid in the mean time; but it is limited, otherwise congress might lay such a tax on slaves as will amount to manumission. Another clause secures us that property which we now possess. At present, if any slave elopes to any of those states where slaves are free, he becomes emancipated by their laws. For the laws of the states are uncharitable to one another in this respect. But in this constitution, "no person held to service, or labor, in one state, under the laws thereof, escaping into another, shall in consequence of any law or regulation therein, be discharged from such service or labor; but shall be delivered up on claim of the party to whom such service or labor may be due."—This clause was expressly inserted to enable owners of slaves to reclaim them. This is a better security than any that now exists. No power is given to the general government to interpose with respect to the property in slaves now held by the states. The taxation of this state being equal only to its representation, such a tax cannot be laid as he supposes. They cannot prevent the importation of slaves for twenty years; but after that period they can. The gentlemen from South-Carolina and Georgia argued in this manner:—"We have now liberty to import this species of property, and much of the property now possessed has been purchased, or otherwise acquired, in contemplation of improving it by the assistance of imported slaves. What would be the consequence of hindering us from it? The slaves of Virginia would rise in value, and we would be obliged to go to your markets." I need not expatiate on this subject. Great as the evil is, a dismemberment of the union would be worse. If those states should disunite from the other states, for not indulging them in the temporary continuance of this traffic, they might solicit and obtain aid from foreign powers....
(The 2d, 3d, and 4th clauses read.)
... Mr. Madison replied, that even the southern states, who were most affected, were perfectly satisfied with this provision, and dreaded no danger to the property they now hold. It appeared to him, that the general government would not intermeddle with that property for twenty years, but to lay a tax on every slave imported, not exceeding ten dollars; and that after the expiration of that period they may prohibit the traffic altogether. The census in the constitution was intended to introduce equality in the burdens to be laid on the community.—No gentleman objected to laying duties, imposts, and exercises, uniformly. But uniformity of taxes would be subversive of the principles of equality: For that it was not possible to select any article which would be easy for one state, but what would be heavy for another.—...[571]
In 1789 Madison said:
I conceive the constitution, in this particular, was formed in order that the Government, whilst it was restrained from laying a total prohibition, might be able to give some testimony of the sense of America with respect to the African trade. We have liberty to impose a tax or duty upon the importation of such persons, as any of the States now existing shall think proper to admit; and this liberty was granted, I presume, upon two considerations: The first was, that until the time arrived when they might abolish the importation of slaves, they might have an opportunity of evidencing their sentiments on the policy and humanity of such a trade. The other was, that they might be taxed in due proportion with other articles imported; for if the possessor will consider them as property, of course they are of value, and ought to be paid for.[572]
According to Elliot, Spaight said on July 26, 1787:
Mr. Spaight answered, that there was a contest between the Northern and Southern States; that the Southern States, whose principal support depended on the labor of slaves, would not consent to the desire of the Northern States to exclude the importation of slaves absolutely; that South Carolina and Georgia insisted on this clause, as they were now in want of hands to cultivate their lands; that in the course of twenty years they would be fully supplied; that the trade would be abolished then, and that, in the mean time, some tax or duty might be laid on....
Mr. Spaight further explained the clause. That the limitation of this trade to the term of twenty years was a compromise between the Eastern States and the Southern States. South Carolina and Georgia wished to extend the term. The Eastern States insisted on the entire abolition of the trade. That the state of North Carolina had not thought proper to pass any law prohibiting the importation of slaves, and therefore its delegation in the Convention did not think themselves authorized to contend for an immediate prohibition of it....[573]
In the House of Representatives on February 12, 1790:
Mr. Baldwin was sorry the subject had ever been brought before Congress, because it was of a delicate nature as it respected some of the States. Gentlemen who had been present at the formation of the Constitution could not avoid the recollection of the pain and difficulty which the subject caused in that body. The members from the Southern States were so tender upon this point, that they had well nigh broken up without coming to any determination; however, from the extreme desire of preserving the Union, and obtaining an efficient Government, they were induced mutually to concede, and the Constitution jealously guarded what they agreed to. If gentlemen look over the footsteps of that body, they will find the greatest degree of caution used to imprint them, so as not to be easily eradicated; but the moment we go to jostle on that ground, I fear we shall feel it tremble under our feet. Congress have no power to interfere with the importation of slaves beyond what is given in the ninth section of the 1st article of the Constitution; everything else is interdicted to them in the strongest terms. If we examine the constitution, we shall find the expressions relative to this subject cautiously expressed, and more punctiliously guarded than any other part, "The migration or importation of such persons shall not be prohibited by Congress." But lest this should not have secured the object sufficiently, it is declared, in the same section, "That no capitation or direct tax shall be laid, unless in proportion to the census;" this was intended to prevent Congress from laying any special tax upon negro slaves, as they might, in this way, so burthen the possessors of them as to induce a general emancipation. If we go on to the fifth article, we shall find the first and fifth clauses of the ninth section of the first article restrained from being altered before the year 1808.[574]
