The constn as agreed to till a fortnight before the convention rose was such a one as he wd have set his hand & heart to.... with respect to the importn of slaves it was left to Congress, this disturbed the 2 Souther-most states who knew that Congress would immediately suppress the importn of slaves, those 2 states therefore struck up a bargain with the 3. N. Engld, states, if they would join to admit slaves for some years, the 2 Southernmost states wd join in changing the clause which required 2/3 of the legislature in any vote. It was done, these articles were changed accordingly, & from that moment the two S. states and the 3 Northern ones joined Pen. Jers. & Del. & made the majority 8. to 3. against us instead of 8. to 3. for us as it had been thro' the whole Convention. under this coalition the great principles of the Constn were changed in the last days of the Convention.[575]
The following debate on this subject took place in the House of Representatives, June 16-20, 1798:
Mr. B(aldwin). thought the 9th section, forbidding Congress to prohibit the migration, &c., was directly opposed to the principles of this bill. He recollected very well that when the 9th section of the Constitution was under consideration in the Convention, the delegates from some of the Southern States insisted that the prohibition of the introduction of slaves should be left to the State Governments; it was found expedient to make this provision in the Constitution; there was an objection to the use of the word slaves, as Congress by none of their acts had ever acknowledged the existence of such a condition. It was at length settled on the words as they now stand, "that the migration or importation of such persons as the several States shall think proper to admit, should not be prohibited till the year 1808." It was observed by some gentlemen present that this expression would extend to other persons besides slaves, which was not denied, but this did not produce any alteration of it....
Mr. Dayton (the Speaker) commenced his observations with declaring that he should not have risen on this occasion, if no allusion had been made to the proceedings in the Federal Convention which framed the Constitution of the United States, or if the representation which was given of what passed in that body, had been a perfectly correct and candid one. He expressed his surprise at what had fallen from the gentleman from Georgia (Mr. Baldwin) relatively to that part of the Constitution, which had been selected as the text of opposition to the bill under consideration, viz: "The migration or importation of such persons as any of the States now existing 'shall think proper to admit, shall not be prohibited by Congress, 'prior to the year 1808." He could only ascribe either to absolute forgetfulness, or to willful misrepresentation, the assertion of the member from Georgia, that it was understood and intended by the General Convention that the article in question should extend to the importation or introduction of citizens from foreign countries. As that gentleman and himself were the only two members of the House of Representatives who had the honor of a seat in that body, he deemed it his indispensable duty to correct the misstatement that had thus been made. He did not therefore, hesitate to say, in direct contradiction to this novel construction of the article (made as it would seem to suit the particular purposes of the opponents of the Alien bill) that the proposition itself was originally drawn up and moved in the Convention, by the deputies from South Carolina, for the express purpose of preventing Congress from interfering with the introduction of slaves into the United States, within the time specified. He recollected also, that in the discussion of its merits no question arose, or was agitated respecting the admission of foreigners but, on the contrary, that it was confined simply to slaves, and was first voted upon and carried with that word expressed in it, which was afterwards upon reconsideration changed for 'such persons,' as it now stands, upon the suggestion of one of the Deputies from Connecticut. The sole reason assigned for changing it was, that it would be better not to stain the Constitutional code with such a term, since it could be avoided by the introduction of other equally intelligible words, as had been done in the former part of the same instrument, where the same sense was conveyed by the circuitous expression of 'three fifths of all other persons.' Mr. Dayton said that at that time he was far from believing, and that indeed until the present debate arose, he had never heard, that any one member supposed that the simple change of the term would enlarge the construction of this prohibitory provision, as it was now contended for. If it could have been conceived to be really liable to such interpretation, he was convinced that it would not have been adopted, for it would then carry with it a strong injunction upon Congress to prohibit the introduction of foreigners into newly erected States immediately, and into the then existing States after the year 1808, as it undoubtedly does, that of slaves after that period....
Mr. Baldwin ... observed that he was yesterday obliged to leave the House a little before adjournment, and he had understood that, in his absence, the remarks which he had made on that point a few days ago, in Committee of the Whole, had been controverted, and that it had been done with some degree of harshness and personal disrespect. What he had before asserted was, that the clause respecting migration and importation was not considered at the time when it passed in the Convention as confined entirely to the subject of slaves. He spoke with the more confidence on this point, as there was scarcely one to which his attention had been so particularly called at the time. In making the Federal Constitution, when it was determined that it should be a Government possessing Legislative powers, the delegates from the two Southern States, of which he was one, were so fully persuaded that those powers would be used to the destruction of their property in slaves, that for some time they thought it would not be possible for them to be members of it: to that interesting state of the subject he had before alluded. In the progress of the business, other obstacles occurring, which he need not repeat, it was concluded to give to the delegates of those States the offer of preparing a clause to their own minds, to secure that species of property. He well remembered that when the clause was first prepared, it differed in two respects from the form in which it now stands. It used the word "slaves" instead of "migration", or "importation," or persons, and instead of "ten dollars," it was expressed "five percent ad valorem on their importation," which it was supposed would be about the average rate of duties under this Government. Several persons had objections to the use of the word "slaves, as Congress had hitherto avoided the use of it in their acts, and not acknowledged the existence of such a condition. It was expressly observed at the time, that making use of the form of expression as it now stands, instead of the word slaves, would make the meaning more general, and include what we now consider as included; this did not appear to be denied, but still it was preferred in its present form. He had more confidence than common in his recollection on this point, for the reasons which he had before stated. He gave it as the result of his very clear recollection. Any other member of that body was doubtless at liberty to say he did not recollect it. Still that would not diminish the confidence he felt on this occasion....[576]
In a letter to Robert Walsh November 27, 1817, Madison said:
Your letter of the 11th was duly recd, and I should have given it a less tardy answer, but for a succession of particular demands on my attention, and a wish to assist my recollections, by consulting both manuscript & printed sources of information on the subjects of your enquiry. Of these, however, I have not been able to avail myself, but very partially.
As to the intention of the framers of the Constitution in the clause relating to "the migration and importation of persons &c" the best key may perhaps be found in the case which produced it. The African trade in slaves had long been odious to most of the States, and the importation of slaves into them had been prohibited. Particular States however continued the importation, and were extremely adverse to any restriction on their power to do so. In the Convention the former States were anxious, in framing a new constitution, to insert a provision for an immediate and absolute stop to the trade. The latter were not only averse to any interference on the subject; but solemnly declared that their constituents would never accede to a constitution containing such an article. Out of this conflict grew the middle measure providing that Congress should not interfere until the year 1808; with an implication, that after that date, they might prohibit the importation of slaves into the States then existing, & previous thereto, into the States not then existing. Such was the tone of opposition in the States of S. Carolina & Georgia, & such the desire to gain their acquiescence in a prohibitory power, that on a question between the epochs of 1800 & 1808, the States of N. Hampshire, Massatts, & Connecticut, (all the eastern States in the convention); joined in the vote for the latter, influenced by the collateral motive of reconciling those particular States to the power over commerce & navigation; against which they felt, as did some other States, a very strong repugnance. The earnestness of S. Carolina & Georgia was further manifested by their insisting on the security in the V. article against any amendment to the Constitution affecting the right reserved to them, & their uniting with the small states who insisted on a like security for their equality in the Senate.
But some of the States were not only anxious for a constitutional provision against the introduction of Slaves. They had scruples against admitting the term "Slaves" into the Instrument. Hence the descriptive phrase "migration or importation of persons"; the term migration allowing those who were scrupulous of acknowledging expressly a property in human beings, to view imported persons as a species of emigrants, whilst others might apply the term to foreign malefactors sent or coming into the country. It is possible tho' not recollected, that some might have had an eye to the case of freed blacks, as well as malefactors.
But whatever may have been intended by the term "migration" or the term "persons", it is most certain, that they referred, exclusively, to a migration or importation from other countries into the U. States; and not to a removal, voluntary or involuntary, of Slaves or freemen, from one to another part of the U. States. Nothing appears or is recollected that warrants this latter intention. Nothing in the proceedings of the State conventions indicate such a construction there. Had such been in the construction it is easy to imagine the figure it would have made in many of the states, among the objections to the constitution, and among the numerous amendments to it proposed by the state conventions, not one of which amendments refers to the clause in question.... It falls within the scope of your enquiry, to state the fact, that there was a proposition in the convention, to discriminate between the old and new States, by an article in the Constitution declaring that the aggregate number of representatives from the states thereafter to be admitted, should never exceed that of the states originally adopting the Constitution. The proposition happily was rejected. The effect of such a descrimination, is sufficiently evident.[577]
Speaking about the meaning of migration, Walter Lowrie of Pennsylvania said in the United States Senate:
In the Constitution it is provided that "the migration or importation of such persons as any of the States now existing shall think proper to admit, shall not be prohibited by the Congress prior to the year 1808, but a tax," etc. In this debate it seems generally to be admitted, by gentlemen on the opposite side, that these two words are not synonomous; but what their meaning is, they are not so well agreed. One gentlemen tells us, it was intended to prevent slaves from being brought in by land; another gentleman says, it was intended to restrain Congress from interfering with emigration from Europe.
These constructions cannot both be right. The gentlemen who have preceded me on the same side, have advanced a number of pertinent arguments to settle the proper meaning of these words. I, sir, shall not repeat them. Indeed, to me, there is nothing more dry and uninteresting, than discussions to explain the meaning of single words. In the present case, I will only refer to the authority of Mr. Madison and Judge Wilson, who were both members of the Convention, and who gave their construction to these words, long before this question was agitated. Mr. Madison observes, that, to say this clause was intended to prevent emigration does not deserve an answer. And Judge Wilson says, expressly, it was intended to place the new States under the control of Congress, as to the introduction of slaves. The opinion of this latter gentleman is entitled to peculiar weight. After the Convention had labored for weeks on the subject of representation and direct taxes—when those great men were like to separate without obtaining their object, Judge Wilson submitted the provision on this subject, which now stands as a part of your Constitution. Sir, there is no man, from any part of the nation, who understood the system of our Government better than him; not even excepting Virginia, from whence the gentleman from Georgia (Mr. Walker) tells us, we have all our great men.[578]
Madison wrote on the same question that year in a letter to Monroe:
I have been truly astonished at some of the doctrines and declarations to which the Missouri question has led; and particularly so at the interpretation put on the terms "migration or importation &c." Judging from my own impressions I shd. deem it impossible that the memory of any one who was a member of the Genl. Convention, could favor an opinion that the terms did not exclusively refer to migration & importation, into the U. S. Had they been understood in that Body in the sense now put on them, it is easy to conceive the alienation they would have there created in certain States: and no one can decide better than yourself the effect they would had in the State conventions, if such a meaning had been avowed by the advocates of the Constitution. If a suspicion had existed of such a construction, it wd. at least have made a conspicuous figure among the amendments proposed to the Instrument.[579]
There was very little objection to the provision for the return of fugitive slaves. On the twenty-ninth of August, it was agreed that:
