The Anti-Slavery Examiner Volume II Part 2

This specification touching the soil was merely definitive and explanatory of that clause in the act of cession, "_full and absolute right_." Instead of restraining the power of Congress on _slavery_ and other subjects, it even gives it freer course; for exceptions to _parts_ of a rule, give double confirmation to those parts not embraced in the exceptions. If it was the _design_ of the proviso to restrict congressional action on the subject of _slavery_, why is the _soil alone_ specified? As legal instruments are not paragons of economy in words, might not "John Doe," out of his abundance, and without spoiling his style, have afforded an additional word--at least a hint--that slavery was _meant_, though nothing was said about it?

But again, Maryland and Virginia, in their acts of cession, declare them to be made "in pursuance of" that clause of the const.i.tution which gives to Congress "exclusive legislation in all cases whatsoever" over the ten miles square--thus, instead of _restricting_ that clause, both States _confirm_ it. Now, their acts of cession either accorded with that clause of the const.i.tution, or they conflicted with it. If they conflicted with it, _accepting_ the cessions was a violation of the const.i.tution. The fact that Congress accepted the cessions, proves that in its views their _terms_ did not conflict with its const.i.tutional grant of power. The inquiry whether these acts of cession were consistent or inconsistent with the United Status' const.i.tution, is totally irrelevant to the question at issue. What with the CONSt.i.tUTION?

That is the question. Not, what with Virginia, or Maryland, or--equally to the point--John Bull! If Maryland and Virginia had been the authorized interpreters of the const.i.tution for the Union, these acts of cession could hardly have been more magnified than they have been recently by the southern delegation in Congress. A true understanding of the const.i.tution can be had, forsooth, only by holding it up in the light of Maryland and Virginia legislation!

We are told, again, that those States would not have ceded the District if they had supposed the const.i.tution gave Congress power to abolish slavery in it.

This comes with an ill grace from Maryland and Virginia. They _knew_ the const.i.tution. They were parties to it. They had sifted it, clause by clause, in their State conventions. They had weighed its words in the balance--they had tested them as by fire; and, finally, after long pondering, they adopted the const.i.tution. And _afterward_, self-moved, they ceded the ten miles square, and declared the cession made "in pursuance of" that oft-cited clause, "Congress shall have power to exercise exclusive legislation in all cases whatsoever over such District." And now verily "they would not have ceded if they had _supposed_!" &c. Cede it they _did_, and in "full and absolute right both of soil and persons." Congress accepted the cession--state power over the District ceased, and congressional power over it commenced,--and now, the sole question to be settled is, the _amount of power over the District lodged in Congress by the const.i.tution_. The const.i.tution--THE CONSt.i.tUTION--that is the point. Maryland and Virginia "suppositions" must be potent suppositions to abrogate a clause of the United States' Const.i.tution! That clause either gives Congress power to abolish slavery in the District, or it does _not_--and that point is to be settled, not by state "suppositions," nor state usages, nor state legislation, but _by the terms of the clause themselves_.

Southern members of Congress, in the recent discussions, have conceded the power of a contingent abolition in the District, by suspending it upon the _consent_ of the people. Such a doctrine from _declaimers_ like Messrs. Alford, of Georgia, and Walker, of Mississippi, would excite no surprise; but that it should be honored with the endors.e.m.e.nt of such men as Mr. Rives and Mr. Calhoun, is quite unaccountable. Are attributes of sovereignty mere creatures of contingency? Is delegated authority mere conditional permission? Is a const.i.tutional power to be exercised by those who hold it, only by popular sufferance? Must it lie helpless at the pool of public sentiment, waiting the gracious troubling of its waters? Is it a lifeless corpse, save only when popular "consent" deigns to puff breath into its nostrils? Besides, if the consent of the people of the District be necessary, the consent of the _whole_ people must be had--not that of a majority, however large. Majorities, to be authoritative, must be _legal_--and a legal majority without legislative power, or right of representation, or even the electoral franchise, would be truly an anomaly! In the District of Columbia, such a thing as a majority in a legal sense is unknown to law. To talk of the power of a majority, or the will of a majority there, is mere mouthing. A majority?

Then it has an authoritative will, and an organ to make it known, and an executive to carry it into effect--Where are they? We repeat it--if the consent of the people of the District be necessary, the consent of _every one_ is necessary--and _universal_ consent will come only with the Greek Kalends and a "perpetual motion." A single individual might thus perpetuate slavery in defiance of the expressed will of a whole people. The most common form of this fallacy is given by Mr. Wise, of Virginia, in his speech, February 16, 1835, in which he denied the power of Congress to abolish slavery in the District, unless the inhabitants owning slaves pet.i.tioned for it!! Southern members of Congress at the present session (1837-8) ring changes almost daily upon the same fallacy. What! pray Congress _to use_ a power which it _has not_? "It is required of a man according to what he _hath_," saith the Scripture. I commend Mr. Wise to Paul for his ethics. Would that he had got his _logic_ of him! If Congress does not possess the power, why taunt it with its weakness, by asking its exercise? Pet.i.tioning, according to Mr.

Wise, is, in matters of legislation, omnipotence itself; the very _source_ of all const.i.tutional power; for, _asking_ Congress to do what it _cannot_ do, gives it the power!--to pray the exercise of a power that is _not, creates_ it! A beautiful theory! Let us work it both ways.

If to pet.i.tion for the exercise of a power that is _not_, creates it--to pet.i.tion against the exercise of a power that _is_, annihilates it. As southern gentlemen are partial to summary processes, pray, sirs, try the virtue of your own recipe on "exclusive legislation in all cases whatsoever;" a better subject for experiment and test of the prescription could not be had. But if the pet.i.tions of the citizens of the District give Congress the _right_ to abolish slavery, they impose the _duty_; if they confer const.i.tutional _authority_, they create const.i.tutional _obligation_. If Congress _may_ abolish because of an expression of their will, it _must_ abolish at the bidding of that will.

If the people of the District are a _source of power_ to Congress, their _expressed will_ has the force of a const.i.tutional provision, and has the same binding power upon the National Legislature. To make Congress dependent on the District for authority, is to make it a _subject_ of its authority, restraining the exercise of its own discretion, and sinking it into a mere organ of the District's will. We proceed to another objection.

"_The southern states would not have ratified the const.i.tution, if they had supposed that it gave this power_." It is a sufficient answer to this objection, that the northern states would not have ratified it, if they had supposed that it _withheld_ the power. If "suppositions" are to take the place of the const.i.tution--coming from both sides, they neutralize each other. To argue a const.i.tutional question by _guessing_ at the "suppositions" that might have been made by the parties to it would find small favor in a court of law. But even a desperate s.h.i.+ft is some eas.e.m.e.nt when sorely pushed. If this question is to be settled by "suppositions," suppositions shall be forthcoming, and that without stint.

First, then, I affirm that the North ratified the const.i.tution, "supposing" that slavery had begun to wax old, and would speedily vanish away, and especially that the abolition of the slave trade, which by the const.i.tution was to be surrendered to Congress after twenty years, would plunge it headlong.

Would the North have adopted the const.i.tution, giving three-fifths of the "slave property" a representation, if it had "supposed" that the slaves would have increased from half a million to two millions and a half by 1838--and that the census of 1840 would give to the slave states thirty representatives of "slave property?"

If they had "supposed" that this representation would have controlled the legislation of the government, and carried against the North every question vital to its interests, would Hamilton, Franklin, Sherman, Gerry, Livingston, Langdon, and Rufus King have been such madmen, as to sign the const.i.tution, and the Northern States such suicides as to ratify it? Every self-preserving instinct would have shrieked at such an infatuate immolation. At the adoption of the United States const.i.tution, slavery was regarded as a fast waning system. This conviction was universal. Was.h.i.+ngton, Jefferson, Henry, Grayson, Tucker, Madison, Wythe, Pendleton, Lee, Blair, Mason, Page, Parker, Randolph, Iredell, Spaight, Ramsey, Pinkney, Martin, McHenry, Chase, and nearly all the ill.u.s.trious names south of the Potomac, proclaimed it before the sun. A reason urged in the convention that formed the United States'

const.i.tution, why the word slave should not be used in it, was, _that when slavery should cease_ there might remain upon the National Charter no record that it had ever been. (See speech of Mr. Burrill, of R.I., on the Missouri question.)

I now proceed to show by testimony, that at the date of the United States' const.i.tution, and for several years before and after that period, slavery was rapidly on the wane; that the American Revolution with the great events preceding, accompanying, and following it, had wrought an immense and almost universal change in the public sentiment of the nation on the subject, powerfully impelling it toward the entire abolition of the system--and that it was the _general belief_ that measures for its abolition throughout the Union, would be commenced by the States generally before the lapse of many years. A great ma.s.s of testimony establis.h.i.+ng this position might be presented, but narrow s.p.a.ce, and the importance of speedy publication, counsel brevity. Let the following proofs suffice. First, a few dates as points of observation.

In 1757, Commissioners from seven colonies met at Albany, resolved upon a Union and proposed a plan of general government. In 1765, delegates from nine colonies met at New York and sent forth a bill of rights. The first _general_ Congress met in 1774. The first Congress of the _thirteen_ colonies met in 1775. The revolutionary war commenced in '75.

Independence was declared in '76. The articles of confederation were adopted by the thirteen states in '77 and '78. Independence acknowledged in '83. The convention for forming the U.S. const.i.tution was held in '87, the state conventions for considering it in '87 and '88. The first Congress under the const.i.tution in '89.

Dr. Rush, of Pennsylvania, one of the signers of the Declaration of Independence, in a letter to Granville Sharpe, May 1, 1773, says: "A spirit of humanity and religion begins to awaken in several of the colonies in favor of the poor negroes. Great events have been brought about by small beginnings. _Anthony Benezet stood alone a few years_ _ago in opposing negro slavery in Philadelphia_, and NOW THREE-FOURTHS OF THE PROVINCE AS WELL AS OF THE CITY CRY OUT AGAINST IT."--[Stuart's Life of Granville Sharpe, p. 21.]

In the preamble to the act prohibiting the importation of slaves into Rhode Island, June, 1774, is the following: "Whereas the inhabitants of America are generally engaged in the preservation of their own rights and liberties, among which that of personal freedom must be considered the greatest, and as those who are desirous of enjoying all the advantages of liberty themselves, _should be willing to extend personal liberty to others_, therefore," &c.

October 20, 1774, the Continental Congress pa.s.sed the following: "We, for ourselves and the inhabitants of the several colonies whom we represent, _firmly agree and a.s.sociate under the sacred ties of virtue, honor, and love of our country_, as follows:"

"2d Article. _We will neither import nor purchase any slaves imported_ after the first day of December next, after which time we will _wholly discontinue_ the slave trade, and we will neither be concerned in it ourselves, nor will we hire our vessels nor _sell our commodities or manufactures_ to those who are concerned in it."

The Continental Congress, in 1775, setting forth the causes and the necessity for taking up arms, say: "_If it were possible_ for men who exercise their reason to believe that the divine Author of our existence intended a part of the human race _to hold an absolute property in_, and _unbounded power over others_," &c.

In 1776, Dr. Hopkins, then at the head of New England divines, in "An Address to the owners of negro slaves in the American colonies,"

says: "The conviction of the unjustifiableness of this practice (slavery) has been _increasing_, and _greatly spreading of late_, and _many_ who have had slaves, have found themselves so unable to justify their own conduct in holding them in bondage, as to be induced to _set them at liberty_. * * * * * Slavery is _in every instance_, wrong, unrighteous, and oppressive--a very great and crying sin--_there being nothing of the kind equal to it on the face of the earth_."

The same year the American Congress issued a solemn MANIFESTO to the world. These were its first words: "We hold these truths to be self-evident, that _all_ men are created equal, that they are endowed by their Creator with certain inalienable rights; that among these are life, liberty, and the pursuit of happiness." _Once_, these were words of power; _now_, "a rhetorical flourish."

The Virginia Gazette of March 19, 1767, in an essay on slavery says: "_There cannot be in nature, there is not in all history, an instance in which every right of man is more flagrantly violated_. Enough I hope has been effected to prove that slavery is a violation of justice and religion."

The celebrated Patrick Henry of Virginia, in a letter, Jan. 18, 1773, to Robert Pleasants, afterwards president of the Virginia Abolition Society, says: "Believe me, I shall honor the Quakers for their n.o.ble efforts to abolish slavery. It is a debt we owe to the purity of our religion to show that it is at variance with that law that warrants slavery. I exhort you to persevere in so worthy a resolution."

The Pennsylvania Chronicle of Nov. 21, 1768, says: "Let every black that shall henceforth be born amongst us be deemed free. One step farther would be to emanc.i.p.ate the whole race, restoring that liberty we have so long unjustly detained from them. Till some step of this kind be taken we shall justly be the derision of the whole world."

In 1779, the Continental Congress ordered a pamphlet to be published, ent.i.tled, "Observations on the American Revolution," from which the following is an extract: "The great principle (of government) is and ever will remain in force, _that men are by Nature free_; and so long as we have any idea of divine _justice_, we must a.s.sociate that of _human freedom_. It is _conceded on all hands, that the right to be free_ CAN NEVER BE ALIENATED."

Extract from the Pennsylvania act for the abolition of slavery, pa.s.sed March 1, 1780: * * * "We conceive that it is our duty, and we rejoice that it is in our power, to extend a portion of that freedom to others which has been extended to us. Weaned by a long course of experience from those narrow prejudices and partialities we had imbibed, we find our hearts enlarged with kindness and benevolence towards men of all conditions and nations: * * * Therefore be it enacted, that no child born hereafter be a slave," &c.

Jefferson, in his Notes on Virginia, written just before the close of the Revolutionary War, says: "I think a change already perceptible since the origin of the present revolution. The spirit of the master is abating, that of the slave is rising from the dust, his condition mollifying, _and the way I hope preparing, under the auspices of heaven_, FOR A TOTAL EMANc.i.p.aTION."

In a letter to Dr. Price, of London, who had just published a pamphlet in favor of the abolition of slavery, Mr. Jefferson, then minister at Paris, (August 7, 1785,) says: "From the mouth to the head of the Chesapeake, _the bulk of the people will approve of your pamphlet in theory_, and it will find a respectable minority ready to _adopt it in practice_--a minority which, for weight and worth of character, _preponderates against the greater number_." Speaking of Virginia, he says: "This is the next state to which we may turn our eyes for the interesting spectacle of justice in conflict with avarice and oppression,--a conflict in which the SACRED SIDE IS GAINING DAILY RECRUITS. Be not, therefore, discouraged--what you have written will do a _great deal of good_; and could you still trouble yourself with our welfare, no man is more able to give aid to the laboring side. The College of William and Mary, since the remodelling of its plan, is the place where are collected together all the young men of Virginia, under preparation for public life. They are there under the direction (most of them) of a Mr. Wythe, one of the most virtuous of characters, and _whose sentiments on the subject of slavery are unequivocal_. I am satisfied, if you could resolve to address an exhortation to those young men with all that eloquence of which you are master, that _its influence on the future decision of this important question would be great, perhaps decisive_. Thus. you see, that so far from thinking you have cause to repent of what you have done, _I wish you to do more, and I wish it on an a.s.surance of its effect_."--Jefferson's Posthumous Works, vol. 1, p. 268.

In 1786, John Jay drafted and signed a pet.i.tion to the Legislature of New York, on the subject of slavery, beginning with these words: "Your memorialists being deeply affected by the situation of those, who, although, FREE BY THE LAWS OF G.o.d, are held in slavery by the laws of the State," &c. This memorial bore also the signatures of the celebrated Alexander Hamilton; Robert R. Livingston, afterwards Secretary of Foreign Affairs of the United States, and Chancellor of the State of New York; James Duane, Mayor of the City of New York, and many others of the most eminent individuals in the State.

In the preamble of an instrument, by which Mr. Jay emanc.i.p.ated a slave in 1784, is the following pa.s.sage:

"Whereas, the children of men are by nature equally free, and cannot, without injustice, be either reduced to or HELD in slavery."

In his letter while Minister at Spain, in 1786, he says, speaking of the abolition of slavery: "Till America comes into this measure, her prayers to heaven will be IMPIOUS. I believe G.o.d governs the world; and I believe it to be a maxim in his, as in our court, that those who ask for equity _ought to do it_."

In 1785, the New York Manumission Society was formed. John Jay was chosen its first President, and held the office five years. Alexander Hamilton was its second President, and after holding the office one year, resigned upon his removal to Philadelphia as Secretary of the United States' Treasury. In 1787, the Pennsylvania Abolition Society was formed. Benjamin Franklin, warm from the discussions of the convention that formed the U.S. const.i.tution, was chosen President, and Benjamin Rush Secretary--both signers of the Declaration of Independence. In 1789, the Maryland Abolition Society was formed. Among its officers were Samuel Chase, Judge of the U.S. Supreme Court, and Luther Martin, a member of the convention that formed the U.S. const.i.tution. In 1790, the Connecticut Abolition Society was formed. The first President was Rev.

Dr. Stiles, President of Yale College, and the Secretary, Simeon Baldwin, (late Judge Baldwin of New Haven.) In 1791, this Society sent a memorial to Congress, from which the following is an extract:

"From a sober conviction of the unrighteousness of slavery, your pet.i.tioners have long beheld, with grief, our fellow men doomed to perpetual bondage, in a country which boasts of her freedom. Your pet.i.tioners were led, by motives, we conceive, of general philanthropy, to a.s.sociate ourselves for the protection and a.s.sistance of this unfortunate part of our fellow men; and, though this Society has been _lately_ established, it has now become _generally extensive_ through this state, and, we fully believe, _embraces, on this subject, the sentiments of a large majority of its citizens_."

The same year the Virginia Abolition Society was formed. This Society, and the Maryland Society, had auxiliaries in different parts of those States. Both societies sent up memorials to Congress. The memorial of the Virginia Society is headed--"The memorial of the _Virginia Society_, for promoting the Abolition of Slavery," &c. The following is an extract:

"Your memorialists, fully believing that slavery is not only an odious degradation, but an _outrageous violation of one of the most essential rights of human nature, and utterly repugnant to the precepts of the gospel_," &c.

About the same time a Society was formed in New-Jersey. It had an acting committee of five members in each county in the State. The following is an extract from the preamble to its const.i.tution:

"It is our boast, that we live under a government, wherein _life, liberty_, and the _pursuit of happiness_, are recognized as the universal rights of men. We _abhor that inconsistent, illiberal, and interested policy, which withholds those rights from an unfortunate and degraded cla.s.s of our fellow creatures_."

Among other distinguished individuals who were efficient officers of these Abolition Societies, and delegates from their respective state societies, at the annual meetings of the American convention for promoting the abolition of slavery, were Hon. Uriah Tracy, United States' Senator, from Connecticut; Hon. Zephaniah Swift, Chief Justice of the same State; Hon. Cesar A. Rodney, Attorney General of the United States; Hon. James A. Bayard, United States' Senator, from Delaware; Governor Bloomfield, of New-Jersey; Hon. Wm. Rawle, the late venerable head of the Philadelphia bar; Dr. Caspar Wistar, of Philadelphia; Messrs. Foster and Tillinghast, of Rhode Island; Messrs. Ridgely, Buchanan, and Wilkinson, of Maryland; and Messrs. Pleasants, McLean, and Anthony, of Virginia.

In July, 1787, the old Congress pa.s.sed the celebrated ordinance abolis.h.i.+ng slavery in the northwestern territory, and declaring that it should never thereafter exist there. This ordinance was pa.s.sed while the convention that formed the United States' const.i.tution was in session.

At the first session of Congress under the const.i.tution, this ordinance was ratified by a special act. Was.h.i.+ngton, fresh from the discussions of the convention, in which _more than forty days had been spent in adjusting the question of slavery, gave it his approval_. The act pa.s.sed with only one dissenting voice, (that of Mr. Yates, of New York,) _the South equally with the North avowing the fitness and expediency of the measure on general considerations, and indicating thus early the line of national policy, to be pursued by the United States' Government on the subject of slavery_.

In the debates in the North Carolina Convention, Mr. Iredell, afterward a Judge of the United States' Supreme Court, said, "_When the entire abolition of slavery takes place_, it will be an event which must be pleasing to every generous mind and every friend of human nature." Mr.

Galloway said, "I wish to see this abominable trade put an end to. I apprehend the clause (touching the slave trade) means _to bring forward manumission_." Luther Martin, of Maryland, a member of the convention that formed the United States' Const.i.tution, said, "We ought to authorize the General Government to make such regulations as shall be thought most advantageous for _the gradual abolition of slavery_, and the _emanc.i.p.ation of the slaves_ which are already in the States." Judge Wilson, of Pennsylvania, one of the framers of the const.i.tution, said, in the Pennsylvania convention of '87, [Deb. Pa. Con. p. 303, 156:] "I consider this (the clause relative to the slave trade) as laying the foundation for _banis.h.i.+ng slavery out of this country_. It will produce the same kind of gradual change which was produced in Pennsylvania; the new States which are to be formed will be under the control of Congress in this particular, and _slaves will never be introduced_ among them. It presents us with the pleasing prospect that the rights of mankind will be acknowledged and established _throughout the Union_. Yet the lapse of a few years, and Congress will have power to _exterminate slavery_ within our borders." In the Virginia convention of '87, Mr. Mason, author of the Virginia const.i.tution, said, "The augmentation of slaves weakens the States, and such a trade is _diabolical_ in itself, and disgraceful to mankind. As much as I value a union of all the States, I would not admit the Southern States, (i.e., South Carolina and Georgia,) into the union, _unless they agree to a discontinuance of this disgraceful trade_." Mr. Tyler opposed with great power the clause prohibiting the abolition of the slave trade till 1808, and said, "My earnest desire is, that it shall be handed down to posterity that I oppose this wicked clause." Mr. Johnson said, "The principle of emanc.i.p.ation _has begun since the revolution. Let us do what we will, it will come round_."--[Deb. Va. Con. p. 463.] Patrick Henry, arguing the power of Congress under the United States' const.i.tution to abolish slavery in the States, said, in the same convention, "Another thing will contribute to bring this event (the abolition of slavery) about. Slavery is _detested_. We feel its fatal effects; we deplore it with all the pity of humanity." Governor Randolph said: "They insist that the _abolition of slavery will result from this Const.i.tution_. I hope that there is no one here, who will advance _an objection so dishonorable_ to Virginia--I hope that at the moment they are securing the rights of their citizens, an objection will not be started, that those unfortunate men now held in bondage, _by the operation of the general government_ may be made free!" [_Deb. Va. Con._ p. 421.] In the Ma.s.s. Con. of '88, Judge Dawes said, "Although slavery is not smitten by an apoplexy, yet _it has received a mortal wound_, and will die of consumption."--[_Deb.

Ma.s.s. Con._ p. 60.] General Heath said that, "Slavery was confined to the States _now existing_, it _could not be extended_. By their ordinance, Congress had declared that the new States should be republican States, _and have no slavery_."--p. 147.

In the debate, in the first Congress, February 11th and 12th, 1789, on the pet.i.tions of the Society of Friends, and the Pennsylvania Abolition Society, Mr. Parker, of Virginia, said, "I cannot help expressing the pleasure I feel in finding _so considerable a part_ of the community attending to matters of such a momentous concern to the _future prosperity_ and happiness of the people of America. I think it my duty, as a citizen of the Union, to _espouse their cause_."

Mr. Page, of Virginia, (afterwards Governor)--"Was _in favor_ of the commitment: he hoped that the designs of the respectable memorialists would not be stopped at the threshold, in order to preclude a fair discussion of the prayer of the memorial. He placed himself in the case of a slave, and said, that on hearing that Congress had refused to listen to the decent suggestions of the respectable part of the community, he should infer, that the general government, _from which was expected great good would result to_ EVERY CLa.s.s _of citizens_, had shut their ears against the voice of humanity, and he should despair of any alleviation of the miseries he and his posterity had in prospect; if any thing could induce him to rebel, it must be a stroke like this, impressing on his mind all the horrors of despair. But if he was told, that application was made in his behalf, and that Congress were willing to hear what could be urged in favor of discouraging the practice of importing his fellow-wretches, he would trust in their justice and humanity, and _wait the decision patiently_."

Mr. Scott of Pennsylvania: "I cannot, for my part, conceive how any person _can be said to acquire a property in another. I do not know how far I might go, if I was one of the judges of the United States, and those people were to come before me and claim their emanc.i.p.ation, but I am sure I would go as far as I could_."

Mr. Burke, of South Carolina, said, "He _saw the disposition of the House_, and he feared it would be referred to a committee, maugre all their opposition."

Mr. Baldwin of Georgia said that the clause in the U.S. Const.i.tution relating to direct taxes "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 EMANc.i.p.aTION."

Mr. Smith of South Carolina, said, "That on entering into this government, they (South Carolina and Georgia) apprehended that the other states, * * * _would, from motives of humanity and benevolence, be led to vote for a general emanc.i.p.ation_."
