The abolition societies in the United States have in various ways manifested their opposition to colonization in Africa, and many of their members have assailed the motives and conduct of the friends of the colonization society. Insisting upon immediate abolition as the only proper course to be pursued on the subject of slavery, they have poured in their petitions to congress, session after session, asking for the abolition of slavery in the District of Columbia. Mr. Clay, it will be seen in this speech, thinks that their petitions ought to have been received by congress and reported upon by a committee, instead of being laid upon the table, without further notice, as has been the practice in one or both houses of congress. Residing, as Mr. Clay does, in a slave-holding state, and from his long experience and knowledge of the subject on which he has bestowed much reflection, this speech must ever be read with interest, and regarded as the views of a philanthropist and statesman, even by those who may not accord with him in his opinions on this very exciting topic.]

I HAVE received, Mr. President, a petition to the senate and house of representatives of the United States, which I wish to present to the senate. It is signed by several hundred inhabitants of the District of Columbia, and chiefly of the city of Washington. Among them I recognize the name of the highly esteemed mayor of the city, and other respectable names, some of which are personally and well known to me. They express their regret that the subject of the abolition of slavery within the District of Columbia continues to be pressed upon the consideration of congress by inconsiderate and misguided individuals in other parts of the United States. They state, that they do not desire the abolition of slavery within the district, even if congress possess the very questionable power of abolishing it, without the consent of the people whose interests would be immediately and directly affected by the measure; that it is a question solely between the people ofthe district and their only constitutional legislature, purely municipal, and one in which no exterior influence or interest can justly interfere; that if, at any future period, the people of this district should desire the abolition of slavery within it, they will doubtless make their wishes known, when it will be time enough to take the matter into consideration; that they do not, on this occasion, present themselves to congress because they are slaveholders; many of them are not; some of them are conscientiously opposed to slavery; but they appear because they justly respect the rights of those who own that description of property, and because they entertain a deep conviction that the continued agitation of the question by those who have no right to interfere with it, has an injurious influence on the peace and tranquillity of the community, and upon the well-being and happiness of those who are held in subjection; they finally protest as well against the unauthorized intervention of which they complain, as against any legislation on the part of congress in compliance therewith. But as I wish these respectable petitioners to be themselves heard, I request that their petition may be read. [It was read accordingly, and Mr. Clay proceeded.] I am informed by the committee which requested me to offer this petition, and believe, that it expresses the almost unanimous sentiments of the people of the District of Columbia.

The performance of this service affords me a legitimate opportunity, of which, with the permission of the senate, I mean now to avail myself, to say something, not only on the particular objects of the petition, but upon the great and interesting subject with which it is intimately associated.

It is well known to the senate, that I have thought that the most judicious course with abolition petitions has not been of late pursued by congress. I have believed that it would have been wisest to receive and refer them, without opposition, and report against their object in a calm, and dispassionate, and argumentative appeal to the good sense of the whole community. It has been supposed, however, by a majority of congress, that it was most expedient either not to receive the petitions at all, or, if formally received, not to act definitively upon them. There is no substantial difference between these opposite opinions, since both look to an absolute rejection of the prayer of the petitioners. But there is a great difference in the form of proceeding; and, Mr. President, some experience in the conduct of human affairs has taught me to believe, that a neglect to observe established forms is often attended with more mischievous consequences than the infliction of a positive injury. We all know that, even in private life, a violation of the existing usages and ceremonies of society cannot take place without serious prejudice. I fear, sir, that the abolitionists have acquired a considerable apparent force by blendingwith the object which they have in view a collateral and totally different question, arising out of an alleged violation of the right of petition. I know full well, and take great pleasure in testifying, that nothing was remoter from the intention of the majority of the senate, from which I differed, than to violate the right of petition in any case in which, according to its judgment, that right could be constitutionally exercised, or where the object of the petition could be safely or properly granted. Still it must be owned that the abolitionists have seized hold of the fact of the treatment which their petitions have received in congress, and made injurious impressions upon the minds of a large portion of the community. This, I think, might have been avoided by the course which I should have been glad to see pursued.

And I desire now, Mr. President, to advert to some of those topics which I think might have been usefully embodied in a report by a committee of the senate, and which, I am persuaded, would have checked the progress, if it had not altogether arrested the efforts of abolition. I am sensible, sir, that this work would have been accomplished with much greater ability and with much happier effect, under the auspices of a committee, than it can be by me. But, anxious as I always am to contribute whatever is in my power to the harmony, concord, and happiness of this great people, I feel myself irresistibly impelled to do whatever is in my power, incompetent as I feel myself to be, to dissuade the public from continuing to agitate a subject fraught with the most direful consequences.

There are three classes of persons opposed, or apparently opposed, to the continued existence of slavery in the United States. The first are those, who, from sentiments of philanthropy and humanity, are conscientiously opposed to the existence of slavery, but who are no less opposed, at the same time, to any disturbance of the peace and tranquillity of the union, or the infringement of the powers of the states composing the confederacy. In this class may be comprehended that peaceful and exemplary society of ‘Friends,’ one of whose established maxims is, an abhorrence of war in all its forms, and the cultivation of peace and good-will amongst mankind. The next class consists of apparent abolitionists; that is, those who, having been persuaded that the right of petition has been violated by congress, coöperate with the abolitionists for the sole purpose of asserting and vindicating that right. And the third class are the real ultra abolitionists, who are resolved to persevere in the pursuit of their object at all hazards, and without regard to any consequences, however calamitous they may be. With them the rights of property are nothing; the deficiency of the powers of the general government is nothing; the acknowledged and incontestable powers of the states are nothing; civil war, a dissolution of the union, and the overthrow of agovernment in which are concentrated the fondest hopes of the civilized world, are nothing, A single idea has taken possession of their minds, and onward they pursue it, overlooking all barriers, reckless and regardless of all consequences. With this class, the immediate abolition of slavery in the District of Columbia, and in the territory of Florida, the prohibition of the removal of slaves from state to state, and the refusal to admit any new state, comprising within its limits the institution of domestic slavery, are but so many means conducing to the accomplishment of the ultimate but perilous end at which they avowedly and boldly aim; are but so many short stages in the long and bloody road to the distant goal at which they would finally arrive. Their purpose is abolition, universal abolition; peaceably if it can, forcibly if it must be. Their object is no longer concealed by the thinnest veil; it is avowed and proclaimed. Utterly destitute of constitutional or other rightful power, living in totally distinct communities, as alien to the communities in which the subject on which they would operate resides, so far as concerns political power over that subject, as if they lived in Africa or Asia, they nevertheless promulgate to the world their purpose to be, to manumit forthwith, and without compensation, and without moral preparation, three millions of negro slaves, under jurisdictions altogether separated from those under which they live. I have said, that immediate abolition of slavery in the District of Columbia and the territory of Florida, and the exclusion of new states, were only means towards the attainment of a much more important end. Unfortunately they are not the only means. Another, and much more lamentable one is that which this class is endeavoring to employ, of arraying one portion against another portion of the union. With that view, in all their leading prints and publications, the alleged horrors of slavery are depicted in the most glowing and exaggerated colors, to excite the imaginations and stimulate the rage of the people in the free states, against the people in the slave states. The slaveholder is held up and represented as the most atrocious of human beings. Advertisements of fugitive slaves and of slaves to be sold, are carefully collected and blazoned forth, to infuse a spirit of detestation and hatred against one entire and the largest section of the union. And, like a notorious agitator upon another theatre, they would hunt down and proscribe from the pale of civilized society, the inhabitants of that entire section. Allow me, Mr. President, to say, that whilst I recognise in the justly wounded feelings of the minister of the United States at the court of St. James, much to excuse the notice which he was provoked to take of that agitator, in my humble opinion, he would better have consulted the dignity of his station and of his country in treating him with contemptuous silence. He would exclude us from European society—he who himself can only obtain a contrabandadmission, and is received with scornful repugnance into it! If he be no more desirous of our society than we are of his, he may rest assured that a state of eternal non-intercourse will exist between us. Yes, sir, I think the American minister would have best pursued the dictates of true dignity by regarding the language of the member of the British house of commons as the malignant ravings of the plunderer of his own country, and the libeller of a foreign and kindred people.

But the means to which I have already adverted are not the only ones which this third class of ultra-abolitionists are employing to effect their ultimate end. They began their operations by professing to employ only persuasive means in appealing to the humanity, and enlightening the understandings, of the slaveholding portion of the union. If there were some kindness in this avowed motive, it must be acknowledged that there was rather a presumptuous display also of an assumed superiority in intelligence and knowledge. For some time they continued to make these appeals to our duty and our interest; but impatient with the slow influence of their logic upon our stupid minds, they recently resolved to change their system of action. To the agency of their powers of persuasion, they now propose to substitute the powers of the ballot-box; and he must be blind to what is passing before us, who does not perceive that the inevitable tendency of their proceedings is, if these should be found insufficient, to invoke, finally, the more potent powers of the bayonet.

Mr. President, it is at this alarming stage of the proceedings of the ultra-abolitionists, that I would seriously invite every considerate man in the country solemnly to pause, and deliberately to reflect, not merely on our existing posture, but upon that dreadful precipice down which they would hurry us. It is because these ultra-abolitionists have ceased to employ the instruments of reason and persuasion, have made their cause political, and have appealed to the ballot-box, that I am induced, upon this occasion, to address you.

There have been three epochs in the history of our country, at which the spirit of abolition displayed itself. The first was immediately after the formation of the present federal government. When the constitution was about going into operation, its powers were not well understood by the community at large, and remained to be accurately interpreted and defined. At that period numerous abolition societies were formed, comprising not merely the society of Friends, but many other good men. Petitions were presented to congress, praying for the abolition of slavery. They were received without serious opposition, referred, and reported upon by a committee. The report stated, that the general government had no power to abolish slavery, as it existed in the several states, and that these states themselves had exclusive jurisdiction over the subject.The report was generally acquiesced in, and satisfaction and tranquillity ensued; the abolition societies thereafter limiting their exertions, in respect to the black population, to offices of humanity within the scope of existing laws.

The next period when the subject of slavery, and abolition incidentally, was brought into notice and discussion, was that on the memorable occasion of the admission of the state of Missouri into the union. The struggle was long, strenuous, and fearful. It is too recent to make it necessary to do more than merely advert to it, and to say, that it was finally composed by one of those compromises characteristic of our institutions, and of which the constitution itself is the most signal instance.
