Mr. Buchanan said that, for two or three weeks past, there had been in his possession a memorial from the Cain Quarterly Meeting of the religious Society of Friends, in the State of Pennsylvania, requesting Congress to abolish slavery and the slave trade within the District of Columbia. This memorial was not a printed form—its language was not that in established use for such documents. It did not proceed from those desperate fanatics who have been endeavoring to disturb the security and peace of society in the Southern States, by the distribution of incendiary pamphlets and papers. Far different is the truth. It emanates from a society of Christians, whose object had always been to promote peace and good-will among men, and who have been the efficient and persevering friends of humanity in every clime. To their untiring efforts, more than to those of any other denomination of Christians, we owe the progress which has been made in abolishing the African slave trade throughout the world. This memorial was their testimony against the existence of slavery. This testimony they had borne for more than a century. Of the purity of their motives, there could not be a question.

He had omitted to present this memorial at an earlier day, because he had thought that, on its presentation at the proper time, much good might be done. He had believed that, by private consultations, some resolution might be devised upon this exciting subject which would obtain the unanimous vote of the Senate. If there was one man in that body not willing to adopt a proper measure to calm the troubled spirit of the South, he did not know him. This, in his judgment, would be the best mode of accomplishing the object which we all desire to accomplish. The proper course to attain this result was, in his opinion, to refer the subject, either to a select committee, or to the Committee for the District of Columbia. They would examine it in all its bearings, they would ascertain the views and feelings of individual Senators, and he had no doubt they would be able to recommend some measure to the Senate on which they could all unite. This would have a most happy effect upon the country. He had intended, upon presenting the memorial which he had in charge, to have suggested this mode of proceeding. He regretted, therefore, he had not known that his friend from Ohio (Mr. Morris) was in possession of memorials having a similar object in view. If he had been informed of it, he should have endeavored to persuade him to wait until Monday next, when he (Mr. B.) would have been prepared to pursue the course he had indicated. But the question has now been forced upon us. No (said Mr. B.), it has not been forced upon me, because I am glad to have a suitable occasion of expressing my opinions upon the subject.

The memorial which I have in my possession is entitled to the utmost respect, from the character of the memorialists. As I entirely dissent from the opinion which they express, that we ought to abolish slavery in the District of Columbia, I feel it to be due to them, to myself, and to the Senate, respectfully, but firmly, to state the reasons why I cannot advocate their views or acquiesce in their conclusions.

If any one principle of constitutional law can, at this day, be considered as settled, it is, that Congress have no right, no power, over the question of slavery within those States where it exists. The property of the master in his slave existed in full force before the Federal Constitution was adopted. It was a subject which then belonged, as it still belongs, to the exclusive jurisdiction of the several States. These States, by the adoption of the Constitution, never yielded to the General Government any right to interfere with the question. It remains where it was previous to the establishment of our confederacy.

The Constitution has, in the clearest terms, recognized the right of property in slaves. It prohibits any State into which a slave may have fled from passing any law to discharge him from slavery, and declares that he shall be delivered up by the authorities of such State to his master. Nay, more, it makes the existence of slavery the foundation of political power, by giving to those States within which it exists representatives in Congress, not only in proportion to the whole number of free persons, but also in proportion to three-fifths of the number of slaves.

An occasion very fortunately arose in the first Congress to settle this question forever. The Society for the abolition of Slavery in Pennsylvania brought it before that Congress by a memorial which was presented on the 11th day of February, 1790. After the subject had been discussed for several days, and after solemn deliberation, the House of Representatives, in Committee of the Whole, on the 23d day of March, 1790, resolved “That Congress have no authority to interfere in the emancipation of slaves, or in the treatment of them within any of the States; it remaining with the several States alone to provide any regulations therein, which humanity and true policy may require.”

I have thought it would be proper to present this decision, which was made almost half a century ago, distinctly to the view of the American people. The language of the resolution is clear, precise, and definite. It leaves the question where the Constitution left it, and where, so far as I am concerned, it ever shall remain. The Constitution of the United States never would have been called into existence,—instead of the innumerable blessings which have flowed from our happy Union, we should have had anarchy, jealousy, and civil war among the sister Republics of which our confederacy is composed, had not the free States abandoned all control over this question. For one, whatever may be my opinions upon the abstract question of slavery, (and I am free to confess they are those of the people of Pennsylvania,) I shall never attempt to violate this fundamental compact. The Union will be dissolved, and incalculable evils will arise from its ashes, the moment any such attempt is seriously made by the free States in Congress.

What, then, are the circumstances under which these memorials are now presented? A number of fanatics, led on by foreign incendiaries, have been scattering “arrows, firebrands, and death” throughout the Southern States. The natural tendency of their publications is to produce dissatisfaction and revolt among the slaves, and to incite their wild passions to vengeance. All history, as well as the present condition of the slaves, proves that there can be no danger of the final result of a servile war. But, in the mean time, what dreadful scenes may be enacted before such an insurrection, which would spare neither age nor sex, could be suppressed! What agony of mind must be suffered, especially by the gentler sex, in consequence of these publications! Many a mother clasps her infant to her bosom when she retires to rest, under dreadful apprehensions that she may be aroused from her slumbers by the savage yells of the slaves by whom she is surrounded. These are the works of the abolitionists. That their motives may be honest I do not doubt, but their zeal is without knowledge. The history of the human race presents numerous examples of ignorant enthusiasts, the purity of whose intentions cannot be doubted, who have spread devastation and bloodshed over the face of the earth.

These fanatics, instead of benefiting the slaves who are the objects of their regard, have inflicted serious injury upon them. Self-preservation is the first law of nature. The masters, for the sake of their wives and children, for the sake of all that is near and dear to them on earth, must tighten the reins of authority over their slaves. They must thus counteract the efforts of the abolitionists. The slaves are denied many indulgences which their masters would otherwise cheerfully grant. They must be kept in such a state of bondage as effectually to prevent their rising. These are the injurious effects produced by the abolitionists upon the slave himself. Whilst, on the one hand, they render his condition miserable, by presenting to his mind vague notions of freedom never to be realized, on the other, they make it doubly miserable, by compelling the master to be severe, in order to prevent any attempts at insurrection. They thus render it impossible for the master to treat his slave according to the dictates of his heart and his feelings.

Besides, do not the abolitionists perceive that the spirit which is thus roused must protract to an indefinite period the emancipation of the slave? The necessary effect of their efforts is to render desperate those to whom the power of emancipation really belongs. I believe most conscientiously, in whatever light this subject can be viewed, that the best interests of the slave require that the question should be left, where the Constitution has left it, to the slaveholding States themselves, without foreign interference.
