The following memorial was presented and read:

"To the Senate and House of Representatives of the United States: The memorial of the Pennsylvania Society for promoting the abolition of slavery, the relief of free negroes unlawfully held in bondage, and the improvement of the condition of the African race, respectfully showeth: That from a regard for the happiness of mankind, an association was formed several years since in this State, by a number of her citizens, of various religious denominations, for promoting the abolition of slavery, and for the relief of those unlawfully held in bondage. A just and acute conception of the true principles of liberty, as it spread through the land, produced accessions to their numbers, many friends to their cause, and a legislative cooperation with their views, which, by the blessing of Divine Providence, have been successfully directed to the relieving from bondage a large number of their fellow creatures of the African race. They have also the satisfaction to observe, that, in consequence of that spirit of philanthropy and genuine liberty which is generally diffusing its beneficial influence, similar institutions are forming at home and abroad. That mankind are all formed by the same Almighty Being, alike objects of his care, and equally designed for the enjoyment of happiness, the Christian religion teaches us to believe, and the political creed of Americans fully coincides with the position. Your memorialists, particularly engaged in attending to the distresses arising from slavery, believe it their indispensable duty to present this subject to your notice. They have observed with real satisfaction, that many important and salutary powers are vested in you for 'promoting the welfare and securing the blessings of liberty to the people of the United States;' and as they conceive, that these blessings ought rightfully to be administered without distinction of color, to all descriptions of people, so they indulge themselves in the pleasing expectation, that nothing which can be done for the relief of the unhappy objects of their care, will be either omitted or delayed. From a persuasion that equal liberty was originally the portion, and is still the birth-right of all men, and influenced by the strong ties of humanity and the principles of their institution, your memorialists conceived themselves bound to use all justifiable endeavors to loosen the bands of slavery, and promote a general enjoyment of the blessings of freedom. Under these impressions, they earnestly entreat your serious attention to the subject of slavery; that you will be pleased to countenance the restoration of liberty to those unhappy men, who alone, in this land of freedom, are degraded into perpetual bondage, and who, amidst the general joy of surrounding freemen, are groaning in servile subjection; that you will devise means for removing this inconsistency from the character of the American people; that you will promote mercy and justice towards this distressed race, and that you will step to the very verge of the power vested in you, for discouraging every species of traffic in the persons of our fellow-men.

"PHILADELPHIA, February 3, 1790."

Mr. HARTLEY (of Penn.) then called up the memorial presented yesterday, from the annual meeting of Friends at Philadelphia, for a second reading; whereupon the same was read a second time, and moved to be committed.

Mr. TUCKER (of S.C.) was sorry the petition had a second reading, as he conceived it contained an unconstitutional request, and from that consideration he wished it thrown aside. He feared the commitment of it would be a very alarming circumstance to the Southern States; for if the object was to engage Congress in an unconstitutional measure, it would be considered as an interference with their rights, the people would become very uneasy under the government, and lament that they ever put additional powers into their hands. He was surprised to see another memorial on the same subject, and that signed by a man who ought to have known the constitution better. He thought it a mischievous attempt, as it respected the persons in whose favor it was intended. It would buoy them up with hopes, without a foundation, and as they could not reason on the subject, as more enlightened men would, they might be led to do what they would be punished for, and the owners of them, in their own defence, would be compelled to exercise over them a severity they were not accustomed to. Do these men expect a general emancipation of slaves by law? This would never be submitted to by the Southern States without a civil war. Do they mean to purchase their freedom? He believed their money would fall short of the price. But how is it they are more concerned in this business than others? Are they the only persons who possess religion and morality? If the people are not so exemplary, certainly they will admit the clergy are; why then do we not find them uniting in a body, praying us to adopt measures for the promotion of religion and piety, or any moral object? They know it would be an improper interference; and to say the best of this memorial, it is an act of imprudence, which he hoped would receive no countenance from the house.

Mr. SENEY (of Md.) denied that there was anything unconstitutional in the memorial, at least, if there was, it had escaped his attention, and he should be obliged to the gentleman to point it out. Its only object was, that congress should exercise their constitutional authority, to abate the horrors of slavery, as far as they could: Indeed, he considered that all altercation on the subject of commitment was at an end, as the house had impliedly determined yesterday that it should be committed.

Mr. BURKE (of S.C.) saw the disposition of the house, and he feared it would be referred to a committee, maugre all their opposition; but he must insist that it prayed for an unconstitutional measure. Did it not desire congress to interfere and abolish the slave trade, while the constitution expressly stipulated that congress should exercise no such power? He was certain the commitment would sound an alarm, and blow the trumpet of sedition in the Southern States. He was sorry to see the petitioners paid more attention to than the constitution; however, he would do his duty, and oppose the business totally; and if it was referred to a committee, as mentioned yesterday, consisting of a member from each State, and he was appointed, he would decline serving.

Mr. SCOTT, (of Penn.) I can't entertain a doubt but the memorial is strictly agreeable to the constitution: it respects a part of the duty particularly assigned to us by that instrument, and I hope we may, be inclined to take it into consideration. We can, at present, lay our hands upon a small duty of ten dollars. I would take this, and if it is all we can do, we must be content. But I am sorry that the framers of the constitution did not go farther and enable us to interdict it for good and all; for I look upon the slave-trade to be one of the most abominable things on earth; and if there was neither God nor devil, I should oppose it upon the principles of humanity and the law of nature. I cannot, for my part, conceive how any person can be said to acquire a property in another; is it by virtue of conquest? What are the rights of conquest? Some have dared to advance this monstrous principle, that the conqueror is absolute master of his conquest; that he may dispose of it as his property, and treat it as he pleases; but enough of those who reduce men to the state of transferable goods, or use them like beasts of burden; who deliver them up as the property or patrimony of another man. Let us argue on principles countenanced by reason and becoming humanity; the petitioners view the subject in a religious light, but I do not stand in need of religious motives to induce me to reprobate the traffic in human flesh; other considerations weigh with me to support the commitment of the memorial, and to support every constitutional measure likely to bring about its total abolition. Perhaps, in our legislative capacity, we can go no further than to impose a duty of ten dollars, but 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 emancipation; but I am sure I would go as far as I could.

Mr. JACKSON (of Ga.) differed with the gentleman last up, and supposed the master had a qualified property in his slave; he said the contrary doctrine would go to the destruction of every species of personal service. The gentleman said he did not stand in need of religion to induce him to reprobate slavery, but if he is guided by that evidence, which the Christian system is founded upon, he will find that religion is not against it; he will see, from Genesis to Revelation, the current setting strong that way. There never was a government on the face of the earth, but what permitted slavery. The purest sons of freedom in the Grecian republics, the citizens of Athens and Lacedaemon all held slaves. On this principle the nations of Europe are associated; it is the basis of the feudal system. But suppose all this to have been wrong, let me ask the gentleman, if it is policy to bring forward a business at this moment, likely to light up a flame of civil discord, for the people of the Southern States will resist one tyranny as soon as another; the other parts of the continent may bear them down by force of arms, but they will never suffer themselves to be divested of their property without a struggle. The gentleman says, if he was a federal judge, he does not know to what length he would go in emancipating these people; but, I believe his judgment would be of short duration in Georgia; perhaps even the existence of such a judge might be in danger.
