"1. How many societies, affiliated with that of which you are corresponding secretary, are there in the United States? And how many members belong to them IN THE AGGREGATE?"

ANSWER.--Our anniversary is held on the Tuesday immediately preceding the second Thursday in May. Returns of societies are made only a short time before. In May, 1835, there were 225 auxiliaries reported. In May, 1836, 527. In May, 1837, 1006. Returns for the anniversary in May next have not come in yet. It may, however, be safely said, that the increase, since last May, is not less than 400.[[A]] Of late, the multiplication of societies has not kept pace with the progress of our principles. Where these are well received, our agents are not so careful to organize societies as in former times, when our numbers were few; societies, now, being not deemed so necessary for the advancement of our cause. The auxiliaries average not less than 80 members each; making an aggregate of 112,480. Others estimate the auxiliaries at 1500, and the average of members at 100. I give you, what I believe to be the lowest numbers.

[Footnote [A]: The number reported for May was three hundred and forty, making, in the aggregate, 1346.--Report for May, 1838.]

"2. Are there any other societies similar to yours, and not affiliated with it in the United States? And how many, and what is the aggregate of their members?"

ANSWER.--Several societies have been formed in the Methodist connection within the last two years,--although most of the Methodists who are abolitionists, are members of societies auxiliary to the American. These societies have been originated by Ministers, and others of weight and influence, who think that their brethren can be more easily persuaded, as a religious body, to aid in the anti-slavery movement by this twofold action. None of the large religious denominations bid fairer soon to be on the side of emancipation than the Methodist. Of the number of the Methodist societies that are not auxiliary, I am not informed.--The ILLINOIS SOCIETY comes under the same class. The REV. ELIJAH P. LOVEJOY, the corresponding secretary, was slain by a mob, a few days after its organization. It has not held a meeting since; and I have no data for stating the number of its members. It is supposed not to be large.--Neither is the DELAWARE SOCIETY, organized, a few weeks ago, at Wilmington, auxiliary to the American. I have no information as to its numbers.--The MANUMISSION SOCIETY in this city, formed in 1785, with JOHN JAY its first, and ALEXANDER HAMILTON its second president, might, from its name, be supposed to be affiliated with the American. Originally, its object, so far as regarded the slaves, and those illegally held in bondage in this state, was, in a great measure, similar. Slavery being extinguished in New-York in 1827, as a state system, the efforts of the Manumission Society are limited now to the rescue, from kidnappers and others, of such persons as are really free by the laws, but who have been reduced to slavery. Of the old Abolition societies, organized in the time, and under the influence of Franklin and Rush and Jay, and the most active of their coadjutors, but few remain. Their declension may be ascribed to this defect,--they did not inflexibly ask for immediate emancipation.--The PENNSYLVANIA ABOLITION SOCIETY, formed in 1789, with DR. FRANKLIN, president, and DR. RUSH, secretary, is still in existence--but unconnected with the American Society. Some of the most active and benevolent members of both the associations last named, are members of the American Society. Besides the societies already mentioned, there may be in the country a few others of anti-slavery name; but they are of small note and efficiency, and are unconnected with this.

"3. Have you affiliation, intercourse, or connection with any similar societies out of the United States, and in what countries?"

ANSWER.--A few societies have spontaneously sprung up in Canada. Two have declared themselves auxiliary to the American. We have an agent--a native of the United States--in Upper Canada; not with a view to the organization of societies, but to the moral and intellectual elevation of the Ten thousand colored people there; most of whom have escaped from slavery in this Republic, to enjoy freedom under the protection of a Monarchy. In Great Britain there are numerous Anti-slavery Societies, whose particular object, of late, has been, to bring about the abolition of the Apprentice-system, as established by the emancipation act in her slaveholding colonies. In England, there is a society whose professed object is, to abolish slavery throughout the world. Of the existence of the British societies, you are, doubtless, fully aware; as also of the fact, that, in Britain, the great mass of the people are opposed to slavery as it existed, a little while ago, in their own colonies, and as it exists now in the United States.--In France, the "FRENCH SOCIETY FOR THE ABOLITION OF SLAVERY" was founded in 1834. I shall have the pleasure of transmitting to you two pamphlets, containing an account of some of its proceedings; from which you will learn, that, the DUC DE BROGLIE is its presiding officer, and many of the most distinguished and influential of the public men of that country are members.--In Hayti, also, "The HAYTIAN ABOLITION SOCIETY" was formed in May, 1836.

These are all the foreign societies of which I have knowledge. They are connected with the American by no formal affiliation. The only intercourse between them and it, is, that which springs up spontaneously among those of every land who sympathize with Humanity in her conflicts with Slavery.

"4. Do your or similar societies exist in the Colleges and other Literary institutions of the non-slaveholding states, and to what extent?"

ANSWER.--Strenuous efforts have been made, and they are still being made, by those who have the direction of most of the literary and theological institutions in the free states, to bar out our principles and doctrines, and prevent the formation of societies among the students. To this course they have been prompted by various, and possibly, in their view, good motives. One of them, I think it not uncharitable to say, is, to conciliate the wealthy of the south, that they may send their sons to the north, to swell the college catalogues. Neither do I think it uncharitable to say, that in this we have a manifestation of that Aristocratic pride, which, feeling itself honored by having entrusted to its charge the sons of distant, opulent, and distinguished planters, fails not to dull everything like sympathy for those whose unpaid toil supplies the means so lavishly expended in educating southern youth at northern colleges. These efforts at suppression or restraint, on the part of Faculties and Boards of Trustees, have heretofore succeeded to a considerable extent. Anti-Slavery Societies, notwithstanding, have been formed in a few of our most distinguished colleges and theological seminaries. Public opinion is beginning to call for a relaxation of restraints and impositions; they are yielding to its demands; and now, for the most part, sympathy for the slave may be manifested by our generous college youth, in the institution of Anti-Slavery Societies, without any downright prohibition by their more politic teachers. College societies will probably increase more rapidly hereafter; as, in addition to the removal or relaxation of former restraints, just referred to, the murder of Mr. Lovejoy, the assaults on the Freedom of speech and of the press, the prostration of the Right of petition in Congress, &c, &c, all believed to have been perpetrated to secure slavery from the scrutiny that the intelligent world is demanding, have greatly augmented the number of college abolitionists. They are, for the most part, the diligent, the intellectual, the religious of the students. United in societies, their influence is generally extensively felt in the surrounding region; dispersed, it seems scarcely less effective. An instance of the latter deserves particular notice.
