Last spring I attended the Ohio Anti-Slavery Convention; was present at the several meetings of the American Anti-Slavery Society in New York, and at the Anti-Slavery Convention held in Boston. On these several occasions, I became acquainted, and deliberated with, it may be, not less than one thousand persons, who may be fairly set down as among the most intelligent of the abolitionists. Subjects on which the most diverse opinions were entertained, and which to ambitious and untrained minds would be agitating and dissensious in the extreme, were discussed with the most calm and unruffled composure. And while some of the leading journals were teeming with the foulest and the falsest charges of moral and political turpitude; while there were produced in their assemblies placards, calling on the mob for appropriate deeds, and designating the time and place of holding their meetings, that its violence might know at what point it might most effectually spend itself; yet, never elsewhere have I seen so much of sedate deliberation of sober conclusion, of dignified moderation, sanctified by earnest prayer to God, not only for the oppressed, but for the oppressor of his fellow; not only for such as they loved, but for their slanderers, and persecutors, and enemies. The above is a fair account, so far as my knowledge enables me to speak, of the character of those whom you are pleased to describe "a band of fanatical abolitionists." Light and rash minds, unaccustomed to penetrate to the real causes of great revolutions in public sentiment, will, of course, think and speak contemptuously of them, while the philosophic observer clearly sees, that such antagonists of error, armed with so powerful a weapon as the Truth, must, at all times, be invincible; and that in the end they will be triumphant.
