In order to a proper appreciation of these letters, the reader must remember that the Author speaks throughout, in the character of a Sovereign State, which had long been abused by the Abolitionists, and which had 'received some personal aggressions from Massachusetts, in regard to her Slave property and other things; as indeed had Virginia, South Carolina, and Louisiana. Massachusetts may well be considered the mother of Abolitionism; indeed _her State Abolition Society lays claim to this honor for her; and no one will dispute it with her. She has been the most restless agitator upon this subject by far, of any State in the Union.
