In the month of August, 1841, I attended an anti-slavery convention in Nantucket, at which it was my happiness to become acquainted with Frederick Douglass, the writer of the following Narrative. He was a stranger to nearly every member of that body; but, having recently made his escape from the southern prison-house of bondage, and feeling his curiosity excited to ascertain the principles and measures of the abolitionists, —of whom he had heard a somewhat vague description while he was a slave, —he was induced to give his attendance, on the occasion alluded to, though at that time a resident in New Bedford.
