Read this excerpt from Narrative of the Life of Frederick Douglass. I was probably between seven and eight years old when I left Colonel Lloyd's plantation. I left it with joy. I shall never forget the ecstasy with which I received the intelligence that my old master (Anthony) had determined to let me go to Baltimore, to live with Mr. Hugh Auld, brother to my old master's son-in-law, Captain Thomas Auld. I received this information about three days before my departure.
