This is a 19th century memoir written by a slave who escaped the South before the Civil War. Here's an excerpt from the intro:

"Having heard while in Slavery that "God made of one blood all nations of men," and also that the American Declaration of Independence says, that "We hold these truths to be self-evident, that all men are created equal; that they are endowed by their Creator with certain inalienable rights; that among these, are life, liberty, and the pursuit of happiness;" we could not understand by what right we were held as "chattels." Therefore, we felt perfectly justified in undertaking the dangerous and exciting task of "running a thousand miles" in order to obtain those rights which are so vividly set forth in the Declaration.

I beg those who would know the particulars of our journey, to peruse these pages.
