Read the passage from Incidents in the Life of a Slave Girl by Harriet Jacobs.

I clasped the hand of my good uncle, to whom I owed so much, and of Peter, the brave, generous friend who had volunteered to run such terrible risks to secure my safety. To this day I remember how bright his face beamed with joy, when he told me he had discovered a safe method for me to escape. Yet that intelligent, enterprising, noble-hearted man was a ! liable, by the laws of a country that calls itself civilized, to be sold with horses and pigs! We parted in silence. Our hearts were all too full for words!
