Read this excerpt from Narrative of the Life of Frederick Douglass. I spent the time in washing, not so much because I wished to, but because Mrs. Lucretia had told me I must get all the dead skin off my feet and knees before I could go to Baltimore; for the people in Baltimore were very cleanly, and would laugh at me if I looked dirty. Besides, she was going to give me a pair of trousers, which I should not put on unless I got all the dirt off me. The thought of owning a pair of trousers was great indeed! It was almost a sufficient motive, not only to make me take off what would be called by pig-drovers the mange, but the skin itself.
