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.
