Thomas Jefferson purchased Cary (surname unknown) from his brother, Randolph Jefferson, in 1797. Cary worked as a nailer and charcoal-burner. In 1803, fellow nailboy Brown Colbert hid Cary’s nailrod, and Cary responded by smashing a hammer on Brown Colbert’s skull. Colbert recovered but Cary was sold, likely to “negro purchasers from Georgia,” Jefferson wrote, “to make an example of him in terrorem to others, in order to maintain the police so rigorously necessary among the nail boys.”
