“I don’t know how old I am. . . . I began to work when I was about 9. I first worked for a man who used to hit me with a belt. . . . I used to sleep in the pits that had no more coal in them; I used to eat whatever I could get; I ate for a long time the candles that I found in the pits. . . .” — E. Royston Pike, 1896, adapted from Hard Times, Human Documents of the Industrial Revolution from the NYS Global History and Geography Regents Exam, June 2002.
