November 1908: Gastonia, North Carolina. Lacy, 12 years old, and Savannah, 11. Have worked two years. Father said "The little one is a crackerjack on spinnin', at least so the boss says. She ain't satisfied unless in the mill. The oldest one isn't so good at it. Not as quick." (Note the tense, serious looks on the younger. Older one more like a real girl.) View full size.
