December 3, 1908. "A little spinner in the Mollahan Mills, Newberry, S.C. She was tending her 'sides' like a veteran, but after I took the photo, the overseer came up and said in an apologetic tone that was pathetic, 'She just happened in.' Then a moment later he repeated the information. The mills appear to be full of youngsters that 'just happened in,' or are 'helping sister.' Witness Sara R. Hine." View full size.
