Columbus, Georgia. April 1913. "Night Work! Group of boys, all working in Massey Hosiery Mills. Most of them had been working all day and had an hour for supper and were going back into the mill (6 p.m.) to work until 8 as they have done several nights this week and for some time past. I found four 10-year-olds and several of 11 and 12 working in the evening after supper and they said it was a regular thing. Ferrell Butler, 10 yrs old, 1114 21st St., been working off and on one year. Marvin Williams, 11 yrs. old been working one year part of the time at night. Lawrence Webb, 12 yrs. Old. Jack Wright, 15 yrs. working three yrs., couldn't write his own name." View full size. Photo and caption by Lewis Wickes Hine.
