(1) Children were аn impоrtаnt pаrt оf the labоr force during the nineteenth century. (2) One of the most unpleasant and dangerous jobs performed by children in the 1800s was chimney sweeping. (3) Employed heavily in England, “chimney sweeps”—kids as young as four or five—were sent crawling up 14 inch chimneys to remove soot and ash deposits by hand. (4) Since the chimney surfaces were generally smooth inside, only the pressure of the children’s elbows and knees kept the small boys up. (5) The black soot and ash got into cuts and scrapes caused by climbing the dark chimney shafts. (6) It also filled the lungs of children forced to do the work—causing respiratory diseases, and in some cases, death. (7) To force children to work, older boys were often employed to hold lighted straws or sharp pins to the feet of the sweeps to “encourage” them to climb higher.
