UP FROM SLAVERY (Chapter 3) by Booker T. Washington
'I swept the recitation-room three times. Then I got a dusting-cloth and dusted it four times. All the woodwork around the walls, every bench, table, and desk, I went over four times with my dusting-cloth. .....I reported to the head teacher. She was a "Yankee" woman who knew just where to look for dirt. ... When she was unable to find one bit of dirt on the floor, or a particle of dust on any of the furniture, she ... remarked, "I guess you will do to enter this institution." -B. T. Washington
