" And I could not see them, not from this height, but I knew they were out there, hundreds of Persons Bound to Labor too small to be seen, lost in among the long white lines of cotton. For a second or two I stared out into those distant fields, stared at the fact that when this was over, once I talked to that driver and he pointed me to the next place I had to go, I would walk out of here, and those people I could not seen but knew to be suffering, they all would be here forever. What do you do with that fact? Do you hold it like a stone in your hand? Pitch it away from this great height and watch it fall? Do you swallow it and feel it in your throat till the day you die? "
