n 1936, a formerly enslaved man named Prince Smith described it to a government interviewer: a wooden box, barely tall enough to stand in, no room to sit or lie down, locked in direct sunlight for days. Some overseers called it the humane option — because unlike a whip, it left no marks. No visible scars meant no questions from buyers or visitors. The suffering was entirely invisible from the outside. That was exactly the point. His account is in the Library of Congress. So are hundreds like it. #BlackHistory #HiddenHistory #AmericanHistory #SlaveryHistory
