Read the excerpt from Narrative of the Life of Frederick Douglass. And to cap the climax of their base ingratitude and fiendish barbarity, my grandmother, who was now very old, having outlived my old master and all his children, having seen the beginning and end of all of them, and her present owners finding she was of but little value, her frame already racked with the pains of old age, and complete helplessness fast stealing over her once active limbs, they took her to the woods, built her a little hut, put up a little mud chimney, and then made her welcome to the privilege of supporting herself there in perfect loneliness; thus virtually turning her out to die!
