that was ungrateful enough to run away, I wouldn't give him up, I'd hang him.”  And whilst the nigger stepped to the door to look at the dime and bite it to see if it was good, he whispers to Jim and says: “Don't ever let on to know us.  And if you hear any digging going on nights, it's us; we're going to set you free.” Jim only had time to grab us by the hand and squeeze it; then the nigger come back, and we said we'd come again some time if the nigger wanted us to; and he said he would, more particular if it was dark, because the witches went for him mostly in the dark, and it was good to have folks around then.
