something on a paper and read it over, and says: “There; you see it says 'for a consideration.'  That means I have bought it of you and paid you for it.  Here's a dollar for you.  Now you sign it.” So I signed it, and left. Miss Watson's nigger, Jim, had a hair-ball as big as your fist, which had been took out of the fourth stomach of an ox, and he used to do magic with it.  He said there was a spirit inside of it, and it knowed everything.  So I went to him that night and told him pap was here again, for I found his tracks in the snow.  What I wanted to know was, what he was going to do, and was he going to stay?  Jim got out his hair-ball and said something over it, and then he held it up and dropped it on the floor.  It fell pretty solid, and only rolled about an inch.  Jim tried it again, and then another time, and it acted just the same.  Jim got down on his knees, and put his ear against it and listened.  But it warn't no use; he said it wouldn't talk. He said sometimes it wouldn't talk without money.  I told him I had an old slick counterfeit quarter that warn't no good because the brass showed through the silver a little, and it wouldn't pass nohow, even if the brass didn't show, because it was so slick it felt greasy, and so that would tell on it every time.  (I reckoned I wouldn't say nothing about the dollar I got from the judge.) I said it was pretty bad money, but maybe the hair-ball would take it, because maybe it wouldn't know the difference.  Jim smelt it and bit it and rubbed it, and said he would manage so the hair-ball would think it was good.  He said he would split open a raw Irish potato and stick the quarter in between and keep it there all night, and next morning you couldn't see no brass, and it wouldn't feel greasy no more, and so anybody in town would take it in a minute, let alone a hair-ball.  Well, I knowed a potato would do that before, but I had forgot it. Jim put the quarter under the hair-ball, and got down and listened again.
