"If thou wilt promise to give me the first thing that rubs itself against thy leg when thou art at home again, and to bring it here to this place in twelve years' time, thou shalt have as much money as thou wilt." The merchant thought, "What can that be but my dog?" and did not remember his little boy, so he said yes, gave the black man a written and sealed promise, and went home.
