How does the duke solve the problem for Jim, so he won’t have to be tied up all day if they are all gone? (CH 24-28)

To avoid tying Jim up in ropes during the day (since he has been pretending to be a runaway slave), the Duke figures out a better solution. He paints Jim in blue and makes him wear a costume. Then, he writes a sign that reads, "Sick Arab - but harmless when not out of his head." Jim is happy that he can now move around.
