And Ozma has an enchanted picture hanging in her room that shows her the exact scene where any of her friends may be , at any time she chooses . All she has to do is to say : ` I wonder what So-and-so is doing , ' and at once the picture shows where her friend is and what the friend is doing . That 's REAL magic , Mr. Wizard ; is n't it ? Well , every day at four o'clock Ozma has promised to look at me in that picture , and if I am in need of help I am to make her a certain sign and she will put on the Nome King 's Magic Belt and wish me to be with her in Oz .
