         In a moment he was sleeping peacefully and Mary Poppins said in a low voice :"West!"

     Hills and lakes, mountains and forests went round and round.This time they were on long white seachore.And before them there was a large black and very Dolphin with her baby.

    "Mary Poppins , you're just in time for and evening swim.What are you doing here ?"

     " Oh, Amelia, we are just going round the world , " Mary Poppins.

    "Well,now for a meal.What would you like ?" Amelia smiled at Jane and Michael , showing her white teth.

      " Thank you , Amelia . But we must be at home in a moment" said Mary Poppins.

       "What kind of visit is that ? Next time you must stay for tea,and we'll all sit together on a rock and sing a song to the moon ". Amelia got very sad.

       "That will be lovely " said Jane and Michael.

     "Well, bye-bye then!"

     "Bye, Amelia!"Michael and Jane cried.

    "What are you doing,Michael?" The boy heard Mary Poppins's cold voice.The sea was not there . There was green grass and Jane and the twins and Mary Poppins walking in the park.

      "Round the world and back in a minute -what a wonderful box!"said Jane.

      "It's a compass. And it's mine" said Michael . "Give it to me !"

     " My compass" said Mary Poppins and put it into her bag.

     He looked at her very angrilly.The strange feeling inside him grew worse,and in the evening he grew very naughty. He kicked the twins and pulled Jane's hair.
