In a room of the Royal Palace of the Emerald City of Oz hangs a Magic Picture, in which are shown all the important scenes that transpire in those fairy dominions. The scenes shift constantly and by watching them, Ozma, the girl Ruler, is able to discover events taking place in any part of her kingdom.One day she saw in her Magic Picture that a little girl and a little boy had wandered together into a great, gloomy forest at the far west of Oz and had become hopelessly lost. Their friends were seeking them in the wrong direction and unless Ozma came to their rescue the little ones would never be found in time to save them from starving.So the Princess sent a message to Jack Pumpkinhead and asked him to come to the palace. This personage, one of the queerest of the queer inhabitants of Oz, was an old friend and companion of Ozma. His form was made of rough sticks fitted together and dressed in ordinary clothes. His head was a pumpkin with a face carved upon it, and was set on top a sharp stake which formed his neck.Jack was active, good-natured and a general favorite; but his pumpkin head was likely to spoil with age, so in order to secure a good supply of heads he grew a big field of pumpkins and lived in the middle of it, his house being a huge pumpkin hollowed out. Whenever he needed a new head he picked a pumpkin, carved a face on it and stuck it upon the stake of his neck, throwing away the old head as of no further use.
