"It's magic, your Highness," said the cook solemnly.

"It's one of the curious things Zog is able to do.

But you must remember all this place is a big cave in which the castle stands, so the light is never seen by anyone except those who live here." "But why does Zog keep his light going all the time ?" asked the Queen.

When dinner was over, however, and Cap'n Joe had gone back to his work of sewing on buttons and the servants had carried away the dishes, the prisoners remembered their troubles and the fate that awaited them.
