They enjoyed themselves very much, but by-and-by the copper treasury began to get warmer and warmer, and suddenly the junior secretary cried out, "Look at the bottle!" The bottle sealed with Solomon's seal had swollen to three times its proper size and seemed to be nearly red hot, and the air got warmer and warmer and the bottle bigger and bigger, till all the junior secretaries agreed that the place was too hot to hold them, and out they went, tumbling over each other in their haste, and just as the last got out and locked the door the bottle burst, and out came the dragon, very fiery, and swelling more and more every minute, and he began to eat the sacks of gold and crunch up the pearls and diamonds and rubies as if they were sugar. By breakfasttime he had devoured the whole of the Prince's treasures, and when the Prince came along the street at about eleven, he met the dragon coming out of the broken door of the Treasury, with molten gold still dripping from his jaws. Then the Prince turned and ran for his life, and as he ran toward the dragonproof tower the little white Princess saw him coming, and she ran down and unlocked the door and let him in, and slammed the dragonproof door in the fiery face of the dragon, who sat down and whined outside, because he wanted the Prince very much indeed. The Princess took Prince Tiresome into the best room, and laid the cloth, and gave him cream and eggs and white grapes and honey and bread, with many other things, yellow and white and good to eat, and she served him just as kindly as she would have done if he had been anyone else instead of the bad Prince who had taken away her kingdom and kept it for himself--because she was a true Princess and had a heart of gold. When he had eaten and drunk, he begged the Princess to show him how to lock and unlock the door. The nurse was asleep, so there was no one to tell the Princess not to, and she did. [Illustration: "The junior secretary cried out, 'Look at the bottle!'" _See page 129._] "You turn the key like this," she said, "and the door keeps shut. But turn it nine times around the wrong way, and the door flies open." And so it did. And the moment it opened, the Prince pushed the white Princess out of her tower, just as he had pushed her out of her kingdom, and shut the door. For he wanted to have the tower all for himself. And there she was, in the street, and on the other side of the way the dragon was sitting whining, but he did not try to eat her, because--though the old nurse did not know it--dragons cannot eat white Princesses with hearts of gold. The Princess could not walk through the streets of the town in her milky-silky gown with the daisies on it, and with no hat and no gloves, so she turned the other way, and ran out across the meadows, toward the wood. She had never been out of her tower before, and the soft grass under her feet felt like grass of Paradise.
