Just as this fatal deed was done, the door of the hall opened and King Pluto came in, followed by Mercury, who had been begging him to let his little prisoner go.

At the first noise of their coming, Proserpina took the pomegranate from her mouth.

Mercury, who saw things very quickly, noticed that Proserpina looked a little uncomfortable, and when he saw the gold plate empty, he was sure she had been eating something.

As for King Pluto, he never guessed the secret.

“My dear little Proserpina,” said the King, sitting down and drawing her gently between his knees, “here is Mercury, who tells me that a great many sad things have happened to innocent people because I have kept you a prisoner down here.  And to confess the truth I have been thinking myself that I really had no right to take you away from your mother.  It was very stupid of me, but I thought this palace was so dull, and that I should be much happier if I just had a merry little girl to play in it, and I hoped you would take my crown for a toy and let me be your playmate.  It was very foolish of me, I know.”

“No, it was not foolish,” said Proserpina, “you have been very kind to me, and I have often been quite happy here with you.”

“Thank you, dear,” said King Pluto, “but I cannot help seeing that you think my palace a dark prison and me the hard-hearted jailor, and I should, indeed, be hard-hearted if I were to keep you longer than six months.  So I give you your liberty.  Go back, dear, with Mercury, to your mother.”

Now, although you might not think so, Proserpina found it impossible to say good-by to King Pluto without being sorry, and she felt she ought to tell him about tasting the pomegranate.  She even cried a little when she thought how lonely and dull the great palace with its jeweled lamps would be after she had left.

She would like to have thanked him many times, but Mercury hurried her away.  “Come along quickly,” he said, “as King Pluto may change his mind, and take care above all things that you say nothing about the pomegranate which the servant brought you on the gold plate.”

In a short time they had passed the great gateway with the golden pillars, leaving Cerberus barking and growling with all his three heads at once, and beating his dragon tail on the ground.  Along the dark, rocky road they went very quickly, and soon they reached the upper world again.

You can guess how excited and happy Proserpina was to see the bright sunshine.  She noticed how green the grass grew on the path behind and on each side of her.  Wherever she set her foot at once there rose a flower:  violets and roses bloomed along the wayside; the grass and the corn began to grow with ten times their usual quickness to make up for the dreary months when Mother Ceres had forbidden them to appear above ground.

The hungry cattle began to eat, and went on eating all day after their long fast.  And, I can assure you, it was a busy time with all the farmers when they found that summer was coming with a rush.
