'Open the door, my Princess dear, open the door to thy true love here!
     And mind the words that thou and I said by the fountain cool, in the greenwood shade.'

They then took leave of the king, and got into the coach with eight horses, and all set out, full of joy and merriment,
for the Prince's kingdom, which they reached safely; and there they lived happily a great many years.
