"You, rider of the black horse, make that," said Prince Underwaves, "before the morrow's sun rises."
The lad went out to the horse and leaned his elbow on his neck and sighed, thinking that this castle never could be made for ever.
"There never came a turn in my road yet that is easier for me to pass than this," said the black horse.
Glance that the lad gave from him he saw all that there were, and ever so many wrights and stone masons at work, and the castle was ready before the sun rose.
He shouted at the Prince Underwaves, and he saw the castle. He tried to pluck out his eye, thinking that it was a false sight.
"Son of King Underwaves," said the rider of the black horse, "don't think that you have a false sight; this is a true sight."
"That's true," said the prince. "You are a son of success, but I am a son of success too. There will be no more mistakes and delays, but a wedding now."
"No," said she. "The time is come. Should we not go to look at the castle? There's time enough to get married before the night comes."
They went to the castle and the castle was without a "but"——
"I see one," said the prince. "One want at least to be made good. A well to be made inside, so that water may not be far to fetch when there is a feast or a wedding in the castle."
