'Come with me,' she cried when she saw them, 'come with me and I will show you a cask which the stream has thrown ashore. If it is not a wine cask you may punish me as you will.'
The men went with her, and there in a little creek they found the cask and began to roll it toward the cottage.
But though they rolled it rapidly the storm crept quickly up. So black were the clouds, so threatening, that it seemed each moment that the rain would burst forth upon them.
Undine helped the men to roll the cask, and as the sky grew yet more threatening she looked up at the dark clouds and said in a warning voice, 'Beware, beware that you wet us not.'
'It is wrong of you thus to try to rebuke the storm,' said her foster-father, but at his words the maiden only laughed low to herself in the darkness.
It would seem, however, that Undine's warning had been of use, for it was not until the cask was rolled in at the cottage door that the storm broke.
By the bright glow of the fire they opened the cask and found that it did indeed hold wine. They tasted it and found it very good, and soon they were once more as gay as the maiden could wish.
Then suddenly the fisherman grew grave, grieving for him who had lost the cask.
'Nay, grieve not,' said the knight, 'I will seek for the owner and repay him for his loss when I come again to my castle at Ringstetten.'
The fisherman smiled and was content.
Undine, however, was angry with the knight. 'It is foolish,' said she, 'to talk of seeking for the owner of the cask. Were you lost in the search I should weep. Would you not rather stay by my side?'
'Yes, and that do you right well know,' answered the knight.
'Then,' said the maiden, 'why should you speak of helping other people. It is but foolish talk.'
The foster-mother sighed as she listened to Undine's careless words, while the fisherman forgot his usual quiet and scolded her sharply.
'Your words are wild, and are such as no Christian maiden should utter,' he said. 'May God forgive both you and those who have allowed you thus to speak.'
'It is indeed true,' said Undine, 'that as I think I speak. Why, therefore, should you scold me for my words.'
'Say no more,' said the fisherman, for he was very angry.
