"We must have known each other before," she often used to say to her. "or else, there must be some mysterious connection between us, for one does not love another as dearly as I have loved you from the first moment of our meeting without some cause--some deep and secret cause." And Bertalda also could not deny the fact that she felt drawn to Undine with a tender feeling of confidence, however much she might consider that she had cause for the bitterest lamentation at this successful rival. Biassed by this mutual affection, they both persuaded--the one her foster-parents, the other her husband--to postpone the day of departure from time to time; indeed, it was even proposed that Bertalda should accompany Undine for a time to castle Ringstetten, near the source of the Danube.
They were talking over this plan one beautiful evening, as they were walking by starlight in the large square of the Imperial city, under the tall trees that enclose it. The young married pair had incited Bertalda to join them in their evening walk, and all three were strolling up and down under the dark-blue sky, often interrupting their familiar talk to admire the magnificent fountain in the middle of the square, as its waters rushed and bubbled forth with wonderful beauty. It hid a soothing happy influence upon them; between the shadows of the trees there stole glimmerings of light from the adjacent houses; a low murmur of children at play, and of others enjoying their walk, floated around them; they were so alone, and yet in the midst of the bright and living world; whatever had appeared difficult by day, now became smooth as of itself; and the three friends could no longer understand why the slightest hesitation had existed with regard to Bertalda's visit to Ringstetten. Presently, just as they were on the point of fixing the day for their common departure, a tall man approached them from the middle of the square, bowed respectfully to the company, and said something in the ear of the young wife. Displeased as she was at the interruption and its cause, she stepped a little aside with the stranger, and both began to whisper together, as it seemed, in a foreign tongue. Huldbrand fancied he knew the strange man, and he stared so fixedly at him that he neither heard nor answered Bertalda's astonished inquiries.
All at once Undine, clapping her hands joyfully, and laughing, quitted the stranger's side, who, shaking his head, retired hastily and discontentedly, and vanished in the fountain. Huldbrand now felt certain on the point, but Bertalda asked: "And what did the master of the fountain want with you, dear Undine?"
The young wife laughed within herself, and replied: "The day after to-morrow, my dear child, on the anniversary of your name-day, you shall know it." And nothing more would she disclose. She invited Bertalda and sent an invitation to her foster-parents, to dine with them on the appointed day, and soon after they parted.
"Kuhleborn? was it Kuhleborn?" said Huldbrand, with a secret shudder, to his beautiful bride, when they had taken leave of Bertalda, and were now going home through the darkening streets.
"Yes, it was he," replied Undine, "and he was going to say all sorts of nonsensical things to me. But, in the midst, quite contrary to his intention, he delighted me with a most welcome piece of news. If you wish to hear it at once, my dear lord and husband, you have but to command, and I will tell it you without reserve. But if you would confer a real pleasure on your Undine, you will wait till the day after to-morrow, and you will then have your share too in the surprise."
The knight gladly complied with his wife's desire, which had been urged so sweetly, and as she fell asleep, she murmured smilingly to herself: "Dear, dear Bertalda! How she will rejoice and be astonished at what her master of the fountain told me!"
