At once Huldbrand made up his mind to cross the torrent. He plunged into the water, and even as he did so he seemed to see on the other shore the figure of a tall white man, who nodded his head and mocked him as he struggled on. Huldbrand knew the tall white figure only too well. It was the one that had followed him as he journeyed through the forest.
Now; in his haste to find Undine, the knight was leaping from stone to stone, sometimes slipping into the water, then with a struggle placing his feet once again upon the stones. These, tossed by the rushing stream, gave no firm foothold to the knight, and he was forced to seize the branch of a fir-tree to help him across the dangerous passage.
While he was still in the midst of the current, he heard a sweet voice crying, 'Trust not the stream, trust it not, for it is full of craft!'
The knight knew the voice. It was that of the maiden for whom he sought. Yet though he peered eagerly through the gloom he could see no trace of her.
'See! you can find me now, Sir Knight, for the moon is shining clear,' cried the voice he longed to hear, and looking around him Huldbrand saw where Undine had found a shelter. It was on a little island, beneath the branches of a great tree, that the maiden sat. There was no terror of the storm in her eyes. She was even smiling happily as she nestled amid the sweet scented grass, safe from the fury of the storm.
