The old man had loved Undine with exceeding tenderness, and it was doubtful to his mind that the mere disappearance of his beloved child could be properly viewed as her death.

But were it even granted that her corpse were lying stiff and cold at the bottom of the Danube, or swept away by the current to the ocean, still Bertalda had had some share in her death; and it was unfitting for her to step into the place of the poor injured wife.

The fisherman, however, had felt a strong regard also for the knight: this and the entreaties of his daughter, who had become much more gentle and respectful, as well as her tears for Undine, all exerted their influence, and he must at last have been forced to give up his opposition, for he remained at the castle without objection, and a messenger was sent off express to Father Heilmann, who in former and happier days had united Undine and Huldbrand, requesting him to come and perform the ceremony at the knight's second marriage.
Hardly had the holy man read through the letter from the lord of Ringstetten, ere he set out upon the journey and made much greater dispatch on his way to the castle than the messenger from it had made in reaching him.

Whenever his breath failed him in his rapid progress, or his old limbs ached with fatigue, he would say to himself: "Perhaps I shall be able to prevent a sin; then sink not, withered body, before I arrive at the end of my journey!" And with renewed vigour he pressed forward, hurrying on without rest or repose, until, late one evening, he entered the shady court-yard of the castle of Ringstetten.
The betrothed were sitting side by side under the trees, and the aged fisherman in a thoughtful mood sat near them.

The moment they saw Father Heilmann, they rose with a spring of joy, and pressed round him with eager welcome.
