During the two weeks which they spent in the Canadian capital, they were most hospitably entertained by various persons of high birth and breeding in that city. They were also included among the guests at the ball given by the governor-general at Rideau Hall, where the man who, as “Prado,” was some years later to suffer an ignominious death at the hands of M. Deibler (the Paris executioner) had the honor of dancing with the illustrious personage who at that time graced the vice-regal mansion with her presence.

At the conclusion of their visit to Ottawa, the three young men started for Niagara Falls, which they were anxious to see, and on arriving there, took up their residence at one of the principal hotels on the Canadian side of the cataract.

The day after their arrival was spent in visiting the Cave of the Winds, and other sights of the place. That same evening, after dinner, Frederick, leaving his two friends playing billiards at the hotel, lighted a cigar, and strolled down toward the Falls. As he was walking along the edge of the precipitous bank of the mighty torrent, he suddenly heard footsteps advancing toward him from the opposite direction. Raising his eyes to see who the stranger might be, he recognized, to his horror, in the bright moonlight, the last person on earth whom he wished to meet—the husband of Nina, Mr. Van der Beck.

Frederick hoped that Nina's husband would fail to recognize him, and pulling his hat down over his eyes quickened his pace for the purpose of preventing the latter from obtaining a glimpse of his features. His onward course, however, was brought to a sudden stop by Mr. Van der Beck, who, courteously raising his hat, requested him to give him a light for his cigar. As the two men stood face to face, the moon, which for a moment past had been obscured by a fleeting cloud, suddenly shone forth again, casting its bright rays full on Frederick's face.

With a hoarse cry, the old man started back when he recognized the man who had so grievously wronged him. His face assumed a terrible expression; his eyes glittered fiercely, and, trembling with suppressed fury from head to foot, he seemed for a moment unable to speak.

The situation was truly an awful one for both.

In striking contrast with the violent passions which surged in the breasts of both the husband and lover of the ill-fated Nina Van der Beck was the deep calm and loveliness of the scene around them. Not a breath of wind stirred the lofty branches of the trees. The moon was sailing majestically across the dark heavens, shedding a light so bright and pure that every blade of grass, every pebble in the path was distinguishable in the silvery sheen. Many feet beneath them, they could hear the mighty rush of waters as they sped on their tumultuous course between their rocky banks, and from a short distance off came the dull and unceasing roar of the great Niagara Falls.

At length Mr. Van der Beck broke the silence and exclaimed in a dry, hollow voice:

“I have caught you at last, Frederick Gavard. My hour has come! God help you, for I have much to avenge.”

Frederick, who had by this time regained all his habitual composure, contemptuously shrugged his shoulders and replied with a sneer:
