They were returning from their wedding journey. Some six weeks before this date Boyson had married in Philadelphia a girl coming from one of the old Quaker stocks of that town, in whose tender steadfastness of character a man inclined both by nature and experience to expect little from life had found a happiness that amazed him. The bridegroom, also, had just been appointed to the Military Attacheship at the Berlin Embassy, and the couple were, in fact, on their way south to New York and embarkation. But there were still a few days left of the honeymoon, of which they had spent the last half in Canada, and on this May night they were journeying from Toronto along the southern shore of Lake Ontario to the pleasant Canadian hotel which overlooks the pageant of Niagara. They had left Toronto in bright sunshine, but as they turned the corner of the lake westward, a white fog had come creeping over the land as the sunset fell. But the daylight was still strong, the fog thin; so that it appeared rather as a veil of gold, amethyst, and opal, floating over the country, now parting altogether, now blotting out the orchards and the fields. And into the colour above melted the colour below. For the orchards that cover the Hamilton district of Ontario were in bloom, and the snow of the pear-trees, the flush of the peach-blossom broke everywhere through the warm cloud of pearly mist; while, just as Mrs. Boyson spoke, the train had come in sight of the long flashing line of the Welland Canal, which wound its way, outlined by huge electric lamps, through the sunset and the fog, till the lights died in that northern distance where stretched the invisible shore of the great lake. The glittering waterway, speaking of the labour and commerce of men, the blossom-laden earth, the white approaching mist, the softly falling night:--the girl-bride could not tear herself from the spectacle. She sat beside the window entranced. But her husband had captured her hand, and into the overflowing beauty of nature there stole the thrill of their love. "All very well!" said Boyson presently. "But a fog at Niagara is no joke!" The night stole on, and the cloud through which they journeyed grew denser. Up crept the fog, on stole the night. The lights of the canal faded, the orchards sank into darkness, and when the bride and bridegroom reached the station on the Canadian side the bride's pleasure had become dismay. "Oh, Alfred, we shan't see anything!" And, indeed, as their carriage made its slow progress along the road that skirts the gorge, they seemed to plunge deeper and deeper into the fog. A white darkness, as though of impenetrable yet glimmering cloud, above and around them; a white abyss beneath them; and issuing from it the thunderous voice of wild waters, dim first and distant, but growing steadily in volume and terror.
