"The realities will hit us soon enough," growled Ballard, whose impatience took the morose form. Then, with a sudden righting of his tilted camp-stool: "Good Lord, Loudon! Look yonder—up the canyon!"

The porch outlook commanded a view of the foothill canyon, and of a limited area of the bowl-shaped upper valley. At the canyon head, and on the opposite side of the river, three double-seated buckboards were wheeling to disembark their passengers; and presently the Castle 'Cadia house-party, led by Colonel Craigmiles himself, climbed the left-hand path to the little level space fronting the mysterious mine.

"By Jove!" gasped Bromley; "I nearly had a fit—I thought they were coming over here. Now what in the name of——"

"It's all right," cut in Ballard, irritably. "Why shouldn't the colonel want to be present at his own funeral? And you needn't be afraid of their coming over here. The colonel wouldn't wipe his feet on that mob of money-hunters around the band-stand. See; they are making a private box of the mine entrance."

The remark framed itself upon the fact. At the colonel's signal the iron-bound tunnel door had swung open, and Wingfield and Blacklock, junior, with the help of the buckboard drivers, were piling timbers on the little plateau for the party's seating.

It was Colonel Craigmiles's own proposal, this descent upon the commercial festivities at the dam; and Elsa had yielded only after exhausting her ingenuity in trying to defeat it. She had known in advance that it could not be defeated. For weeks her father's attitude had been explainable only upon a single hypothesis; one which she had alternately accepted and rejected a hundred times during the two years of dam-building; and this excursion was less singular than many other consequences of the mysterious attitude.

She was recalling the mysteries as she sat on the pile of timbers with Wingfield, hearing but not heeding the resounding periods of the orator across the narrow chasm. With the inundation of the upper valley an impending certainty, measurable by weeks and then by days, and now by hours, nothing of any consequence had been done at Castle 'Cadia by way of preparing for it. Coming down early one morning to cut flowers for the breakfast-table, she had found two men in mechanics' overclothes installing a small gasolene electric plant near the stables; this, she supposed, was for the house-lighting when the laboratory should be submerged. A few days later she had come upon Otto, the chauffeur, building a light rowboat in a secluded nook in the upper canyon.

But beyond these apparently trivial precautions, nothing had been done, and her father had said no word to her or to the guests of what was to be done when the closed-in valley should become a lake with Castle 'Cadia for its single island. Meanwhile, the daily routine of the country house had gone on uninterruptedly; and once, when Mrs. Van Bryck had asked her host what would happen when the floods came, Elsa had heard her father laughingly assure his guest in the presence of the others that nothing would happen.

That Wingfield knew more than these surface indications could tell the keenest observer, Elsa was well convinced; how much more, she could only guess. But one thing was certain: ever since the day spent with Ballard and Bromley and Jerry Blacklock at the construction camp—the day of his narrow escape from death—the playwright had been a changed man; cynical, ill at ease, or profoundly abstracted by turns, and never less companionable than at the present moment while he sat beside her on the timber balk, scowling up and across at the band-stand, at the spellbound throng ringing it in, and at the spellbinding secretary shaming the pouring torrent in the ravine below with his flood of rhetoric.

"What sickening rot!" he scoffed in open disgust. And then: "It must be delightfully comforting to Ballard and Bromley to have that wild ass of the market-place braying over their work! Somebody ought to hit him."
