"It's miles too deep for me," he admitted. "Three nights ago, when I was dining at Castle 'Cadia, Colonel Craigmiles spoke of you as a father might speak of the man whom he would like to have for a son-in-law: talked about the good old gentlemanly Kentucky stock, and all that, you know. I can't begin to sort it out."

"I am going to sort it out, some day when I have time," declared Ballard; and the hurt being temporarily repaired, they went out to superintend the arrangements for feeding the visiting throng in the big mess-tent.

After the barbecue, and more speech-making around the trestle-tables in the mess-tent, the railroad trains were brought into requisition, and various tours of inspection through the park ate out the heart of the afternoon for the visitors. Bromley took charge of that part of the entertainment, leaving Ballard to nurse his sore arm and to watch the slow submersion of the dam as the rising flood crept in little lapping waves up the sloping back-wall.

The afternoon sun beat fiercely upon the deserted construction camp, and the heat, rarely oppressive in the mountain-girt altitudes, was stifling. Down in the cook camp, Garou and his helpers were washing dishes by the crate and preparing the evening luncheon to be served after the trains returned; and the tinkling clatter of china was the only sound to replace the year-long clamour of the industries and the hoarse roar of the river through the cut-off.

Between his occasional strolls over to the dam and the canyon brink to mark the rising of the water, Ballard sat on the bungalow porch and smoked. From the time-killing point of view the great house in the upper valley loomed in mirage-like proportions in the heat haze; and by three o'clock the double line of aspens marking the river's course had disappeared in a broad band of molten silver half encircling the knoll upon which the mirage mansion swayed and shimmered.

Ballard wondered what the house-party was doing; what preparations, if any, had been made for its dispersal. For his own satisfaction he had carefully run bench-levels with his instruments from the dam height through the upper valley. When the water should reach the coping course, some three or four acres of the house-bearing knoll would form an island in the middle of the reservoir lake. The house would be completely cut off, the orchards submerged, and the nearest shore, that from which the roundabout road approached, would be fully a half-mile distant, with the water at least ten feet deep over the raised causeway of the road itself.

Surely the colonel would not subject his guests to the inconvenience of a stay at Castle 'Cadia when the house would be merely an isolated shelter upon an island in the middle of the great lake, Ballard concluded; and when the mirage effect cleared away to give him a better view, he got out the field-glass and looked for some signs of the inevitable retreat.

There were no signs, so far as he could determine. With the help of the glass he could pick out the details of the summer afternoon scene on the knoll-top; could see that there were a number of people occupying the hammocks and lazy-chairs under the tree-pillared portico; could make out two figures, which he took to be Bigelow and one of the Cantrell sisters, strolling back and forth in a lovers' walk under the shade of the maples.

It was all very perplexing. The sweet-toned little French clock on its shelf in the office room behind him had struck three, and there were only a few more hours of daylight left in Castle 'Cadia's last day as a habitable dwelling. And yet, if he could trust the evidence of his senses, the castle's garrison was making no move to escape: this though the members of it must all know that the rising of another sun would see their retreat cut off by the impounded flood.

After he had returned the field-glass to its case on the wall of the office the ticking telegraph instrument on Bromley's table called him, signing "E—T," the end-of-track on the High Line Extension. It was Bromley, wiring in to give the time of the probable return of the excursion trains for Garou's supper serving.
