But the orator was preparing to do a little of the hitting, himself. The appearance of the party at the mine entrance had not gone unremarked, and the company's secretary recognised the company's enemy at a glance. He was looking over the heads of the celebrators and down upon the group on the opposite side of the narrow chasm when he said:

"So, ladies and gentlemen, this great project, in the face of the most obstinate, and, I may say, lawless, opposition; in spite of violence and petty obstruction on the part of those who would rejoice, even to-day, in its failure; this great work has been carried on to its triumphant conclusion, and we are gathered here on this beautiful morning in the bright sunshine and under the shadow of these magnificent mountains to witness the final momentous act which shall add the finishing stone to this grand structure; a structure which shall endure and subserve its useful and fructifying purpose so long as these mighty mountains rear their snowy heads to look down in approving majesty upon a desert made fair and beautiful by the hand of man."

Hand-clappings, cheers, a stirring of the crowd, and the upstarting of the brass band climaxed the rhetorical peroration, and Elsa glanced anxiously over her shoulder. She knew her father's temper and the fierce quality of it when the provocation was great enough to arouse it; but he was sitting quietly between Dosia and Madge Cantrell, and the publicly administered affront seemed to have missed him.

When the blare of brass ceased, the mechanical part of the spectacle held the stage for a few brief minutes. The completing stone was carefully toggled in the grappling-hooks of the derrick-fall, and at Ballard's signal the hoisting engine coughed sharply, besprinkling the spectators liberally with a shower of cinders, the derrick-boom swung around, and the stone was lowered cautiously into its place.

With a final rasping of trowels, the workmen finished their task, and Ballard walked out upon the abutment and laid his hand on the wheel controlling the drop-gate which would cut off the escape of the river through the outlet tunnel. There was a moment of impressive silence, and Elsa held her breath. The day, the hour, the instant which her father had striven so desperately to avert had come. Would it pass without its tragedy?

She saw Ballard give the last searching glance at the gate mechanism; saw President Pelham step out to give the signal. Then there was a stir in the group behind her, and she became conscious that her father was on his feet; that his voice was dominating the droning roar of the torrent and the muttering of the thunder on the far-distant heights.

"Mistuh-uh Pelham—and you otheh gentlemen of the Arcadia Company—you have seen fit to affront me, suhs, in the most public manneh, befo' the members of my family and my guests. This was youh privilege, and you have used it acco'ding to youh gifts. Neve'theless, it shall not be said that I failed in my neighbo'ly duty at this crisis. Gentlemen, when you close that gate——"

The president turned impatiently and waved his hand to Ballard. The band struck up "The Star-Spangled Banner," a round ball of bunting shot to the top of the flagstaff over the band-stand and broke out in a broad flag, and Elsa saw the starting-wheel turning slowly under Ballard's hand. The clapping and cheering and the band clamour drowned all other sounds; and the colonel's daughter, rising to stand beside Wingfield, felt rather than heard the jarring shock of a near-by explosion punctuating the plunge of the great gate as it was driven down by the geared power-screws.

What followed passed unnoticed by the wildly cheering spectators crowding the canyon brink to see the foaming, churning torrent recoil upon itself and beat fiercely upon the lowered gate and the steep-sloped wall of the dam's foundation courses. But Elsa saw Ballard start as from the touch of a hot iron; saw Bromley run out quickly to lay hold of him. Most terrible of all, she turned swiftly to see her father coming out of the mine entrance with a gun in his hands—saw and understood.

It was Wingfield, seeing all that she saw and understanding quite as clearly, who came to her rescue at a moment when the bright August sunshine was filling with dancing black motes for her.
