One afternoon Thomas Savine entered the sick man's room in a state of complacent satisfaction.

"Glad to see you getting ahead so fast, and you must hurry, for we'll want you soon," he said. "The great charge is to be fired the day after to-morrow. Shackleby, who was at the bottom of the whole opposition, has cleared out with considerable expedition. Sold all his stock in the Company, and if his colleagues knew much about his doings, which is quite possible, they emphatically disown them. As a result I've made one or two good provisional deals with them, and expect no more trouble. In short, everything points to a great success."

When Savine went out Geoffrey beckoned Helen to him.

"I am getting so well that you must leave me to your aunt to-morrow," he said. "You remember your promise to fire the decisive charge for me, and I hope when you see it you will approve of the electric firing key. Tell your father I owe more to him than the doctor, for I should have worried myself beyond the reach of physic if he had not been there to take charge instead of me—that is to say, before you came to cure me."

"I will go," agreed Helen, with signs of suppressed agitation that puzzled Geoffrey. She knew that after that charge had been fired their present relations, pleasant as they were, could not continue. It appeared to her the climax to which all he had dared and suffered, and with a humility that was yet akin to pride she had determined, in reparation, voluntarily to offer him that which, whether victorious or defeated otherwise, he had with infinite patience and loyal service won.

It was early one clear cold morning when Helen Savine stood on a little plank platform perched high in a hollow of the rock walls overhanging the river opposite Thurston's camp. Each detail of the scene burned itself into her memory as she gazed about her under a tense expectancy—the rift of blue sky between the filigree of dark pines high above, the rush of white-streaked water thundering down the gorge below and frothing high about the massive boulders, and one huge fang of promontory which a touch of her finger would, if all went well, reduce to chaotic débris. Groups of workmen waited on the opposite side of the flood, all staring towards her expectantly, and Thomas Savine stood close by holding an insignificant box with wires attached to it, in a hand that was not quite steady. Tom from Mattawa sat perched upon a spire of rock holding up a furled flag, and her father leaned heavily upon the rails of the staging. No one spoke or stirred, and in spite of the roar of hurrying water a deep oppressive silence seemed to brood over cañon and camp.

"This is the key," said Thomas Savine. "It is some notion of Geoffrey's, and he had it made especially in Toronto. You fit it in here."

Helen glanced at the diminutive object before she took the box. The finger grip had been fashioned out of a dollar cut clean across bearing two dates engraved upon it. The first, it flashed upon her, was the one on which she had given the worn-out man that very coin, while the other had evidently been added more recently, with less skill, by some camp artificer.

"It's to-day," said Thomas Savine following her eyes, and Helen noticed that his voice was strained. "Geoffrey told me to get it done. Quaint idea; don't know what it means. But put us out of suspense. We're all waiting."

Helen knew what the dates meant, and appreciated the delicate compliment. It was she who had started the daring contractor on his career who was to complete his triumph, and she drew a deep breath as she looked down into the thundering gorge realizing it was a great fight he had won. Human courage and dogged endurance, inspired by him, had mocked at the might of the river, and, blasting a new pathway for it through the adamantine heart of the hills, would roll back the barren waters from a good land that the stout of heart and arm might enter in. Swamps would give place to wheat fields, orchards blossom where willow swale had been, herds of cattle fatten on the levels of the lake, and the smoke of prosperous homesteads drift across dark forests where, for centuries, the wolf and deer had roamed undisturbed. That was one aspect only, but she knew the man who loved her had won a greater triumph over his own nature and others' passions and infirmities.
