"And what if you don't get back?"

He took her hand in one of his, and with the other he caressed, for a single moment, the lovely flesh of her throat. The love he had for her spoke from his eyes,—such speech as no human vision could possibly mistake. Both of them were tingling and breathless with a great, sweet wonder.

"Never let those fangs tear that softness, while you live," he told her gently. "Never let that brave old man on the sled go to his death with the pack tearing at him. Cheat 'em, Snowbird! Beat 'em the last minute, if no other way remains! Show 'em who's boss, after all—of all this forest."

"You mean—?" Her eyes widened.

"I mean that you must only spend one of those three shells in fighting off the wolves. Save that till the moment you need it most. The other two must be saved—for something else."

She nodded, shuddering an instant at a menacing shadow that moved within sixty feet of the fire. The firelight half-blinded them, dim as it was, and they couldn't see into the darkness as well as they had before. Except for strange, blue-yellow lights, close together and two and two about the fire, they might have thought that the pack was gone.

"Then good-by, Dan!" she told him. And she stretched up her arms. "The thing I said—that day on the hillside—doesn't hold any more."

His own arms encircled her, but he made no effort to claim her lips. Lennox watched them quietly; in this moment of crisis not even pretending to look away. Dan shook his head to her entreating eyes. "It isn't just a kiss, darling," he told her soberly. "It goes deeper than that. It's a symbol. It was your word, too, and mine; and words can't be broken, things being as they are. Can't I make you understand?"

She nodded. His eyes burned. Perhaps she didn't understand, as far as actual functioning of the brain was concerned. But she reached up to him, as women—knowing life in the concrete rather than the abstract—have always reached up to men; and she dimly caught the gleam of some eternal principle and right behind his words. This strong man of the mountains had given his word, had been witness to her own promise to him and to herself, and a law that goes down to the roots of life prevented him from claiming the kiss.

Many times, since the world was new, comfort—happiness—life itself have been contingent on the breaking of a law. Yet in spite of what seemed common sense, even though no punishment would forthcome if it were broken, the law has been kept. It was this way now. It wouldn't have been just a kiss such as boys and girls have always had in the moonlight. It meant the symbolic renunciation of the debt that Dan owed Cranston,—a debt that in his mind might possibly go unpaid, but which no weight of circumstance could make him renounce.
