Steve was sitting up in his rocking-chair.

"I didn't hand you that stuff and my story of these things for pastime, Doc. I guess I'd learnt all you've told me from the books and papers of the boy's father. Knowing you for the man you are, and the way you most generally try to make a ten-pound heart look like a sparrow's egg by shouting at folks, I reckoned you'd see with me in this thing. That poor feller Brand. As you say, his work isn't to be wasted. He's left behind him a kiddie which hasn't a thing in the world, and if I'm any judge of things that kiddie was the whole sun, moon, and stars of his life. I'm thinking of that kiddie now. And I'm thinking of him alone. You're thinking of a suffering world. If there's twenty-five thousand dollars for a half pint of that dope the money belongs to the helpless kid of the man who's given his life to locate it. We don't need an outfit to get the neches' secret. We don't need a thing. There's just one man knows how to locate the place where Marcel Brand lived, and that's me. There's not a living soul, not even Julyman, or Oolak, or An-ina, could ever make it without me. And I tell you right here there's no one ever learns it from me. That secret is for Marcel, and I figure to hand it to him, and all that's coming out of it. That's why I've told you these things. Now you'll understand what's in my mind when I say that I'm coming along back when I've settled with Garstaing, or failed to locate him. If I've settled with him I'll be in a hurry. And I'm going up north—north where no one can ever hope to follow me, with An-ina, and Marcel, and maybe Julyman and Oolak again, and I'm going to work this thing for the rest of my life for—Marcel. It's his, all of it. And what's left over is for the suffering humanity you're thinking about. See, here, Doc, you and me, we aren't any sort of twin brothers of friends. We haven't been raised together. I hadn't a notion of you till I took charge of this station. But I know a man—a real man. And if you've the guts I reckon you have, then you'll help me to do the thing that's going to shut the gates of the hell that's opened to swallow me up."

"You mean the care of the boy and An-ina?"

"Till I get back. Then you'll hand 'em over without—a kick."

Ross ran his great fingers through his hair, while he sought the last glow of sunset for inspiration.

"It's a hell of a country—up there," he protested, after a moment. He was thinking of the child. He was thinking of Millie's possible protests at sacrificing the child to the terrors of Unaga.

"He was bred there." Steve's eyes were urgent. "It's handing to him the things his father would have wanted him to have. Think, Doc. By every moral right the 'Adresol' secret is his. It cost him a father. It cost him a mother. It would have cost him his life—a white man's life—if it hadn't been for the hand of Providence sending me along to him. Besides, it's all here, Doc," he went on tapping his breast. "He's been my anchor, my small, little anchor, but a mighty powerful one. He's saved me from all sorts of hell, and I want to hand him the life he's saved in return. I want to raise him to a great manhood, and hand him a future that'll stagger half the world. And if I fail I'll have done all a mortal man can."

The rustle of a woman's dress in the hallway behind them heralded Millie's approach. Ross stood up hastily. He was just a shade relieved at the interruption. In a moment the atmosphere was changed from Steve's passionate urgency to the domestic lightness of a happy wife's presence.

"Why, Mac," she cried, as she stood framed in the doorway, "you two boys still doping yourselves with smudge and tobacco smoke? That kiddie's only just gone off to sleep. He's a terrible tyrant, Steve, and just the sweetest ever."

She glanced quickly from one to the other, and in a moment the smile died out of her eyes in response to the seriousness she beheld in the faces confronting her.
