"I know an ugly little creek running into Big Wolf that's the dickens to cross. I'll run clear round it, even if it takes longer. After all, I'm doing just what I said I wouldn't do. I don't know why I didn't go on, nor why I am tacking off up here. Something tells me to do it, and I'll do it." But however changeable of mind he seemed to himself, Dr. Carey was a man who formed his judgments so quickly and acted upon them so promptly that he seemed most stable to other men. He rode forward now to a land wave that dropped on one side to a creek, a quarter of a mile away, where black shrubbery marked the water line. A long swell of wind swung down the valley, whirling the snow in eddies before it. As the doctor's eye followed them, he suddenly noted a red scarf lift above the tallest clumps of bushes and flutter out to its full length, then drop again as the wind swell passed. "There's nobody in fifteen miles of here. I reckon that scarf blew there and caught some time this fall when somebody was going out on the trail. Mighty human looking thing, though. It seemed waving a signal to me. But I must hurry on." He hastened at a gallop up the ridge away from the creek, his mind still on that red scarf flung about by the winter wind. "It was a strange thing," he thought, "but every human token is startling out here. What's that now?" The doctor had a plainsman's ear as well as a plainsman's eye. As he listened, through the wail of the wind borne along the distance, he caught the words of a song, low and pleading like a plaintive cry for help: Though, like the wanderer, The sun gone down, Darkness be over me, My rest a stone-- Yet in my dreams I'd be Nearer, my God, to thee, Nearer to thee. It was a woman's voice and Carey faced about to listen. He knew it came from the bushes below the red scarf. So he changed his course and hurried around a bend in the stream to the other side of the brush where Virginia Aydelot stood beside Juno. "I'm afraid there isn't even a stone to rest on here, Madam. Can I be of any service to you?" he said, lifting his hand toward his cap in semi-military salute. Virginia stood looking at the stranger with a half-comprehending gaze. She had been less than an hour beside the bushes, but it had seemed to her like many hours. And the terrifying certainty of a night alone on the prairie made the sudden presence of a human being unreal to her. "I beg your pardon; I am Dr. Carey, of Carey's Crossing, and I was striking across the prairie to the Big Wolf settlement when I saw your scarf and heard your singing. I took them both to be distress signals and came over to see if you needed me." One had only to listen to Dr. Carey's voice to understand why Darley Champers should accuse him of laying a charm on the whole settlement.
