"How far?" he demanded.

"Two days' journey, maybe seventy-five miles."

"You wait for the boy in the shelter of the poplar bluff across the coulée," he said. "When the snow stops, follow on as well as you can."

"Charley not come any more," said Rina in a tone of quiet fatalism. "When snow hide our track, he walk round and round. Bam-by he fall down, and not get up. He die. He know that."

Garth, ready to push into the storm, reined up again. Her sureness chilled his impatient hurry; and the oft-told tragedies of prairie snowstorms recurred to him.

"Die in the snow!" he repeated dully, hanging in agonizing indecision between the two images; Natalie ahead, and the solitary boy plodding behind. On the one hand he thought: "The storm has held them up, somewhere just ahead! It is my only chance of overtaking them!" and then he turned his horse's head north. But the other thought would not down. "The kid knew it meant death to walk; and he chose it!" Garth finally led the way back over the coulée.

Rina had no difficulty making herself comfortable among the young poplar trees. She improvised a shelter out of a blanket stretched over two inclined saplings; and in front of it she built a fire. Garth meanwhile changed to the fresher horse, and started back over their own dimming trail.

"You never find him now," Rina said hopelessly, as he left her.

Garth merely set his jaw.

His watch told him it was past eleven. He calculated they had covered five miles between the two coulées, and that it would be about twenty-five miles all told back to their own camping-place. Supposing the boy to have averaged three miles an hour, he would now be some twelve miles away, and if he kept walking, Garth, at his present pace, should come upon him in an hour and a half's riding.
