“I’m coming with you to the foot of the Swift Current switchbacks,” said Joe. “I got to know whether you get up to the top safe!”

“But the Ranger?”

“I can’t help him much if I stay—and I guess he’s in no more danger than you’ll be. Oh, Spider, I got to know if you get up there safe!”

Poor Joe was close to anxious tears as he spoke, and Tom grasped his hand.

“I’ll get there!” he cried.

Mills was now only half conscious, moaning on his bed, and the two boys slipped out into the starlight and pushed up the Swift Current trail. It was bitterly cold. Joe carried the pack all the way to the foot of the switchbacks, so that Tom could be as fresh as possible. Then, at the foot, as day was beginning to redden in the east and give light enough to follow the windings of the trail by, for, on this steep slope, even such a deep snow could not quite hide the cuts the trail made in the bank, the two scouts shook hands silently, and Tom started up.

“It’s Mills’ life, or mine,” he said, grimly.

Joe watched him go up, slowly, carefully, following the trail wherever he could detect it by the contour of the snow. Two or three times his snow-shoes started a small slide of loose snow, but as he was above the starting point, it left him secure, rushing down past Joe with a whirl and shower of snow powder. But on this slope, steep as it was, the tiny trees and shrubs seemed to anchor the snow, and there were no large slides at all. After an hour, from far above him, Joe heard a faint, thin, “Hoo-oo!” and knew that Tom was beyond danger.

His heart seemed to come back into his breast again, and with a great sigh of relief he hurried back in the level sunrise light, to the cabin, to do what he could for the sufferer.

There followed for Joe a long vigil, almost helpless, with a very sick man. He gave him hot water to drink, and improvised a hot water bag with a hot stone wrapped in flannel, but he had no medicines, and could do little but watch the poor Ranger suffer, and wonder, and wonder, how Tom was getting on, until a great, dark, ugly cloud suddenly began to come over the top of the Divide, from the west, and his wonder changed to fear and then almost to terror. It looked as if the worst blizzard of all was raging already on the west side of the range, where Tom was tracking, all alone, miles from any human being, in the deep forests of the cañon!
