"We're not climbing for money now," Andrew grimly reminded him. "There's food ahead of us and we must get on!" They made the ascent, though it tried their nerve severely. When they finally crawled up to the summit Andrew stopped, growing suddenly white in the face. "Look!" he said hoarsely. Carnally sat down heavily in the snow. "A dead tree! Nobody put it there; it grew!" With an effort he pulled himself together. "Come! We'll try farther on!" CHAPTER XVIII THE EMPTY FLOUR-BAG When it was getting dark Andrew and Carnally gave up the useless search. A red glow, flickering among the spruce trunks, guided them down the pass, and they saw Graham's figure, black against the firelight, as they approached the camp. He was standing up, looking out for them, but they came on in silence and after a quick glance at their faces he turned away and busied himself getting supper. He knew they had failed and words were superfluous. They ate the small bannock he took from the frying-pan, and Andrew glanced about the camp when he had lighted his pipe. Graham had been at work while they were away, laying down spruce branches and raising a wall to keep off the wind. It was warm beside the fire, and the place looked comfortable. "There wouldn't be much to complain of if we had enough to eat," said Andrew. "It's surprising how soon one gets grateful for such a shelter as this, and I believe I've slept as soundly in the snow as I ever did in bed." "I tried to fix things neatly, though I wouldn't have been sorry if I'd wasted my labor," Graham replied and glanced at Carnally. "It struck me we might be here a day or two." Carnally's smile was rather grim. "It's very likely. S'pose I ought to play up to Allinson, but he's put it a notch too high. I've been doing some hard thinking while I was on the hill. We're certainly up against a tough proposition." "You're still convinced the grub is here?" "That is a sure thing--all we have to do is to find it; but it's going to be a big job. I expect both of you want me to talk?" Their willingness to hear his views was obvious. "The trouble is," he explained, "you can get down from the neck a number of different ways--there are the spurs one could break a trail along and there are the ravines. We may try them all before we strike the right one; but we'll have a better chance if we work up instead of down." "Why?" Andrew asked. "Because the packers would start from the low ground, and the benches look different from below." "Do you think Mappin told them to pick any particular place?" "I've been figuring on that. He's learned something about the ground, and my idea is that the provisions are dumped in a hollow that looks like a good road up to the gap; that is, as you would see it from the creek. What we don't know is where his boys would strike the ice. It might be anywhere within three or four miles." Andrew knit his brows.
