"For my sake only?" I asked. "For all our sakes," she replied. But she blushed a little, despite the anxiety which was foremost in her mind. We passed up the defile, and then our party spread out like a fan. I was convinced that the colonel could not have gone far. The snow was an added obstacle to the naturally difficult character of the mountains. It was still pouring down, half blinding us, and compelling us to scrutinize every inch of the way lest the loosening drifts should carry us in an avalanche to the bottom of some precipice, which would be highly disagreeable. CHAPTER VIII. THE RESULTS OF A SNOW-SLIDE. Dr. Ambrose and I stuck together, picking our way through the storm. Snow-covered mountains under an angry sky are not a cheerful prospect, and the work was fearfully tiresome. Down my boot would crush under my weight through a foot of snow, and to lift it out again was like drawing a wedge from a log. It was winter, but I grew hot, and my brow produced sweat. My breath shortened, and my muscles said they were tired. The doctor noticed me. "You'd better go back, Mr. West," he said. "This is very exhausting business for one who is not used to it." But I was a bit ashamed of playing out so soon, and insisted upon going on. He said nothing then, but when he raised the question a half-hour later I was forced to confess that he was right. A tuckered-out man was of no use on such a trail. "You'd better go straight back to the camp, and I've no doubt you'll find one or two there who played out before you did," he said. Leaving him regretfully, I faced about and began to plough my way through the snow on the return journey. I had noted the landmarks well, and recognized them easily. The snow, still falling, had buried all trace of our footsteps under two or three inches of white. I tugged along with a fair degree of patience, wishing at the same time that I was back at the camp, drying my boots and drinking a hot toddy,--unpicturesque but pleasant occupations. But walking beat wishing, and at last I saw the smoke of our camp-fire over a hill. I increased my speed, trying to make a run through the deep snow. I passed near the edge of a cliff, but no nearer than we had gone when we started on the search. I forgot that the snow had grown deeper and more weight was pressing down upon the slopes. When I was nearest the edge the snow seemed to slip from under my feet; the mountain tilted up at a new angle; there was the rumble of tons of snow sliding over the steeps, and away it went in a huge white avalanche, bearing me, who had started it, upon its crest, sick with sudden fear.
