The cold is intense, the spirit thermometer indicating from thirty to sixty below zero. We have seen the mercury frozen as solid as lead for weeks together. For months milk is frozen into cakes like marble. We used to carry large pieces of it wrapped up in a newspaper, and when at the camp-fire we desired a little in our cup of tea, we cut it off with an axe. As will be seen from this we had about seven months of bright cold winter. During all that time there was not a thaw, the snow was never soft, and there was no dampness in the air or under foot. Soft deer skin moccasins are very much superior to civilised boots or shoes under such conditions. There are no roads in that vast country. The frost King freezes up every lake and stream, and hardens into adamant every muskeg and quaking bog. The snow covers everything with its great mantle of beauty, and makes it possible to travel on snow-shoes or by dog-train through vast regions absolutely impassable in the summer months. Horses or other large animals, are absolutely worthless for travel in such regions. The snow is a great leveller. It fills up many a dangerous pitfall and puts such a cushion on the logs and rocks, that upsets or falls are only laughed at by the dog-travellers as they merrily dash along. The only drawbacks to a tumble down a steep declivity of some hundreds of feet, as once befell the writer, were the laughter of his comrades, and the delay incident to digging him out of the snowdrift at the bottom, which was anywhere from twenty to thirty feet deep. These accidents and delays were not frequent; and, although there were hardships and sufferings, there were many things to instruct and interest, and to break the monotony of winter travelling in that lonely land. In the coldest, brightest, sunniest days, the fitful mirage played its strange antics with distant landscapes, and at times brought within near vision places many miles away. Sometimes circle within circle appeared around the sun, until as many as four were distinctly visible; each circle at times having within it four mock suns--sixteen mock suns visible at the same time was a sight worth going a long distance to see. Strange to say, the Indians dreaded the sight of them, as they declared they were always the forerunners of blizzard storms; and the more vivid these sun-dogs, as they called them, the more dreadful would be the storm.
