The floor of the snow house is the bed of snow from which the building material was taken. The door is cut by taking blocks of snow from under the bottom row of the foundation blocks. A trench is made, and along the side of it the blocks are placed. An arched covering of the material forms a sheltered passageway to the door. When the snow house is to be occupied for a considerable time the doorway may have walls of snow blocks piled as high as the shoulders, with the top left open. This shields the entrance from wind and drifting snow. Various forms of entrance are constructed, often very tortuous; and when made a refuge by the numerous dogs they are not pleasant paths along which to creep on hands and knees, for a panic may seize some cowardly canine and all the dogs struggle to get suddenly out into the open air. Vicious animals often wait until a white man gets about half way through the entry and then make a sudden assault on him. The interior of the house is arranged according to the number of persons inhabiting it. A raised bed, on which to sit during the day and sleep during the night, is formed either by leaving a part of the snow-bank or else by bringing in blocks and arranging them as a solid mass. On this are spread bows of spruce, or dry grass, if obtainable, otherwise fine twigs of willow or alder, and over these heavy reindeer or bear skins are thrown. On these bed-skins are laid other softer skins of reindeer, with which to cover the person on retiring to sleep. A window is sometimes set in the side of the structure toward the sun. This is simply a piece of thick, clear ice, from a lake, set in the wall of the dome. It admits light, although it is generally light enough during the day within the snow-house unless the walls be built particularly thick, but great thickness in certain situations becomes necessary lest the winds and drifting snow wear away the sides of the structure, causing it to admit the cold or tumble down. Around the outside of the hut is sometimes built a protecting wall of snow blocks, two or three feet high, to prevent the drifting snow from wearing away the side of the dwelling. A storm of a single night’s duration is often sufficient to destroy a house. The interior walls, in severe weather, become coated with frost films from the breath, etc., condensing and crystallizing on the inside of the dome and often presenting by the lamplight a brilliant show of myriads of reflecting surfaces scintillating with greater luster than skillfully set gems. If the roof is not carefully shaped it is liable to cave in from the heat within softening the snow, especially in moderate weather, and then the entire structure falls.
