It would astonish a civilized spectator to see how many people can be stowed away to sleep in one small igloo and under one blanket; but the proverbial illustration of a box of sardines would almost represent a skirmish line in comparison. Each one is rolled up into a little ball, or else arms, legs and bodies are so inextricably interwoven, that it would be impossible for any but the owners to unravel them. And these bodies are like so many little ovens, so that, no matter how cold it be, when once within the igloo, the snow-block door put up and chinked, and all stowed away in bed, Jack Frost can be successfully defied. As probably many people know, an igloo is usually built of snow. The word, however, means house, and as their houses consist of a single room, it also means room. Sometimes at points that are regularly occupied during the winter months igloos are built of stones, and moss piled up around and over them, so that when covered by the winter snows they make very comfortable dwellings. This is the case at Igloolik, which means the place of igloos, and also near Tulloch Point, on King William Land, where the ruins of these underground houses were quite numerous. They had been built a great many years ago by the Ookjooliks, when they occupied the land before the Netchillik invasion. A long, low passage-way leads into each dwelling, so constructed as to exclude the wind from the interior, though ventilation is permitted by leaving open the door. This, by the way, is an Inuit custom. Even in the coldest weather the door is open, except when the occupants are asleep, and it is only closed then to keep the dogs from making a raid on the igloo. If the door faces the wind, a shelter is erected outside to cut off the wind, so that the door need not be closed. The coldest day I ever saw, when the thermometer was seventy-one degrees below zero, the door of our igloo was open all the time we were not asleep. A snow igloo is made of snow-blocks about three feet long by eighteen inches wide and five or six inches thick. [Illustration: SECTION AND PLAN OF ESQUIMAU HUT.]
