 at the time, the igloo was so cold that we 

 all had to go to bed under the thick rein-

 burning candle near the wall of snow on 

 the side from which the gale was coming, 

 the flame was bent over nearly one-third 

 or half way toward the center of the 

 igloo. 



If the igloo becomes very warm inside 

 by the lamp's using up too much of the 

 air, the heat ascends to the top and soon 

 cuts its way through the soft snow in the 

 chinks of the snow-blocks, and these 

 little chimneys soon afford a sufficient 

 amount of fresh air. If they give too 

 much, they are " chinked up " with a 

 handful of snow taken from the front of 

 the snow bed.
