As it grew colder the light tent no longer offered adequate protection. The women sewed a new cover of sealskins and gathered loads of brush. They placed them on the outside of the summer tent, and spread the new covers over the whole structure. The door flap was also transformed into a solid wall, and only a low opening was left, through which the people had to pass, stooping down low. This darkened the inside of the tent, which before had been fairly light because the front part of the tent cover was made of the transparent inner membrane of sealskin. Therefore the lamps were put into place. The long, rectangular entrance of the tent with its roof-shaped cover still served for keeping provisions, but just in front of the beds, the soapstone lamps—long crescent-shaped vessels—were placed. The wife of the tent owner took her seat on the bed in front of the lamp, where she sat in kneeling position letting her body rest between her heels. The lamp was filled with blubber that had been chewed to release the oil, and the straight front edge of the lamp was provided with a wick of moss which, when carefully treated with the bone pointer, gave an even, yellow flame that lighted and heated the hut pleasantly.
