In fig. 1 the wide opening to the mouth of the bag is shown; also the ends of the buckles and straps that are sewn (on patches of leather, for additional strength) to the lower side of the bag, as seen in fig. 2.
[Fig 1 and 2].
It must be understood that the woolly sides of the skins are inwards. The straps that hold the knapsack to the shoulders are secured by a simple fastening, shown in figs. 2 and 3. But the ordinary knapsack hooks and rings, if procurable, would answer the purpose better. The straight lines in fig. 1 show the way in which the bag is to be folded into the shape of fig. 3. Fig. 4 shows the sleeper inside his bag, in which he fits very like a grub in its cocoon. There is no waste of space. For the sake of warmth, the bag is made double from the knees downwards, and also opposite to the small of the back.
[Figs 3 and 4].
During the daytime, when the weather is wet or cold, the bags are of much use, for the douaniers sit with them pulled up to their waist. When carried in the manner of a knapsack the bag sits perfectly well against the shoulders; but, owing to the yielding nature of its substance, it lies too close to the back, and is decidedly oppressive. A wicker frame might well be interposed.
Arctic Sleeping-bags.—Arctic travellers use coarse drugget bags, covered with brown holland to make them less pervious to the wind, and having a long flap at the upper end to fold down over the face. I have already extracted passages from travellers’ accounts relating to them, in speaking of “Encamping on Snow,” p. 140, and another, when speaking of “Snow-walls with Tenting for their Roofs,” p. 143.
