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,

swer 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.

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 Sleepiiig-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 " Snowwalls with Tenting for their Roofs," p.143.
