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.
Macintosh Sack.--Mr. Falconer writes to me as follows:--"I travelled in
1841 from Austin in Texas to Mexico through New Mexico.
