ference between tomahawk shacks and axe houses reminds me of the
difference between the ileum and the jejunum, of which my classmate once
said: "There is no way of telling the beginning of one or the ending of
t'other 'cept by the pale-pinkish hue of the latter."

It must be confessed that some of the shacks described in the preceding
pages are rather stout and massive to be classed as tomahawk shelters,
but, as indicated by my reference to physiology, this is not the writer's
fault. The trouble is owing to the fact that nature abhors the arbitrary
division line which man loves to make for his own convenience. The
tomahawk shacks gradually evolve into axe camps and houses and "there is
no telling the beginning of one and the end of t'other." Hence, when I say
that all the previous shacks, sheds, shelters, and shanties are fashioned
with a hatchet, the statement must be accepted as true only so far as _it
is_ possible to build them without an axe; but in looking over the diagram
it is evident at a glance that the logs are growing so thick that the
necessity of the woodman's axe is more and more apparent; nevertheless,
the accompanying caches have been classed with the tomahawk group and we
will allow them to remain there.

Wherever man travels in the wilderness he finds it necessary to
cache--that is, hide or secure some of his goods or provisions. The
security of these caches (Figs. 98-111) is considered sacred in the wilds
and they are not disturbed by savages or whites; but bears, foxes, husky
dogs, porcupines, and wolverenes are devoid of any conscientious scruples
and unless the cache is absolutely secure they will raid it.

[Illustration: Simple forms of caches.]

The first cache (Fig. 98) is called the "prospector's cache" and consists
simply of a stick lashed to two trees and another long pole laid across
this to which the goods are hung, swinging beneath like a hammock. This
cache is hung high enough to be out of reach of a standing bear.

The tripod cache (Fig. 100) consists of three poles lashed at the top with
the goods hung underneath.

Another form of the prospector's cache is shown by Fig. 102, where two
poles are used in place of one and an open platform of sticks laid across
the poles; the goods are placed upon the platform.

The tenderfoot's cache (Fig. 105) is one used only for temporary purposes
as it is too easily
