e described," writes Mr. Nadaillac,
"but for the care and nursing of those around him, such as the other
members of his tribe. The wounded one must have been fed by the others
for months; nay more, he must have been carried in migrations, and his
food and resting place must have been prepared for him."

_Lesson XXVII._ There was little difference between weapons and tools
until the period of the later Cave-men. A piece of chipped stone
served as a tool and a weapon. The children learned when they read
_The Tree-dwellers_ how people used the tools in their bodies and how
they supplemented these by the use of natural tools, such as sticks,
stones, shells, bones, and horns. In reading _The Early Cave-men_ they
learned how people chipped flint and bound strong handles to heavy
spear points and axes. At this time they can learn how people came to
make use of new materials--materials which require the use of _tools_
in shaping into weapons. Tools had been used by women from a very
early time. The digging-stick, the hammer-stone, the chopper, the
knife, and the bone awl are tools which every woman used. Men, on the
contrary, were more interested in weapons than in tools, and it is
quite likely that the first steps which led to the differentiation of
tools from weapons was made by a man who had been wounded and thus
disabled for the hunt.

The incident of Bighorn making fun of the bone dagger is introduced
to illustrate the conservative tendency which is still present in
society, a tendency less powerful now than in early times, yet strong
enough to keep many people out of sympathy with the forces which work
for progress.

Let the children examine a real antler, if possible, and notice its
fitness for being made into a variety of tools and weapons. If no
antler can be found let them examine the picture of one, so as to
determine what part of it is used in making a dagger, a hammer, a
baton, a tent peg, and an awl.

_Lesson XXVIII._ The invention of the flint saw marks an important
step in the evolution of both tools and weapons. Without the saw it
would have been impossible to use such material as bone, horn, and
ivory. It is interesting to notice that the saw was at first not
clearly differentiated from the file and the knife, the three tools
being united in one piece of flint.

_Lesson XXIX._ In representing the action of a story by means of
pantomime, let the children choose a leader who shall take charge
of the actio
