man's inventions and the animal's habits. A new invention which gives
man greater power in hunting, makes the animals more timid, more
watchful, more skillful in escaping from man's presence. Hence, man
is constantly stimulated to make new inventions, in order to be
successful in the hunt.

_Lesson XXII._ No animal was more difficult to hunt than the wild
horse. Herds of horses were organized under a leader and sentinels
which were very alert in detecting the least sign of danger; and as
soon as the alarm was given, the herds would run with great speed
until they were out of sight. When unable to escape they would fight
furiously with hoofs and teeth. When in need of a new pasture,
scouts--the old, experienced, wise, cautious, and observant members of
the herd--would be sent out to search for good feeding grounds and to
report to the herd.

_Lesson XXIII._ Help the children to see that, although the children
of the caves did not go to such schools as we have, they had lessons
to learn and tests to take. Those who lived together had to learn
to work together. Each one must learn to be patient, brave, and
self-controlled. The thoughtless, impatient, and cowardly were apt to
prevent the capture of wild animals in the hunt, and to risk the lives
of their clansmen. Hence, from early childhood the old men and women
gave attention to teaching the children, preparing them for the tests
which must be passed before they ranked with the men and women.

_Lesson XXIV._ Instances of stags meeting death by having their horns
interlocked are well known.

_Lesson XXV._ Encourage the children to notice the difference between
those animals which live in herds and those which lead a solitary
life. Although the dog has changed greatly since it was domesticated,
a study of the dog will be helpful in understanding the habits of
packs of wolves. Jack London's _Call of the Wild_, and Ernest Thompson
Seton's stories will be helpful in this connection. The cat, having
changed less than the dog, will furnish the child with a good type of
carnivorous animals that lead a solitary life.

_Lesson XXVI._ From an examination of the skeletons which have been
referred to the late Pleistocene period, it is evident that the
Cave-men were able to treat wounds and to set bones. "No one could
have survived such wounds as we hav
