hild that the Tree-dwellers did not have such music as
we have. But mothers as they held their babies in their arms would
gently sway back and forth, uttering a soothing sound. The little girls
will no doubt enjoy making such a lullaby in their hours of play.

_Lesson VII._ If no child in the class knows what kind of banks a river
has at the drinking-places, and if there is no opportunity to go to a
brook or river to find out, do not state that the banks are low. The
fact presented in that way would be almost devoid of meaning. But let
the child model a river valley in the sand box or out on the playground
showing steep banks in places and in others banks that slope gently.
Then let him think of a herd of cattle feeding on the hillsides. The
cattle need water. Suppose that they come up to the steep banks. Can
they reach the water? How can the cattle get down to the stream? When
the cattle have found a good drinking-place will they be apt to come to
it again? By means of such questions as these the child can picture the
conditions and the relation of living creatures to them. Such knowledge
as this means something to him. He need not try to remember it, for it
is his.

Give the child plenty of time in reading the short sentences that
picture the cattle in the stream to allow him to actually see the
different steps in the process. By considering each point by itself, but
yet in relation to the preceding step, the child can get a vivid
picture. (For information concerning the wild cattle, see _The Urus_,
p. 145.)

_Lesson VIII._ This lesson is introduced to give the child a faint
suggestion of the struggle for existence among wild animals. It also
suggests something of the dangers to which the Tree-dwellers were
exposed. Pass lightly over these dark pictures and emphasize the fact
that it was possible even in those times for Sharptooth and her baby to
sleep safe from harm. In contrast to this wild life let the children
draw pictures that will illustrate the security and comfort of their own
homes.

_Lesson IX._ If possible let the child visit a cave; if not, he may take
advantage of the tiny streams that may be seen everywhere after a heavy
rain or during the thawing of snow. A careful examination of such a
miniature stream will enable the child to get all the experience he
needs in order to understand the geographical phase of this lesson.

Do not try to teach the child much more than he can observe regarding
the wa
