There were no stores then.
She could not buy food of a farmer.
There were no farmers then.
All the plants were growing wild.
All the animals were wild, too.
Sharptooth was afraid of them.
That is why she climbed the trees.

THINGS TO THINK ABOUT

Did you find a place where the Tree-dwellers might have lived?
What kind of a place was it?
Did you find any wild foods where the ground was covered with grass?
Do you think they could live on a grassy plain?
Did you find any wild foods where the trees were thick?
Do you think they could live in a dense forest?

Can you think of a name for the place where the Tree-dwellers lived?

They needed to be near fresh water.
So they lived by trees along the river.
They needed to be where they could find roots and berries.

[Illustration: "_The wooded hills_"]

Down in the river valley most of the forests were dense.
The sun could not shine through the thick leaves of the trees.
There was not enough sunlight to make the roots and berries grow.

So the Tree-dwellers could not live there.

[Illustration: _Acorns_]

Out on the grassy plains there were no trees.
The Tree-dwellers could not live there.
Near the head of the river valley there were hills and uplands.
The forests there were not so dense.
The sun could shine through the open spaces.
Many roots and berries grew there.
