owl.
The rhinoceros turned fiercely upon them.
He tossed one of the hyenas over the cliff.
As he did this he lost his footing.
The huge creature stumbled and fell.

[Illustration: "_He tossed one of the hyenas over the cliff_"]

He rolled down the steep cliff and was dashed upon the rocks.
The hyenas were no longer afraid.
They feasted upon the carcass.
They dragged the bones to their caves.
They gnawed them until they left the marks of their teeth.
The bones stayed in the caves for many years.
Not long ago some one found them there.
He sent them to a museum, where they may be seen to-day.
Perhaps you will go to the museum some time.
If you do, be sure and look at these bones.
Perhaps you will be able to help your friends read the story they
tell.

THINGS TO DO

_Think of the rhinoceros as he was rooting up the tree._
_Think of him as he was tearing the wood into strips._
_Draw one of the pictures._
_Think of the high cliff with the caves at its foot._
_Model the cliff and caves in your sand box._

THINGS TO THINK ABOUT

Can you think how a fire might have been started before people knew
how to make it?
What did the Tree-dwellers think the fire was?

_Frightened by Fire_

One day there was a great storm on the wooded hills.
The lightning struck a tree in the forest.
It set it on fire.
At once the flames spread to the neighboring trees.
The Tree-dwellers were driven to the ground.
They had never been so frightened before.
They were afraid of thunder and lightning.
They were afraid of beasts of prey.
Only when they were up in a tree did they feel that they were safe.
But now the trees were on fire.
They thought that the fire was a wild animal.
They thought that it was an animal that ate wood.
They had seen the rhinoceros and the mammoth eat parts of trees, but
this creature devoured all the trees in its path.

Several years passed by.
Once again a fire broke out on the wooded hills.
Once again the wild animals ran.
The Tree-dwellers ran, for they still were afraid.
Bodo ran; for he, too, was afraid.
But he soon stopped and looked at the fire.

[Illustration: "_Bodo stood and watched it a moment_"]

He was almost full grown now.
He was learning every day.
He was curious about many things, and now he wanted to se
