g the edge of the flake. He
pressed very hard; and every time he pressed, a little chip flew off.
He worked very fast.

"I must not let a hump come in the middle," he said; "for then I should
have a turtle back. Look on that chip pile; you will see many turtle
backs that I have thrown away."

The old man was making the point now, and he began to sing:

"I give you the eye of the eagle,
To find the rabbit's heart!
I give you the eye of the eagle,
To find the rabbit's heart!"

As Thorn listened, and caught the meaning of the song, his eyes grew
bright and he held his head high.

"Grandfather hopes that I will hunt with the little bow and spear!" he
said to himself.

He was very glad. He began to dance and clap his hands in time with
the old man's song. Then he caught the words and began to sing with
his grandfather:

"I give you the eye of the eagle,
To find the rabbit's heart!
I give you the eye of the eagle,
To find the rabbit's heart!"

Before long the little spear head was done. It was thin and sharp and
beautiful. Thorn tied it to the little straight stick, and he had an
arrow for his bow!

Flint worked on.

"We make all of our axes and spear heads and knives and scrapers of
flint," he said after a while. "It chips more easily than any other
stone."

After some time Flint and the boy left the stone yard.

CHAPTER IX

AT THE GRAVEL PIT

As they walked along, the old man pointed to a place in the hillside
and said, "That is the gravel bed. From it we dig all the stone for
our axes and spear heads."

Thorn looked and saw a big hollow in a gravel hill. The hill was made
of sand and clay and pebbles and bowlders. The rain had washed some of
the sand and clay away, and the stones had fallen down and now lay in
piles on the ground.

"Men come from far away for our stone," the old man went on. "It is
good stone for axes. They bring us shells and amber and meat and skins
for our stone. Some of them take the stone to their homes and make
their own axes; others buy our axes."

At the gravel bed, men were at work. One man had a big digging stick.
He put it under a rock and pushed it out of the ground. Another man
had the shoulder bone of a bear. He pushed it under some pebbles and
lifted them and threw them upon an ox skin on the ground. Then he
gathered up the corners of the skin, took it on his back, and carried
it do
