"My grandfather told me," said Flint, as he walked slowly down the
hill, "that in the old days the cave men did not have stone axes and
spears. They hunted with sticks; they threw a stick like your mother's
digging stick; and they struck with a stick like your father's hunting
club. And they used the sharp stones they chipped only for knives and
scrapers. But one day, a man thought about tying a sharp stone to a
stick! There, you see, was the first spear!"

"That was a great day for the cave men!" Flint went on, while his grim
face lighted up. "For with a stone weapon they could hunt the swift
wild animals, and so get more food."

Then he stamped his foot and said, "And they could kill enemies
better!" And he clenched his fist, while his face grew hard.

The next day, men from the stone yard went out to make a fish trap.
They drove sticks across the river bed where the water was low. Then
from stick to stick they tied string made of skin. Rushes grew by the
river. They took these and wove them in and out of the strings until
the trap reached clear across the river. The water could go through
the rushes, but the fish could not; and the men speared them or caught
them with their hands.
