were
terribly frightened. They turned and ran for the trees, leaving the
wounded man on the ground.

Hawk-Eye ran out from behind the rock, picked up his spear, and sent it
flying after the enemy. It struck another man. Howling with pain and
fear, he too dropped in his tracks. His companions ran faster than
ever, and when they reached the trees, instantly swung themselves up by
the branches and disappeared. Only now and then one could be seen
swinging from tree to tree, back into the deep forest, like great
monkeys. Hawk-Eye again ran after his spear. This time he pulled it
out of the wounded man's flesh himself, and left him rolling on the
ground, too much hurt to attack him or defend himself. Then Hawk-Eye
ran back to the little group hidden behind the rock.

Everything was now as quiet as if no one lived in the forest at all.
There was not a single tree-dweller in sight except the first wounded
man, and he was already crawling as fast as he could up the bluff.

In spite of everything, Hawk-Eye and Limberleg had held on to their
meat, and now they felt the need of food. They cut Limberleg's load
into four great chunks, and each took one. They ate as they walked.
They ran along past the place where the mammoths were feeding and then
turned their backs on the river and plunged into the deep forest toward
the east. The ground began to rise a little, and Hawk-Eye said, "If we
keep on climbing in the direction of the rising sun, we are bound to
reach the blue hills at last."

All that day they journeyed, and that night they spent in a tree. The
next morning found them still climbing. At last, about noon of the
second day, they reached the crest of the range and climbed out upon the
high, bald summit of the highest hill.

No one of their clan had ever been so far from the cave, and no one of
them had ever seen what Hawk-Eye and Limberleg and the Twins now saw.
There was the world spread out before them! They looked back far away
in the blue distance toward the west, and there they saw a little silver
thread. That silver thread was their river. They looked toward the
south, and far, far away they saw more water than they had ever dreamed
there was in the whole earth. They didn't know what it was. They were
not even sure that it was water. They had never heard of the sea. They
stood silent and breathless with wonder and gazed at it. At last
Hawk-Eye said in an awestruck tone, "It's the end of the w
