orld."

"Let's go to the very edge and look over it," said Limberleg. "Maybe we
can find out where the sun hides during the darkness."

You see what a brave woman she was.

"Then are these the blue hills?" asked Firetop. "They don't look blue a
bit."

"The blueness is all around us, though," cried Firefly, pointing down
into the valley. "And beyond the end of the world, it's all blue too,
with sparkles on it! And the sky is blue. The only place that isn't
blue is right around us."

"We will surely go through the blue country to get to the end of the
world then," said Firetop.

All this time Hawk-Eye had been standing on the highest point, studying
the view and choosing landmarks. He knew how to find his way through
forests as well as we know the way to the post-office. When he had the
route all planned out, he called the children and Limberleg to his side.
He pointed to the south. "Do you see far away that little neck of land
which leads out to the very end of the world?" he said. "We will keep
the sun on this side of us the first half of the day and on the other
side the other half of the day and we shall surely reach it. Then we
shall see what lies beyond."

Hawk-Eye led the way over the crest of the hill and down into the forest
below, the Twins and Limberleg close behind him. All day they pressed
on, over hills, through dense woods, and across little streams, keeping
always to the south. At last they found the narrow neck of land which
they had seen from the hill-top. They camped that night in a tree, near
the water's edge, and, at night-fall of the second day after, they
climbed the last weary mile and stood upon the great rocks at the end of
the world.

A stream of fresh water poured through a deep gorge beside them.

Toward the east and toward the west, farther than their eyes could see,
stretched the dark blue waters. Toward the north they could look clear
across the island to the distant shore of the mainland. We know now
that they stood on the southern coast of the Isle of Wight, and that the
faint blue line across the water would some day be called France. But
the Twins and their father and mother thought that they stood on the
very edge of the earth and looked out into mysterious regions which lay
beyond.

As they stood gazing, the western sky flamed with red and gold and the
sun sank out of sight behind a distant point of land. High up in the
east the pale round disk of the m
