"The sun'll be up in a few minutes," said the old man. "We must turn back now."
"Just one more moment," pleaded the woman.
"The sun will catch us."
"Let it catch me then!"
"You don't mean that."
"I mean nothing, nothing at all," cried the woman.
The sun was coming fast. The green in the valley burnt away. Searing wind blasted from over the cliffs. Far away where sun bolts hammered battlements of cliff, the huge stone faces shook their contents; those avalanches not already powdered down, were now released and fell like mantles.
"Dark!" shouted the father. The girl sprang over the warm floor of the valley, answering, her hair a black flag behind her. Hands full of green fruits, she joined them.
The sun rimmed the horizon with flame, the air convulsed dangerously with it, and whistled.
The cave people bolted, shouting, picking up their fallen children, bearing vast loads of fruit and grass with them back to their deep hideouts. In moments the valley was bare. Except for one small child someone had forgotten. He was running far out on the flatness, but he was not strong enough, and the engulfing heat was drifting down from the cliffs even as he was half across the valley.
