Heat makes motion, and motion makes heat. And both heat and motion are from the sun.
STORIES FROM ZOOLOGY
THE OWL AND THE HARE
It was dusk. The owls began to fly through the forest to find some prey.
A large hare leaped out on a clearing and began to smooth out his fur. An old owl looked at the hare, and seated himself on a branch; but a young owl said to him:
"Why do you not catch the hare?"
The old owl said:
"He is too much for me: if I get caught in him, he will drag me into the woods."
