They were becoming more and more like tigers, and they went to hunt the wild horses.
The timid horses ran when their enemies came, for there was no place in which to hide.
When they ran they stepped on the tips of their toes.
They used the third toe so much more than the others that it became larger and larger.
Its hoof became hard and strong.
The first and fifth toes were used so little that after thousands of years they disappeared.
Meanwhile the horses had learned to run fast.
When a pack of wolves chased them, they galloped away.
They found rich grass on the highlands.
Colts grew to be larger than their mothers.
