                     How They found the Magic Wood

There were once three children, called NAME_1, NAME_2, and NAME_3. All their
lives they had lived in a town, but now their father had a job in the
country, so they were all to move as soon as ever they could.

“What fun to be in the country!” said NAME_1. “I shall learn all about
animals and birds!”

“And I shall pick as many flowers as I want to,” said NAME_2.
