"They saw the flicker of bats overhead." ...

"They lay on their heathery beds and listened to all the sounds of the night. They heard the little grunt of a hedgehog going by. They saw the flicker of bats overhead. They smelt the drifting scent of honeysuckle, and the delicious smell of wild thyme crushed under their bodies. A reed-warbler sang a beautiful little song in the reeds below, and then another answered."

From The Secret Island by Enid Blyton.

Enid Blyton should be mandatory reading for all children before they become jaded with the world.
