They lay down on the soft heather, and pulled the old rug over them. The springy heather was softer than the old hard bed the two girls had been used to at home. The little girls put their arms round one another and shut their eyes. They were fast asleep almost at once.

But the boys did not sleep so quickly. 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.

“Is that a blackbird?” asked Mike.

“No, a reed-warbler,” said Jack. “They sing as beautifully as any bird that sings in the daytime! Listen, do you hear that owl?”

“Oooo-ooo-ooo-oooo!” came a long, quivering sound; “ooo-ooo-ooo-ooo!”

“He’s hunting for rats and voles,” said Jack. “I say, look at the stars, Mike?”

“Don’t they seem far away?” said Mike, looking up into the purple night sky, which was set with thousands of bright stars. “I say, Jack, it’s awfully nice of you to come away with us like this and share your secret island.”

“It isn’t nice of me at all,” said Jack. “I wanted to. I’m doing just exactly what I most want to do. I only hope we shan’t be found and taken back, but I’ll take jolly good care no one finds us! I’m laying my plans already!”

But Mike was not listening. His eyes shut, he forgot the owls and the stars; he fell asleep and dreamt of building a house with Jack, a lovely house.

Jack fell asleep, too. And soon the rabbits that lived under their gorse-bush came slyly out and peeped at the sleeping children in surprise. Who were they?
