"If it had not been for Rover, the house might have burned down," said Farmer Hill.

"Rover is a good dog," said Mrs. Hill as she patted him.

"Good dog, good dog!" said John and Sue.

They gave Rover a nice warm blanket to lie on, and fixed the stove so it could not draw so hard.

Then the family went back to sleep.

Rover lay down on the blanket, but he did not go to sleep.

All that night he kept watch.
