The chauffeur got down and did something inexplicable to the machinery with a spanner. And the spanner broke.

"I'll just run across and get a new one, sir," said the chauffeur.

"It's getting late," said Bob. "Don't be long, and before you go start her up."

The driver set her going, and the bishop caught hold of Bob.

"You're not off? This is very surprising. It makes a very curious noise."

"There won't be any to speak of when we get her moving," said Bob. "You see the engine is going, and when we like we can start at once."

He was happy, bright, and eager.

"There's a motor-car coming," whispered the bishop.

Bob jumped.

"I say, it's yellow like Pen's big new one," he said. And the car stopped in front of the post-office ten yards away. Bob grabbed the bishop's arm.
