"Shows?" he repeated, questioningly.

"Roundabouts," she explained.

"Oh!" he said. "That's nothing. Come in here!"

She put down the basket and followed him with a look of pleasure. She glanced furtively at the roof as they passed through the doorway, and stepped quickly close up to him, her eyes rolled widely round in obvious apprehension. He looked at her with amusement.

She caught his eye and smiled too. "Lovely," she said, as she glanced round the clean and well-kept little engine-room. "Lovely," she repeated, as her eyes were held by the bright lacquered copper switches and instruments set on the enamelled slate switchboard.

"It's like a church."

He looked at her quickly. "Have you ever been to church?"

"I've been inside and I've looked in through the windows," she answered.

"What do you do on Sundays?" he asked.

"Nothing."
