I smacked his head, and we went downstairs.

"Engine, three carriages and a guard's van. That's right. Then I shall want some rails, of course…. SHUT up, will you?" I said angrily, when the attendant was out of hearing.

"It's the extra weight," he sighed. "The reindeer don't like it. And these modern chimneys—you've no idea what a squeeze it is. However—"

"Those are very jolly," I said when I had examined the rails. "I shall want about a mile of them. Threepence ha'penny a foot? Then I shan't want nearly a mile."

Just as we were going away I caught sight of the jolliest little clockwork torpedo boat. I stopped irresolute.
