"You heard what I called you?" I said to him. "A thing. So don't go putting yourself forward." He gazed up innocently from under my arm. "What shall we get first?" he asked. "I want the engine-room. The locomotive in the home. The boy's own railroad track." "That's downstairs. But did you really think of an engine? I mean, isn't it rather large and heavy? Why not get a--" I smacked his head, and we went downstairs. It was a delightful room. I was introduced to practically the whole of the Great Western Railway's rolling stock. "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." I got about thirty feet, and then turned to switches and signals and lamps and things. I bought a lot of those. You never know what emergency might not arise on the nursery floor, and if anything happened for want of a switch or two I should never forgive myself. Just as we were going away I caught sight of the jolliest little clockwork torpedo boat. I stopped irresolute. "Don't be silly," said the voice under my arm. "You'll never be asked to the house again if you give that." "Why not?" "Wait till the children have fallen into the bath once or twice with all their clothes on, and then ask the mother why not." "I see," I said stiffly, and we went upstairs. "The next thing we want is bricks." "Bricks," said Father Christmas uneasily. "Bricks. Yes, there's bricks. Have you ever thought of one of those nice little woolly rabbits--" "Where do we get bricks?" "Bricks. You know, I don't think mothers are as fond as all that of BRICKS." "I got the mother's present yesterday, thanks very much. This is for one of the children." They showed me bricks and they showed me pictures of what the bricks would build. Palaces, simply palaces. Gone was the Balbus-wall of our youth; gone was the fort with its arrow-holes for the archers. Nothing now but temples and Moorish palaces. "Jove, I should love that," I said." I mean HE would love that. Do you want much land for a house of that size? I know of a site on the nursery floor, but--well, of course, we could always have an iron building outside in the passage for the billiard table." We paid and moved off again. "What are you mumbling about now?" I asked. "I said you'll only make the boy discontented with his present home if you teach him to build nothing but castles and ruined abbeys and things. And you WILL run to bulk. Half of those bricks would have made a very nice present for anybody."
