She was moved out of Mamma's room to sleep by herself on the top floor in the night nursery. And the day nursery was turned into the boys' schoolroom. When you were little and slept in the cot behind the curtain Mamma would sometimes come and read you to sleep with the bits you wanted: "The Lord is my Shepherd," and "Or ever the silver cord be loosed or the golden bowl be broken, or the pitcher be broken at the fountain or the wheel broken at the cistern," and "the city had no need of the sun, neither of the moon, to shine in it; for the glory of God did lighten it, and the Lamb is the light thereof." When you were frightened she taught you to say, "He that dwelleth in the secret place of the Most High shall abide under the shadow of the Almighty.... He shall cover thee with His feathers and under His wings shalt thou trust.... Thou shalt not be afraid for the terror by night." And you were allowed to have a night-light. Now it was all different. You went to bed half an hour later, while Mamma was dressing for dinner, and when she came to tuck you up the bell rang and she had to run downstairs, quick, so as not to keep Papa waiting. You hung on to her neck and untucked yourself, and she always got away before you could kiss her seven times. And there was no night-light. You had to read the Bible in the morning, and it always had to be the bits Mamma wanted, out of Genesis and the Gospel of St. John. You had to learn about the one God and the three Persons. The one God was the nice, clever, happy God who made Mamma and Mark and Jenny and the sun and Sarah and the kittens. He was the God you really believed in. At night when you lay on your back in the dark you thought about being born and about arithmetic and God. The sacred number three went into eighteen sixty-nine and didn't come out again; so did seven. She liked numbers that fitted like that with no loose ends left over. Mr. Sippett said there were things you could do with the loose ends of numbers to make them fit. That was fractions. Supposing there was somewhere in the world a number that simply wouldn't fit? Mr. Sippett said there was no such number. But queer things happened. You were seven years old, yet you had had eight birthdays. There was the day you were born, January the twenty-fourth, eighteen sixty-three, at five o'clock in the morning. When you were born you weren't any age at all, not a minute old, not a second, not half a second. But there was eighteen sixty-two and there was January the twenty-third and the minute just before you were born. You couldn't really tell when the twenty-third ended and the twenty-fourth began; because when you counted sixty minutes for the hour and sixty seconds for the minute, there was still the half second and the half of that, and so on for ever and ever.
