four o'clock
`` Z for Zebra , '' said Nannie . When the new nursery was all ready , Nannie was sent for . A dozen times that day I ran up that narrow staircase , and in the morning I laid the tea to see how it would look , and it looked so pretty that I left it . At four o'clock the fire was lighted and the kettle was put on to boil . Nannie drove up in a four wheeler . I was in the hall to meet her . She lingered to look at everything .
