That second-floor arch in a London house, looking up and down the well of the staircase and commanding the main thoroughfare by which the inhabitants are passing; by which cook lurks down before daylight to scour her pots and pans in the kitchen; by which young master stealthily ascends, having left his boots in the hall, and let himself in after dawn from a jolly night at the Club; down which miss comes rustling in fresh ribbons and spreading muslins, brilliant and beautiful, and prepared for conquest and the ball; or Master Tommy slides, preferring the banisters for a mode of conveyance, and disdaining danger and the stair; down which the mother is fondly carried smiling in her strong husband's arms, as he steps steadily step by step, and followed by the monthly nurse, on the day when the medical man has pronounced that the charming patient may go downstairs; up which John lurks to bed, yawning, with a sputtering tallow candle, and to gather up before sunrise the boots which are awaiting him in the passages--that stair, up or down which babies are carried, old people are helped, guests are marshalled to the ball, the parson walks to the christening, the doctor to the sick-room, and the undertaker's men to the upper floor--what a memento of Life, Death, and Vanity it is--that arch and stair--if you choose to consider it, and sit on the landing, looking up and down the well!
