The oak-panelled room was, it can hardly be denied, difficult to light at night, as the dark walls absorbed the candle rays. But that mattered little at a time when every one went to bed with the sun. When later hours were kept, then the oak panels were painted white. But now that we have mineral oils, not to mention gas and electric lighting, we may well scrape off the white paint and restore the dark oak. Then, for an evening, the sombre background has quite a marvellous effect in setting off the bright ladies' dresses, and showing off fresh pretty faces. [Illustration: An Oak-panelled Parlour, Lew Trenchard.] Before the reign of Elizabeth the staircase was not an important feature in the house. The hall reached to the roof, and the stairs were winding flights of stone steps in turrets, or in the thickness of the wall; when the fashion set in to ceil the halls low, then the staircase became a stately feature of the house. But it was more than a stately feature, it was the great ventilating shaft of the house; it was to the house what the tower is to the church, the chimney by which the stale fumes might pass away. The great staircase window, made up of thousands of little pieces of glass set in lead, acted as a colander through which the outer air streamed in and the inner vitiated air escaped. Where there is a central quadrangle, this was in many cases glazed in; then a staircase led to a series of galleries about it, lighted from above, communicating with the several suites of apartments. Many of our old inns are thus constructed. The reader will remember the picture of the court of the White Hart in _Pickwick_, with the first introduction of Sam Weller. The central court serves as a ventilator to the house, and so does its dwindled representative, the well-staircase. Those fools, our forefathers, again, if they shut out the winds and gave shelter to their houses, made ample provision for internal ventilation.
