_The Walls._--Walls are panelled, or painted, or calcimined, or covered with fabric or paper. Wood, paint and calcimine are considered cleaner than other coverings, but all can be kept up to an ordinary standard of cleanliness. Panelling should be carefully wiped with the wool-headed mop used for the ceiling, or with a cloth where it is within reach. If the wood is dark and polished, it may now and again be rubbed with a little good furniture polish; if it is light or unpolished it is better to content oneself with wiping off the dust. Fabric-covered walls should be cleaned once or twice a year with a vacuum cleaner. If this is not possible, they may be as often brushed. This must not be done violently, but carefully, and preferably with a hair broom--a white hair broom such as one uses for clothes, if the wall covering is especially handsome or delicate in colour. Painted walls may be wiped with a dry or dampened mop, or they may be washed with soap and water, or even with disinfectant, should this happen to be desirable. Calcimined walls may be wiped only with a soft mop, or very gently with a broom in a bag. Mop or broom bag must often be shaken out of the window, otherwise the walls will be smirched or clouded. Very little in the way of restoration or cleaning should be attempted with calcimine, for it almost invariably makes a bad matter worse. Spots such as are made by hands or heads can sometimes be removed by rubbing them with a piece of dry bread, or with some corn meal. It is safe to experiment with any _dry_ remedy; but a wet remedy will always fail. Even calcimine itself, put over a spot or a scar, will leave a mark. Papered walls may be wiped with a dry mop, or a broom in a bag. They are not as easily smirched as calcimine, but one must frequently shake out of doors, or else change any brush or cloth used for wiping walls. If you need a reason for wiping walls and ceilings, look at the mop or the cover of the broom with which you have done the work. Dirt is the enemy of health and loveliness. _Woodwork._--When woodwork is cleaned, all cracks, ornaments and irregularities should first be gone over with a small, soft brush. A flat brush such as is used for varnishing is good. If the woodwork is not polished, it should next be carefully--that is, every inch of it--wiped and rubbed with a soft, dry cloth, or if the room is exceedingly dusty, with a cloth very slightly dampened. Any sort of oil, or polish, or even water is apt to darken or spot unpolished wood. In the case of baseboards and window ledges, however, a little dressing of some kind should occasionally be rubbed into them, for they have to be defended from dampness in the one case, and hard usage in the second. A little of the polish used for floors will do very well for this purpose.
