Where only one or two servants are kept, the mistress will do well not to leave her chamber before she has opened her windows and laid the bed-clothes back over two chairs, so as to ensure the sheets and blankets, heated by the contact with the body all night, being well aired and cooled. No bed should be made, or night-dress folded up, until it has been aired, and suffered thoroughly to cool for at least two hours. Nurseries should be aired while the children are at breakfast, and while they are taking their morning walk. Dining and drawing-rooms require a current of fresh air passed through them at least once every day, to dislodge all the vitiated air tainted by the smell of food, flowers, &c., and by having been inhaled by those using the rooms. Many of our readers have doubtless been struck, on entering some houses, by the close, faint, unwholesome smell they, coming from the fresh air, at once perceive. Those who dwell in it habitually are not conscious of it. They dread the chill of fresh air, or the dust or smuts it will bring with it into their rooms; and therefore shut it carefully out, and cherish in its stead a species of slow poison—a heavy atmosphere loaded with all sorts of pernicious gases. Light, too, is another forbidden luxury in some houses. Heavy Venetian blinds jealously protect the delicate hues of the curtains and carpets from its influence, and the inmates consequently fade, instead of the upholstery; for a human being can no more do without light than can a flower, and we only need place this latter in a cellar for a few days, and we shall see how it will look. It must not, however, be supposed that we would recklessly suffer the noonday sun to shine on our damask curtains or tapestry carpets, or that we should open our windows when rain, hail, or snow beat full upon them; all we wish to do is to advise such a use of God’s choicest gifts as health requires, and common sense dictates. Nor is it only with a view to exercising a salutary influence upon her domestics, and strengthening herself, that we would counsel our housewife to pay strict attention to all matters of sanitary importance. A female writer of some celebrity has said—“If before marriage a woman has been deluded into the notion that a multiplicity of small ailments invested her character with an interesting kind of delicacy, the sooner she becomes well after marriage the better for herself and all around her.”
