Children, boys and girls alike, should be instructed never to leave their bedrooms without at least throwing back the bedclothes and raising the windows; and guests in a family, one would suppose, will do this for their own comfort; but it is well that every housekeeper should be sure that it is done before she goes to the kitchen or breakfast-room. It is particularly desirable that our children become accustomed to this kind of care and attention to their sleeping-rooms; for if the habit is fixed in early youth, when absent from a mother’s care, in school, college, or business, and compelled to board, whatever other discomforts they may be subjected to, they can secure for themselves well-ventilated beds and sleeping-rooms. If, from extra morning duties or ill health, you are not able to attend to this part of the chamber-work yourself, then, as soon as the rooms are all vacated, the chambermaid should go to them at once, taking with her the chamber pail and cloths, and, first opening the windows and putting bedclothes and mattresses to air, as above mentioned, should empty all slops, wash out the washstands and all pertaining to them,--pitchers, soap-cup, tooth- and nail-brush holders,--gather up all dirty clothes and towels, and put them into the basket, or, if wet, hang up to dry. By the time this is faithfully done, the chambermaid will be ready to go to her own breakfast, leaving the windows open, unless in stormy weather, and the beds unmade. Keep strict watch that the servants do not fail to air their own rooms and spread open their beds when they come down to their early morning’s work. Never fear to open chamber windows in stormy weather. If the rain or snow beats in badly, drop the window from the top a little way, or spread an old bit of bagging or oil-cloth before the window to protect the carpet; but in spite of wind or weather, have a full current of fresh air pass through your bedchambers every morning. Once a week mattresses must be thoroughly brushed with a whisk-broom, and the tufts or buttons that tack them together cleaned with a round pointed brush, called a button-brush, so that no lint or dust can lodge about them to shelter moths. When free from lint and dirt, throw the mattress across a table, or spread on the floor an old sheet kept for that purpose, and lay it on that. In the same manner brush the under-bed; then turn it up and with a wet cloth wipe off the inside of the bedstead, raising up the slats that no lint may remain lodged there. By such care you will save much trouble from moths and bugs. It is well to attend to this on Friday, or whichever day may be set apart for sweeping, as lint may be dropped on the carpet, and should be at once removed. V. HOUSE-CLEANING.
