As soon as you quit your bed, take off the bedclothes, (each article separately,) and spread them widely over the chairs, turning the mattrass or bed as far down as it will go. This will give the bedding time to air; and in all houses it should be done every morning, the whole year round. Before you leave the room, raise the windows as high as they will go, (unless it should be raining, or snowing,) that the apartment may be well ventilated. Fortunate are those who have been accustomed to sleeping always with the sash more or less open, according to the weather, or the season. Their health will be much the better for the excellent practice of constantly admitting fresh air into their sleeping-room. See Dr. Franklin's essay on the "Art of Sleeping Well." Mr. Combe, who has written copiously on this subject, says it not only improves the health, but the complexion; and that ladies who follow this practice continue to look young long after those who sleep in close rooms have faded and shrivelled. Except in a very unhealthy climate, or in the neighbourhood of marshes, no external air can be so unwholesome, or productive of such baneful effects on the constitution, as the same air breathed over and over again in a close room, and returning continually to the lungs, till before morning it becomes unfit to be breathed at all. Sleeping with the windows closed in a room newly painted has produced fatal diseases. To some lungs the vapour of white lead is poisonous. To none is it quite innoxious. Its dangerous properties may be neutralized by placing in newly-painted rooms, large tubs of water, into each of which has been mixed an ounce of vitriol. The tubs must be set near the walls, and the water and vitriol renewed every day. The introduction of zinc-paint promises to put that of white lead out of use; as zinc is quite as cheap, and not at all pernicious to health.

At sleeping hours the air of a bedroom should be perfectly free from all scents, either pleasant or otherwise. Many persons cannot sleep with flowers in their chamber, or with any sort of perfume. It is best not.

If when on a visit, you find that the chambermaid does not make your bed so that you can sleep comfortably, show her how to do it, (privately,) but say nothing to your hostess. There is but one way of making a bed properly; and yet it is surprising how little that way is known or remembered. First, shake up the bed high and evenly; turning it over, and see that the foot is not higher than the head. If there is a mattrass above the bed, turn the mattrass half up, and then half down, till you have shaken up the bed beneath. Next spread on the under-sheet, laying it well over the bolster to secure it from dragging down and getting under the shoulders. However, to most beds now, there is a bolster-case. Then tuck in the under-sheet, well, at both sides, to prevent its getting loose and disordered in the night. For the same reason tuck in the upper-sheet, well, at the foot, leaving the sides loose. Tuck in the blankets at bottom, but not at the sides. Lay the counterpane smoothly over the whole. Turn it down at the top; and turn down the upper-sheet above it, so as to conceal the blankets entirely.

Should the chambermaid neglect your room, or be remiss in filling your pitchers, or in furnishing you with clean towels, speak to her on the subject when alone. She will hardly, for her own sake, inform her mistress that you have had occasion to find fault with her; unless she is very insolent or sulky, she will say she is sorry, and will promise to do better in future. Complaining to her mistress of these neglects will probably give offence to the lady, who may be of that wayward (though too common) disposition which will allow no one except herself, to find any deficiency in her servants. As mistresses are frequently very touchy on these points, your hostess may hint that your statement is incredible, and that "no one ever complained before." Above all things, avoid letting her know that you have found or felt insects in your bed; a circumstance that may chance sometimes to happen even in the best kept houses. In a warm climate, or in an old house, the utmost care and the most vigilant neatness cannot always prevent it. It may be caused by the bringing of baggage from boats, or ships, and by servants neglecting their own beds; a too common practice with them, unless the mistress or her housekeeper compels them to be cleanly, and sees that they are so.

If you have proof positive that your bed is not free from these intolerable nuisances, confide this fact to the chambermaid only, and desire her to attend to it speedily. She will do so the more readily, if you promise her a reward in case of complete success. Enjoining her to manage this as quietly as possible, and to say nothing about it to any one, may spare you a scene with your hostess; who, though you have always regarded her as your warm friend, may, notwithstanding, become your enemy for life, in consequence of your having presumed to be incommoded in her house, where "nobody ever complained before." A well-bred, sensible, good-tempered woman will not, of course, take offence for such a cause; and will believe that there must have been good reason for the complaint, rather than suppose that her guest and her friend would mention so delicate a subject even to a servant, unless there was positive proof. And she will rightly think it was well to make it known, and have it immediately remedied. But all women who invite friends to visit them, are not sensible and good-tempered. Therefore, take care.

For similar reasons, should a servant purloin any article belonging to you, (and servants, considered quite honest, will sometimes pilfer from a visiter when they would not dare to do so from their mistress,) it is safest to pass it over, unless the article stolen is of consequence. You may find your hostess very unwilling to believe that a servant of hers could possibly be dishonest; and much may be said, or evidently thought, that will be very painful to you, her guest.

Notwithstanding all that may be said to you about "feeling yourself perfectly at home," and "considering your friend's house as your own," be very careful not literally to do so. In fact, it is impossible you should with any propriety—particularly, if it is your first visit. You cannot possibly know the real character and disposition of any acquaintance, till after you have had some experience in living under the same roof. If you find your hostess all that you can desire, and that she is making your visit every way agreeable, be very grateful to her, and let her understand that you are exceedingly happy at her house; but avoid staying too long, or taxing her kindness too highly.

Avoid encroaching unreasonably upon her time. Expect her not to devote an undue portion of it to you. She will probably be engaged in the superintendence of household affairs, or in the care of her young children, for two or three hours after breakfast. So at these hours do not intrude upon her,—but amuse yourself with some occupation of your own, till you see that it is convenient to the family for you to join them in the sitting-room. In summer afternoons, retire for an hour or more, soon after dinner, to your own apartment, that you may give your friends an opportunity of taking their naps, and that you may do the same yourself. You will be brighter in the evening, from indulging in this practice; and less likely to feel sleepy, when you ought to be wide awake, and ready to assist in entertaining your entertainers. A silent visiter, whether silent from dulness or indolence, or a habit of taciturnity, is never an agreeable one.

Yet, however pleasant the conversation, have sufficient self-denial to break off in seasonable time, so as not to keep the family up by continuing in the parlour till a late hour. Some of them may be tired and sleepy, though you are not. And between ten and eleven o'clock it is well to retire.

If you have shopping to do, and are acquainted with the town, you can be under no necessity of imposing on any lady of the family the task of accompanying you. To shop for others, or with others, is a most irksome fatigue. Even when a stranger in the place, you can easily, by enquiring of the family, learn where the best stores are to be found, and go to them by yourself.
