Every mistress of a family should see not only that all sleeping-rooms in her house can be well ventilated at night, but that they actually are so. Where there is no open fireplace to admit the pure air from the exterior, a door should be left open into an entry, or room where fresh air is admitted; or else a small opening should be made in the top and bottom of a window, taking care not to allow a draught of air to cross the bed. The debility of childhood, the lassitude of domestics, and the ill health of families, are often caused by neglecting to provide a supply of pure air. Straw matting is best for a chamber carpet, and strips of woolen carpeting may be laid by the side of the bed. Where chambers have no closets, a wardrobe is indispensable. A low square box, set on casters, with a cushion on the top, and a drawer on one side to put shoes in, is a great convenience in dressing the feet. An old Champagne basket, fitted up with a cushion on the lid, and a valance fastened to it to cover the sides, can be used for the same purpose.

Another convenience, for a room where sewing is done in summer, is a fancy jar, set in one corner, to receive clippings, and any other rubbish. It can be covered with prints or paintings, and varnished, and then looks very prettily.

The trunks in a chamber can be improved in looks and comfort by making cushions of the same size and shape, stuffed with hay and covered with chintz, with a frill reaching nearly to the floor.

Every bed-chamber should have a wash-stand, bowl, pitcher, and tumbler, with a wash-bucket under the stand, to receive slops. A light screen, made like a clothes-frame, and covered with paper or chintz, should be furnished for bedrooms occupied by two persons, so that ablutions can be performed in privacy. It can be ornamented, so as to look well anywhere. A little frame, or towel-horse, by the wash-stand, on which to dry towels, is a convenience. A wash-stand should be furnished with a sponge or wash-cloth, and a small towel, for wiping the basin after using it. This should be hung on the wash-stand or towel-horse, for constant use. A soap-dish, and a dish for tooth-brushes, are neat and convenient, and each person should be furnished with two towels; one for the feet, and one for other purposes.

It is in good taste to have the curtains, bed-quilt, valance, and window-curtains of similar materials. In making feather-beds, side-pieces should be put in, like those of mattresses, and the bed should be well filled, so that a person will not be buried in a hollow, which is not healthful, save in extremely cold weather. Feather-beds should never be used except in cold weather. At other times, a thin mattress of hair, cotton and moss, or straw, should be put over them. A simple strip of broad straw matting, spread over a featherbed, answers the same purpose. Nothing is more debilitating than, in warm weather, to sleep with a feather-bed pressing round the greater part of the body. Pillows stuffed with papers an inch square are good for summer, especially for young children, whose heads should be kept cool. The cheapest and best covering of a bed, for winter, is a cotton comforter, made to contain three or four pounds of cotton, laid in bats or sheets, between covers tacked together at regular intervals. They should be three yards square, and less cotton should be put at the sides that are tucked in. It is better to have two thin comforters to each bed, than one thick one; as then the covering can be regulated according to the weather.

Few domestics will make a bed properly without much attention from the mistress of the family. The following di-rections should be given to those who do this work:

Open the windows, and lay off the bed-covering, on two chairs, at the foot of the bed. After the bed is well aired, shake the feathers, from each corner to the middle; then take up the middle, and shake it well, and turn the bed over. Then push the feathers in place, making the head higher than the foot, and the sides even, and as high as the middle part. Then put on the bolster and the under sheet, so that the wrong side of the sheet shall go next the bed, and the marking come at the head, tucking in all around. Then put on the pillows, even, so that the open ends shall come to the sides of the bed, and then spread on the upper sheet, so that the wrong side shall be next the blankets and the marked end at the head. This arrangement of sheets is to prevent the part where the feet lie from being reversed, so as to come to the face, and also to prevent the parts soiled by the body from coming to the bed-tick and blankets. Then put on the other covering, except the outer one, tucking in all around, and then turn over the upper sheet, at the head, so as to show a part of the pillows. When the pillow-cases are clean and smooth, they look best outside of the cover, but not otherwise. Then draw the hand along the side of the pillows, to make an even indentation, and then smooth and shape the whole outside. A nice housekeeper always notices the manner in which a bed is made; and in some parts of the country it is rare to see this work properly performed.

The writer would here urge every mistress of a family who keeps more than one domestic to provide them with single beds, that they may not be obliged to sleep with all the changing domestics, who come and go so often. Where the room is too small for two beds, a narrow truckle-bed under another will answer. Domestics should be furnished with washing conveniences in their chambers, and be encouraged to keep their persons and rooms neat and in order.
