Rooms which are in constant use should be swept and dusted every day. A thorough cleaning of each room in the house will be necessary every week or two, even though the room is swept and kept in order daily. First, all cupboards, drawers, and other receptacles in which articles collect should be cleaned; then all large movable articles should be dusted and moved out of the room; those that are not readily movable should be dusted and covered. The floor should be swept with the windows open; the ceiling and walls should be brushed with a covered broom, and the dust allowed to settle. The floor should then be wiped with a damp cloth on the broom.[A] The woodwork should be cleaned with a damp cloth and a soap that is not too strong. Soda or sapolio should not be used. The furniture should be carefully uncovered, and everything arranged in perfect order. [A] If the floor is of unfinished-wood, it will require a thorough scrubbing. After sweeping the floor and allowing the dust to settle, a small portion at a time should be scrubbed with a floor-brush and soap. When scrubbing, the grain of the wood should be followed. The scrubbing-water should be changed frequently. For rinsing and drying the floor, a cloth should be wrung out of clear water. The things that are highest should be dusted first, and care should be taken to collect all the dust in the dust-cloth. After collecting the dust, the cloth should be shaken out-of-doors, washed thoroughly, and boiled. The dust-cloth should be dampened before using on all surfaces except the polished furniture and windows. Sweeping should be done with short strokes and the broom should be kept close to the floor, so that the dust will not be scattered. The corners of the room should be swept first, the dust gathered in the centre, and then swept into the dust-pan. The dust should be burned, for it may contain disease germs. Loose hairs and fluff should be removed from the broom after using, and it should also be washed periodically. Small rugs should be cleaned out-of-doors. They should be swept, beaten, and re-swept, then rolled until ready to be put on the floor. If the rug is a large one and cannot be removed, it should be wiped over with a damp cloth, rolled, and the under side of the rug and the floor beneath it should be wiped. After the room has been cleaned, the windows should be arranged so that a supply of fresh, clean air can come constantly into it. This is essential to every room in the house, if perfect health is to be maintained. PRELIMINARY PLAN It will be well to have Lesson IX given in one of the homes some day after school hours, if possible. If that cannot be arranged, the school-room may be utilized as the place for practice. METHOD OF WORK
