Moths.—These are apt to develop in woollen clothes unless the garments are thoroughly shaken and absolutely protected by wrapping in newspapers before being put away. Woollen garments that are used only occasionally should be kept in a light, dry place, examined frequently, and hung in the sun occasionally. Moths or carpet beetles can be exterminated by the use of kerosene.
PRELIMINARY PLAN
Give this lesson at a time when the pupils are asking about household pests or when the school is suffering from them. It would be well to have it in the spring, just before the school closes, so that the pupils may immediately put into practice what they learn. It may be desirable to devote their efforts to the destruction of one particular pest; for example, a fly crusade may be inaugurated.
METHOD OF WORK
If there are pests in the school-room, discuss their habits, what seems to attract them, where they come from, etc. Have the pupils report any that they may have at home. Explain why they are dangerous, tell how they can be exterminated, and assign to each pupil the task of exterminating one household pest. Have her report, each day, the success of her efforts. Continue this work for several weeks.
LESSON XIII: REMOVING STAINS, BLEACHING FABRICS, AND SETTING COLOURS
SUBJECT MATTER
As garments and household linens are apt to become stained and thus lose their attractiveness, it is well to know the remedies for the most common stains and the principle upon which their removal depends. All stains should be removed as soon as possible. Boiling water will loosen and remove coffee, tea, and fresh fruit stains. The stained spot should be held over a bowl, and the water should be poured upon it with some force. Cold water will remove stains made by blood or meat juice. Soaking will help in the removal of blood stains. Rust stains may be removed by wetting the stained spot with lemon juice, covering it with salt, and placing the stained fabric in the sun. Stains from stove blacking, paint, and grass may be removed by soaking in kerosene and washing well with soap and water. Ink stains may be removed by soaking in water, removing as much of the stain as possible, and then soaking in milk. Stains from cream and other forms of grease may be washed out in cold water, followed by warm water and soap.
White cotton and white linen materials may be bleached by exposure to the sunshine while still damp. If they are left out overnight, the bleaching process is made effective by the moisture furnished by dew or frost. A stream of steam from the tea-kettle may also help in the bleaching process.
