Dresses (To Preserve Colours Of). The colours of merinos, mousseline-de-laines, ginghams, chintzes, printed lawns, etc., may be preserved by using water that is only milk-warm ; making a lather with white soap, before you put in the dress, instead of rubbing it on the material; and stirring into a first and second tub of water a large tablespoonful of ox-gall. The gall can be obtained from the butcher, and a bottle of it should always be kept in every house. No coloured articles should be allowed to remain long in the water. They must be washed fast, and then rinsed through two cold waters. Into each rinsing water, stir a teaspoonful of vinegar, which will help to brighten the colours; and after rinsing, hang them out immediately. When ironing-dry (or still a little damp), bring them in ; have irons ready heated, and iron them at once, as it injures the colours to allow them to remain damp too long, or to sprinkle and roll them up in a covering for ironing next day. If they cannot be conveniently ironed Immediately, let them hang till they are quite dry ; and then damp and fold them on the following day. a quarter of an hour before ironing. The best way is not to do coloured dresses on the day of the general wash, but to give them a morning by themselves. They should only be undertaken in clear bright weather. If allowed to freeze, the colours will be irreparably injured. We need scarcely say that no coloured articles should ever be boiled or scalded. If you get from a shop a slip for testing the durability of colours, give it a fair trial by washing it as above; afterwards, pinning it to the edge of a towel, and hanging it to dry. Some colours, (especially pinks and light greens,) though they may stand perfectly well in washing, will change as soon as a warm iron is applied to them; the pink turning purplish, and the green bluish. No coloured articles should be smoothed with a hot iron.
