some instatices it is greatly to be preferred. Washing-soda and lye, unless thoroughly linsed from clothing, have a tend- ency to cause yellowing, particularly when starch is used after- ward- BorBJLj on the other hand, has a tendency to whiten fabrics and is added directly to starch, in order to give it good color and to increase its clearness. When colored fabrics or wools are to be washed in hard water, borax is one of the best alkalis to use for softening the water. Ammonia {ammmdum hydroxide) is another good alkali for softening water when it is not advisable to use stronger alkalis. Ammonia is a very volatile substance, consequently it should be used only when the laundiy process is to be conducted quickly. It is better and cheaper to purchase the full-strengUi ammonia from a druggist and then dilute it, than to buy the article known as household ammonia, which is of unknown strength* How to soften tiJoter. Both permanently and temporarily hard water may l>e softened by distillation, but that method involves apparatus not practicable for the average home. If water is temporarOy hard, however^ it may be softened by being boiled, then ^owed to stand until the lime settlai. The top water is afterward drawn off* Boiling water to softrn it is without doubt the best method if it softens the water ^w^- ficiently, since no harmful chemicals are left in the water to injure fabrics. Either temporarily or permanently hard water may he* softened by adding lime or washing-soda to the water, tli(*ii blowing it to stand in open kegs for several days before its u^t^ The water should then be drawn from the top. If the water is boiled after the addition of the softening agent, the time fi>^ standing may be considerably 1^3ened, Neither of the tu'i* processes just described is much in use in the household, ij^i^*''^' the time consumed by them is often considered unwarranted The more common method is to add washing-soda^ lye, bonix, or ammonia at the time of washing.

In softening water, the objec- rttin to the use of any chemical is the injury it may do to the fabric. Washing-soda (sodium carbonate) is the best alkali to soften water for geneml household use, for, while effective in its action, it is not so corrosive as to render its handling difficult or its u<e unduly harmful, nor is it expensive. It should never be used in its dry form, however, for it is an alkaH sufficiently strong to eat holes in a fabric if it is used in full strength, and wherever a particle of the dry substance falls, a strong solution Ls formed* Carelessness causes many of the complaints against present-day laundry methods.
