of that manufacturer who allows the use of a rusting screw here or a bolt there when the rest of the equipment is safeguarded against such conditions. In one specific instance a single part of a machine intended to be used in connection with water was made up of five different metals. Each one of these metals had its own different reaction towards hard water in the presence of soap. That this manufacturer had intended no slight toward his product was indicated by the fact that the largest section of this part was constructed of the most expensive material. He probably fully believed that he had made that particular part of rustproof material but it was the selection of defective small parts that offset any advantage due to his use of fine materials for the major part of the machine.

THE RELATION OF SECTIONAL SELLING TO MATERIALS USED.
Because a great deal of household equipment that is of interest to women must be used as a water container, the effect of water of varying degrees of hardness upon the several metals is of interest. Most metals have some electrolytic action. There are throughout the country water supplies of every known degree of hardness. There are water supplies whose hardness can be corrected and there are supplies of the type known as "permanent" hardness. In actual practice the salts in these hard waters react with soap of any variety to form a sticky gray precipitate. This precipitate is increased in quantity in direct proportion to the activity of the metal. Therefore, the material selected for the tub and cylinder of a washing machine, for the container of the dishwashing machine, or for the tea kettle that demands constant contact with water should be given the careful attention that its importance demands.
In selecting a Refrigerator, the woman looks for:
1. Seamless lining.
2. Compartment beneath ice high enough to hold quart milk bottles.
3. Generous insulation.
4. A selection of wood and treatment of it that will prevent warping.
5. Heavy hardware.
6. Positive-closing, lever locks.
7. Plain unpanelled trim--high leg base.
8. Dull, rather than highly finished wood.
9. Easily accessible drain.
10. Adjustable shelves.
A universal metal that can withstand any and all attacks of these several waters is difficult if not impossible to locate. In our judgment there is no perfect metal. Copper comes the nearest to it and yet copper must be tinned, and there is some slight consumer reaction against its use, in large containers, because they claim copper must be scoured in order to be sightly. However, enamel paint on the outside of such a container, leaving only a fair sized name-plate to be burnished, would overcome this objection.
Galvanized iron, zinc, nickel, all have a disadvantage of inducing electrolytic action (producing whitish precipitate) and that should be taken into account in your selection of metals. In sections save those in which waters are of the "permanent hard" variety, this disadvantage can be overcome by including directions that the machine should not be scoured. Flush with rinsing water only. With such care, the whitish deposit acts as a film over the metal, and, once the latter is completely covered, reduces the precipitation. But in the presence of extremely hard waters, the quantity is so great that the precipitate snows a tendency to deposit on the linen itself, instead of being thrown solely to the sides of tub, cylinder, or suction cup. Once this does get on the fabric, it has all the sticky characteristics of chewing gum.
Bronze or brass rather than steel or iron should be used for any bearings that come in contact with water. Only thus can you fully safeguard against rust.

LITTLE THINGS THAT OFTEN PROVE GREAT.
Safety demands that every equipment involving an electric motor be so fully insulated from the machine frame by water-proof fittings and insulated shaft couplings, etc., that a maximum of safety can be assured. It is indeed remarkable that this is not more often cared for in the original design. In one short period, at least three machines were forced into the disapproval group in the Department of Household Engineering of Good Housekeeping Institute with such lack of insulation as one of the causes.
It is thus clear that consumer needs, in this great classification of merchandise (household appliances) as reflected by consumer attitude are often ill-defined and extremely difficult for the manufacturer to interpret. Therefore, as a recognition of this condition, the basic purpose running throughout all of the testing work at Good Housekeeping Institute is to test every device so as to duplicate the conditions under which the device will be used by the ultimate consumer, be she intelligent or unintelligent. It has furthermore been the Institute's special province to express to each manufacturer the trend of consumer demand as seen, not only through the Institute's use of appliances, but through the
