7. Switch control of motor, clutch control of tub and wringer. 8. Height that will obviate stooping. 9. Design to insure efficiency. 10. Motor and switch insulation. 11. Materials and workmanship that insure durability. 12. A water outlet that allows rapid running off of water. 13. Threaded outlet to allow for connection. 14. All handles and levers to be easy to grasp and to turn by wet hands. 15. Tub body slightly off the level to allow for draining. It is easy to sell a refrigerator that has a sightly appearance, that is equipped with a sanitary seamless lining and that is marked with a price that spells to the woman good workmanship. But it is only actual use in storing food that develops the fact that the insulation is of sufficient quantity and is assembled with high grade construction, or that cheap material and workmanship have been substituted. The service that can be obtained from the appliance after it is marketed is of the utmost importance for the manufacturer to learn. _It is peculiarly impossible to sell and "forget" any product sold to women._ THE WOMAN'S VIEWPOINT ON MATERIALS USED IN CONSTRUCTION. Undoubtedly a phase of manufacturing that acutely interests the average manufacturer deals with the selection of the materials that are to be used in the construction of his product. Too often the person who selects these materials fails to take into account the fact that women are almost fanatically intolerant of two things, rust and discoloration. It may be but one bolt that can rust, but women under our observation have utterly condemned a washing machine for which they paid from $125 to $165 because of this one bolt alone. We have heard them further condemn a machine because of the difficulty of keeping it polished. It is not purpose, we are convinced, but it must be carelessness on the part 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.
