In writing this book, my aim has been (1) to give information which will guide householders in selecting and installing the best cooking and heating devices, and in using them with the greatest economy of fuel and safety against accidents; (2) to explain the construction of lighting fixtures and how to determine the amount of light for health needed in various places; (3) to explain the principles of cooling; (4) to show how to make small repairs which save plumbers' bills; (5) to guide in the choice and care of laundry appliances and cooking utensils; (6) to familiarize women with the construction of electric, acetylene and gas plants and engines, and (7) to furnish tables of measure often needed for reference.

There is a lack of material of this type which is non-technical enough for the use of home economics students and housewives. The material which I have organized applies directly to the appliances with which women work and is of a nature to fill their need in this field.

The book is designed as a text for senior-high school and junior-college classes, as well as for the needs of home-demonstration agents, housewives and other women.
