possess real sustaining power and supply the tissues with the necessary
building material; and this truth points out that there are facts and
principles that must be known in order that the proper selection of food
may be made, that it may be so prepared as to increase its value, and
that economy in its selection, preparation, use, and care may be
exercised.

2. Probably the most important of these principles is the _cooking of
food_. While this refers especially to the preparation of food by
subjecting edible materials to the action of heat, it involves much
more. The cooking of food is a science as well as an art, and it depends
for its success on known and established principles. In its full sense,
_cookery_ means not only the ability to follow a recipe, thereby
producing a successfully cooked dish, but also the ability to select
materials, a knowledge of the ways in which to prepare them, an
understanding of their value for the persons for whom they are prepared,
and ingenuity in serving foods attractively and in making the best use
of food that may be left over from the previous meals, so that there
will be practically no waste. Thus, while cookery in all its phases is a
broad subject, it is one that truly belongs to woman, not only because
of the pleasure she derives in preparing food for the members of her
family, but because she is particularly qualified to carry on the work.

3. The providing of food in the home is a matter that usually falls to
the lot of the housewife; in fact, on her depends the wise use of the
family income. This means, then, that whether a woman is earning her own
livelihood and has only herself to provide for, or whether she is
spending a part of some other person's income, as, for instance, her
father's or her husband's, she should understand how to proportion her
money so as to provide the essential needs, namely, food, clothing, and
