others to a house lacking only a door or two. It takes some thought to put
them together so that we shall have all kinds of parts without a great
many extra ones of certain kinds and not enough of others.

Milk is unique in that it comes nearest of all foods to being a complete
diet in itself. It is like the house with only a door missing. We could be
quite comfortable in such a house for a long time though we could make a
more complete diet by adding some graham bread or an apple or some
spinach.

We all associate milk with cows and cows with farms, but how closely is
milk associated with the farm table? Is it prized as the most valuable
food which the farm produces? Every drop should be used as food; and this
applies to skim milk, sour milk, and buttermilk as well as sweet milk. Do
we all use milk to the best advantage in the diet? Here are a few points
which it is well to bear in mind:

_Milk will take the place of meat._ The world is facing a meat famine. The
famine was on the way before the war began but it has approached with
tremendous speed this last year. Every cow killed and eaten means not only
so much less meat available but so much less of an adequate substitute.
Lean meat contributes to the diet chiefly protein and iron. We eat it
primarily for the protein. Hence in comparing meat and milk we think first
of their protein content. One and one-fourth cups of milk will supply as
much protein as two ounces of lean beef. The protein of milk is largely
the part which makes cottage cheese. So cottage cheese is a good meat
substitute and a practical way of using part of the skim milk when the
cream is taken off for butter. One and one-half ounces of cottage cheese
(one-fourth cup) are the protein equivalent of two ounces of lean beef.
Skim milk and buttermilk are just as good substitutes for meat as whole
milk. Since meat is one of the most expensive items in the food bill, its
replacement by milk is a very great financial economy. This is true even
if the meat is raised on the farm, as food for cattle is used much more
economically in the production of milk than of beef.

_Milk is the greatest source of calcium (lime)._ Lime is one of the
components of food that serves two purposes; it is both building material
for bones and regulating material for the body as a whole, helping in
several important ways to maintain good health. It is essential that
everyone have a supply of lime and particularl
