RULES OF SAVING AND SAFETY
1. Let no family (of five persons) buy meat until it has bought three quarts of milk, the cheapest protein food. Farmers should be urged to meet this demand.
2. Save the cream and butter and eat oleomargarine and vegetable oils. Olive oil or cottonseed oil, taken with cabbage, lettuce, or beet-tops, is excellent food, in many ways imitating milk.
3. Eat meat sparingly, rich and poor, laborer and indolent alike. Meat does not increase the muscular power. When a person is exposed to great cold, meat may be recommended, for it warms the body more than any other food. In hot weather, for the same reason, it causes increased sweating and discomfort. In general, twice as much meat is used as is now right, for to produce meat requires much fodder which might better be used for milk production.
4. Eat corn bread. It saved our New England ancestors from starvation. If we eat it we can send wheat to France. Eat oatmeal.
5. Drink no alcohol. In many families 10 per cent. of the income is spent for drink, or a sum which, if spent for real food, would greatly improve the welfare of the family.
