It is not possible to consider the details of the great amount of extremely valuable work accomplished by the scientific departments of the Washington Government and in the individual Agricultural Experiment stations in this country and abroad.
It may, however, be of interest to present the results of a study of the sale of food at the Childs restaurants1 in order to show this principle of caloric feeding, now adopted in hospitals and upon farms, that it may be worked out in the daily life of the people.
(Note that when three portions furnish 2500 calories, one portion affords a good meal. When nine portions furnish 2500 calories, then three portions should form the meal).

The main objection that has been encountered to the sale of food on the caloric basis has been the sensitiveness of the business world to the introduction of a new and unknown quantity. Why not leave well enough alone?
A more highly educated generation will, however, demand that its expenditure of thousands of millions of dollars for food shall not continue to take place in unfathomable depths of darkness.
For the purpose of dealing with the unintelligent masses in actual need of food the writer recommended to Dr. Haven Emerson, the local Commissioner of Health in New York City, that grocers be persuaded to prepare "Board of Health baskets" to provide 10,000 calories daily for a family of 5 at a minimum cost. The occasion was that of a general strike in the cloak.making trade. The baskets were reminiscent of the poorhouse fare in Finland (see p. 351) and should be understood as representing minima for a family out of work. Basket I is not to be commended for constant use over a prolonged period, though Basket II would probably suffice for maintenance and growth during many months.

Soak in water over night. Boil one and one-half hours.
Boil one-half hour.

Rubner1 has set forth his ideas of true reform with regard to the question of the nourishment of the masses. There should be less profit to middlemen. If food must be eaten outside the home, there should be cheap restaurants or public kitchens where nourishing food can be purchased. It is cheaper to cook in one's own kitchen provided the fire that is used for cooking is needed for heating. The personal ownership of a house and garden to the wide-spread extent of such ownership in America must be morally uplifting for a community. For this reason factories should be built in the country. Furthermore, children are more useful in the country than in the city. The cost of rooms in which to live bears an intimate relation to the amount of money available for food. Not only are quarters costly in the town, but many landlords classify children with cats and dogs as undesirable tenants.

The housewife should know about cooking, and both she and her husband should know something of the value of food. The sum wasted for alcoholic beverages would frequently be sufficient to turn the scale in favor of the proper nutrition of the family. Cheaper milk for the babies of the poor and adequate nourishment for school children are important factors in the situation. Rubner regrets that the knowledge of biology, even among the educated classes, is so limited that the science of nutrition appears to them to be wholly useless.
Rubner's words were written in contemplation of a highly developed modern community and before the outbreak of the war. The story of the regulation and conservation of the food supply by the state under scientific direction is yet to be written. An enforced abstinence from alcohol cannot possibly be harmful, but whether the introduction each week of two or three "meatless days" into the regimen of adults, and especially of children, is for their permanent welfare cannot at present be determined. The psychologic factor alone is of too profound significance to give credence to the value of any personal opinion.
As this book goes to press it seems that America herself is certain to face a food shortage before very long. This can be remedied by increasing the number of milch cows and by reducing the livestock raised for meat. The latter would free arable land for the production of grain and potatoes and save, for human consumption, grain fed to steers. It is quite certain that meat in the quantity it is consumed today is entirely unnecessary, and it is susceptible of scientific proof (see p. 312) that mechanical work is more efficiently and economically derived from carbohydrate food than from meat.
