The soldiers and physiologists are too busy studying indigestion and possible proteid poisoning and what-not-other causes of intemperance, disease, and suffering to ask you to assist in spreading only serious report and right suggestion relative to the importance and purport of the investigation, but it is my privilege to ask it for the general good. * * * * * Just another word of introduction and then will follow some _postintroductory_ coincidences relative to the work in hand, and then an attempt to lay out a ten-page chart of the personal responsibility in the care of the body and the nourishment of the mind by aid of an economic and most satisfactory nutrition, so as to make conservation of energy as easy as possible and life well worth the living. The scientific support from the pens of professional observers is, however, the real meat of the book, for which compiler and reader alike are and should be grateful. * * * * * In serving in the humanitarian ranks in a commonweal campaign one should not need to use the concealment of modesty, nor should he fail to speak with all frankness. What are the motives behind all this energy to reform the eating habits of the people? The question has been so often asked that it is better thus publicly answered. No one concerned in the campaign has any personal monetary interest in any kind of food, prepared or otherwise. The movement began in a suggestion carried by an accidental word given to the author by a friend, an old-time friend in Japan, and a friendship never to be forgotten, as related in the author’s book “Menticulture.” Pursuit of menticulture led further to the discovery that the best mental results could not be accomplished in a body weakened by any indigestion, any mal-assimilation of nutriment, any excess of the waste of indigestion. Then came the quest for the causes of mal-nutrition, which were soon found, by study of the natural sequences and by going behind the hypotheses of text-book authority, to arise in the careless ingestion of food, its neglect in the mouth, and the consequent glut of unassimilable excess within the body, necessitating enormous expense of brain and body energy to get rid of the excess.
