The almost phenomenal circulation of “Menticulture” for a book of its kind, and a somewhat smaller interest in the books on nutrition and the appeal for better care of the waifs of society, showed that most persons wished, like the author, to find a short cut to happiness by means of indifference to environment, both internal and external, while habitually sinning against the physiological dietetic requirements of Nature. In smothering worry and guarding against anger the psychic assistance of digestion was stimulated and some better results were thereby obtained, but not the best attainable results. Living is easy and life may be made constantly happy by beginning right; and the right beginning is none other than the careful feeding of the body. This done there is an enormous reserve of energy, a naturally optimistic train of thought, a charitable attitude towards everybody, and a loving appreciation of everything that God has made. Morbidity of temperament will disappear from an organism that is economically and rightly nourished, and death will cease to have any terrors for such; and as _fear_ of death is the worst depressant known, many of the _worries_ of existence take their everlasting flight from the atmosphere of the rightly nourished. The wide interest now prevalent in the subjects treated in The A. B. C. Life Series is evidenced by the scientific, military, and lay activity in connection with the experiments at the Sheffield Scientific School of Yale University and elsewhere, as related in the “A. B.-Z. of Our Own Nutrition” and in “The New Glutton or Epicure” of the series. The general application is more fully shown, however, by the indorsement of the great Battle Creek Sanitarium, which practically studies all phases of the subject, from health conservation and child saving to general missionary work in social reform.
