The Grand Old Man of Democracy in England, William Ewart Gladstone, had had his say on the same subject some years before, and will be known to the future of physiological fitness more permanently on account of his glorification of Head Digestion of food than for his Liberal Statesmanship. In like manner, Mr. Rockefeller will deserve more gratitude from posterity for having prescribed the secret of highest mental and physical efficiency in thirty-three words, than for the multiple millions he is dedicating to Science and Sociological Betterment. It will be interesting, however, to seekers after supermanish health and strength to know how the author took the "straight tip" of Mr. Gladstone, and "worked it for all it was worth" until Mr. Rockefeller referred to the process of common-sense involved as "Fletcherizing." I assure you it is an interesting story. It has taken nearly fifteen years to bring the development to the point where Mr. Rockefeller, who is carefulness personified when it comes to committing himself for publication, is willing to express his opinion on the subject. It has cost the author unremitting, completely-absorbing, and prayerful concentration of attention, and nearly twenty thousand pounds sterling ($100,000), spent in fostering investigations and securing publicity of the results of the inquiries, with some of the best people in Science, Medicine, and Business helping him with generous assistance, to accomplish this triumph of natural sanity. In addition to other co-operation, and the most effective, perhaps, it is appropriate to say that there is scarcely a periodical published in all the world, either technical, news-bearing, or otherwise, on the staff of which there has not been some member who has not received some personal benefit from the suggestions carried by the economic system now embodied in the latest dictionaries of many nations as "Fletcherism." The first rule of "Fletcherism" is to feel gratitude and to express appreciation for and of all the blessings which Nature, intelligence, civilization, and imagination bring to mankind; and this utterance will be endorsed, I am sure, by the millions of persons who have found economy, health, and general happiness through attention to the requirements of dietetic righteousness. It will be especially approved by those who, like Mr. Rockefeller, gained new leases of life after having burned the candle of prudence at both ends and in the middle, to the point of nearly going out, in the struggle for money.
