In order to escape the surrounding temptations it is necessary to have always in mind protective counter-suggestions which intelligently make use of the abundant and easy supply but limit the intake to the needs of the body as expressed by appetite when permitted to discriminate in its natural deliberate manner, and which only keeps pace with the natural dissipation of taste in the process of requisite insalivation. The chewing practice is but a means to this natural end, but it is a most important means, the same now as when teeth were used instead of patent grinders, and when taste took the place of spices and sauces and manufactured its own delights by the chemical action of saliva. Among the Zuni Indians, observed by even recent travellers, it is the custom of the young girls of the _pueblos_ to masticate wheat up to a given point of sweetness of taste and then to withdraw it from the mouth and collect it in a wooden dish until a sufficient quantity is secured, when the jaw-ground and saliva-sweetened "mess" is baked in the sun or by fire and becomes the "sweet cake" of the family. The change of the starch of the wheat or corn into sugary dextrose by the action of saliva, which is necessary to be done somewhere in the alimentary canal before it is assimilable nutriment, gives the sweet-cake quality to the food which is the dietary delicacy of these primitive people. By proper insalivation we perform the delectable service for ourselves instead of having it done for us by good young teeth aided by healthy saliva furnished by beautiful feminine assistance. "FLETCHERISING" FOOD WHAT IT REALLY MEANS The term "Fletcherising," or "Fletcherizing," as applied to food has come into use without the suggestion of the nominee to a new filtering fame, and promises to spread; hence it is well to explain just what the term means. Under the so-called "Fletcherizing" process, the mouth becomes a filter with most facile appliances for protecting the delicate alimentary canal from straining and poisoning. Instead of the "Pasteur Filter" for the purification of water and the "pasteurisation" of foods by sterilisation, the "Fletcher Filter" both separates and prepares whatever is given it to treat more perfectly than any mechanical or chemical device can do. Dr. Kellogg appears in evidence often in this volume, and also with much appreciated strength of indorsement in the "A. B.-Z. of Our Own Nutrition"; but it is because he knows the value of the discovery of the natural food filter, has enormous chance to test it practically, and generously assists the reform with the might of his conviction. Hence the author has still another letter of his in hand from which to quote. "BATTLE CREEK, MICH., Oct 26, 1903. "MR. HORACE FLETCHER, NEW YORK. "DEAR FRIEND:--I have yours of October 4th.
