"I appreciate very much your offer to send me a memorandum of the work done in Cambridge, also a plan of the work at Yale. You have had a most interesting experience with eminent physiologists, and it has led you deep into the question of nutrition. I shall appreciate very much suggestions from you with reference to subjects for experimental work, and other suggestions which may occur to you respecting the methods, etc. I am sure your wide experience will be a great help to us. The more I test your ideas the more confidence I have in them. "What you say about the wonderful effect of mastication is certainly correct. I observed it right away as soon as I began to practise _Fletcherizing_. By the way, I wrote an article for the last number of my journal, GOOD HEALTH, about "Fletcherizing" food, and I see our colleagues are already taking it up. One of my most able associates, Dr. J. A. Read, who has charge of our sanitarium in Philadelphia, gave a lecture last Thursday night to his patients on "Fletcherizing" food, and his audience was greatly interested. I am sure you deserve to have your name immortalised, as Pasteur's has been. I mention "Fletcherizing" in almost every lecture I give to our patients. I think most of our patients are "Fletcherizing" and are getting great good from it, also a large proportion of our six hundred nurses and other employees. "Awaiting a letter of suggestions at your convenience, I remain, "As ever your friend, "(Signed) J. H. KELLOGG." "Fletcherizing" does not consist only and merely of careful chewing. Careful chewing, with cheerful attention, will secure the comminution, insalivation, and all necessary chemical preparation for perfect digestion, and will separate hard and indigestible matter from the food mass put into the mouth for treatment; but it is the whole environment of the act which counts the best results. Cheerfulness is as important as chewing; and if persons cannot be cheerful during a meal they had better not eat. Not eating will not hurt them in the least, but lack of cheerfulness will defeat the object of the meal by causing more or less indigestion; and hence it not only _does no good to eat when not cheerful, but actually does harm_. Haste and lack of cheerfulness are about the same in effect on digestion. You have no idea how much real nutriment you can get into your system in five minutes if you are industrious with your munching and are cheerful about it; so don't hurry when you have full ten minutes, or perhaps twenty minutes, for taking nourishment. You cannot go faster than Nature will let you, and it is profitable to study Nature and watch her constantly for her proper cue. Don't try to get ahead of her or you may sink in mud or into deep water.
