Nor is this all that the Indian may teach us as to diet. While at times he eats everything he can lay his hands upon and also eats ravenously, in his normal condition he eats slowly and masticates thoroughly. Since Horace Fletcher wrote his most interesting and useful books on diet and life, the term “fletcherizing” has become almost universal amongst thoughtful people to express mastication to the point of liquifaction. But I was familiar with “fletcherizing” before I had ever heard of Mr. Fletcher. The Indians, with their parched corn, had taught me years before the benefit of thorough and complete mastication. I had gone off with a band of Indians on a hard week’s ride with no other food than parched corn and a few raisins. This was chewed and chewed and chewed by the hour, a handful of the grain making an excellent meal, and thoroughly nourishing the perfect bodies of these stalwart athletes, who never knew an ache or a pain, and who could withstand fatigue and hardship without a thought. [Illustration: MY HAVASUPAI HOSTESS PARCHING CORN IN A BASKET.] A marked and wonderful effect of thorough mastication is that it decreases the appetite from 10 to 15 per cent, and reduces the desire for flesh meat from 30 to 50 per cent. The more we masticate the less we desire to eat, and the more normal our appetites become. This in itself is a thing to be desired, for it is far easier not to have an abnormal appetite than it is to control it when it has fastened itself upon us. Then, too, while Indians will often eat to repletion, and at their feasts indulge in disgusting gorging, they do know how to fast with calmness and equanimity. I am not prepared to say that they will fast voluntarily--except in the cases of those neophytes who are seeking some unusual powers or gifts from Those Above--yet I do know that several times I have been with them when fasting was obligatory because of the scarcity of food, and they accepted the condition without a murmur. I know a very prominent physician in San Francisco, who has an extensive practice, who pumps the food out of the stomachs of several of his gluttonous patients after their hearty French dinners. He defends his course of procedure by saying that his patients would not listen to him if he counseled fasting for even one meal, yet they are willing to allow him to remove the food after it is eaten, and to swallow some harmless “dope” that he gives them, because that is easy and requires no self-control.
