After giving consideration to various methods that could be used for the purpose of stimulating this little organ, the thyroid gland, I finally concluded as the result of prolonged experimentation that the exercises illustrated in this chapter can most thoroughly be depended upon for producing results. All movements here described have proved effective in imparting to the neck a full, arched, well developed appearance, but I have given especial attention to the active use of the muscles on the back of the neck. Nearly every movement which to a certain extent develops these muscles is inclined to stimulate the thyroid gland. The more special movements for this purpose are indicated in the various illustrations accompanying this chapter. This development of the back of the neck always indicates great vitality, because definite proof is thereby given that the spine is unusually strong and is maintained in a position favorable to the functioning of all the organs of the body. Many of the movements illustrated are but slight in character, but they are the more adaptable because of this. No matter where you may be, whether walking along the street, conversing with a friend, or sitting at a desk, they can be practiced quietly without attracting attention. Furthermore, it is absolutely essential that an erect position of the spine be kept in mind continually. You should begin every morning to hold the spine straight and erect, and each day should represent an increment of success in the struggle finally to maintain involuntarily this position of the body. On arising in the morning, practice some of the exercises illustrated in this chapter for stimulating the thyroid gland, being careful to perform them just as instructed in each illustration. Whenever you are unoccupied during the day, it is a good plan to practice these movements occasionally, as they will assist you materially in maintaining the spine in that erect position which I found so important at the beginning of my vocal studies. The most important movement is to bring the chin downward, inward, and backward as far as possible, endeavoring to arch as much as you can the back of the neck. You may have to practice a long while before you notice an outline that will in any way resemble an arch in the back of your neck, but all this work you can be assured will be of decided benefit to you. And, whether or not you attain the desired arch, you can be assured of benefits that will be worth all your efforts. When you make these movements properly, there is no necessity for trying to bring the chest out or the shoulders far back. The simple movements of the neck alone as described, if properly performed, will fulfill all requirements. For these movements tend mechanically to raise and arch the chest and to throw the shoulders far backward. Remember also the necessity, when taking these movements, of keeping the abdominal
