Experience has proved that the respiratory organs are susceptible of a high degree of development, and it is well known that the strength of the voice depends on the capacity, health, and action of those organs. It is therefore of paramount importance that elocutionary culture should be based on the mechanical function of respiration. And while the elocutionist trains his pupils in such breathing exercises as are above named, he is at the same time giving the very best part of physical education; for the amount of vital power, as well as the amount of vocal power, depends upon the health and vigor of the respiratory process. Few are aware how much may be effected by these exercises, judiciously practiced, in those constitutions where the chest is narrow, indicating a tendency to pulmonary disease. In all such cases, regularly repeated deep inspirations are of the highest value. It should be observed that these exercises are best performed in the open air, or, at least, in a well-ventilated room, the windows being open for the time. But no directions however wise or minute, can supersede the necessity of a competent teacher in this branch of physical and vocal training, and I cannot dismiss this topic without expressing my high appreciation of the value of the labors of that great master of the science of vocal culture, Prof. Lewis B. Monroe, of Boston, who is probably unsurpassed in this, or any other country, as a practical teacher of the mechanism and physiology of speech. Already the benefit of his instruction in this department of education is widely felt, and I omit no opportunity to advise teachers to avail themselves of a longer or shorter course of his admirable training. For if there is any accomplishment which a teacher should be unwilling to forego, it is that, of skill in elocution. ARTICULATION. A good articulation consists in giving to each letter its appropriate sound, and to each syllable and word an accurate, forcible, and distinct utterance, according to an approved standard of pronunciation.
