the necessary opportunity to replenish the lungs, so that the speaker
will not suffer from unnecessary fatigue. Needless to say, the habit
should be formed of breathing through the nose when in repose.

There is a voice of unusual roundness and fulness known as the orotund,
which is indispensable to the public speaker. It is simple, pure tone,
rounded out into greater fulness. It is produced mainly by an increased
resonance of the chest and mouth cavities, and a more vigorous action of
the abdominal muscles. It has the character of fulness, but it is not
necessarily a loud tone. It is in no sense artificial, but simply an
enlargement of the natural conversational voice.

The use of the orotund voice varies according to the intensity of the
thought and feeling being expressed. It is used in language of great
dignity, power, grandeur, and sublimity. It is appropriate in certain
forms of public prayer and Bible reading. It enables the public speaker
to vary from his conversational style. It gives vastly increased scope
and power, by enabling the speaker to bring into play all the resources
of vocal force and intensity.

Where resonance of voice is lacking, it can be rapidly developed by
means of humming the letter _m_, with lips closed, and endeavoring to
make the face vibrate. The tone should be kept well forward throughout
the exercise, pressing firmly against the lips and hard palate. Later
the exercise may begin with the humming _m_, and be developed, while the
lips are opened gradually, into the tone of _ah_, still aiming to
maintain the original resonance.

The speaking voice is capable of most wonderful development. There is a
duty devolving upon everyone to cultivate beauty of vocal utterance and
