desires them to possess not only the physical but the mental and
moral benefit, the grace and dignity and self-possession, the courage
and self-reliance, that an erect bearing greatly tends to promote. Let
the teacher give instruction on this point by example and precept.
Show what a correct position is, and insist that it be maintained.
Next in importance to right position are respiration and vocal
culture. The one who sits and stands erect is more likely than others
to breathe properly. But the teacher should impress upon students the
importance of deep breathing. Show how the healthy action of the
respiratory organs, assisting the circulation of the blood, invigorates
the whole system, excites the appetite, promotes digestion, and
induces sound, sweet sleep. This not only refreshes the body but
soothes and tranquilizes the mind. Let exercises in deep breathing
be given, and see that the habit becomes established.
The training of the voice has an important place in physical
development, since it tends to expand and strengthen the lungs, and
thus to ward off disease. To ensure correct delivery in reading and
speaking, see that the abdominal muscles have full play in breathing
and that the respiratory organs are unrestricted. Let the strain come
on the muscles of the abdomen rather than on those of the throat.
Great weariness and serious disease of the throat and lungs may
thus be prevented. Careful attention should be given to securing
distinct articulation, smooth, well-modulated tones, and a not-too-
rapid delivery. This will not only promote health but will add greatly
to the agreeableness and efficiency of the student’s work.
In the study of hygiene the earnest teacher will improve every
opportunity to show the necessity of perfect cleanliness both in
personal habits and in one’s surroundings. The value of a daily
bath in promoting health and in stimulating mental action, should
be emphasized. Attention should be given also to sunlight and
ventilation, the hygiene of the sleeping room and the kitchen. Teach
students that a healthful sleeping room, a thoroughly clean kitchen,
[120]
and a tastefully arranged, wholesomely supplied table, will go further
toward securing the happiness of the family than any amount of
expensive furnishings. That “life is more than food, and the body
is more than clothing” (
Luke 12:23
) is a lesson no less needed now
than when first given by the divine Teacher.
