                      NATURE'S GYMNASTIC Rubbing their sleepy eyes with lacy
                     wrists,And doubling overhead their little
                     fistsIn backward yawns. KEATS. DELICIOUS, isn't it ? The rosy little
                     fellows, doubling up their tiny fists and
                     stretching out their little arms and legs, one
                     this way, one that, as gracefully said
                     unconsciously as gods or animals. Enjoying it,
                     too, no doubt, as the sympathetic poet must have
                     felt, to put such a sense of simple delight into
                     the lines. We also enjoy it, when we are willing
                     to yield ourselves lazily to the impulse, making
                     no effort to hurry through with it or to choke
                     it in its inception. Nothing man does in life is more perfectly
                     instinctive and natural than yawning. Although
                     but a temporary tendency, the impulse is, for
                     the time being, almost as irresistible as the
                     desire to breathe. Yet in the economy of nature
                     it has but one use and one purpose: it is a
                     gymnastic. When the body has lain motionless for
                     some time, as in sleep, or when the powers are
                     at low ebb through fatigue, drowsiness, or
                     ennui, and something is required to restore the
                     system to a state of general activity, nature
                     provides this involuntary inclination, with its
                     graduated series of movements, called yawning.
                     Nature's gymnastic, it embodies all the laws of
                     growth needed for movements that are to give
                     physical growth and refreshment, and some of the
                     laws which are necessary to the higher growth,
                     so-called, of the emotions and the
                     intellect. A good yawn is always slow, and the best
                     uses every articulation in the body probably
                     every muscle-possibly refreshes every nerve. Not
                     all at once or in jerks, but slowly, in perfect
                     successions and rhythms, with the best possible
                     breathing. Certainly no gymnast, with the single
                     exception of Francois Delsarte, ever so arranged
                     the same expenditure of force, nervous and
                     muscular, as to result in an equal amount of
                     invigorating effect upon the system. Succession, opposition, and parallelism
                     these are the three orders of motion used in
                     yawning. The primary motion is probably that
                     moving or pulling against the motionless, which
                     results in the stimulation of the motionless and
                     its consequent antagonistic action. This we call
                     opposition. But since this primary activity
                     takes place in the internal organs, and is thus
                     concealed from the casual or unpractised
                     observer, we can best begin in the present study
                     with those successions which it generates.Now, what does the ordinary onlooker see in
                     the progress of a yawn? At the same time that the muscles of the
                     throat are stretched, the upper eyelid begins to
                     droop, but not as in sleep, for the eyeball
                     wishes to roll upward, rousing the lower lid to
                     action and making it present some opposition to
                     the downward pull of the muscles of the cheek
                     when the jaw drops. Similarly, the contracted
                     eyebrow presents something for the upper lid to
                     pull against when it begins to close upon the
                     eye. The whole face seems now to be struggling
                     to prevent the shutting of the eyes, one set of
                     muscles acting in opposition to another. In this
                     way a perfect means of refreshment has been
                     supplied to the face by the muscular activities
                     passing over it in succession. The blood has
                     been brought to the surface, and a reactionary
                     stimulant sent back to that intimate friend of
                     the face, the brain. So far, at least, the movement has conformed
                     to the definition of a perfect gymnastic, viz.,
                     the greatest motion with the least motive. For
                     the better the gymnastic, the more perfectly at
                     rest are the higher orders of nervous activity,
                     and the motive force the more completely
                     supplied by the automatic processes of the mind,
                     rather than the voluntary. All parts of the body axe alike refreshed by
                     a perfect gymnastic. We have seen the face
                     moving one muscle alter another ; previous to
                     this, however, the throat was stretched, and
                     even before this all the breathing muscles,
                     especially the internal ones; and, now the
                     increased activity of the circulation furnishes
                     a stimulant to the brain, making the automatic
                     impulse still stronger than before and the yawn
                     is either repeated or continued. If continued, we notice that the head begins
                     to roll on its most habituai and instinctive
                     lines of motion, sometimes pulled back in
                     opposition to the opening of the jaw. The
                     muscles of the neck having by this means been
                     used, another stimulating wave of circulation is
                     sent back to the brain, and the ganglia that
                     govern the muscles of the neck and chest are
                     aroused. And now the chest muscles contract and
                     we see the ribs raised, sometimes to such an
                     extent as to stimulate the diaphragm and other
                     interior muscles of breathing, which are so
                     attached as to fix or move alternately the ribs
                     or arms. By this time still further automatic
                     stimulus has arisen by means of increased
                     circulation, and motion is communicated to the
                     entire frame. The arms rise slowly and
                     rhythmically and are stretched above the head,
                     or sometimes waved in the air. At this point we
                     must have readied the "going-on-all-fours" stage
                     of nervous excitation, for legs and arms now
                     stretch and pull, first in succession (the legs
                     last), then in opposition, each pulling against
                     the other. A tendency to do as one's neighbors
                     do causes each new muscle to combine in action
                     with one of those already moving, and then
                     another with this, and so on over the whole
                     body. Observe that the external manifestation of
                     this succession of motion originates always in
                     the face and extends itself over the whole body
                     like a wave, reaching the feet last. We shall
                     afterward find that this law of sequence is trie
                     of all natural and beautiful on. Observe also that the time is always slow
                     and soothing, and without having a positive
                     recurrent beat, there is still something
                     rhythmic in the action. There is never anything
                     that in the remotest degree resembles a jerk. On
                     the contrary, the time is measured (metre), and
                     the motion of all the parts harmonic. Contrast
                     the restful movement of the yawn with the
                     ungraceful and fatiguing jerkiness of the
                     mind-directed motions often used in work,
                     gesture, and gymnastics. The order of succession
                     in which each muscle takes up its part of the
                     work, is one element in the perfect harmony
                     which should prevail. Another is that the work
                     be proportionally di vicled among all the
                     muscles, so that each has only a pleasurable
                     amount and knows just when to begin, and acts
                     only in its own turn and in its own time. How does each muscle know its own time?How does each pendulum know its own
                     time? For the purpose of the present paper, it may
                     be sufficient to say that the laws of vibration
                     are common to all physical objects that the wave
                     current which incites the muscle to activity,
                     and the chemical changes in the nerves that
                     transmit that current, are vibratory. The
                     application of force from the muscles to tue
                     bones, making each bone a lever or a pendulum,
                     is still all in obedience to the laws of
                     gravitation. Hence, every bone and mus1e has a time ratio
                     peculiar to itself. This is the natural,
                     automatic period of motion most easy, most
                     expressive, and most economical. And wonderful
                     as it makes the structure of the human body
                     appear (though it may readily be shown how by
                     natural selection this state of things would
                     come about), all the different time-ratios are
                     harmonic that is to say, so intricately
                     inter-dependent that each (when in automatic or
                     other perfect use) is in relation to every
                     other. All breaks in this harmony are caused by
                     the interference of ignorant mentality or of
                     abnormal (sinful) motives. Unnatural habits,
                     produced in the first place by a false social
                     environment, cause injury to some organs by over
                     action, while others sink into decay through
                     idleness or ennui. One of the simplest, because most purely
                     physical and automatic, of the harmonies of the
                     body is seen in the yawn. If the step from its
                     simplicity of purpose to the complexity of the
                     possible mental and emotional uses of the body,
                     appears a great one, the construction of an
                     intermediary scientific gymnastic may prove the
                     existent connection. Why not adopt yawning itself as our
                     gymnastic, since it so perfectly ifiustrates the
                     laws of the body? There are several reasons why
                     other movements are better. For one, the yawn is
                     too catching; it would too readily become a it,
                     and might appear on inconvenient occasions.
                     Doubtless, within limits, it could be encouraged
                     usefully. It would be funny, at least, to see
                     fifty boys in a school, or a thousand soldiers
                     in a regiment, all taking exercise in this
                     manner! If we examine many accepted systems of
                     gymnastics, we shall find in most that the
                     rhythms of the body are wholly disregarded, and
                     the conventionalized rhythm of a musical
                     instrument is substituted. Further, that the
                     orderly and graceful arrangements, successions,
                     and oppositions of the movements and attitudes
                     of the members, are either neglected or
                     subordinated to the relations of individuals to
                     each other, and of all the class to the
                     floor! For example, in teaching walking to our boys
                     or soldiers, all must, for the sake of the
                     uniformity of the whole, take steps of the same
                     length, regardless of the different development
                     of the inchvidual leg-pendulums; so that while
                     the mass moves well, only a few individuals are
                     able to do so. This may be a necessity in
                     armies; but it is a poor standard for personal
                     culture. Yet the teaching of marching is about
                     the only teaching that exists, of that superb
                     gymnastic and accomplishment graceful
                     walking. A gymnastic, while stimulative and
                     developing to the body, might also be
                     educational. Then why spend time and effort
                     merely to accelerate the circulation and
                     increase the bulk, when at the same time bulk of
                     better shape could be obtained by means of a
                     gymnastic that, starting with the laws of the
                     body's growth, would end in those of the soul's,
                     including development in all forms of grace and
                     charm, of motion and expression, through all the
                     varied acts and relations of social
                     existence. Panic,
