"The inference to be drawn from these incontrovertible facts is, that if we, in very early life, teach young children to practice similar exercises, and follow them steadily afterwards, we shall confirm them in excellent health, and prevent the accession of those evils which so often cause deformity to the figure, and destruction to the constitution, at later periods of life. I do not propose to make every boy a soldier, or every girl a dancer upon the stage, but to adopt the principles, by the application of which those persons are trained to the successful practices of their several occupations, and so to modify them, that they may qualify other classes of society to follow their different pursuits with equal success; and I am not without hopes that this undertaking will contribute something towards producing this desirable effect."

Dancing is an exercise which has been practiced by mankind from the most remote ages. With the Egyptians, Assyrians, and Persians, the founders of the three great empires of the ancient world, dancing was the favorite exercise or accomplishment, and the practice was not less prevalent among their successors in power and importance, the Greeks and Romans. The Jews, also, we learn from Scripture, were strongly attached to the exercise at all periods of their history.

At the present day, almost every people that exist, whether barbarous or civilized, has its own form of dancing. It is this universality of the exercise that makes dancing a subject of importance. Being so extensively practiced, it must be the instrument either of good or evil to the human race.

It is one of the most healthful and elegant amusements, and cannot be too highly recommended. Among a rude and dissolute people it may degenerate into something worthy of condemnation; but all the blessings we have are similarly liable to abuse, and it would be most unjust to condemn a cheerful domestic amusement, merely because it has, at times, been degraded by people of low, vulgar, immoral tastes. By all physicians, dancing, when pursued in moderation, is recommended as highly conducive to bodily health; and it may be truly said, that, allied with music, nothing is more conducive to mental health, more calculated to drive away melancholy, and put the whole temper into good humor.

Dancing is the poetry of motion. It must be performed with ease and grace, and always with a perfect regard for propriety of movement.

As an art it is taught by professed masters; and one of the leading rules given to the learner is to raise and lower herself gracefully on the elastic part of her feet, and to keep perfect time to the music. Dancing is really a simple and elegant gliding on the toes, which bend more or less to accommodate the steps, and prevent harsh, ungraceful motion.

The most popular dances of the present day, are, first, the quadrille.

These are of French origin, comparatively tranquil in their character, and generally danced once or more in every party. They are danced by four couples, one standing on each side of a square. There are many sets of quadrilles, the figures in each varying from the others. But there are five figures in each set. The plain, fancy, Lancers, Polka, Mazourka, and German, are among the most popular.

In plain quadrilles, a lady takes no steps, merely walking gracefully through the figures, but her feet must keep perfect time to the music, and she must know the changes of position perfectly.

A quadrille may be very properly described as a conversation dance, as there are long pauses between the figures, when the dancers must have a fund of small talk ready for their partners.
