The policy of the Church from the beginning has been, and now is, opposed to waltzing, so far as it has had power to do so. That particular dance has been excluded from our social gatherings but so strong has been the desire of our young people to indulge in the waltz that it has been considered an act of discretion in some places to permit those in charge of dances to allow the young people a limited number of what is called round dances. . . . It has been considered better to allow a limited number of round dances in our social gatherings which we ourselves control rather than to furnish excuses for our young people to indulge in these dances elsewhere, and for this reason they have been allowed.
