An indispensable feature of the dancing academy is the "spieler." This is a young man whose strongest recommendation is that he is a skilled and untiring dancer. The business of the spieler is to look after the wall-flowers. He seeks the girl who sits alone against the wall; he dances with her and brings other partners to her. It would not do for a place to get the reputation of slowness. The girls go back to those dance halls where they have had the best time. The spieler is not uncommonly a worthless fellow; sometimes he is a sinister creature, who lives on the earnings of unfortunate girls. The dance hall, and especially the dancing academy, because of the youth of many of its patrons, is a rich harvest field for men of this type. Beginning with the saloon dance hall, unquestionably the most brutally evil type, and ending with the dancing academy, where some pretense of chaperonage is made, the dance hall is a vicious institution. It is vicious because it takes the most natural of all human instincts, the desire of men and women to associate together, and distorts that instinct into evil. The boy and girl of the tenement-dwelling classes, especially where the foreign element is strong, do not share their pleasures in the normal, healthy fashion of other young people. The position of the women of this class is not very high. Men do not treat her as an equal. They woo her for a wife. In the same manner the boy does not play with the girl. The relations between young people very readily degenerate. The dance hall, with its curse of drink, its lack of chaperonage and of reasonable discipline, helps this along its downward course. Sadie Greenbaum, as I will call her, was an exceptionally attractive young Jewish girl of fifteen when I first knew her. Although not remarkably bright in school she was industrious, and aspired to be a stenographer. She was not destined to realize her ambition. As soon as she finished grammar school she was served, so to speak, with her working papers. The family needed additional income, not to meet actual living expenses, for the Greenbaums were not acutely poor, but in order that the only son of the family might go to college. Max was seventeen, a selfish, overbearing prig of a boy, fully persuaded of his superiority over his mother and sisters, and entirely willing that the family should toil unceasingly for his advancement.
