Often the only recreation possible for young men and young women together is dancing, in which it is always easy to transgress the proprieties. In many public dance halls, however, improprieties are deliberately fostered. The waltzes and two-steps are purposely slow, the couples leaning heavily on each other barely move across the floor, all the jollity and bracing exercise of the peasant dance is eliminated, as is all the careful decorum of the formal dance. The efforts to obtain pleasure or to feed the imagination are thus converged upon the senses which it is already difficult for young people to understand and to control. It is therefore not remarkable that in certain parts of the city groups of idle young men are found whose evil imaginations have actually inhibited their power for normal living. On the streets or in the pool-rooms where they congregate their conversation, their tales of adventure, their remarks upon women who pass by, all reveal that they have been caught in the toils of an instinct so powerful and primal that when left without direction it can easily overwhelm its possessor and swamp his faculties. These young men, who do no regular work, who expect to be supported by their mothers and sisters and to get money for the shows and theatres by any sort of disreputable undertaking, are in excellent training for the life of the procurer, and it is from such groups that they are recruited. There is almost a system of apprenticeship, for boys when very small act as "look-outs" and are later utilized to make acquaintances with girls in order to introduce them to professionals. From this they gradually learn the method of procuring girls and at last do an independent business. If one boy is successful in such a life, throughout his acquaintance runs the rumor that a girl is an asset that will bring a larger return than can possibly be earned in hard-working ways. Could the imaginations of these young men have been controlled and cultivated, could the desire for adventure have been directed into wholesome channels, could these idle boys have been taught that, so far from being manly they were losing all virility, could higher interests have been aroused and standards given them in relation to this one aspect of life, the entire situation of commercialized vice would be a different thing.
