Both men and women have been needed in the investigation of dance halls and both have responded to the need, comparing notes and conferring on the general situation. The men can better gain the confidence of the male patrons, follow them to their resorts and learn whether the dance hall is allied with vicious interests. On the other hand, the women can better gain the confidence of their own sex and find out what motives actuate girl patrons in frequenting such places, in drinking the liquor that is almost invariably to be found at dance halls, and in succumbing to the temptations that are offered at the close of the dance. Among the skillful and ingenious women investigators of dance halls, Julia Schoenfeld, now field secretary of the National Playgrounds Association, perhaps takes first rank. Her study of conditions in New York City, which she made under the most difficult requirements, paved the way for the municipalization or municipal control of the dance halls which has become an accomplished fact, if on a small scale at present. Mrs. Charles Israels of New York and the members of the Women’s Municipal League, with the facts obtained by Miss Schoenfeld, were able to start a substantial movement toward the extension of municipal functions in New York to cover the recreation of dancing, not entirely, of course, but to the extent of providing greater facilities for this recreation under careful supervision and with drinking entirely eliminated. One hears women in New York state as their hope that before long their city will boast a municipal dancing master who will preserve for the foreign colonies, that exist in such, abundance, their old-country folk dancing, who will have facilities for providing inspiring music and halls where the young may dance with safety and freedom. In spite of good beginnings in this direction, however, New York has been slow to follow the excellent example set by Chicago with its system of field houses for dancing in the public parks. The evil resulting from the commercialization of the dance hall can be destroyed only by eliminating the element of profit-making. Municipalization is the remedy. Well-informed women are now arguing this. Mrs. Louise de Koven Bowen, head of the Juvenile Protective Association of Chicago, is one of the women who are educating the public to a realization of the fact that profit-making from dancing must be abolished. In a little pamphlet entitled “Our Most Popular Recreation Controlled by the Liquor Interests,” she presents a study of the public dance halls of Chicago which is most convincing in its plea for a department of recreation in Chicago.
