The prostitute herself frequents the hairdressing and manicure parlors, popular with her for two reasons: first, because here she makes herself "beautiful" under the hands of the proprietor, and second, because through the operator she learns of resorts where she may earn "better money." The imparting of such information is a part of the hairdresser's trade. She is the fount of knowledge on this subject; "swell" madames patronize her place, urging her to send them attractive girls. If the right girls do not come in, she advertises in the papers, using her "parlor" as a decoy. Her husband--if she has one--may be a thrifty man who mingles with his wife's customers, selling them attractive hats or suits, and other things, and finally acting as their bail bondsman if they are arrested and brought to court. At least one such husband has grown wealthy in the business. Such a hairdressing and manicure parlor, for example, is conducted on Sixth Avenue.[84] The woman caters only to prostitutes; and part of her business is to find out if any of her customers are dissatisfied with their present places or if they are not attached to any resort. In either event, she offers to send them to find a place where they can earn more money. One day a woman having her hair shampooed in this parlor actually heard the proprietor send girls to different vice resorts. She advertises in the daily press for help. For instance, on Saturday, April 6, 1912, a daily paper contained the following advertisement under "Female Help Wanted": "Hairdresser and manicure wanted, experienced. Apply ----, ---- Sixth Avenue."[85] Pool rooms and cigar stores offer peculiar facilities for young boys of the neighborhood to become acquainted with the life of the underworld. Even before leaving school, boys often frequent them; soon some of them join little cliques and gangs formed by the criminal element. They become pickpockets or ordinary crooks. If endowed by nature with large muscles and an instinct for fighting, they become preliminary boxers and gradually develop into the gang members or political guerillas who do such valiant service at the polls on primary or election day. From the ranks of these the pimp is developed. As neighborhood boys they have little difficulty in securing girls who, like themselves, are adventurous, or already immoral. It therefore becomes easy either to trap a girl and ruin her, or to "break in" the already immoral girl to a life of professional prostitution under protection.
