In no essential respect does the conduct of a tenement vice resort differ from that of the parlor house previously described. Prices are of the same range, from fifty cents to ten dollars; occasionally twenty-five dollars may be demanded. The same pretense of medical examination is made. The same advertising devices are employed. A madame who conducts a prosperous business in a tenement in West 58th Street sends a letter to her former customers announcing the removal of the "library."[38] The use of the word "library" to indicate the resort and of "books" to indicate inmates is a popular one. Another madame urges her former patrons to renew their "membership in the library"; "new books," she asserts, are "on file in our new quarters." Still another enterprising promoter invites men to her place of business by saying, "Please call as I have a _new_ member in the lodge." Similarly, business is procured through the same agents utilized by the parlor house--runners, bartenders, cabmen and chauffeurs. Where several establishments are conducted in one apartment building, elevator boys are given liberal tips by rival madames for "steering" callers to their flats. Often the madames or selected inmates go to public places or on the streets to solicit men. Sometimes they visit a large office building and under some pretext seek an interview with the heads of firms or with managers, and leave their cards. One day a young lawyer received a letter asking him to call at a certain address in Harlem on a matter of business. Though he did not recognize the name, he kept the appointment. He was dumfounded to find the supposed client a madame who had four inmates in her resort. Liquor is more largely sold in tenement resorts than in parlor houses; the prices are usually the same, five dollars for a small bottle of wine, two dollars for a round of beer. In many of the resorts in tenements drugs are used by the inmates and sold to customers. For instance, the investigator of a resort on West 111th Street found several men smoking opium. In another flat, on West 37th Street, one of the colored inmates was snuffing cocaine. In a tenement on West 39th Street there is an opium "joint" on the second floor where prostitutes "smoke." Some of the girls spend five and six dollars a day in this place. A girl who solicits on the street for a vice resort in a tenement on West 38th Street is a "dope fiend," and the madame of a flat on West 43rd Street, where there are four inmates, is addicted to the opium habit. Not infrequently an apartment is utilized as a call-house: girls, not living on the premises, are summoned by telephone when customers arrive. Additional recruits are also procured by call, when needed. The "call" is sometimes a half-way stage for the working girl on the road to complete prostitution. One day the madame of a call-house on West 58th Street received a special delivery letter, the number of which was 14.446--9, reading as follows:
