Accustomed to seeing messenger boys engaged during the day in the unobjectionable task of delivering telegrams to residences and business offices, one is likely to regard this service as an occupation quite suitable for children and to give it no further thought. However, the character of the work done by the messenger boy changes radically after nine or ten o'clock at night. At that hour most legitimate business has ceased, and the evil phases of city life begin to manifest themselves. From that time on until nearly dawn the messenger's work is largely in connection with the vicious features of city life. The ignorance of the general public as to the evil influences surrounding the night messenger service is strikingly illustrated by what one Indiana boy told an investigator; he declared that if his father knew what kind of work he was doing, a strap would be laid across his back and he would be compelled to abandon it. But the father did not know; he thought his boy was simply delivering telegrams. The delivery of telegrams forms but a small part of the boy's work at night, because few messages are dispatched after business hours. Instead, calls are sent to the office for messengers to go on errands. The boys wait upon the characters of the underworld and perform a surprising variety of simple tasks; they carry notes to and from the inmates of houses of prostitution and their patrons, take lunches, chop suey and chile con carne to bawdyhouse women, procure liquor after the closing hour, purchase opium, cocaine and other drugs, go to drug stores for prostitutes to get medicines and articles used in their trade, and perform other tasks that oblige them to cultivate their acquaintance with the worst side of human nature. One instance was found in which the boy was required to clean up the room of a prostitute and to make her bed. The uniform or cap of the messenger boy is a badge of secrecy and enables him to get liquor at illegal hours or to procure opium and other drugs where plain citizens would be refused; hence these boys are thrown into associations of the lowest kind, night after night, and come to regard these evil conditions as normal phases of life. Usually the brightest boys on the night force become the favorites of the prostitutes; the women take a fancy to particular boys because of their personal attractiveness and show them many favors, so that the most promising boys in this work are the ones most liable to suffer complete moral degradation.
