Another humanitarian movement from which assistance will doubtless come to the crusade against the social evil, is the great movement against alcoholism with its recent revival in every civilized country of the world. A careful scientist has called alcohol the indispensable vehicle of the business transacted by the white slave traders, and has asserted that without its use this trade could not long continue. Whoever has tried to help a girl making an effort to leave the irregular life she has been leading, must have been discouraged by the victim's attempts to overcome the habit of using alcohol and drugs. Such a girl has commonly been drawn into the life in the first place when under the influence of liquor and has continued to drink that she might be able to live through each day. Furthermore, the drinking habit grows upon her because she is constantly required to sell liquor and to be "treated." It is estimated that the liquor sold by such girls nets a profit to the trade of two hundred and fifty per cent. over and above the girl's own commission. Chicago made at least one honest effort to divorce the sale of liquor from prostitution, when the superintendent of police last year ruled that no liquor should be sold in any disreputable house. The difficulty of enforcing such an order is greatly increased because such houses, as well as the questionable dance halls, commonly obtain a special permit to sell liquor under a federal license, which is not only cheaper than the saloon license obtained from the city, but has the added advantage to the holder that he can sell after one o'clock in the morning, at which time the city closes all saloons. The aggregate annual profit of the two hundred and thirty-six disorderly saloons recently investigated in Chicago by the Vice Commission was $4,307,000. This profit on the sale of liquor can be traced all along the line in connection with the white slave traffic and is no less disastrous from the point of view of young men than of the girls. Even a slight exhilaration from alcohol relaxes the moral sense and throws a sentimental or adventurous glamor over an aspect of life from which a decent young man would ordinarily recoil, and its continued use stimulates the senses at the very moment when the intellectual and moral inhibitions are lessened. May we not conclude that both chastity and self-restraint are more firmly established in the modern city than we realize, when the white slave traders find it necessary both forcibly to detain their victims and to ply young men with alcohol that they may profit thereby? General Bingham, who as Police Commissioner of New York certainly knew whereof he spoke, says: "There is not enough depravity in human nature to keep alive this very large business. The immorality of women and the brutishness of men have to be persuaded, coaxed and constantly stimulated in order to keep the social evil in its present state of business prosperity."
