And this monster is hydra-headed. Stamp it out in one place and it immediately reappears in another. Send a "manager" to prison once, twice, ten times, and the minute the prison doors are open he is back at the old stand doing business. Something of the tremendous efforts being put forth to stamp out this evil may be gained from the headlines of this story, where the strenuous work of Detective Wooldridge of Chicago is summarized. Chicago has been and is today infested by a formidable community of matrimonial agencies who invade all ranks of life. They promote many specious schemes to lure the elusive dollar from the pockets of unwary victims. These operatives are sharp, smooth and unscrupulous--the most dangerous of criminal perverts. Were the census enumerators of the United States to compile a list of the "sucker" public the gullible ones would aggregate tens of millions. There is not a township in this great nation that does not contain its portion of confiding persons who are ready to believe anything, from the rankest catch-penny advertisement to a fallacy in theological dogma. They are willing to open up their hearts to unknown matrimonially inclined correspondents; to accept as gospel the incredible statements of impostors and to pay out money gained by hard toil for something which the reason of a child should tell them it is beyond the power of man to provide. They are easy prey alike to religious and political impostors and unscrupulous adventurers. Investigations for years past into the innermost secrets of swindlers, and the observations incidental to official experience disclosing how victims are drawn into the net of the grafter, impel the belief that the faith of many persons passes beyond the bounds of credulity into the domain of imbecility. Men and women who are engaged in promoting matrimonial agencies are guilty of crime. It is opposed to the fundamental principles of society. Such a practice should under no circumstances be tolerated. It is inconsistent with the highest ideals of what should constitute the proper marriage relations. HUMAN DERELICTS ARE DUPES. Human derelicts of a low mental caliber are the dupes of these matrimonial agencies. Few people know that such schemes as these are carried out. Few know that advertisements by men of wealth, women of culture and pretty widows who seek matrimonial alliances are merely means by which scoundrels get a revenue. MATRIMONIAL AGENTS' METHODS. To describe adequately the technicalities of the marriage agencies and bureau swindlers' methods would be impossible without presenting actual copies of documents necessary to the system. Early in the investigations the discovery was made that the scores of matrimonial agencies, "introduction bureaux" and "marriage clubs" were using practically the same literature. Few departed from the stereotyped plan for "pulling the suckers on." For the most part the prospectuses and "follow-up" letters were identical.
