Again: Public safety demands this investigation because of the superior opportunities it will afford to reformatory measures. Start not at the supposition of reforming courtesans. There is hope even for them, for they are human beings, though depraved. Their hearts throb with the same sympathies that move the more favored of their sex. Their minds are susceptible to the same emotions as those of other females. Few of them become vile from natural instincts: poor victims of circumstances, many of them would gladly amend if the proper means were used at the proper time. "There is in every human heart Some not entirely barren part, Where flowers of richest scent may blow, And fruit in glorious sunlight grow." This consummation can be achieved only when the pseudo-virtue of the world shall yield to true benevolence, and charity be in deed what it professes in name. If public safety is thus urgent, private interest also has arguments in favor of investigating prostitution. No one need be told that public aid is required to give medical treatment to the unfortunate men and women tainted by this vice; nor need any one be assured that such aid, administered with every regard to economy, requires yearly a large portion of the taxes paid by individuals. It would be sheer folly to assert that any measures which can follow this inquiry will be efficacious in eradicating syphilis, but experience proves that an effective supervision would materially abate its influence, render it curable in a much shorter space of time, and reduce the expenses for each patient in a corresponding ratio. Another large claim upon the public funds arises from the necessity of employing an extensive judicial and police organization to deal with the crime and the criminals generated and fostered in houses of ill fame. Nests of vice as they are now in their darkness and seclusion, it would be impossible to suppose a more fitting nursery for crime, or one whence more criminals would emanate. As with disease, so with crime. It can not be suppressed by placing its retreats under public notice, but it can be watched, and, once brought to the light of day, half its dangers and difficulties become surmountable. Finally, private interest demands this investigation on mere private grounds--the individual and personal expenses caused by diseases contracted by debauchery. There is the money a working man must pay for his cure: this is his share of the loss. There is the unproductive time, and the loss of profits upon his labor: this is his employer's sacrifice. There is the deprivation of comforts and necessaries experienced by his family and dependents: this is their penalty. Society is thus involved in a general loss on account of an act of folly, or passion, or crime (call it which you please), committed in a concealed and secret haunt, and such loss could be saved by the intervention of proper means.
