A tendency to sap the foundation upon which rest the pillars of morality, and to poison the minds of youth, seems to be a prevailing vice. High literary attainments, great mental powers, have been brought into the arena to battle for crime, lasciviousness, and vice. In all ages the vile corruption of man’s nature, aided by genius and talent, has been manifested in the production of things evil. The rapid and, we may say, alarming increase of crime, the callousness manifested at the recital of human suffering, the want, or, rather, the absence, of a correct moral standard in every thing appertaining to social life, the sneering at the tenets of our holy religion, the assumption as it were of omniscient powers on the part of sinful men, have led to a state of things which will require stronger measures than that of mere reasoning to remedy. Our streets of a night are flooded with the daughters of vice; temples are dedicated to licentiousness, sanctioned by the authorities, who grant them “license” as it were to corrupt youth and demoralize the masses. Intemperance and pauperism are the results of the “law’s license” to common crime. Thus the dark shadow of vice extends its fatal power over that portion of the human family from whose domestic circle the voice of prayer never ascends. There instead is heard the sound of rattling glasses: loud oaths, the bacchanalian song, there throw around the circle of which they form the nucleus an atmosphere to poison and destroy. Much of all this can be traced to the estimate men place upon the modern mode of education. If genius invents something that places vice in a brilliant light, in and through which all that is startling in picture-view or description presents new features to the novice in licentiousness, it becomes at once an institution from whence flows a stream that poisons a city. In an instant these productions take miniature shapes: art combines with the genius of the originators, and, lo! they go forth through the post, spreading ruin and desolation everywhere. It is that very facility which the post affords that gives power and influence to these fiends; and, alas! how many, dazzled by the “refinement of vice,”—refined by the touch of art,—fall into the snare by the very excitement they produce! Many of these photographs of the more vile character reach “young ladies’ seminaries.” Many books of a similar character find their way hither, and thus corruption works its way to the ruin of their inmates. We would have—what under no other circumstance would we suggest to the department—_an espionage over all suspicious postal matter_. _ESPIONAGE OVER THE POST-OFFICE IN FRANCE._
