Large cities and thinly settled places are the _extremes_ of social life. Here, of course, vice will be found in its worst forms. It is more difficult to say which extreme is worst, among _an equal number of individuals_; but probably the city; for in the country, vice is oftener solitary, and less frequently social; while in the city it is not only _social_ but also _solitary_. A well informed gentleman from New Orleans, of whose own virtue by the way, I have not the _highest_ confidence, expressed, lately the strongest apprehension that the whole race of young men in our cities, of the present generation, will be ruined. Others have assured me that in the more northern cities, the prospect is little, if any, more favorable. It is to be regretted that legislators have not found out the means of abolishing those haunts in cities which might be appropriately termed schools of licentiousness, and thus diminishing an aggregate of temptation already sufficiently large. But the vices, like their votaries, go in companies. Until, therefore, the various haunts of intemperance in eating and drinking, and of gambling and stage-playing, can be broken up, it may be considered vain to hope for the disappearance of those sties of pollution which are their almost inevitable results. We might as well think of drying up the channel of a mighty river, while the fountains which feed it continue to flow as usual. There is now in Pennsylvania,--it seems unnecessary to name the place--a man thirty-five years old, with all the infirmities of 'three score and ten.' Yet his premature old age, his bending and tottering form, wrinkled face, and hoary head, might be traced to solitary and social _licentiousness_. This man is not alone. There are thousands in every city who are going the same road; some with slow and cautious steps, others with a fearful rapidity. Thousands of youth on whom high expectations have been placed, are already on the highway that will probably lead down to disease and premature death.
