Let us make an exception in favor of Paris, nevertheless. In a relative measure, and in spite of the souvenir which we have just recalled, the exception is just. While in any other great city the vagabond child is a lost man, while nearly everywhere the child left to itself is, in some sort, sacrificed and abandoned to a kind of fatal immersion in the public vices which devour in him honesty and conscience, the street boy of Paris, we insist on this point, however defaced and injured on the surface, is almost intact on the interior. It is a magnificent thing to put on record, and one which shines forth in the splendid probity of our popular revolutions, that a certain incorruptibility results from the idea which exists in the air of Paris, as salt exists in the water of the ocean. To breathe Paris preserves the soul.
