Paris is the centre, the banlieue is the circumference,--that is, the whole earth, for these children. They never venture beyond it, and can no more leave the Parisian atmosphere than fish can live out of water. With them there is nothing beyond two leagues from the barrière; Ivry, Gentilly, Arcueil, Belleville, Aubervilliers, Ménilmontant, Choisy le Roi, Bellancourt, Meudon, Issy, Vauvres, Sèvres, Puteaux, Neuilly, Gennevilliers, Colombes, Romainville, Chalon, Asnières, Bougival, Nanterre, Enghien, Noisy-le-sec, Nogent, Gournay, Drancy, and Gonesse, --at these places their universe ends. CHAPTER VI. A BIT OF HISTORY. At the epoch almost contemporary with the action of this book there was not, as at the present day, a policeman at every street corner (a blessing which we have no time to discuss), and wandering children abounded in Paris. Statistics give us an average of two hundred and sixty shelterless children picked up annually by the police of that day in unenclosed fields, in houses building, and under the arches of bridges. One of these nests, which became famous, produced "the swallows of the Rue d'Arcole." This, by the way, is the most disastrous of social symptoms, for all the crimes of the man begin with the vagabondage of the lad. We must except Paris, however, and in a relative degree, and in spite of the statistics we have just quoted, the exception is fair. While in any other great city a vagabond child is a ruined man, while nearly everywhere the boy left to himself is to some extent devoted and left to a species of fatal immersion in public vice, which destroys honor and conscience within him, the gamin of Paris, though externally so injured, is internally almost intact. It is a magnificent thing to be able to say, and one revealed in the splendid probity of our popular revolutions, that a certain incorruptibility emanates from the idea which is in the atmosphere of Paris, as from the salt which is in the ocean water. Breathing Paris preserves the soul. But what we have just stated does not in any way decrease the heart-contraction which we feel every time we meet one of these lads, around whom we fancy that we can see the threads of the broken family fluttering. In our present civilization, which is still so incomplete, it is not a very abnormal fact that families thus broken up should not know what becomes of their children, and allow their own flesh and blood to fall upon the highway. Hence come these obscure destinies; and this sad thing has become proverbial, and is known as "being cast on the pavement of Paris."
