The notions of a Pall Mall dandy respecting Southwark or the Tower Hamlets are not more vague than those of the Parisian bourgeois or the Professional French journalist respecting the vast Faubourgs peopled by the working men which encircle this city. From actual observation they know nothing of them. They believe them to be the homes of a dangerous class--communistic and anarchical in its tendencies, the sworn foes alike of law, order, and property. The following are the articles of faith of the journalist:--France is the world. Paris is France. The boulevards, the theatres, some fifty writers on the press, and the bourgeoisie of the fashionable quarters of the city, are Paris. Within this narrow circle he may reason justly, but he never emerges from it, and consequently cannot instruct others about what he does not know himself. Since the fall of the Emperor, the Parisian bourgeois has vaguely felt that he has been surrounded by two hostile armies--the Prussian without the walls, and the working men within. He has placed his trust in Trochu, as twenty years ago he did in Cavaignac. The siege had not lasted a week before he became convinced that the Prussians were afraid of him, because they had not attacked the town; and within the last few days he has acquired the conviction, upon equally excellent grounds, that the working men also tremble before his martial attitude. On Friday last he achieved what he considers a crowning triumph, and he is now under the impression that he has struck terror into the breasts of the advocates of the Commune by marching with his battalion to the Hotel de Ville. "We"--and by "we" he means General Trochu and himself--"we have shown them that we are not to be trifled with," is his boast from morning to night. Now, if instead of reading newspapers which only reflect his own views, and passing his time, whether on the ramparts or in a cafe, surrounded by men who share his prejudices, the worthy bourgeois would be good enough to accompany me to Belleville or La Villette, he would perhaps realise the fact that, as usual, he is making himself comfortable in a fool's paradise. He would have an opportunity to learn that, while the working men have not the remotest intention to pillage his shop, they are equally determined not to allow him and his friends to make Paris the laughing-stock of Europe. With them the "Commune" is but a means to an end. What they want is a Government which will carry out in sober earnest M. Jules Favre's rhetorical figure that "the Parisians will bury themselves beneath the ruins of their town rather than surrender." The lull in the "demonstrations" to urge the Government either to carry out this programme, or to associate with themselves men of energy who are ready to do so, will not last long; and when next Belleville comes to the Hotel de Ville, it will not be unarmed. The bourgeois and the working man worship different gods, and have hardly two ideas in common. The
