To such a length have these communist and socialist projects proceeded in Paris, that a great effort of all the holders of property was deemed indispensable to arrest them. The effort was made on Monday, 17th April; but it is hard to say whether the dreaded evils or the boasted demonstration were most perilous, or most descriptive of the present social condition of the French capital. Was it by argument in the public journals, or by influencing the electors for the approaching Assembly, or even by discussion at the Clubs, as in the days of the Jacobins and the Cordeliers, that the thing was done? Quite the reverse: it was effected by a demonstration of _physical strength_. They took a leaf out of the book of the Chartists--they copied the processions of the Janissaries in the Atmeidan of Constantinople. The National Guard, _two hundred and twenty thousand strong_, mustered on the streets of Paris: they shouted out, "A bas les Communistes!"--"A bas Blanqui!"--"Vive le Gouvernement Provisoire!" and the Parisians flattered themselves the thing was done. Is not the remedy worse than the disease? What were fifteen thousand unarmed workmen spouting socialist speeches in the Champs de Mars to 200,000 armed National Guards, dictating their commands alike to the Provisional Government and the National Assembly! Was ever a capital handed over to such a lusty band of metropolitan janissaries? What chance is there of freedom of deliberation in the future Assembly in presence of such formidable spectators in the galleries? Already M. Ledru Rollin is calculating on their ascendancy. Like all persons engaged in a successful insurrection--in other words, who have been guilty of treason--he is haunted by a continual, and in the circumstances ridiculous, dread of a counter-revolution; and in his circular of 15th April, he openly avows the principle that Paris is the soul of France; that it is the advanced guard of Freedom, not for itself alone, but the whole earth; and that the departments must not think of gainsaying the will of their sovereign leaders, or making the cause retrograde, in which all nations are finally to be blessed. The account of this extraordinary demonstration, given in the Paris correspondence of the _Times_ of 19th April, is so characteristic and graphic, that we cannot forbear the satisfaction of laying it before our readers. It recalls the preludes to the worst days of the first Revolution.
