The part of Paris where Jean Valjean now was, situated between the Faubourg St. Antoine and la Rapée, was one of those which have been utterly transformed by those recent works which some call disfigurements, others beautifying. The fields, the timber-yards, and old buildings have been removed, and there are now brand-new wide streets, arenas, circuses, hippodromes, railway stations, and a prison, Mazas,--progress as we see with its corrective. Half a century back, in that popular language all made up of traditions which insists on calling the Institute "les Quatre Nations," and the Opéra Comique "Feydeau," the precise spot where Jean Valjean now stood was called "le Petit Picpus." The Porte St. Jacques, the Porte Paris, the Barrière des Sergents, the Porcherons, the Galiote, the Celestins, the Capucins, the Mail, the Bourbe, the tree of Cracow, Little Poland, and Little Picpus, are names of old Paris swimming on the surface of the new. The memory of the people floats on the flotsam of the past. Little Picpus, which by the way scarce existed, and was never more than the outline of a quarter, had almost the monastic look of a Spanish town. The streets were scarce paved, and hardly any houses lined them; excepting two or three streets, to which we are about to refer, all was wall and solitude. There was not a shop or a vehicle, scarce a candle lighted in the windows, and every light was put out by ten o'clock. The quarter consisted of gardens, convents, timber-yards, and kitchen-grounds, and there were a few low houses with walls as lofty as themselves. Such was the quarter in the last century; the Revolution fiercely assailed it, and the Republican board of works demolished and made gaps in it: rubbish was allowed to be shot there. Thirty years ago this quarter was disappearing under the erasure of new buildings, and now it is entirely obliterated. Little Picpus, of which no modern map retains a trace, is very clearly indicated in the plan of 1727, published at Paris by Denis Thierry, Rue St. Jacques, opposite the Rue du Plâtre; and at Lyons by Jean Girin, Rue Mercière. Little Picpus had what we have just called a Y of streets formed by the Rue du Chemin Vert St. Antoine dividing into two branches, the left-hand one taking the name of the Petite Rue Picpus, and the right-hand that of Rue Polonceau. The two branches of the Y were joined at their summit by a sort of cross-bar called Rue Droit-mur. Any one who, coming from the Seine, reached the end of Rue Polonceau, had on his left Rue Droit-mur, turning sharply at a right angle, in front of him the wall of that street, and on his right a truncated prolongation of the Rue Droit-mur called the Cul-de-sac Genrot.
