Baron Haussmann had set pick and spade to work there, and many an ancient tenement and court had been swept away in piercing the Rue des Écoles and the Boulevard St. Michel, then called "Boulevard Sebastopol, Rive Gauche." At that time the Chaumière was dead, the Prado also had disappeared, and the Closerie des Lilas--afterwards known as the Bal Bullier--had lately been renovated, in fact transformed, as Privat d'Anglemont recorded in one of the last sketches he wrote prior to his death in 1859. And with the disappearance or alteration of the old dancing places and _tabagies_, with the demolition of many an ancient den and haunt, the inhabitants of the Quartier and their manners and customs were likewise altering. In fact, there was a great crisis in _la vie de Bohême_. But though it was no longer such as it had been pictured by Murger, such as it had appeared to Théodore de Banville, who, recalling his youth, described it briefly yet forcibly a few years later,[4] it would be a mistake to imagine that it was altogether dead. Alphonse Daudet, who arrived in Paris from Nîmes a few months before Zola entered the Lycée St. Louis, has shown that many of the old habits and customs remained. Again, the writer of these pages, who knew the Quartier Latin well in the last years of the Second Empire, can recall that vestiges of its former life clung to it even till the war of 1870. There were still a few tenth-year students, still a few _rapins_, still a few _grisettes_, of a kind, lingering within its precincts. But the war proved the final _coup de grâce_; and the Quartier of the Third Republic with its _chic_ students, its gambling hells, its _demi-monde_, its _filles de brasserie_, its garish vulgarity, its mock propriety, has resembled the old one in little save its studiousness, for, however much, for centuries past, its young men may have amused themselves, whatever their eccentricities, whatever their excesses, they have also studied, accumulated in that same Quartier a rich store of scholarship and science, which has enabled many of them to confer benefits on mankind.
