There was the Rue Saint-Jacques, with its old book-sellers and seventeenth-century houses, and especially--what dread reminiscences!--the heavy-leaved gate of the Louis-le-Grand Lycée, where Robespierre, Camille Desmoulins, and the future Marshal Brune had studied under the mastership of the good Abbé Berardier. I confess that the Louis-le-Grand of our boyhood was black, and gloomy enough also, with its moss-grown playgrounds, its smoky rooms, its punishment chambers up under the roof, where one was frozen in winter and stifled in summer, its punishment chambers in which tradition relates that Saint-Huruge was confined; quite near to the Saint-Jacques blind alley where Auvergne dealers sold such fine trinkets, and to the little Rue Cujas, noisy with the noise of rowdy students--but which rendered us pensive. There was the Sorbonne, with its paved courtyard, where we used to wait, pale, feverish and anxious, for the posting of the small white notice bearing the names of those candidates for the Baccalaureat that were admitted to the _vivâ voce_; and we were half-dead with fear at the idea of appearing before the terrible Monsieur Bernès, while we blessed the gods to have given us as examiner the witty and indulgent Monsieur Mézières, who, at least for his part, has not grown old. [Illustration: THE INNER COURTYARD OF THE ECOLE POLYTECHNIQUE _Etching by Martial_] Further on, in the rear of Sainte-Barbe, we come to the Rue de la Montagne-Sainte-Geneviève, alive and teeming with its old mansions converted into dispensaries or business premises, its petty trades, its popular dancing-rooms, and, last but not least, its celebrated École Polytechnique, dear to all Parisians, which adds its note of cheerfulness to this somewhat sombre quarter. [Illustration: THE RUE CLOVIS IN 1867 _Drawn by A. Maignan_] Quite near there is the Rue Clovis, where formerly stood the Abbey of Sainte-Geneviève, whose square tower still remains and makes us regret the part that has disappeared. In this Rue Clovis may be seen, crumbling to decay and half-buried under climbing plants--lichens, ivy, sage and moss--a big side of a primitive-looking wall, a fragment of the fortifications of Philippe-Auguste, the belt of stone and lofty strong towers behind which for centuries were heaped houses, palaces, colleges, churches and abbeys, huddling against one another. The church of Saint-Etienne-du-Mont opens its elegant portal a few yards away from the Rue Clovis. Illustrious dead were buried there: Pascal, Racine, Boileau. A crime was also committed in it.
