Lucien went down to L'Houmeau along the broad Promenade de Beaulieu, the Rue du Minage, and Saint-Peter's Gate. It was the longest way round, so you may be sure that Mme. de Bargeton's house lay on the way. So delicious it was to pass under her windows, though she knew nothing of his presence, that for the past two months he had gone round daily by the Palet Gate into L'Houmeau. Under the trees of Beaulieu he saw how far the suburb lay from the city. The custom of the country, moreover, had raised other barriers harder to surmount than the mere physical difficulty of the steep flights of steps which Lucien was descending. Youth and ambition had thrown the flying-bridge of glory across the gulf between the city and the suburb, yet Lucien was as uneasy in his mind over his lady's answer as any king's favorite who has tried to climb yet higher, and fears that being over-bold he is like to fall. This must seem a dark saying to those who have never studied the manners and customs of cities divided into the upper and lower town; wherefore it is necessary to enter here upon some topographical details, and this so much the more if the reader is to comprehend the position of one of the principal characters in the story--Mme. de Bargeton. The old city of Angouleme is perched aloft on a crag like a sugar-loaf, overlooking the plain where the Charente winds away through the meadows. The crag is an outlying spur on the Perigord side of a long, low ridge of hill, which terminates abruptly just above the road from Paris to Bordeaux, so that the Rock of Angouleme is a sort of promontory marking out the line of three picturesque valleys. The ramparts and great gateways and ruined fortress on the summit of the crag still remain to bear witness to the importance of this stronghold during the Religious Wars, when Angouleme was a military position coveted alike of Catholics and Calvinists, but its old-world strength is a source of weakness in modern days; Angouleme could not spread down to the Charente, and shut in between its ramparts and the steep sides of the crag, the old town is condemned to stagnation of the most fatal kind.
