Stout, grizzled and short winded, I am just as nimble as ever in the pretty exercise of running down an illusion. Yet I must confess, as I passed the abattoirs of La Villette, whence blue-smocked butcher-boys were hauling loads of dirty sheepskins, I could not but compare myself to the honest man mentioned in one of Sardou's comedies: "The good soul escaped out of a novel of Paul de Kock's, lost in the throng on the Boulevard Malesherbes, and asking the way to the woods of Romainville." [Illustration: THE INVADERS OF ROMIAINVILLE.] Romainville! And hereabouts its tufts of chestnuts should be, or were wont to be of old. I am in the grimy quarter of Belleville. Scene of factories, of steam-works and tall bleak mansions as it is to-day, Belleville was once a jolly country village, separated on its hilltop from Paris, which basked at its feet like a city millionaire sprawling before the check apron and leather shoes of a rustic beauty. Inhabited by its little circle of a few thousand souls, it looked around itself on its eminence, seeing the vast diorama of the city on one side, and on the other the Près-Saint-Gervais, and the woods of Romainville waving off to the horizon their diminishing crests of green. A jolly old tavern, the Ile d'Amour, hung out its colored lamps among the trees, and the orchestra sounded, and the feet of gay young lovers, who now are skeletons, beat the floor. The street was a bower of lilacs, and opposite the Ile d'Amour was the village church. Then the workmen of the Paris suburbs were invaders: they besieged the village on Sundays in daring swarms, to be beaten back successfully by the duties of every successive Monday. Now they are fixed there. They are the colorless inhabitants of these many-storied houses. The town's long holiday is over. Where the odorous avenues of lilacs stretched along, affording bouquets for maman and the children and toothpicks for ferocious young warriors from the garrisons, are odious lengths of wall. Everything is changed, and from the gardens the grisettes of Alfred de Musset are with sighing sent. Their haunts are laboratories now, and the Ile d'Amour is a mayor's office.
