At that epoch there were no gas-jets in the streets of Paris. At nightfall lanterns placed at regular distances were lighted; they were ascended and descended by means of a rope, which traversed the street from side to side, and was adjusted in a groove of the post. The pulley over which this rope ran was fastened underneath the lantern in a little iron box, the key to which was kept by the lamplighter, and the rope itself was protected by a metal case.

Jean Valjean, with the energy of a supreme struggle, crossed the street at one bound, entered the blind alley, broke the latch of the little box with the point of his knife, and an instant later he was beside Cosette once more. He had a rope. These gloomy inventors of expedients work rapidly when they are fighting against fatality.

We have already explained that the lanterns had not been lighted that night. The lantern in the Cul-de-Sac Genrot was thus naturally extinct, like the rest; and one could pass directly under it without even noticing that it was no longer in its place.
