With a wave of his hand he pointed to the city, slumbering in the moonlight as beneath a sheet of silver, and then set off again with his brother, down the slopes, towards the black and deserted streets. They did not meet a living soul until they reached the outer boulevard. Here, however, no matter what the hour may be, life continues with scarcely a pause. No sooner are the wine shops, music and dancing halls closed, than vice and want, cast into the street, there resume their nocturnal existence. Thus the brothers came upon all the homeless ones: low prostitutes seeking a pallet, vagabonds stretched on the benches under the trees, rogues who prowled hither and thither on the lookout for a good stroke. Encouraged by their accomplice--night, all the mire and woe of Paris had returned to the surface. The empty roadway now belonged to the breadless, homeless starvelings, those for whom there was no place in the sunlight, the vague, swarming, despairing herd which is only espied at night-time. Ah! what spectres of destitution, what apparitions of grief and fright there were! What a sob of agony passed by in Paris that morning, when as soon as the dawn should rise, a man--a pauper, a sufferer like the others--was to be guillotined! As Guillaume and Pierre were about to descend the Rue des Martyrs, the former perceived an old man lying on a bench with his bare feet protruding from his gaping, filthy shoes. Guillaume pointed to him in silence. Then, a few steps farther on, Pierre in his turn pointed to a ragged girl, crouching, asleep with open month, in the corner of a doorway. There was no need for the brothers to express in words all the compassion and anger which stirred their hearts. At long intervals policemen, walking slowly two by two, shook the poor wretches and compelled them to rise and walk on and on. Occasionally, if they found them suspicious or refractory, they marched them off to the police-station. And then rancour and the contagion of imprisonment often transformed a mere vagabond into a thief or a murderer.
