Sometimes the young devils incarnate lay in ambush along the Grand'rue or the Basse rue, two streets which are, as it were, the arteries of the town, into which many little side streets open. Crouching, with their heads to the wind, in the angles of the wall and at the corners of the streets, at the hour when all the households were hushed in their first sleep, they called to each other in tones of terror from ambush to ambush along the whole length of the town: "What's the matter?" "What is it?" till the repeated cries woke up the citizens, who appeared in their shirts and cotton night-caps, with lights in their hands, asking questions of one another, holding the strangest colloquies, and exhibiting the queerest faces. A certain poor bookbinder, who was very old, believed in hobgoblins. Like most provincial artisans, he worked in a small basement shop. The Knights, disguised as devils, invaded the place in the middle of the night, put him into his own cutting-press, and left him shrieking to himself like the souls in hell. The poor man roused the neighbors, to whom he related the apparitions of Lucifer; and as they had no means of undeceiving him, he was driven nearly insane. In the middle of a severe winter, the Knights took down the chimney of the collector of taxes, and built it up again in one night apparently as it was before, without making the slightest noise, or leaving the least trace of their work. But they so arranged the inside of the chimney as to send all the smoke into the house. The collector suffered for two months before he found out why his chimney, which had always drawn so well, and of which he had often boasted, played him such tricks; he was then obliged to build a new one. At another time, they put three trusses of hay dusted with brimstone, and a quantity of oiled paper down the chimney of a pious old woman who was a friend of Madame Hochon. In the morning, when she came to light her fire, the poor creature, who was very gentle and kindly, imagined she had started a volcano. The fire-engines came, the whole population rushed to her assistance. Several Knights were among the firemen, and they deluged the old woman's house, till they had frightened her with a flood, as much as they had terrified her with the fire. She was made ill with fear. When they wished to make some one spend the night under arms and in mortal terror, they wrote an anonymous letter telling him that he was about to be robbed; then they stole softly, one by one, round the walls of his house, or under his windows, whistling as if to call each other.
