In an instant the wall was attacked by the collection of arms the girls had brought with them. Tongs, pokers, shovels were all brought into play, but luckily without making any impression on the stones, which otherwise might have come rattling about their heads. Besides, the demons dared not make too much noise, for they were afraid of being heard, as they did not know exactly in which part of the convent they might happen to be.
