Several months passed away. Denise came in nearly every evening to cheer up Geneviève a bit, but the house became more melancholy than ever. The works opposite were a continual torment, which intensified their bad luck. Even when they had an hour of hope--some unexpected joy--the falling of a tumbrel-load of bricks, the sound of the saw of a stonecutter, or the simple call of a mason, sufficed at once to mar their pleasure. In fact, the whole neighbourhood felt the shock. From the boarded enclosure, running along and blocking up the three streets, there issued a movement of feverish activity. Although the architect used the existing buildings, he altered them in various ways to adapt them to their new uses; and right in the centre at the opening caused by the court-yards, he was building a central gallery as big as a church, which was to terminate with a grand entrance in the Rue Neuve-Saint-Augustin right in the middle of the frontage. They had, at first, experienced great difficulty in laying the foundations, for they had come on to some sewer deposits and loose earth, full of human bones. Besides that, the boring of the well had made the neighbours very anxious--a well three hundred feet deep, destined to give two hundred gallons a minute. They had now got the walls up to the first storey; the entire block was surrounded by scaffolding, regular towers of timber work. There was an incessant noise from the grinding of the windlasses hoisting up the stone, the abrupt discharge of iron bars, the clamour of this army of workmen, accompanied by the noise of picks and hammers. But above all, what deafened the people was the sound of the machinery. Everything went by steam, screeching whistles rent the air; whilst, at the slightest gust of wind, clouds of plaster flew about and covered the neighbouring roofs like a fall of snow. The Baudus in despair looked on at this implacable dust penetrating everywhere--getting through the closest woodwork, soiling the goods in their shop, even gliding into their beds; and the idea that they must continue to breathe it--that it would finish by killing them--empoisoned their existence.
