without any possibility of error. "We shan't be robbed so much," remarked Bourdoncle, with satisfaction. "This was a very good idea of yours." "And I thought of something else last night," explained Mouret. "Yes, my dear fellow, at supper. I have an idea of giving the clearing-house clerks a little bonus for every error they detect while checking the bills. You understand, eh? Like this we shall be sure that they won't pass any, for rather than do that they'll be inventing mistakes!" He began to laugh, whilst the other looked at him admiringly. This new application of the struggle-for-existence theory delighted Mouret; he had a real genius for administrative functions, and dreamed of so organizing the establishment as to trade upon the selfish instincts of his employees, for the greater satisfaction of his own appetites. He often said that to make people do their best, and even to keep them fairly honest, it was first of all necessary to excite their selfish desires. "Well, let's go downstairs," he resumed. "We must look after this sale. The silk arrived yesterday, I believe, and Bouthemont must be getting it in now." Bourdoncle followed him. The receiving office was in the basement on the side of the Rue Neuve-Saint-Augustin. There, on a level with the pavement, was a kind of glazed cage, into which the vans discharged the goods. They were weighed, and then shot down a rapid slide, whose oak and iron work was polished by the constant chaffing of bales and cases. Everything entered by this yawning trap; it was a continuous swallowing up, a niagara of goods, falling with a roar like that of a torrent. At the approach of big sale times especially, the slide brought down an endless stream of Lyons silks, English woollens, Flemish linens, Alsatian calicoes, and Rouen prints. The vans were sometimes obliged to wait their turn along the street; and as each bale rushed down to the basement there arose a sound as of a stone thrown into deep water. On his way Mouret stopped for a moment before the slide, which was in full activity. Rows of cases were coming down of themselves, falling like rain from some upper stream. Then bales appeared, toppling over in their descent like rolling stones. Mouret looked on, without saying a word. But this wealth of goods rushing in to his establishment at the rate of thousands of francs each minute, made his clear eyes glisten. He had never before had such a clear, definite idea of the struggle he was engaged in. It was this falling mountain of goods which he must cast to the four corners of Paris. He did not open his mouth, however, but continued his inspection.
