Baron Hartmann, who had followed Mouret's gesture, was looking at the ladies through the doorway which was wide open. And he continued listening to them with one ear, whilst the young man, inflamed by his desire to convince him, went yet deeper into the question, explaining the mechanism of the new style of drapery business. This branch of commerce was now based on a rapid and continual turning over of capital, which it was necessary to convert into goods as often as possible in the same year. For instance, that year his capital, which only amounted to five hundred thousand francs, had been turned over four times, and had thus produced business to the amount of two millions. But this was a mere trifle, which could be increased tenfold, for later on, in certain departments, he certainly hoped to turn the capital over fifteen or twenty times in the course of the twelvemonth. "You understand, baron, the whole system lies in that. It is very simple, but it had to be found out. We don't need an enormous working capital; the sole effort we have to make is to get rid of the stock we buy as quickly as possible so as to replace it by other stock which each time will make our capital return interest. In this way we can content ourselves with a very small profit; as our general expenses amount to as much as sixteen per cent., and as we seldom make more than twenty per cent. on our goods, there is only a net profit of four per cent. at the utmost; only this will finish by representing millions when we can operate on large quantities of goods incessantly renewed. You follow me, don't you? nothing can be clearer." The baron again shook his head doubtfully. He who had entertained the boldest schemes and whose daring at the time of the introduction of gas-lighting was still spoken of, remained in the present instance uneasy and obstinate. "I quite understand," said he; "you sell cheap in order to sell a quantity, and you sell a quantity in order to sell cheap. But you must sell, and I repeat my former question: Whom will you sell to? How do you hope to keep up such a colossal sale?" A loud exclamation, coming from the drawing-room, interrupted Mouret just as he began to reply. It was Madame Guibal declaring that she would have preferred the flounces of old Alençon simply round the upper skirt of the dress. "But, my dear," said Madame de Boves, "the upper skirt was covered with it as well. I never saw anything richer." "Ah, that's a good idea," resumed Madame Desforges, "I've got several yards of Alençon somewhere; I must look them up for a trimming." Then the voices fell again, sinking into a murmur. Prices were quoted, a feverish desire to buy and bargain stirred all the ladies; they were purchasing lace by the mile. "Why?" declared Mouret, when he could at last speak, "one can sell what one likes when one knows how to sell! Therein lies our triumph."
