Some time after, my thoughts were occupied with a business speculation which all my calculations assured me would be extremely profitable. The plan was to produce on silks, by means of printing, the exquisite designs which are produced at Lyons by the tedious process of weaving, and thus to give customers excellent value at much lower prices. I had the requisite knowledge of chemistry, and enough capital to make the thing a success. I obtained the assistance of a man with the necessary technical skill and knowledge, intending to make him my manager. I told my plan to the Prince de Conti, who encouraged me to persevere, promising me his patronage, and all the privileges I could wish for. That decided me to begin. I rented a very large house near the Temple for a thousand crowns per annum. The house contained a spacious hall, in which I meant to put my workmen; another hall which was to be the shop; numerous rooms for my workpeople to live in; and a nice room for myself in case I cared to live on the premises. I made the scheme into a company with thirty shares, of which I gave five to my designer, keeping the remaining twenty-five to distribute to those who were inclined to join the company. I gave one to a doctor who, on giving surety, became the storekeeper, and came to live in the house with his whole family; and I engaged four servants, a waiting-maid, and a porter. I had to give another share to an accountant, who furnished me with two clerks, who also took up their abode in the house. The carpenters, blacksmiths, and painters worked hard from morning to night, and in less than three weeks the place was ready. I told the manager to engage twenty girls to paint, who were to be paid every Saturday. I stocked the warehouse with three hundred pieces of sarcenet and camlet of different shades and colours to receive the designs, and I paid for everything in ready money. I had made an approximate calculation with my manager that I should have to spend three hundred thousand francs, and that would not break me. If the worst happened I could fall back on my shares, which produced a good income, but I hoped I should not be compelled to do so, as I wanted to have an income of two hundred thousand francs a year. All the while I did not conceal from myself that the speculation might be my ruin, if custom did not come in, but on looking at my beautiful materials these fears were dispelled, especially as I heard everybody saying that I sold them much too cheap. To set up the business I spent in the course of a month about sixty thousand francs, and my weekly expenses amounted to twelve hundred francs. As for Madame d'Urfe she laughed every time she saw me, for she was quite certain that this business was only meant to put the curious off the scent and to preserve my incognito: so persuaded was she of my omnipotence.
