After a square dance, in which I had as partner Mdlle. de Manteufel, the prettiest of the duchess’s maids of honour, her highness told me that supper was ready. I came up to her and offered my arm, and presently found myself seated beside her at a table laid for twelve where I was the only gentleman. However, the reader need not envy me; the ladies were all elderly dowagers, who had long lost the power of turning men’s heads. The duchess took the greatest care of my comforts, and at the end of the repast gave me with her own hands a glass of liqueur, which I took for Tokay and praised accordingly, but it turned out to be only old English ale. I took her back to the ball when we rose from table. The young chamberlain who had invited me told me the names of all the ladies present, but I had no time to pay my court to any of them. The next day I dined with M. de Kaiserling, and handed Lambert over to a Jew to be clothed properly. The day after I dined with the duke with a party consisting only of men. The old prince made me do most of the talking, and towards the end of the dinner the conversation fell upon the resources of the country which was rich in minerals and semi-minerals. I took it into my head to say that these resources ought to be developed, and that they would become precious if that were done. To justify this remark I had to speak upon the matter as if I had made it my principal study. An old chamberlain, who had the control of the mines, after allowing me to exhaust my enthusiasm, began to discuss the question himself, made divers objections, but seemed to approve of many of my remarks. If I had reflected when I began to speak in this manner that I should have to act up to my words, I should certainly have said much less; but as it was, the duke fancied that I knew much more than I cared to say. The result was that, when the company had risen from the table, he asked me if I could spare him a fortnight on my way to St. Petersburg. I said I should be glad to oblige him, and he took me to his closet and said that the chamberlain who had spoken to me would conduct me over all the mines and manufactories in his duchies, and that he would be much obliged if I would write down any observations that struck me. I agreed to his proposal, and said I would start the next day. The duke was delighted with my compliance, and gave the chamberlain the necessary orders, and it was agreed that he should call for me at day-break with a carriage and six. When I got home I made my preparations, and told Lambert to be ready to accompany me with his case of instruments. I then informed him of the object of the journey, and he promised to assist me to the best of his ability, though he knew nothing about mines, and still less of the science of administration.
