Three weeks after, the minister summoned me to say that he had spoken of me to M. Erizzo, the Venetian ambassador, who had nothing to say against me, but for fear of embroiling himself with the State Inquisitors declined to receive me. Not wanting anything from him--his refusal did me no harm. M. de Bernis then told me that he had given a copy of my history to Madame la Marquise de Pompadour, and he promised to take the first opportunity of presenting me to this all-powerful lady. "You can present yourself, my dear Casanova," added his excellence, "to the Duc de Choiseul, and M. de Boulogne, the comptroller. You will be well received, and with a little wit you ought to be able to make good use of the letter. He himself will give you the cue, and you will see that he who listens obtains. Try to invent some useful plan for the royal exchequer; don't let it be complicated or chimerical, and if you don't write it out at too great length I will give you my opinion on it." I left the minister in a pleased and grateful mood, but extremely puzzled to find a way of increasing the royal revenue. I knew nothing of finance, and after racking my brains all that I could think of was new methods of taxation; but all my plans were either absurd or certain to be unpopular, and I rejected them all on consideration. As soon as I found out that M. de Choiseul was in Paris I called on him. He received me in his dressing-room, where he was writing while his valet did his hair. He stretched his politeness so far as to interrupt himself several times to ask me questions, but as soon as I began to reply his grace began to write again, and I suspect did not hear what I was saying; and though now and again he seemed to be looking at me, it was plain that his eyes and his thoughts were occupied on different objects. In spite of this way of receiving visitors--or me, at all events, M. de Choiseul was a man of wit. When he had finished writing he said in Italian that M. de Bernis had told him of some circumstances of my escape, and he added, "Tell me how you succeeded." "My lord, it would be too long a story; it would take me at least two hours, and your grace seems busy." "Tell me briefly about it." "However much I speak to the point, I shall take two hours." "You can keep the details for another time." "The story is devoid of interest without the details." "Well, well, you can tell me the whole story in brief, without losing much of the interest." "Very good; after that I can say no more. I must tell your lordship, then, that, the State Inquisitors shut me up under the Leads; that after fifteen months and five days of imprisonment I succeeded in piercing the roof; that after many difficulties I reached the chancery by a window, and broke open the door; afterwards I got to St. Mark's Place, whence, taking a gondola which bore me to the mainland, I arrived at Paris, and have had the honour to pay my duty to your lordship." "But.... what are The Leads?"
