At night, Mr. Conway and I going home with Lord Hertford to supper, the latter found a most pathetic letter from the King, which said the Duke of Grafton had just been with him, and had peremptorily declared he would not go on without Mr. Conway; and therefore his Majesty called upon Mr. Conway, in the most earnest manner, not to leave him exposed to Lord Rockingham, who had insulted him so much. The Duke of Grafton, the latter said too, had promised the King to desire Mr. Walpole would use all his interest with Mr. Conway; to whom his Majesty engaged to give the Blues on Lord Ligonier’s death, and any civil place, if he did not like that of Secretary of State. Mr. Conway cried out at once, it was impossible. I immediately saw that if I persuaded him _then_ to stay, he would dispute, and thence would confirm himself in his resolution. I determined, therefore, to let the first burst of his feeling pass over without contradiction, that I might work on him another way. I walked about the room with as melancholy an air as I could put on, only dropping now and then, that it was the most serious crisis I ever knew. At supper I spoke not a word. When the servants were retired, his brother, Lady Hertford, and his own wife, Lady Ailesbury, attacked him in the most eager manner, pressing him to comply with the King. He resisted as firmly; I jogged Lord Hertford privately, who understood me, and said no more: but the two ladies were out of patience, thinking me on Mr. Conway’s side. Still I would not speak, but seemed to be lost in thought, though I attended to every word he said, to learn where his principal objection lay, and soon found it was to Lord Chatham. When we rose up to go away, the ladies pressed me to give my opinion, which I had expected, and intended to bring them to do. I then spoke with tears in my eyes; said I was sensible of the honour the King had done me; but, for the King nor anybody, would I give Mr. Conway any advice in so important a moment, till I had considered the question most cooly and thoroughly. He was much pleased, and said that was very fair. I then knew I should do what I would; Lord Hertford proposed that he and his brother should go early the next morning to the Duke of Grafton, but I shifted that off, and winked to Lord Hertford, who then said, he would go first, and Mr. Conway should come to me in the morning to talk the matter over. The moment I got home, I wrote back to Lord Hertford to explain my meaning, and desired he would not come to me till an hour after the time appointed for meeting his brother at my house.
