Pepy's Diary. 23 Feb 1660. Thursday, my birthday, now twenty-seven years. A pretty fair morning, I rose and after writing a while in my study I went forth. To my office, where I told Mr. Hawly of my thoughts to go out of town to-morrow. Hither Mr. Fuller comes to me and my Uncle Thomas too, thence I took them to drink, and so put off my uncle. So with Mr. Fuller (age 52) home to my house, where he dined with me, and he told my wife and me a great many stories of his adversities, since these troubles, in being forced to travel in the Catholic countries, &c. He shewed me his bills, but I had not money to pay him. We parted, and I to Whitehall, where I was to see my horse which Mr. Garthwayt lends me to-morrow. So home, where Mr. Pierce comes to me about appointing time and place where and when to meet tomorrow. !So to Westminster Hall [Map], where, after the House rose, I met with Mr. Crew (age 62), who told me that my Lord was chosen by 73 voices, to be one of the Council of State. Mr. Pierpoint (age 52) had the most, 101, and himself the next, too. He brought me in the coach home. He and Mr. Anslow (age 45) being in it. I back to the Hall, and at Mrs. Michell's shop staid talking a great while with her and my Chaplain, Mr. Mumford, and drank a pot or two of ale on a wager that Mr. Prin (age 60) is not of the Council. Home and wrote to my Lord the news of the choice of the Council by the post, and so to bed.

Pepy's Diary. 13 Jun 1667. In the evening comes Mr. Pelling, and several others, to the office, and tell me that never were people so dejected as they are in the City all over at this day; and do talk most loudly, even treason; as, that we are bought and sold-that we are betrayed by the Papists, and others, about the King (age 37); cry out that the office of the Ordnance hath been so backward as no powder to have been at Chatham, Kent [Map] nor Upnor Castle, Kent [Map] till such a time, and the carriages all broken; that Legg is a Papist; that Upnor [Map], the old good castle built by Queen Elizabeth, should be lately slighted; that the ships at Chatham, Kent [Map] should not be carried up higher. They look upon us as lost, and remove their families and rich goods in the City; and do think verily that the French, being come down with his army to Dunkirke, it is to invade us, and that we shall be invaded. Mr. Clerke, the solicitor, comes to me about business, and tells me that he hears that the King (age 37) hath chosen Mr. Pierpont (age 59) and Vaughan (age 63) of the West, Privy-councillors; that my Chancellor (age 58) was affronted in the Hall this day, by people telling him of his Dunkirke house; and that there are regiments ordered to be got together, whereof to be commanders my Lord Fairfax (age 55), Ingoldsby (age 49), Bethell, Norton, and Birch (age 51), and other Presbyterians; and that Dr. Bates will have liberty to preach. Now, whether this be true or not, I know not; but do think that nothing but this will unite us together.

Pepy's Diary. 12 Dec 1667. Thence walked to my bookseller's, and there he did give me a list of the twenty who were nominated for the Commission in Parliament for the Accounts: and it is strange that of the twenty the Parliament could not think fit to choose their nine, but were fain to add three that were not in the list of the twenty, they being many of them factious people and ringleaders in the late troubles; so that Sir John Talbott did fly out and was very hot in the business of Wildman's being named, and took notice how he was entertained in the bosom of the Duke of Buckingham (age 39), a Privy-counsellor; and that it was fit to be observed by the House, and punished. The men that I know of the nine I like very well; that is, Mr. Pierrepont (age 59), Lord Brereton (age 36), and Sir William Turner (age 52); and I do think the rest are so, too; but such as will not be able to do this business as it ought to be, to do any good with. Here I did also see their votes against my Lord Chiefe Justice Keeling (age 60), that his proceedings were illegal, and that he was a contemner of Magna Charta (the great preserver of our lives, freedoms, and properties) and an introduction to arbitrary government; which is very high language, and of the same sound with that in the year 1640. I home, and there wrote my letters, and so to supper and to bed. This day my Chancellor's (age 58) letter was burned at the 'Change [Map].'
