"On the third day [yesterday evening, in fact], I went, by appointment, to the New Palace, to wait upon the King of Prussia. There was some delay: his Majesty had gone, in the interim, to a private Concert, which he was giving to the Princesses [Duchess of Brunswick and other high guests [Rodenbeck (IN DIE) iii. 98.]]; but the moment he was told I was there, he came out from his company, and gave me a most flattering gracious audience of more than half an hour; talking on a great variety of things, with an ease and freedom the very reverse of what I had been made to expect.... I asked, and received permission, to visit the Silesian Camps next month, his Majesty most graciously telling me the particular days they would begin and end [27th August-3d September, Schmelwitz near Breslau, are time and place [Ib. iii. 101.]]. This considerably deranges my Austrian movements, and will hurry my return out of those parts: but who could resist such a temptation!--I saw the Foot-Guards exercise, especially the splendid 'First Battalion;' I could have conceived nothing so perfect and so exact as all I saw:--so well dressed, such men, and so punctual in all they did. "The New Palace at Potsdam is extremely noble. Not so perfect, perhaps, in point of taste, but better than I had been led to expect. The King dislikes living there; never does, except when there is high Company about him; for seven or eight months in the year, he prefers Little Sans-Souci, and freedom among his intimates and some of his Generals.... His Music still takes up a great share of the King's time. On a table in his Cabinet there, I saw, I believe, twenty boxes with a German flute in each; in his Bed-chamber, twice as many boxes of Spanish snuff; and, alike in Cabinet and in Bed-chamber, three arm-chairs in a row for three favorite dogs, each with a little stool by way of step, that the getting up might be easy.... "The Town of Potsdam is a most extraordinary and, in its appearance, beautiful Town; all the streets perfectly straight, all at right angles to each other; and all the houses built with handsome, generally elegant fronts.... He builds for everybody who has a bad or a small house, even the lowest mechanic. He has done the same at Berlin." Altogether, his Majesty's building operations are astonishing. And "from whence does this money come, after a long expensive War? It is all fairyland and enchantment,"--MAGNUM VECTIGAL PARSIMONIA, in fact!... "At Berlin here, I saw the Porcelain Manufacture to-day, which is greatly improved. I leave presently. Adieu, dear Brother; excuse my endless Letter [since you cannot squeeze the water out of it, as some will!]--Yours most sincerely, "HENRY SEYMOUR CONWAY."
