Sir Robert Murray Keith--that is, the younger Excellency Keith, now Minister at Dresden, whom we have sometimes heard of--accompanies Conway on this Tour, or flies alongside of him, with frequent intersections at the principal points; and there is printed record by Sir Robert, but still less interesting than this of Conway, and perfectly conformable to it:--so that, except for some words about the Lord Marischal, which shall be given, Keith must remain silent, while the diffuse Conway strives to become intelligible. Indeed, neither Conway nor Keith tell us the least thing that is not abundantly, and even wearisomely known from German sources; but to readers here, a pair of English eyes looking on the matter (put straight in places by the help there is), may give it a certain freshness of meaning. Here are Conway's Two Letters, with the nine parts of water charitably squeezed out of them, by a skilful friend of mine and his. CONWAY TO HIS BROTHER, MARQUIS OF HERTFORD (in London). "BERLIN, July 17th, 1774. "DEAR BROTHER,--In the hurry I live in--... Leaving Brunswick, where, in absence of most of the Court, who are visiting at Potsdam, my old Commander," Duke Ferdinand, now estranged from Potsdam, [Had a kind of quarrel with Friedrich in 1766 (rough treatment by Adjutant von Anhalt, not tolerable to a Captain now become so eminent), and quietly withdrew,--still on speaking terms with the King, but never his Officer more.] and living here among works of Art, and speculations on Free Masonry, "was very kind to me, I went to Celle, in Hanover, to pay my respects to the Queen of Denmark [unfortunate divorced Matilda, saved by my friend Keith,--innocent, I will hope!]... She is grown extremely fat.... At Magdeburg, the Prussian Frontier on this side, one is not allowed, without a permit, even to walk on the ramparts,--such the strictness of Prussian rule.... Driving through Potsdam, on my way to Berlin, I was stopped by a servant of the good old Lord Marischal, who had spied me as I passed under his window. He came out in his nightgown, and insisted upon our staying to dine with him--[worthy old man; a word of him, were this Letter done]. We ended, on consultation about times and movements of the King, by staying three days at Potsdam, mostly with this excellent old Lord.
