On the 5th of January (fourth and last night here), his Majesty gave a grand Ball. Had hired, or Colonel Posadowsky instead of him had hired, the Assembly Rooms (REDOUTEN-SAAL), for the purpose: "Invite all the Nobility high and low;"--expense by estimate is a ducat (half-guinea) each; do it well, and his Majesty will pay. About 6 in the evening, his Majesty in person did us the honor to drive over; opened the Ball with Madam the Countess von Schlegenberg (I should guess, a Dowager Lady), in whose house he lodges. I am not aware that his Majesty danced much farther; but he was very condescending, and spoke and smiled up and down;--till, about 10 P.M., an Officer came in with a Letter. Which Letter his Majesty having read, and seemingly asked a question or two in regard to, put silently in his pocket, as if it were a finished thing. Nevertheless, after a few minutes, his Majesty was found to have silently withdrawn; and did not return, not even to supper. Perceiving which, all the Prussian official people gradually withdrew; though the dancing and supping continued not the less, to a late hour. [_Helden-Geschichte,_ i. 557.] "Open the Austrian Mail-bag (FELLEISEN); see a little what they are saying over there!" Such order had evidently been given, this night. In consequence of which, people wrote by Dresden, and not the direct way, in future; wishing to avoid that openable FELLEISEN. Next morning, January 6th, his Majesty had left for Ohlau,--early, I suppose; though there proved to be nothing dangerous ahead there, after all. Chapter V. -- FRIEDRICH PUSHES FORWARD TOWARDS BRIEG AND NEISSE. Ohlau is a pleasant little Town, two marches southeast of Breslau; with the Ohlau River on one side, and the Oder on the other; capable of some defence, were there a garrison. Brieg the important Fortress, still on the Oder, is some fifteen miles beyond Ohlau; after which, bending straight south and quitting Oder, Neisse the still more important may be thirty miles:--from Breslau to Neisse, by this route (which is BOW, not STRING), sixty-five or seventy miles. One of my Topographers yields this Note, if readers care for it:--
