Not much real money: except, indeed, the money were offered you gratis, from other parties interested?
Sir Jonas kindly informs us, by insinuation, that this was, to a good degree, Friedrich's case in the now Carrousel: "a thing got up by the private efforts of different great Lords and Princes of the blood;" each party tailoring, harnessing and furbishing himself and followers; Friedrich contributing little but the arena and general outfit.

I know not whether even the 40,000 lamps (for it took place by night) were of his purchase, though that is likely; and know only that the Suppers and interior Palace Entertainments would be his.

"Did not cost the King much money," says Sir Jonas; which is satisfactory to know.

For of the Carrousel kind, or of the Royal-Mummery kind in general, there has been, for graceful arrangement, for magnificence regardless of expense,--inviting your amiable Lord Malton, and the idlers of all Countries, and awakening the rapture of Gazetteers,--nothing like it since Louis the Grand's time.
Nothing,--except perhaps that Camp of Muhlberg or Radowitz, where we once were.

Done, this one, not at the King's expense alone, but at other people's chiefly: that is an unexpected feature, welcome if true; and, except for Sir Jonas, would not have helped to explain the puzzle for us, as it did in the then Berlin circles.
