As Friedrich did not get into war, and Catharine did, with the Turks and certain loose Polacks, the burden of fulfilment happened to fall wholly on Friedrich; and he was extremely punctual in performance,--eager now, and all his life after, to keep well with such a Country under such a Czarina. Which proved to be the whole rule of his policy on that Russian side. "Good that Country cannot bring me by any quarrel with it; evil it can, to a frightful extent, in case of my quarrelling with others! Be wary, be punctual, magnanimously polite, with that grandiose Czarina and her huge territories and notions:" this was Friedrich's constant rule in public and in private. Nor is it thought his CORRESPONDENCE WITH THE EMPRESS CATHARINE, when future generations see it in print, will disclose the least ground of offence to that high-flying Female Potentate of the North. Nor will it ever be known what the silently observant Friedrich thought of her, except indeed what we already know, or as good as know, That he, if anybody did, saw her clearly enough for what she was; and found good to repress into absolute zero whatever had no bearing upon business, and might by possibility give offence in that quarter. For we are an old King, and have learned by bitter experiences! No more nicknames, biting verses, or words which a bird of the air could carry; though this poor Lady too has her liabilities, were not we old and prudent;--and is entirely as weak on certain points (deducting the devotions and the brandy-and-water) as some others were! The Treaty was renewed when necessary; and continued valid and vital in every particular, so long as Friedrich ruled. By the end of the first eight years, by strictly following this passive rule, Friedrich, in counterbalance of his losses, unexpectedly found himself invested with a very singular bit of gain,--"unjust gain!" cried all men, making it of the nature of gain and loss to him,--which is still practically his, and which has made, and makes to this day, an immense noise in the world. Everybody knows we mean West-Preussen; Partition of Poland; bloodiest picture in the Book of Time, Sarmatia's fall unwept without a crime;--and that we have come upon a very intricate part of our poor History.
