Not till Henri's return (FEBRUARY 18th, 1771) could he entirely believe that the Czarina was serious;--and then, sure enough, he did, with his whole heart, go into it: the EUREKA out of all these difficulties, which had so long seemed insuperable.

Prince Henri "had an Interview with the Austrian Minister next day" (February 19th), who immediately communicated with his Kaunitz,--and got discouraging response from Kaunitz; discouraging, or almost negatory; which did not discourage Friedrich.

"A way out," thinks Friedrich: "the one way to save my Prussia and the world from incalculable conflagration." And entered on it without loss of a moment.

And labored at it with such continual industry, rapidity and faculty for guiding and pushing, as all readers have known in him, on dangerous emergencies: at no moment lifting his hand from it till it was complete.
His difficulties were enormous: what a team to drive; and on such a road, untrodden before by hoof or wheel! Two Empresses that cordially hate one another, and that disagree on this very subject.

Kaunitz and his Empress are extremely skittish in the matter, and as if quite refuse it at first: "Zips will be better," thinks Kaunitz to himself; "Cannot we have, all to ourselves, a beautiful little cutting out of Poland in that part; and then perhaps, in league with the Turk, who has money, beat the Russians home altogether, and rule Poland in their stead, or 'share it with the Sultan,' as Reis-Effendi suggests ?" And the dismal truth is, though it was not known for years afterward, Kaunitz does about this time, in profoundest secret, actually make Treaty of Alliance with the Turk ("so many million Piastres to us, ready money, year by year, and you shall, if not by our mediating, then by our fighting, be a contented Turk"); and all along at the different Russian-Turk "Peace-Congresses," Kaunitz, while pretending to sit and mediate along with Prussia, sat on that far other basis, privately thwarting everything; and span out the Turk pacification in a wretched manner for years coming.
