Marischal continued in Spain, corresponding, sending news (the Prussian Archives alone know what), for nearly a couple of years. [Returned "April, 1762" (Friedrich's Letter to him, "10th April, 1762:" in _OEuvres de Frederic,_ xx. 285).] His Embassy had one effect, which is of interest to us here. On his way out, he had gone by London, with a view of getting legal absolution for his Jacobitism,--so far, at least, as to be able to inherit the Earldom of Kintore, which is likely to fall vacant soon. By blood it is his, were the Jacobite incapacities withdrawn. Kintore is a cadet branch of the Keiths; "John, younger Son of William Sixth Lord Marischal," was the first Kintore. William Sixth's younger Son, yes;--and William's Father, a man always venerable to me, had (A.D. 1593) founded Marischal College, Aberdeen,--where, for a few, in those stern granite Countries, the Diviner Pursuits are still possible (thank God and this Keith) on frugal oatmeal. MARISCHAL-COLLEGE Keith, or FIFTH Lord Marischal, was grandfather's grandfather of our Potsdam Friend, who is tenth and last. [Douglas's _Scotch Peerage,_ pp. 448 et seq., 387 et seq.] Honor to the brave and noble, now fallen silent under foot NOT of the nobler! In a word, the fourth Kintore was about dying childless; and Marischal had come by London on that heritage business. He carried, naturally, the best recommendations. Britannic Majesty, Pitt and everybody met him with welcome and furtherance; what he wished was done, and in such a style of promptness and cordiality, Pitt pushing it through, as quite gained the heart of old Marischal. And it is not doubted, though particulars have not been published, That he sent important Spanish notices to Pitt, in these years;-and especially informed him that King Carlos and the French Bourbon had signed a FAMILY COMPACT (15th August, 1761), or solemn covenant, to stand by one another as brothers. Which was thenceforth, to Pitt privately, an important fact, as perhaps we shall see; though to other men it was still only a painful rumor and dubiety. Whether the old Marischal informed him, That King Carlos hated the English; that he never had, in his royal mind, forgiven that insult of Commodore Martin's (watch laid on the table, in the Bay of Naples, long ago), I do not know; but that also was a fact. A diligent, indignant kind of man, this Carlos, I am told; by no means an undeserving King of Spain, though his Portraits declare him an ugly: we will leave him in the discreet Marischal's hands, with the dear Old Friend shining equally on both.
