In return for these Russian sons of Anak, Friedrich Wilhelm grudged not to send German smiths, millwrights, drill-sergeants, cannoneers, engineers; having plenty of them. By whom, as Peter well calculated, the inert opaque Russian mass might be kindled into luminosity and vitality; and drilled to know the Art of War, for one thing. Which followed accordingly. And it is observable, ever since, that the Russian Art of War has a tincture of GERMAN in it (solid German, as contradistinguished from unsolid Revolutionary-French); and hints to us of Friedrich Wilhelm and the Old Dessauer, to this hour.--EXEANT now the Barbaric semi-fabulous Sovereignties, till wanted again. Chapter VIII. -- THE CROWN-PRINCE IS PUT TO HIS SCHOOLING. In his seventh year, young Friedrich was taken out of the hands of the women; and had Tutors and Sub-Tutors of masculine gender, who had been nominated for him some time ago, actually set to work upon their function. These we have already heard of; they came from Stralsund Siege, all the principal hands. Duhan de Jandun, the young French gentleman who had escaped from grammar-lessons to the trenches, he is the practical teacher. Lieutenant-General Graf Fink von Finkenstein and Lieutenant-Colonel von Kalkstein, they are Head Tutor (OBERHOFMEISTER) and Sub-Tutor; military men both, who had been in many wars besides Stralsund. By these three he was assiduously educated, subordinate schoolmasters working under them when needful, in such branches as the paternal judgment would admit; the paternal object and theirs being to infuse useful knowledge, reject useless, and wind up the whole into a military finish. These appointments, made at different precise dates, took effect, all of them, in the year 1719. Duhan, independently of his experience in the trenches, appears to have been an accomplished, ingenious and conscientious man; who did credit to Friedrich Wilhelm's judgment; and to whom Friedrich professed himself much indebted in after life. Their progress in some of the technical branches, as we shall perceive, was indisputably unsatisfactory. But the mind of the Boy seems to have been opened by this Duhan, to a lively, and in some sort genial, perception of things round him;--of the strange confusedly opulent Universe he had got into; and of the noble and supreme function which Intelligence holds there; supreme in Art as in Nature, beyond all other functions whatsoever. Duhan was now turned of thirty: a cheerful amiable Frenchman; poor, though of good birth and acquirements; originally from Champagne. Friedrich loved him very much; always considered him his spiritual father; and to the end of Duhan's life, twenty years hence, was eager to do him any good in his power. Anxious always to repair, for poor Duhan, the great sorrows he came to on his account, as we shall see.
