On calling there with Mr. Fonblanque, I found a tall military-looking man, between forty and forty-five years of age. He entered at once, and without mystery, into the subject of his mission, and concluded by saying that "Servia owed her political existence solely to Russia, which gave the latter a moral right of intervention over and above the stipulations of treaties, to which no other power could pretend." As the public is already familiar with the arguments pro and contra on this question, it is at present unnecessary to recur to them. Baron Lieven had in the posture of affairs at that time a difficult part to play, inasmuch as a powerful party sought to throw off the protectorate of Russia. The baron, without possessing an intellect of the highest order, was a man of good sound judgment, and in his proceedings showed a great deal of frankness and military decision, qualities which attained his ends in all probability with greater success than if he had been endowed with that profound astuteness which we usually attribute to Russians. This was his fifth mission into the Turkish dominions; so that, although not possessing the language, he was yet well acquainted with the Turkish character and Eastern affairs in general. His previous mission had for its object to announce to the Sultan that, in accordance with the stipulations of the treaty of the 15th of July, 1840, the military and naval forces of the Emperor of Russia were at the service of his Highness. Baron Lieven was accompanied to Servia by his lady, a highly talented person, who spoke English admirably; and the evenings spent in his hospitable house were among the most agreeable reminiscences of my residence at Belgrade. The stationary Russian consul-general was M. Wastchenko, a stout middle-aged gentleman, with the look of a well-conditioned alderman. M. Wastchenko had been originally in a commercial establishment at Odessa; but having acquired a knowledge of the Turkish language he was attached to the embassy at Constantinople, and subsequently nominated Russian consul at Belgrade, under the consul-general for the principalities of Wallachia and Moldavia; but his services having been highly approved by Count Nesselrode, he was advanced to the rank and pay of consul-general. M. Wastchenko possesses in an eminent degree what Swift calls the aldermanly, but never to be over estimated quality, Discretion; he was considered generally a very safe man. In fact, a sort of man who is a favourite with all chanceries; the quality of such a mind being rather to avoid complications than to excite admiration by activity in the pen or the tongue. M. Wastchenko was most thoroughly acquainted with everything, and every man, in Servia. He spoke the language fluently, and lived familiarly with the principal persons in Belgrade. He had never travelled in Europe, and, strange to say, had never been in St. Petersburg.
