These warlike amusements did not take off the czar's attention to his naval project. As he had made Le Fort a general by land, notwithstanding his having never borne a command; he now made him admiral, though he had never had the direction of a ship, but he knew him deserving both of the one and the other. It is true, that he was an admiral without a fleet, and a general with only his regiment for an army. By degrees the czar reformed that great abuse in the army, viz. the independence of the boyards, who, in time of war, used to bring into the field a multitude of their vassals and peasants: this was exactly the ancient government of the Franks, Huns, Goths, and Vandals, who indeed subdued the Roman empire in its state of decline, but would have been totally destroyed, had they had the warlike disciplined legions of ancient Rome to encounter, or such armies as are now brought into the field. Admiral Le Fort was not long, however, before he had something more than an empty title. He employed some Dutchmen and Venetians in building a number of barcolongos, or kind of long barks, and also two ships of about thirty guns each, at the mouth of the Woronitz, which falls into the Tanais, or Don: these vessels were to fall down the river, and keep in awe the Crim Tartars, with whom hostilities had been renewed. The czar was now to determine (in 1689) against which of the following powers he would declare war, whether against the Turks, the Swedes, or the Chinese. But here it will be proper to premise on what terms he then stood with China, and which was the first treaty of peace concluded by that nation. CHAP. VII. Congress and Treaty with the Chinese.[34] We must set out by forming a proper idea of the limits of the Chinese and Russian empires at this period. When we leave Siberia, properly so called, and also far behind us to the south, a hundred hordes of Tartars, with white and black Calmucks, and Mahometan and Pagan Monguls, we come to the 130th degree of longitude, and the 52d of latitude upon the river Amur.[35] To the northward is a great chain of mountains, that stretches as far as the Frozen Sea, beyond the polar circle. This river, which runs upwards of five hundred leagues,[36] through Siberia and Chinese Tartary, falls, after many windings, into the sea of Kamtshatka. It is affirmed for a truth, that at its mouth, which opens with this sea, there is sometimes caught a monstrous fish, much larger than the hippopotamus of the Nile, and that the tooth thereof is the finest ivory. It is furthermore said, that this ivory was formerly an object of trade; that they used to convey it through Siberia, which is the reason why several pieces of it are still found under the ground in that country. This is the most probable account of the fossil ivory, of which we have elsewhere spoken; for it appears highly chimerical to pretend, that there were formerly elephants in Siberia.
