It may seem wonderful, that the Author of these Letters makes mention in his former, of a kind of War between theOriental Tartarsand theMuscovites, notwithstanding the extream distance these People appear to be from one another in our Geographical Charts; but those who know how much theMuscoviteshave extended the Bounds of the Empire along theTartarianSea, will judge the thing less difficult, besides those who have seen these Countries, have made Discoveries much differing from those which our Geographers have informed us of hitherto. Very latelyMonsieur D'Arcy, who commands one of the King's Ships, in the Fleet ofMonsieur Le Marescal d'Estrees, informed us, that having served inPoland, and having been made Governor of a Place towardsMoscovy, theMoscoviteAmbassadors in their return having pass'd by him, and being by him treated in such a manner as put them into a very good Humour; one of them shewed him a Chart of the Countries betweenMoscovyandChina: and told him, that from three Cities which he shewed him, whose Names wereLopsla,Abasinko,Nerginsko, all three under the Governmentof the great Dukes, tho' situated in the greatTartary, there was a way toPekin, which was not more than 25 or 30 Days Journey. This Map it seems must be kept very secret inMoscovy: For the next Day theMoscovitewas in despair, for having given it, saying that if it should be known, he should come to great Damage. The Officer being come back since intoFrance, has given a Copy to the King, and another toMonsieur Le Marquis de Signelay. To confirm this, it may be added, what aFrenchMan has writ fromMoscovywithin this two Months, that they are actually raising Troops to go to War with theChinese.
