[Sidenote: Narue.] The like fell out at the port of Narue in Liefland, where his sonne Iuan Vasiliwich deuised to build a towne, and a castle on the other side the riuer, (called Iuanogrod) to keepe the towne and countrey in subiection. The castle he caused to be so built and fortified, that it was thought to be inuincible. And when it was furnished, for reward to the Architect (that was a Polonian) he put out both his eyes, to make him vnable to build the like againe. But hauing left the natiues all within their owne countrey, without abating their number or strength, the towne and castle not long after was betraied, and surrendred againe to the king of Sweden. On the Southeast side they haue got the kingdomes of Cazan, and Astracan. These were wonne from the Tartar, by the late Emperour Iuan Vasiliwich, the one about thirtie fiue, the other about thirtie and three yeares agoe. [Sidenote: Siberia and Ob. Conquest of a 1000 miles.] Northward out of the countrey of Siberia, he hath layed vnto his realme a great breadth and length of ground, from Wichida to the riuer of Obba, about a thousand miles space: so that he is bolde to write himselfe now, The great Commander of Siberia. [Sidenote: Premia and Pechora] The countries likewise of Permia, and Pechora are a diuers people and language from the Russe, ouercome not long since, and that rather by threatning, and shaking of the sword, then by any actual force: as being a weake and naked people, without meanes to resist. That which the Russe hath in his present possession, he keepeth on this sort. [Sidenote: Means of holding chief townes.] In his foure chief border townes of Vobsko, Smolensko, Astracan, and Cazan, he hath certaine of his counsel not of the greatest nobility, but of greatest trust, which haue more authoritie within their precincts, (for the countenancing and strengthening of their gouernment there) then the other Dukes that are set to gouerne in other places, as was noted before, in the maner of ordering their Prouinces. These he changeth sometimes euery second or third yere, but exceedeth not that time, except vpon very speciall trust, and good liking of the party, and his seruice: least by enlarging of their time, they might grow into some familiaritie with the enemie (as some haue done) being so farre out of sight. The townes besides are very strongly fenced with trenches, castles, and store of munition, and haue garisons within them, to the number of two or three thousand a piece. They are stored with victual if any seige should come vpon them, for the space of two or three yeres before hand. The foure castles of Smolensko, Vobsko, Cazan and Astracan, he hath made very strong to beare out any siege: so that it is thought that those townes are impregnable.
