SOURCES. GENERAL MAP OF SIBERIA. 1765
Nine administrative subdivisions are in Old Siberia: Pelym, Verchoturye, Yekaterinburg, Turinsk, Tyumen and Tobolsk uezds, province of Iset, district of Yalutorovsk. Redoubts and fortresses of ‘New Ishim border line’. fortresses of ‘Irtysh border line’, ‘Steppe of nomadic Kirgiskaisaks’. Thirteen uezds in the rest of Siberia. Cities, slobodas and villages at well known (for descriptor) parts are situated pretty rough: regular mix ups of the river banks, some important settlements are absent, some small random points may appear on the map.
