The Rashīdī History 7.1.5

7.1.5

From the Tarbagatai range, the limiting line would probably bend south-eastward to some point at the northern foot of the Tian Shan, near the present Urumtsi; but this is somewhat uncertain. All that is clear is that the tract now known as "Zungaria" (or the land of the Zungar, or Jungar, Kalmaks) formed a part of the Moghul dominion, but how far precisely, "Zungaria" extended towards the east, there is nothing to show. Probably it included Lakes Ebi Nor and Ayar Nor, and had for its central feature the upper course of the Ili river. On the south, the main range of the Tian Shan, as far west as about the head of the Narin river, divided Moghulistan from Kuchar, Aksu, etc., while westward, again, the water-parting ranges between the Narin and Lake Issigh-Kul, continued up to the heads of the Talas, would seem, approximately, to have been the line of separation from Kashghar and Farghana.
