K'u-ch'e

A so-called "Ferghana Series" of oil-bearing strata runs into Kashgaria from Russian Turkestan and extends along the foot of the T'ien Shan past Aqsu to Kucha (K'u-ch'e). What may be an extension of this same series reappears again in the region of the Sinkiang North Road.

Responsibility for this control was in the hands of the Hsi-an Military Governor situated at what was called Chiu-tzu, the present-day K'u-ch'e (Kucha) in the southern piedmont of the T'ien Shan southwest of Urumchi.
