“ Another mountain-complex of much lower elevation runs north-westwards from the Trans-Ili Ala-tau towards the southern extremity of Lake Balkash. In the north, where the province borders Semipalatinsk, it includes the western parts of the Tarbagatai range, the summits of which (10,000 ft.) do not reach the limit of perpetual snow. The remainder of the province consists of a fertile steppe in the north-east (Sergiopol) , and vast uninhabitable sand-steppes on the south of Lake Balkash. ”
