As has been said, on the west the steppe of Pamir and on the east the desert of Gobi present distinct and secure defences against aggression from without in those directions. There are few states in Asia with a more clearly marked position than that of which we have been speaking. Nature seems to have formed it to lead an isolated and independent existence, happy and prosperous in its own resources and careless of the outer world; but its history has been of a more troubled character, and at only brief intervals has its natural wealth been so fostered as to make it that which it has been called, "the Garden of Asia." This condition of almost continual warfare and disturbance during centuries, has left many visible marks on the external features of the country, and in nothing is this more strikingly evident than in the small population. A region which contains at the most moderate estimate 250,000 square miles, is believed by the highest authorities to contain less than 1,000,000 inhabitants. In breadth Kashgaria may be said to extend from longitude E. 73° to 89°, and in width from latitude N. 36° to 43°; but the ancient kingdom of Kashgar has been always considered to have reached only to Aksu, a town about 300 miles north-east of Kashgar. When the Chinese about fifty years ago conceded certain trade privileges to Khokand, they were not to have effect east of Aksu; this fact seems conclusive as to the recognized limits of the ancient dynasty of Kashgar. The capital of this district, which at one time has been a flourishing kingdom under a native ruler, at another a tributary of some Tartar conqueror, and then distracted by the struggles of his effete successors, and at a third time a subject province of the Chinese, has fluctuated as much as the fortunes of the state itself. Now it has been Yarkand, now Kashgar, and yet again, on several occasions, Aksu. The claims of Kashgar seem to have prevailed in the long run, for, although Yarkand is still the larger city, Yakoob Beg established his capital at Kashgar, and made that town known throughout the whole of Asia by the means of his government.
