suffering some disasters, the conductors of this series of expeditions were at last successful, and in 815 B.C. the title of "Warden of the Western Marches" was officially conferred on the ruler for the time being of this western state, who in 777 B.C. had the further honour of seeing one of his daughters married to the Emperor himself. This political move on the part of the Emperor was unwise, for it led indirectly to the Tartars, who were frequently engaged in war with the Warden, interfering in the quarrels about the imperial succession, in which question the Tartars naturally thought they had a right to interfere in the interests of their own people. The upshot of it was that in 771 B.C. the Emperor was killed by the Tartars in battle, and it was only by securing the military assistance of the semi-Tartar Warden of the Marches that the imperial dynasty was saved. As it was, the Emperor's capital was pe

But, before this conquest, the vassal princes of Chou had occupied practically the same territory, and had stood in the same relation to the imperial dynasty subsequently ousted by them in 1122, that the Wardens of the Marches occupied and stood in when the imperial house of Chou in turn fled east in

In other words, the population of China had grown so enormously, both by peaceful in-breeding and by imperceptible absorption of kindred races, that more elbow-room was needed; more freedom from the shackles of ritual, rank, and feudal caste; more independence, and more liberty to take advantage of local or changed traditions. Besides all this, the art of writing, though still clumsy, expensive, and confined in its higher and literary aspects to the governing classes, had recently become simplified and improved; the salt trade, iron trade, fish industry, silk indus
