had got their hand well in with generations of fighting against barbarians--Tartars, Tunguses, Annamese, Shans, and what not--and had invigorated themselves with good fresh barbarian blood. The fact is, the population of China had enormously increased; the struggle for life and food was keener; the old patriarchal appetite for ritual was disappearing; the people were beginning to assert themselves against the land-owners; the land-owners were encroaching upon the power of the ruling princes; and China was in a parlous state. CHAPTER IX POSITION OF ENVOYS It was a fixed rule in ancient China that envoys should be treated with courtesy, and that their persons should be held sacred, whether at residential courts, in durbar, or on the road through a third state. During the wars of the sixth century B.C. between Tsin in the north and Ts'u in the south, when these two powers were rival aspirants to the Protectorate of the original and orthodox group of principalities lying between them, and were alternately imposing their will on the important and diplomatic minor Chinese state of CHÊNG (still the name of a territory in Ho Nan), there were furnished many illustrations of this recognized rule. The chief reason for thus making a fighting-ground of the old Chinese principalities was that it was almost impossible for Ts'u to get conveniently at any of the three great northern powers, and equally difficult for Ts'in, Tsin, and Ts'i to reach Ts'u, without passing through one or more Chinese states, mostly bearing the imperial clan name, and permission had to be asked for an army to pass through, unless the said Chinese state was under the predominancy of (for instance) Tsin or Ts'u. It was like Germany and Italy with Switzerland between them, or Germany and Spain with France between them. Another important old Chinese state was Sung, lying to the east of CHÊNG. Both these states were of the highest caste, the Earl of CHÊNG being a close relative of the Chou Emperor, and the Duke of Sung being the representative or religious heir of the remains of the Shang dynasty ousted by the Chou family in I 122 B.C., magnanimously reinfeoffed "in order that the family sacrifices might not be entirely cut off" together with the loss of imperial sway. In the year 595 B.C. Sung went so far as to put a Ts'u envoy to death, naturally much to the wrath of the rising southern power. Ts'u in turn arrested the Tsin envoy on his way to Sung, and tried in vain to force him to betray his trust. In 582 Tsin, in a fit of anger, detained the CHÊNG envoy, and finally put him to death for his impudence in coming officially to visit Tsin after coquetting with Tsin's rival Ts'u. All these irregular cases are severely blamed by the historians. In 562 Ts'u turned the tables upon Tsin by putting the CHÊNG envoy to death after the latter had concluded a treaty with Tsin. Confucius joins, retrospectively of course, in the chorus of universal reprobation.
