In 746 B.C. the state of Ts'in, which had just then recently emerged from Tartar barbarism, and had settled down permanently in the old imperial domain, first introduced the "three stock" law, under which the three generations, or the three family connections of a criminal were executed for his crime as well as himself. In 596 and 550 Tsin (which thus seems to have taken the hint from Ts'in) exterminated the families of two political refugees who had fled to the Tartars and to Ts'i respectively. Even in Ts'u the relatives of the man who first taught war to Wu were massacred in 585, and any one succouring the fugitive King of Ts'u was threatened with "three clan penalties"; this last case was in the year 529. The laws of Ts'u seem to have been particularly harsh; in 55 the premier was cut into four for corruption, and one quarter was sent in each direction, as a warning to the local districts. About 650 B.C. a distinguished Lu statesman, named Tsang Wen-chung, seems to have drawn up a special code, for one of Confucius' pupils (two centuries later) denounced it as being too severe when compared with Tsz-ch'an's mild laws--to be soon mentioned. Confucius himself also described the man as being "too showy." This Lu statesman, about twenty years later, made some significant and informing observations to the ruler of Lu when report came that Tsin (the Second Protector) was endeavouring to get the Emperor to poison a federal refugee from Wei, about whose succession the powers were at the moment quarrelling. He said: "There are only five recognized punishments: warlike arms, the axe, the knife or the saw, the branding instruments, the whip or the bastinado; there are no surreptitious ones like this now proposed." The result was that Lu, being of the same clan as the Emperor, easily succeeded in bribing the imperial officials to let the refugee prince go. The grateful prince eagerly offered Tsang W&n-chung a reward; but the statesman declined to receive it, on the ground that "a subject's sayings are not supposed to be known beyond his own master's frontier." About, a century later a distinguished Tsin statesman, asking what "immortality" meant, was told: "When a man dies, but when his words live; like the words of this distinguished man, Tsang W&n-chung, of Lu state." This same Tsin statesman is said to have engraved some laws on iron (513), an act highly disapproved by Confucius. It is only by thus piecing together fragmentary allusions that we can arrive at the conclusion that "there were judges in those days." Mention has been several times made in previous chapters of Tsz-ch'an, whose consummate diplomacy maintained the independence and even the federal influence of the otherwise obscure state of Cheng during a whole generation. In the year 536 B.C. he decided to cast the laws in metal for the information of the people: this course was bitterly distasteful to his colleague, Shuh Hiang of Tsin (see
