His chief and most important argument was, not that it would be a good thing in itself, but that it would be perfectly impossible to prevent it by any means the government could adopt; and also that foreign trade generally was of importance to China, from the revenue which it produced, and the employment which it gave to the people. He shewed how totally ineffectual every increase of punishment, even to death itself, had proved, for the prevention of the practice, which, on the contrary, had increased tenfold; and he then went on to make it evident that "when opium was purchased secretly, it could only be exchanged with silver; but that, if it were permitted to be bought openly, it would be paid for in the productions of the country." And he cleverly adds: "the dread of the laws is not so great among the people as the _love of gain_, which unites them to all manner of crafty devices, so that sometimes the law is rendered wholly ineffective." But he would still prohibit all public officers, scholars, and soldiers, from using it, under pain of instant dismissal from the public service. It is known that the Empress received this recommendation with particular favour, but the Emperor referred it for the consideration of the crafty old Tang, the Governor of Canton, who was at the very time deriving a large revenue from winking at the clandestine sale of the drug. The answer of Tang and his colleagues was decidedly favourable to the project. They declared that "_the circumstances of the times_ rendered a change in the regulations necessary." They openly admitted that the payment of distinct duties would be far less onerous than the payment of _bribes_; that the laws could then be administered, and would be _respected_; and that the precious metals which were now oozing out of the empire would then be retained in it. They even went so far as to say that the _dignity_ of the government would by no means be lowered by it; and they farther declared that the prohibition of the luxury made it more eagerly sought for. Here, then, was clearly another triumph on the Empress's side; and those who were opposed to her principles feared it as such, and redoubled their efforts to produce her fall. But the recommendation did not even stop at that point; for it went so far as even to encourage the cultivation and preparation of the poppy within the empire, in order to exclude a portion of the foreign article from the market. One might have supposed that the influences which were now at work to produce a better state of foreign trade, backed by the countenance of the Empress, and supported by the apparent neutrality of the Emperor, would have sufficed to occasion some modification in the existing laws.
