public revenue of China, however, is said to be paid in this manner. The mandarins and other tax-gatherers will, no doubt, find their advantage in continuing the practice of a payment, which is so much more liable to abuse than any payment in money.
A tax upon the produce of land, which is levied in money, may be levied, either according to a valuation, which varies with all the variations of the market price; or according to a fixed valuation, a bushel of wheat, for example, being always valued at one and the same money price, whatever may be the state of the market. The produce of a tax levied in the former way will vary only according to the variations in the real produce of the land, according to the improvement or neglect of cultivation. The produce of a tax levied in the latter way will vary, not only according to the variations in the produce of the land, but according both to those in the value of the precious metals, and those in the quantity of those metals which is at different times contained in coin of the same denomination. The produce of the former will always bear the same proportion to the value of the real produce of the land. The produce of the latter may, at different times, bear very different proportions to that value.
