Taxes upon the produce of land may be levied, either in kind, or, according to a certain valuation, in money.
The parson of a parish, or a gentleman of small fortune who lives upon his estate, may sometimes, perhaps, find some advantage in receiving, the one his tithe, and the other his rent, in kind. The quantity to be collected, and the district within which it is to be collected, are so small that they both can oversee, with their own eyes, the collection and disposal of every part of what is due to them. A gentleman of great fortune, who lived in the capital, would be in danger of suffering much by the neglect, and more by the fraud of his factors and agents, if the rents of an estate in a distant province were to be paid to him in this manner. The loss of the sovereign, from the abuse and depredation of his tax-gatherers, would necessarily be much greater. The servants of the most careless private person are, perhaps, more under the eye of their master than those of the most careful prince; and a public revenue, which was paid in kind, would suffer so much from the mismanagement of the collectors that a very small part of what was levied upon the people would ever arrive at the treasury of the prince. Some part of the 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
