and by procuring to both the most extensive market for every part of their produce, in consequence of establishing the easiest and safest communications both by land and by water, through every part of his own dominions, as well as the most unbounded freedom of exportation to the dominions of all other princes.
If by such a system of administration a tax of this kind could be so managed as to give, not only no discouragement, but, on the contrary, some encouragement to the improvement of land, it does not appear likely to occasion any other inconvenience to the landlord, except always the unavoidable one of being obliged to pay the tax.
In all the variations of the state of the society, in the improvement and in the declension of agriculture; in all the variations in the value of silver, and in all those in the standard of the coin, a tax of this kind would, of its own accord and without any attention of government, readily suit itself to the actual situation of things, and would be equally just and equitable in all those different changes. It would, therefore, be much more proper to be established as a perpetual and unalterable regulation, or as what is called a fundamental law of the commonwealth, than any tax which was always to be levied according to a certain valuation.

Domesday-book seems to have been the result of a very accurate survey of this kind.
