It is not to be inferred from this view of tithes, and taxes on the land and its produce, that they do not discourage cultivation. Every thing which raises the exchangeable value of commodities of any kind, which are in very general demand, tends to discourage both cultivation and production; but this is an evil inseparable from all taxation, and is not confined to the particular taxes of which we are now speaking. This may be considered indeed as the unavoidable disadvantage attending all taxes received and expended by the state. Every new tax becomes a new charge on production, and raises natural price. A portion of the labour of the country which was before at the disposal of the contributor to the tax, is placed at the disposal of the state. This portion may become so large, that sufficient surplus produce may not be left to stimulate the exertions of those who usually augment by their savings the capital of the state. Taxation has happily never yet in any free country been carried so far as constantly from year to year to diminish its capital. Such a state of taxation could not be long endured; or if endured, it would be constantly absorbing so much of the annual produce of the country as to occasion the most extensive scene of misery, famine, and depopulation. "A land-tax," says Adam Smith, "which like that of Great Britain, is assessed upon each district according to a certain invariable canon, though it should be equal at the time of its first establishment, necessarily becomes unequal in process of time, according to the unequal degrees of improvement or neglect in the cultivation of the different parts of the country. In England the valuation according to which the different counties and parishes were assessed to the land-tax by the 4th. William and Mary, was very unequal, even at its first establishment. This tax, therefore, so far offends against the first of the four maxims above mentioned. It is perfectly agreeable to the other three. It is perfectly certain. The time of payment for the tax being the same as that for the rent, is as convenient as it can be to the contributor. Though the landlord is in all cases the real contributor, the tax is commonly advanced by the tenant, to whom the landlord is obliged to allow it in the payment of the rent."
