 upon profit; thirdly, of those which, it is intended, should fall upon wages; and, fourthly, of those which, it is intended, should fall indifferently upon all those three different sources of private revenue. The particular consideration of each of these four different sorts of taxes will divide the second part of the present chapter into four articles, three of which will require several other subdivisions. Many of those taxes, it will appear from the following review, are not finally paid from the fund, or source of revenue, upon which it was intended they should fall.

Before I enter upon the examination of particular taxes, it is necessary to premise the four following maxims with regard to taxes in general.

I. The subjects of every State ought to contribute toward the support of the government, as nearly as possible, in proportion to their respective abilities; that is, in proportion to the revenue which they respectively enjoy under the protection of the State. The expense of government to the individuals of a great nation, is like the expense of management to the joint tenants of a great estate, who are all obliged to contribute in proportion to their respective interests in the estate. In the observation or neglect of this maxim consists what is called the equality or inequality of taxation. Every tax, it must be observed once for all, which falls finally upon one only of the three sorts of revenue above mentioned, is necessarily unequal, in so far as it does not affect the other two. In the following examination of different taxes I shall seldom take much further notice of this sort of inequality, but shall, in most cases, confine my observations to that inequality which is occasioned by a particular tax falling unequally upon that particular sort of private revenue which is affected by it.
