I divide, therefore, modern taxes into three classes. 1. Those upon alienation, which I call proportional: 2. Those upon possessions, which I call cumulative or arbitrary: and 3. Those exacted in service, which I call personal. These terms must now be fully explained, that I may use them hereafter without being misunderstood.

A proportional tax presents a simple notion.

It is paid by the buyer, who intends to consume, at the time of the consumption, while the balance of wealth is turning against him; and is consolidated with the price of the commodity.

Examples of this tax are all excises, customs, stamp-duties, postage, coinage, and the like.

By this definition, two requisites are necessary for fixing the tax upon any one: first, he must be a buyer; secondly, he must be a consumer. Let this be retained.

A cumulative or arbitrary tax, presents various ideas at first sight, and cannot well be defined until the nature of it has been illustrated by examples.

It may be known, 1mo, By the intention of it; which is to affect the possessor in such a manner as to make it difficult for him to augment his income, in proportion to the tax he pays.

2do, By the object, when instead of being laid upon any determinate piece of labour or consumption, it is made to affect past and not present gains.

3tio, By the circumstances under which it is levied, which imply no transition of property from hand to hand, nor any change in the balance of wealth between individuals.

Examples of cumulative taxes are land-taxes, poll-taxes, window-taxes, duties upon coaches and servants, that upon industrie, in France, and many others.
