Such taxes are or may be perfectly certain, or may be assessed so as to leave no doubt concerning either what ought to be paid, or when it ought to be paid; concerning either the quantity or the time of payment. Whatever uncertainty there may sometimes be, either in the duties of customs in Great Britain, or in other duties of the same kind in other countries, it cannot arise from the nature of those duties, but from the inaccurate or unskilful manner in which the law that imposes them is expressed.

Taxes upon luxuries generally are, and always may be, paid piecemeal, or in proportion as the contributors have occasion to purchase the goods upon which they are imposed. In the time and mode of payment they are, or may be, of all taxes the most convenient. Upon the whole, such taxes, are, perhaps, as agreeable to the three first of the four general maxims concerning taxation as any other. They offend in every respect against the fourth.

Such taxes, in proportion to what they bring into the public treasury of the state, always take out or keep out of the pockets of the people more than almost any other taxes. They seem to do this in all the four different ways in which it is possible to do it.

First, the levying of such taxes, even when imposed in the most judicious manner, requires a great number of custom-house and excise officers, whose salaries and perquisites are a real tax upon the people, which brings nothing into the treasury of the state. This expense, however, it must be acknowledged, is more moderate in Great Britain than in most other countries. In the year which ended on the 5th of July 1775, the gross produce of the different duties, under the management of the commissioners of excise in England, amounted to #5,507,308 18s. 8 1/4d., which was levied at an expense of little more than five and a half per cent. From this gross produce, however, there must be deducted what was paid away in bounties and drawbacks upon the exportation of excisable goods, which will reduce the net produce below five millions.* The levying of the salt duty, an excise duty, but under a different management, is much more expensive. The net revenue of the customs does not amount to two millions and a half, which is levied at an expense of more than ten per cent in the salaries of officers, and other incidents. But the perquisites of custom-house officers are everywhere much greater than their salaries; at some ports more than double or triple those salaries. If the salaries of officers, and other incidents, therefore, amount to more than ten per cent upon the net revenue of the customs, the whole expense of levying that revenue may amount, in salaries and perquisites together, to more than twenty or thirty per cent. The officers of excise receive few or no perquisites, and the administration of that branch of the revenue, being of more recent establishment, is in general less corrupted than that of the customs, into which length of time has introduced and authorized many abuses. By charging upon malt the whole revenue which is at present levied by the different duties upon malt and malt liquors, a saving, it is supposed, of more than fifty thousand pounds might be made in the annual expense of the excise. By confining the duties of customs to a few sorts of goods, and by levying those duties according to the excise laws, a much greater saving might probably be made in the annual expense of the customs. * The net produce of that year, after deducting all expenses and allowances, amounted to #4,975,652 19s. 6d.

Secondly, such taxes necessarily occasion some obstruction or discouragement to certain branches of industry. As they always raise the price of the commodity taxed, they so far discourage its consumption, and consequently its production. If it is a commodity of home growth or manufacture, less labour comes to be employed in raising and producing it. If it is a foreign commodity of which the tax increases in this manner the price, the commodities of the same kind which are made at home may thereby, indeed, gain some advantage in the home market, and a greater quantity of domestic industry may thereby be turned toward preparing them. But though this rise of price in a foreign commodity may encourage domestic industry in one particular branch, it necessarily discourages that industry in almost every other. The dearer the Birmingham manufacturer buys his foreign wine, the cheaper he necessarily sells that part of his hardware with which, or, what comes to the same thing, with the price of which he buys it. That part of his hardware, therefore, becomes of less value to him, and he has less encouragement to work at it. The dearer the consumers in one country pay for the surplus produce of another, the cheaper they necessarily sell that part of their own surplus produce with which, or, what comes to the same thing, with the price of which they buy it. That part of their own surplus produce becomes of less value to
