Rh of values, some falling, others rising, owing to a circumstance, the effect of which on values and prices we formerly discussed; the different durability of the capital employed in different occupations. The gross produce of industry consists of two parts; one portion serving to replace the capital consumed, while the other portion is profit. Now equal capitals in two branches of production must have equal expectations of profit; but if a greater portion of the one than of the other is fixed capital, or if that fixed capital is more durable, there will be a less consumption of capital in the year, and less will be required to replace it, so that the profit, if absolutely the same, will form a greater proportion of the annual returns. To derive from a capital of 1000l. a profit of 100l., the one producer may have to sell produce to the value of 1100l., the other only to the value of 500l. If on these two branches of industry a tax be imposed of five per cent ad valorem, the last will be charged only with 25l., the first with 55l.; leaving to the one 75l. profit, to the other only 40l. To equalize, therefore, their expectation of profit, the one commodity must rise in price, or the other must fall, or both: commodities made chiefly by immediate labour must rise in value, as compared with those which are chiefly made by machinery. It is unnecessary to prosecute this branch of the inquiry any further.

§ 2.A tax on any one commodity, whether laid on its production, its importation, its carriage from place to place, or its sale, and whether the tax be a fixed sum of money for a given quantity of the commodity, or an ad valorem duty, will, as a general rule, raise the value and price of the commodity by at least the amount of the tax. There are few cases in which it does not raise them by more than that amount In the first place, there are few taxes on production on account of which it is not found or deemed necessary to impose restrictive regulations on the manufacturers or dealers, in order to check evasions of the tax. These regu-
