446 might be as unobjectionable as most other taxes; but if cane sugar, having previously been cheaper than beet-root sugar, was now dearer, and beet-root sugar was to any considerable amount substituted for it, and fields laid out and manufactories established in consequence, the government would gain no revenue from the beet-root sugar, while the consumers of it would pay a real tax. They would pay for beet-root sugar more than they had previously paid for cane sugar, and the difference would go to indemnify producers for a portion of the labour of the country actually thrown away, in producing by the labour of (say) three hundred men, what could be obtained by the other process with the labour of two hundred.

One of the commonest cases of discriminating duties, is that of a tax on the importation of a commodity capable of being produced at home, unaccompanied by an equivalent tax on the home production. A commodity is never permanently imported, unless it can be obtained from abroad at a smaller cost of labour and capital on the whole, than is necessary for producing it. If, therefore, by a duty on the importation, it is rendered cheaper to produce the article than to import it, an extra quantity of labour and capital is expended, without any extra result. The labour is useless, and the capital is spent in paying people for laboriously doing nothing. All custom duties which operate as an encouragement to the home production of the taxed article, are thus an eminently wasteful mode of raising a revenue.

This character belongs in a peculiar degree to custom duties on the produce of land, unless countervailed by excise duties on the home production. Such taxes bring less into the public treasury, compared with what they take from the consumers, than any other imposts to which civilized nations are usually subject. If the wheat produced in a country is twenty millions of quarters, and the consumption twenty-one millions, a million being annually imported, and if on this million a duty is laid which raises the price ten shil-
